MEMORANDUM OPINION

THYNGE, United States Magistrate Judge.

I. INTRODUCTION

This is a patent infringement case. On June 4, 2002, Inline Communication Corporation^[1] ("Inline")^[2] filed suit against EarthLink, Inc. ("EarthLink"),^[3] alleging infringement of U.S. Patent Nos. 5,844,596 ("the '596 patent"), 6,243,446 ("the '446 patent"), and 6,236,718 ("the 718 patent").^[4] Inline's U.S. Patent No. 6,542,585 ("the '585 patent") was subsequently added to the litigation after it issued in 2003.^[5]

The trial in this matter began on February 7, 2007. At trial, Inline asserted infringement of claim 61 of the '596 patent; claims 1, 2, 3, 4, and 5 of the '446 patent; and claims 1, 2, 4, 8, and 9 of the '585 patent. EarthLink denied infringement and alleged that the asserted claims were anticipated and obvious, and that the patents failed to comply with written description and enablement requirements of 35 U.S.C. § 112. After the close of all evidence on February 13, 2007, Inline moved for judgment as a matter of law under Fed.R.Civ.P. 50(a). On February 15, 2007, the jury returned a verdict of non-infringement and that the each asserted claims were invalid as anticipated and obvious and that each of the patents failed to comply with the written description and enablement requirements of section 112.^[6] Currently before the court is Inline's renewed motion for judgment as a matter of law under Rule 50(a), or in the alternative for a new trial pursuant to Rule 59(a).^[7] Inline contends that there is no legally sufficient basis to support any of the jury's findings and, therefore, its motion should be granted.^[8]

II. BACKGROUND

The technology in this case involves a system of transmitting high frequency data signals and lower frequency voice band signals over conventional telephone wiring. EarthLink, at the time of the initial action, was one of the leading internet service providers ("ISPs"). Inline alleged that EarthLink used its patented system, without permission, to make DSL products more attractive to consumers. According to Inline, although alternatives to the DSL products offered by EarthLink exist, using the Inline system allows products to be offered without incurring installation charges every time a new DSL customer is added, merely by having the customer "self-install" filters and modem devices within the home.

In addition to providing DSL services, EarthLink offers subscribers internet access through "dial-up" service. Initially, ISPs provided internet access only through dial-up service. Like DSL service, dial-up service allows computer users to access the internet via telephone lines. In order to connect to the internet using dial-up service, residential users may open an account with an ISP and are then provided with one or more telephone numbers linked to the ISP's computer. The dial-up modem is used to connect the user's computer to the ISP's computer, which in turn is connected to the internet.

However, dial-up internet service has limitations, which may be remedied by using DSL service. If dial-up service is being used to connect to the internet, the telephone line cannot simultaneously be used to send telephone voice signals. Thus, dial-up service users cannot make and receive telephone calls while connected to the internet. Additionally, computers have the capability to connect to the internet and communicate data at a higher rate than the rate afforded by a dial-up modem. The theoretical limit at which dial-up modems can exchange data over a conventional dial-up telephone connection is approximately 56,000 bits per second ("56 Kbps"). As a result, a 56K modem may be limited in the speed of transferring data to users.

A. Asymmetric Digital Subscriber Line ("ADSL") Technology

One type of DSL technology is ADSL technology. ADSL is used as an alternative to dial-up internet service. At its most basic level, ADSL technology involves the high-speed transmission of packets of digital data back and forth from, among other things, the internet to a user's computer. ADSL technology takes advantage of the existing telephone networks used for telephone services to send digital data between the internet and a computer (and vice versa) at higher rates of speed than dial-up service.

Moreover, an ADSL link has a potentially different connection path to the internet than dial up service. An ADSL modem at a customer's residence connects to a companion modem at a central office, which, in turn, is connected to the internet through a central office computer. Unlike dial-up internet service, ADSL allows simultaneous transmission of low frequency voice signals and higher frequency digital data signals over the same telephone line to and from the public telephone network. Thus, the ADSL user may talk simultaneously on the telephone and connect to the internet via the same telephone line because the data and voice frequency ranges can be cleanly separated.

This arrangement permits higher data transmission rates than available on dial-up modems. As a result, ADSL is capable of using subscriber loops to communicate two-way voice signals, upstream data signals, and downstream data signals within different frequency bands. Data transfers can be optimized by allocating more of the frequency range to the data transfers from the central office to the customer than in the opposite direction. ADSL can download data as high as 1.5 million bits per second ("1.5 Mbps"), which is more than 25 times the speed of the maximum dial-up modem rate of 56 Kbps.

B. The Asserted Patented Invention

The three patents at issue at trial are directed toward transmitting data signals of different frequencies over conventional telephone wiring. Inline contends that the patents disclose a unique way of enhancing the plain old telephone system ("POTS") to distribute any type of information over telephone wires that traditionally carry telephone calls to a location. These patents describe a system for sharing a telephone wire between information signals, confined to different frequency ranges. The asserted system uses filters to essentially block voice signals at a voice frequency range and pass the information signals at an information frequency range, and vice versa.

The systems disclosed in the '596 family of patents include a signal interface that transmits information from an external source of information along the shared telephone wire to individual households. Inside a household, a transreceiver connected to the shared telephone wire receives information and converts it to data. The shared telephone wire remains connected to the telephone, which continues its traditional use of making and receiving telephone calls, except that filters are installed at the telephone to prevent interference with the high frequency information signals.

III. STANDARD OF REVIEW

A. Judgment as a Matter of Law

Judgment as a matter of law ("JMOL") is governed by Fed.R.Civ.P. 50. When evaluating a motion for JMOL, the court reviews the jury's decision to determine if it is reasonably supported by the evidence.^[9] To prevail on a motion for JMOL, the moving party "`must show that the jury's findings, presumed or express are not supported by substantial evidence or, if they were, that the legal conclusions implied [by] the jury's verdict cannot in law be supported by those findings.'"<sup>[10]</sup> "`Substantial' evidence is such relevant evidence from the record taken as a whole as might be acceptable by a reasonable mind as adequate to support the finding under review."^[11] Defined another way, substantial evidence is evidence that a reasonable individual might accept as supporting the jury's decision.^[12] To determine the sufficiency of the JMOL motion, a court must consider all of the evidence in a light most favorable to the non-movant,^[13] and must draw all inferences in favor of the non-moving party:

In assessing the sufficiency of the evidence the court must give the non-moving party, as the verdict winner, the benefit of all logical inferences that could be drawn from the evidence presented, resolve all conflicts in the evidence in his favor, and in general, view the record in the light most favorable to him.^[14]

The court may not determine the credibility of witnesses nor substitute its account of the facts for that of the jury's account.^[15] Motions for JMOL are granted "sparingly" and only in those circumstances in which "the record is critically deficient of the minimum quantum of evidence in support of the verdict."^[16] Moreover, "[a] district court may overturn a jury's verdict only if upon the record before the jury, reasonable jurors could not reach that verdict."^[17]

While the jury's factual findings receive deference on a motion for JMOL, the "legal standards that the jury applies, expressly or implicitly, in reaching its verdict are considered by the district court and the appellate court de novo to determine whether those standards are correct as a matter of law."^[18] The court must insure that the correct legal standard or law is applied.^[19]

B. Invalidity Defenses

"Anticipation is a factual determination that is reviewed for substantial evidence when decided by a jury."^[20] A jury's verdict on obviousness is reviewed without deference on the conclusion of obviousness, which is a question of law, while "the underlying findings of fact, whether explicit or implicit within the verdict, [are reviewed] for substantial evidence."^[21] The standard of substantial evidence is applied to whether a specification complies with the written description requirement of 35 U.S.C. § 112, ¶ 1,^[22] Since enablement is a matter of law, the findings by the jury are reviewed without deference; however, the factual underpinnings of enablement are determined on the basis of substantial evidence.^[23]

A. Anticipation

At trial, EarthLink presented four anticipatory prior art references: (1) the VDM System; (2) the Bellcore RFI; (3) the Waring Article; and (4) the Ithell & Jones reference. Inline contends that there is no legally sufficient evidence for the jury to have found, by clear and convincing evidence, that any of those references anticipates the asserted claims.

Before discussing the individual prior art references, the court rejects an overarching argument by Inline that there is necessarily an insoluble inconsistency between the jury's finding of both invalidity and non-infringement. EarthLink presented five scenarios whether those verdicts could be reconciled. The court particularly agrees with EarthLink's third argument:

The jury could have accepted ... that the telephones were not part of the accused EarthLink ADSL system as a matter of fact and thus Inline did not prove that EarthLink was a direct infringer under 35 U.S.C. § 271(a) ... but also found that the prior art references disclose telephones (along with Mr. Waring's extensive testimony about telephones) and therefore disclose all the elements necessary to anticipate the claims in a single reference.

This argument is compelling, particularly in that it is one of the bases the court discusses, below, for upholding the jury's verdict of non-infringement.

1. The AT & T Voice Data multiplexer system (the "VDM System")

Inline presents two arguments as to why the VDM System does not anticipate as a matter of law. First, each of the asserted independent claims of the patents-in-suit^[24] requires either "a high frequency band of frequencies above the highest frequency of the telephone voice band," a "high frequency band," or a "high band of frequencies" (collectively, "the high frequency band limitation"). The court construed these terms to mean "[f]requencies above the telephone voice band between 0.25 MHZ [i.e., 250 kHz] and an undetermined upper limit."^[25] Inline contends there was no evidence presented at trial that the VDM System actually used frequencies above 250 kHz. Second, Inline argues that, in the VDM System, the data from the external source of information improperly passes through the telephone exchange.

Inline contends that there was no showing that the VDM System actually used frequencies above 250 kHz. Inline states that Arthur Williams^[26] and David Waring each testified that the VDM System did not transmit at the required frequency level. Williams testified that the VDM System used frequencies between 50 and 100 kHz,^[27] and Waring testified similarly.^[28] In light of that testimony, Inline contends that the VDM System lacks at least one express limitation of the asserted claims and, therefore, no reasonable jury could have concluded that the VDM system rendered the patents invalid.

EarthLink counters that the asserted claims are apparatus claims, rather than method claims, and none require actual transmission at or above 250 kHz. EarthLink contends that the asserted claims only require hardware capable of transmission above 250 kHz and that the evidence shows that the VDM System constitutes such hardware. EarthLink states that Williams testified that the VDM hardware presented to the jury and described in the printed publications is the same regardless of whether a user transmits above or below 250 kHz; that it is the very same "technology" for transmitting above or below 250 kHz; and that the choice of frequency merely corresponds to the value settings of some of the components.^[29] Williams also testified that the filters are exactly the same regardless of the frequency used for transmission.^[30] EarthLink also maintains that Williams confirmed that he actually tested the VDM System above 250 kHz with the same hardware.^[31]

EarthLink also contends that the record shows that the VDM System fully enabled the claimed invention; stating that Waring explained the relationship between frequency and distance (the higher the frequency the shorter the distance, and vice versa) was fully understood at least by the 1970s, such that one of ordinary skill immediately would have appreciated that the VDM System's hardware was fully capable of—and thus fully enabled to—transmit above 250 kHz based on well known and fully developed electrical engineering principles.^[32] EarthLink states that "[f]urther confirming this point, Williams in fact transmitted above 250kHz by simply adjusting the settings based on the well known correlation between frequency and distance."^[33] EarthLink concludes by stating that the "use of this existing circuitry confirmed what was well known in that art. Again, the `technology' was already present in the hardware; value setting simply had to be adjusted (just like choosing a volume setting)."^[34] EarthLink concludes that it was reasonable for the jury to "conclude from all of the evidence that the actual claims are fully anticipated by the VDM System because the evidence at trial was sufficient for the jury to conclude that this system contains the actual hardware and circuitry that satisfies each element of these system claims."^[35]

The court determines that substantial evidence was not presented that the actual hardware and circuitry of the prior art VDM System was, as constructed, capable of meeting the high frequency band limitation. First, trial record does not support EarthLink's contention that Williams actually tested the VDM System above 250 kHz with the same hardware. The court agrees with Inline that the corresponding testimony cited by EarthLink "merely establish[es] that Mr. Williams was aware of the inverse relationship between transmission distance and signal frequencies, and that he made measurements using wire spools to confirm this principle." Although Williams testified, for instance, that he would not have to change the low and high-pass filters of the VDM System in connection with higher frequency transmission, he testified that in order to transmit at the higher frequencies required by the claims-at-issue, he would have to change components of the VDM System (such as the values of resisters or capacitors in the unit), not just simply adjusting settings.^[36] The failure of the VDM System, as constructed, to be capable of transmitting at frequency-levels required by the high frequency band limitation means that the VDM System does not anticipate the claims-at-issue.^[37] The fact that replacing components might have an obvious solution which would have met that limitation is also not sufficient to demonstrate anticipation.^[38] Consequently, the court grants Inline's JMOL that the VDM System does not anticipate any of the claims-at-issue.

Inline also argues that each of the anticipatory references, including the VDM System, cannot invalidate the claims because signals from the "external source of information" flow to or through the "telephone exchange" in those references.^[39] The court construed "telephone exchange" as "a switching center for connecting and switching phone lines."^[40] Inline states that the court construed the phrase "signal interface," but does not quote the court's claim construction,^[41] rather, it discusses reasoning contained in the court's claim construction order concerning that term. With reference to that reasoning, Inline argues (for instance, with respect to the VDM reference) that a demonstrative exhibit illustrates T1 lines directly connected to the telephone exchange, the VDM system allows data signals on the T1 lines to flow back and reach the telephone exchange.^[42]

EarthLink argues strenuously that Inline is improperly making a new post-trial argument with its position that the claims do not allow any signals emanating from the "external source of information" to pass through the "telephone exchange" (i.e., the Central Office, or "CO"). EarthLink states that:

The price for this new argument is that there never should have been a trial in the first place. Industry standard ADSL in all instances passes Internet data through an ATM switch located in the CO (the accused "telephone exchange"); in other words, industry standard ADSL (including all instances of ADSL configured with DSLAMs in RTs) always passes signals emanating from the "external source of information" through the CO [on their way to the RT DSLAM and then on to the user's modem.]

EarthLink argues that no claim element explicitly prohibits "signals from the `external source of information' from flowing to or through the `the telephone exchange'"; that Inline never asked the court to construe (and the court did not construe) any claim element as prohibiting "signals from the `external source of information' from flowing to or through the `telephone exchange,'" and that Inline did not ask for (and did not receive) any jury instruction which would have captured this broad concept. EarthLink notes that, Inline's brief neither identifies exactly which claim terms it believes are missing from the anticipatory references, nor does Inline quote a phrase from any claim element, nor any claim construction provided by the court. Consequently, EarthLink maintains that Inline does not rely on anything that was actually presented to the jury or to the court.

EarthLink insists that the proper time and place for these arguments would have been during claim construction, not during JMOL practice. EarthLink concludes that since Inline's arguments were before the jury, and they were not part of the jury instructions, they have been waived.

EarthLink also states that Inline's position is inconsistent with positions it has taken throughout this litigation. In its most recent infringement contention interrogatory responses—well after the January 2004 Markman Order on which Inline now relies—Inline asserted that the claims would be met where a "DSL interface" is "connected to the external source of information, e.g., world wide web, Internet, data center, ATM cloud, etc."^[43] EarthLink states that Inline never modified its infringement contentions to reflect a prohibition that external source signals cannot flow through or to a Central Office. EarthLink further notes that Inline's invalidity expert, Beckmann, did not raise this argument in either of his two expert reports, on either of his two deposition days, or during either day of his trial testimony. Moreover, EarthLink contends that Inline's expert, Dr. Charles Jackson, admitted at trial that ADSL works in the very manner that Inline now says is prohibited, i.e., it sends Internet signals (data from the "external source of information") to and through the Central Office (the "telephone exchange"):

Q. Okay. Now, with the T1 line or with the fiber, the signal that is being sent out of the remote terminal is certainly above 250 kilohertz, isn't it?

A. Which signal?

Q. The signal that is carrying the Internet information. Stuff that came out of the DSLAM that is now heading back toward the central office, that is above 250 kilohertz; right?

A. Well, yes, it's light. The frequency associated with light, I can't remember what they are.

Q. Whatever it is, it's way above 250 kilohertz?

A. Sure.

Q. So the remote terminal is intentionally sending to the telephone exchange a signal above 250 kilohertz; correct?

A. Yes.^[44]

EarthLink also cites the summary judgment declaration of Albert Whited which confirmed that all RT DSLAMs pass Internet signals to and from the ATM switch in the CO, which then pass them to and from the Internet through the ATM network.^[45] EarthLink continues by noting that:

at no time prior to or during trial did Inline ever state, offer to stipulate, or explain to the court, the jury, or EarthLink that the claims prohibit the sending of Internet information from the RT DSLAM back through the telephone exchange (the CO) to the external source of information.

EarthLink concludes by stating that had it been aware of Inline's current argument, EarthLink would have analyzed it and might have modified its trial strategy to include, among other things, making obviousness contentions to overcome that argument.

Inline responds by repeating its argument based on the court's explanation in its claim construction order concerning the meaning of "signal interface." The court notes that significantly, however, the jury was not aware of the reasoning behind the constructions of claims terms provided to them. In arguing that EarthLink should not have been surprised by Inline's current position, it points to, inter alia, Inline's proposed claim constructions, and arguments by EarthLink during claim construction briefing and on summary judgment. The court is not persuaded by Inline's arguments and agrees with EarthLink that the present position set forth by Inline—that the court's claims construction order "necessarily precluded the external source's data signals from reaching the telephone exchange"—was not a theory appropriately presented at trial. Accordingly, the court declines to consider this argument by Inline in its JMOL motion with regard to any of the purportedly invalidating prior art.^[46]

2. The Bellcore RFI

Inline contends that EarthLink failed to satisfy its burden of proof that the Bellcore RFI anticipates all of the asserted claims because (1) EarthLink's expert, Waring, only a provided generalized and conclusory opinion; and (2) the reference fails to disclose key limitations of the claims. With regard to the specific limitations, Inline maintains that the Bellcore RFI does not disclose (a) the low-pass filter connected to the telephone in a splitterless configuration; (b) the RJ-11 jack in the configuration disclosed by claim 9 of the '585 patent; and (c) the specific low-pass filter required by claim 4 of the '585 patent.

Inline's first argument is that Waring failed to provide an element-by-element analysis of the Bellcore RFI and how each claim element was disclosed in that reference. Inline states that Waring only argued that, if the accused systems infringe, then the Bellcore RFI must anticipate the claims.^[47] In support of its argument that Waring failed to present clear and convincing evidence of anticipation, Inline cites the Federal Circuit's statement that:

Typically, testimony concerning anticipation must be testimony from one skilled in the art and must identify each claim element, state the witnesses' interpretation of the claim element, and explain in detail how each claim element is disclosed in the prior art reference. The testimony is insufficient if it is merely conclusory. General and conclusory testimony, such as that provided by Dr. Kazmer in this case, does not suffice as substantial evidence of invalidity. This is so even when the reference has been submitted into evidence before the jury.^[48]

Inline contends that Koito presents a factually analogous situation to this case. There, the defendant argued "that, if the jury found that Koito's lenses infringed, then the '268 patent was invalid because of anticipation by prior art taillight that used the same method as that used by Koito."^[49] The Koito jury returned a verdict of non-infringement and anticipation, as did the jury in this case. On appeal, the Federal Circuit "reject[ed] Koito's evidence of anticipation with respect to the prior art automobile lenses" and stated that "[b]ecause the jury found Koito's lenses to not infringe the '268 patent and also that the '268 patent was invalid, the only consistent way to interpret the jury's verdict is to determine that the jury did not find the prior art taillights to anticipate the '268 patent."^[50] The Federal Circuit also stated that "this court has made clear that there is no `practicing the prior art' defense to literal infringement."^[51]

Inline contends that in light of the similarity of the arguments and facts between this case and Koito, that decision compels a grant of JMOL of non-anticipation as to the Bellcore RFI.

EarthLink argues that Koito does not mandate "that the accused infringer must proffer an expert who mechanically matches every word in a claim with a specific word or disclosure in a prior art reference" and differentiates the evidence presented in this case from that considered in Koito. There, the Federal Circuit stated that "[b]ecause Koito merely entered the JP '082 reference into evidence and provided no specific testimony relating to it whatsoever, we hold that Koito did not present substantial evidence with respect to JP '082 to support the jury's finding of anticipation and obviousness."^[52] "Koito needed some explanatory testimony or other evidence to compare JP '082 with the patent at issue...."^[53]

EarthLink does not argue that Waring provided testimony identifying each claim element and how each element was disclosed in the Bellcore RFI, but contends that Koito does not require such element-by-element testimony. EarthLink notes that, in Koito, there was "no specific testimony... whatsoever" concerning the prior art reference, which was entered into evidence, and "not even mention[ed]" thereafter. Here, EarthLink states that there was significantly more than "some explanatory testimony or other evidence" concerning the Bellcore RFI. Specifically, that Waring's direct testimony concerning that reference spans a dozen pages of the trial transcript.^[54] Additionally, EarthLink argues that the jury could have concluded that Beckmann admitted that the Bellcore RFI anticipated the claims at issue with the exception of its purported failure to show distributed filtering with low pass filters.

Q. Now, do you agree with Mr. Waring that the Bellcore RFI anticipates all of the 11 claims that Inline asserts that EarthLink has infringed in this case?

A. No, I don't agree with that.

Q. Why not?

A. Two major factors are, first, the focus of this RFI is on what we have been calling the splitter ADSL architecture. And then, secondly, in my opinion, there is no identification, no disclosure of low pass filters being used separate from the transceiver unit.^[55]

EarthLink then cites testimony concerning those two issues which it frames as a dispute between the parties' experts concerning certain portions of the Bellcore RFI and that the jury evidently believed EarthLink's expert.

Finally, EarthLink argues the Koito has no application where the evidence shows that the prior art reference is materially identical to the accused device and states that "practicing the prior art" is available as an invalidity defense when the prior art and the accused technology are, in all pertinent respects, the same. EarthLink maintains that the Federal Circuit has repeatedly ruled that when the defendant alleges that the prior art is the same as the accused technology, the defendant need only prove that the prior art reference is materially identical to the accused device to prove invalidity. In support of that contention, EarthLink cites Evans Cooling Sys., Inc. v. Gen. Motors Corp.,^[56]Bennett Regulator Guards, Inc. v. Canadian Meter Co.,^[57]Vanmoor v. Wal-Mart Stores, Inc.,^[58] and Benedict v. Gen. Motors Corp.^[59]

Inline first responds that Koito is not limited to situations where explanatory testimony is completely absent, as suggested by EarthLink, and that other courts have not so limited that case.^[60] With respect to its argument that EarthLink is improperly presenting a "practicing the prior art" defense, Inline cites The Federal Circuit's statement in Tate Access Floors, Inc. v. Interface Architectural Resources, Inc. that:

[A]ccused infringers are not free to flout the requirement of proving invalidity by clear and convincing evidence by asserting a "practicing prior art" defense to literal infringement under the less stringent preponderance of the evidence standard.... [I]t is the presence of the prior art and its relationship to the claim language that matters for invalidity.^[61]

Inline also correctly points out that the cases cited by EarthLink (Evans Cooling, Bennett Regulator, Vanmoor, and Benedict) represent a situation distinct from the facts of this case: when there is no dispute that the accused infringing product was identical to the prior art.^[62] Those cases do not support EarthLink's position that they stand for the proposition that "when the defendant alleges that the prior art is the same as the accused technology, the defendant need only prove that the prior art reference is materially identical to the accused device to prove invalidity." There was no dispute in those cases that the accused product was identical to the prior art because the prior art was the products those plaintiffs accused of infringement.^[63]

Here, EarthLink's own accused ADSL system is not purported to be the anticipating reference. Rather, EarthLink presents prior art documents describing ADSL and contends that its ADSL system is "materially identical" and, thus, "if [EarthLink's] industry standard ADSL were found to infringe, then the patent claims that are at issue would have to be invalid because the Bellcore RFI describes industry standard ADSL."^[64] That testimony indicates that EarthLink is improperly relying on a "practicing the prior art" to establish invalidity where its ADSL system is not, itself, the prior art and Inline states that it "vigorously contends that the accused product is not the same as the prior art." Also, the court's review of Waring's testimony is not sufficient to show that he "identif[ied] each claim element, state[d][his] interpretation of the claim element, and explain [ed] in detail how each claim element is disclosed in the [Bellcore RFI]."^[65]

Consequently, the court grants Inline's JMOL that the Bellcore RFI does not anticipate the claims-at-issue.^[66]

3. The Waring Article

Inline contends that EarthLink argued in its closing that the Waring Article anticipates the asserted claims, but that EarthLink's own expert never offered an invalidity opinion about his own paper. Inline also argues that merely having the claimed elements present in a prior art reference is insufficient; rather, "these elements must be arranged as in the claim under review."^[67] Inline asserts that there was no such evidence from either side's expert. Inline also states that EarthLink never presented any testimony to "identify each claim element, state the witnesses' interpretation of the claim element, and explain in detail how each claim element is disclosed in the prior art reference," as required by precedent in Koito.^[68] Lastly, Inline contends that there was no evidence that the Waring Article discloses either a filter that "reflects substantially all of the energy in the high frequency band" or an RJ-11 jack connected between a filter and a branch network as required by claims 4 and 9 of the '585 patent, respectively.

EarthLink maintains that there is no requirement that it use its own expert to put this prior art reference into evidence. EarthLink states that in light of the admissions Beckmann made at his deposition, it made the strategic decision to present this paper through Inline's expert.^[69]

EarthLink states that the Waring Article was presented to the jury through the following Beckmann testimony:

Q. Okay. But you agree that the Waring paper disclosed an ADSL system; correct? That's what you told Mr. Lewis yesterday; correct?

A. Yes, that's correct.

Q. And the Waring paper specifically discusses the need for multiple low-pass filters if you have multiple phones; correct?

A. I believe that's correct; he has a discussion of that in a section of his paper.

Q. And you agree that the Waring paper discloses the fact that if you have multiple telephones you need to put multiple low-pass filters in front of each phone; correct?

A. I believe that's correct. If you could possibly pull up those two paragraphs in the paper, we can look at them; I can speak more confidently about what we are talking about.

Q. Okay. Do you recall telling Mr. Gaudet during your deposition that in fact you agreed with the fact that the Waring paper discloses the need to put low-pass filters in front of each telephone?

A. That seems reasonable. Again, I don't recall precisely what I said there.^[70]

EarthLink contends that, particularly when all inferences are resolved in its favor, Beckmann conceded that every limitation was present in the Waring Article.

Q. And, Dr. Beckmann, at this page, Mr. Waring discusses multiple low-pass filters. Do you see that in the second paragraph on this page?

A. Yes. I see where he is discussing use of small easily installed filters.

Q. Filters, plural?

A. Right.

Q. And you would agree that you interpreted this discussion that if he had multiple telephones or a consumer had multiple telephones you needed multiple low-pass filters; right?

A. I recall that discussion, I believe I indicated to Mr. Gaudet that I was just a little confused about the mention of multiple walled telephones in the kitchen, that created some confusion in my mind about where the plurality actually applied because people typically don't have multiple wall telephones in their kitchen, if you look across a lot of houses, and you can talk about multiple wall phones. So that confused me a little bit as to how to apply the S on filters, whether that's talking about filters in a single home or filters in multiple homes.

Q. But if you didn't have multiple wall telephones, if you just had an ordinary telephone sitting on the kitchen counter, you would put a filter in front of it; right?

A. I would certainly do that today. I was just trying to discuss this article as to what I could understand from the article.

Q. All right. Well, let's cut to the punch line, then. You agree with respect to the '446 patent that the Waring paper discloses all of Claim 1; right?

A. Again, I would have to say the Waring article mentions most, if not all, of the elements of the claim. I hesitate to use the word discloses since that seems to impart some special meaning in patent law that includes teaching or helping someone understand how to put the system together.

Q. You would agree that the Waring paper mentions every single claim limitation of Claim 1 of the '446 patent; is that correct?

A. I believe that that's correct. I believe that the '446 is the one that uses the conductive path term.

Q. And it has multiple telephones; right?

A. Right.

Q. And you did not offer an opinion during the course of your deposition with us that there was any claim element that was not mentioned in the Waring paper; right?

A. I believe that's correct.

Q. Okay.

A. Yes.

Q. And the same would be true with respect to Claim 1 of the '585 patent; right?

A. With respect to the Waring paper?

Q. Yes.

A. I believe it would also be the case that he mentioned—

Q. Every claim element in the '585 patent; right?

A. Right. I believe that's true.

Q. And he clearly mentioned every claim element of the '596; right?

A. Yes. Every claim element of the '596 is contained in the other.

Q. Fine. That's the easy one; right?

A. It's the one with fewer conditions; right.

Q. Right. And you have not offered any opinions that the Waring paper fails to disclose any of the additional elements that are found in the dependent claims of either the '446 or the '585 patent; right?

A. That's correct. I did not refer to the Waring paper as not disclosing any—not mentioning anything in the dependent claims."^[71]

EarthLink responds to Inline's statement that "EarthLink's own expert never offered and invalidity opinion about his own paper," as being irrelevant (since party admissions may suffice),^[72] and incorrect. Arguing that Waring's testimony was not necessary (in light of Beckmann's purported admissions), EarthLink nevertheless states that Waring offered the following testimony about the Waring Article:

Q. This is the article that you wrote in December of 1991?

A. Yes, it is.

Q. And as it says in the abstract, this paper provides an over view of the newly emerging asynchronous digital subscriber line. And this is a summary you wrote for a technical audience about the thinking at Bellcore about ADSL at that point, was it not?

A. Yes, it was for, an IEEE sponsored conference call.

Q. And it summarized the Bellcore thinking about ADSL at that point?

A. Yes, that is correct.

Q. And in fact, you called it, you referred [to it] as the first published paper on ADSL, haven't you?

A. I believe that to be the case, yes.

Q. Okay. And you put that in your resume, that it's the first published paper on ADSL?

A. Yes, I'm not aware of any earlier paper.

Q. And in your report in this case, this is the paper you argued had all the elements of the asserted claims just like Bellcore and Valenti?

A. My first expert report?

Q. Yes.

A. Yes.^[73]

EarthLink states that the other arguments made by Inline in its attempt to undo Beckmann's admissions were properly rejected by the jury.

In Nobelpharma, the case upon which EarthLink's argument primarily rests, the patent-at-issue was found to be invalid for failure to disclose the inventor's preferred mode of making the invention. The patent claimed "`an element intended for implantation into bone tissue'" and recited that the element "preferably ... [had] a network of particularly-sized and particularly spaced `micropits.'"^[74] The Federal Circuit stated that, "[f]or whatever reason," as part of the patentee's case-in-chief it introduced inventor testimony that:

(1) "there were some minor details that were not included [in the patent] and which proved to be quite important," (2) other skilled artisans would have to be "lucky" to obtain a suitable micropitted implant "by cutting a piece of titanium at a speed less than twenty meters per minute," the cutting speed disclosed in the patent, and (3) "any of the small detailed recipes that I discussed but did not specify" in the patent "can cause you to fail to get micropitting even though you were cutting the metal at less than twenty meters per minute."^[75]

The court noted that the record unambiguously indicated that when the inventor's patent application was filed, he was aware that "a variety of undisclosed machining parameters were critical to the production of a functional implant ... [and that the inventor] possessed a preferred mode of making the claimed implants" by the time the patent application was filed.^[76] "Thus, the evidence at trial leads to only one reasonable conclusion: [the inventor] possessed a preferred method of making the claimed invention and failed to disclose it sufficiently to enable those skilled in the art to practice that method."^[77]

The Nobelpharma court noted that "[n]ormally, evidence presented by a patentee-plaintiff will not support a grant of a JMOL invalidating a patent. That is because the burden is on an accused infringer to show by clear and convincing evidence facts supporting the conclusion that the patent is invalid."^[78] "[I]n unusual cases, an admission by a plaintiffs witness can be sufficient to support entry of a JMOL in favor of a defendant after the close of the plaintiff's case-in-chief, even where the defendant bears the burden of proof on the decided issue."^[79] The court determined that the trial court had not drawn adverse inferences against the plaintiff to support its judgment; it relied on inventor-statements "`that the jury would not be at liberty to disbelieve'" and "did not place the burden of proving validity on [the plaintiff as the plaintiff's] own evidence was clear and convincing that the patent is invalid."<sup>[80]</sup> Thus, the court concluded that Nobelpharma was "one of those `extreme' cases in which it was not improper to grant JMOL in favor of a defendant on an issue regarding which it bore the burden of proof."^[81]

Unlike Nobelpharma, this is not one of those "extreme" cases where EarthLink's reliance on testimony from the opposing party can sustain the jury's verdict on an issue it bore the burden of proof. In Nobelpharma, the evidence that the inventor did not disclose the best mode of practicing his invention was indisputable. Such is not the case here. Beckmann's testimony only recites his general agreement that certain hardware is "mentioned" in the Waring Paper. That testimony, however, does not provide clear and convincing evidence explaining how the hardware mentioned would demonstrate to one skilled in the art the connection between that article and the claims-at-issue. Moreover, Waring's general testimony concerning his authorship of the reference, is clearly insufficient to support the jury's verdict, even when combined with Beckmann's testimony and resolving all reasonable inferences in EarthLink's favor.

The court, therefore, grants Inline's JMOL motion that the Waring Article does not invalidate the claims-at issue.

4. The Ithell & Jones reference

With this reference, Inline repeats its Koito argument that EarthLink's expert failed to explain in detail how the Ithell & Jones article discloses each claimed limitation. Inline also argues that Waring's testimony failed to explain how the reference discloses the following elements of claim 61 of the '596 patent:

"circuitry for receiving a plurality of external signals ...";

"circuitry for transmitting to selected sets of one or more of the plurality of transceivers ..."; and

"a branch network which couples one of the plurality of telephone devices to the telephone exchange ..."

Inline makes the same argument with regard to the following limitations in claims 1-5 of the '446 patent:

"circuitry for receiving an external signal encoding an information stream from the external source of information"; and

"circuitry for transmitting over the telephone wiring network to the transceiver an internal signal in the high frequency band encoding the information stream."

With regard to claim 1 of the '585 patent, and its dependant claims, Inline states that Waring did not explain the disclosure of:

"a plurality of separate conductive paths, each coupling the signal interface and a different one of the plurality of transceivers ...";

"at each of the residences at which one of the transceivers is located, a branch conductive path coupled at a location separated from said transceiver ...";

"wherein each transceiver includes circuitry for communicating with the signal interface in a high frequency band of frequencies ...";

"circuitry for receiving a plurality of external signals encoding information streams from the external source of information..."; and

"circuitry for transmitting over the telephone wiring network to the transceivers a plurality of internal signals in the high frequency band ..."

Additionally, Inline argues that the Ithell & Jones article fails to disclose low-pass filters separate from the transceiver's location as required by all of the asserted independent claims. Lastly, Inline argues that Ithell & Jones cannot anticipate claim 9 of the '585 patent because of its failure to disclose either an RJ-11 jack or its "coupl[ing] between one of the branch conductive paths and filter connected to said branch." Inline also maintains that because the Ithell & Jones article does not disclose low-pass filters separate from the transceiver's location, it cannot anticipate any of the asserted claims. Finally, Inline maintains that EarthLink failed to present any evidence that the Ithell & Jones article disclosed either the RJ-11 jack or its "coupl[ing] between one of the branch conductive paths and filter connected to said branch," as required by claim 9 of the '585 patent.

As a general matter, rather than improperly relying on a "practicing the prior art" argument, Waring's testimony attempted to match the elements of the claims-at-issue with the disclosures of the Ithell & Jones reference.^[82] With regard to the "circuitry for receiving" claim elements, EarthLink contends that Waring explained in detail how figures 2 and 9 of the Ithell & Jones article discloses those elements by showing how multiple channels of data from an external source is multiplexed on an E1 line that is received by a signal interface placed in a cabinet.^[83] Concerning the "circuitry for transmitting" and "plurality of separate conductive paths..." claim elements, EarthLink states that Waring testified that, as reflected in figures 2 and 9 of the Ithell & Jones article, the signal interface would separate out the individual external data channels from the E1 line and would then place the data in a high frequency band above voice band on specific telephone lines leading out to the corresponding transceivers in the individual homes.^[84] With regard to the "branch network/branch path" claim elements, EarthLink states that Waring testified that, as shown in figures 2 and 9 and as reflected on page F5.5 of DX-14, the system proposed by Ithell & Jones would operate over the ordinary telephone network, reaching from the telephone exchange to the individual homes, and that the article provided for separate low-pass filters before every telephone device on every branch extension within a home.^[85] Finally, concerning the "circuitry for communicating" element, EarthLink states that Waring testified that the transceivers in the homes shown in figures 2 and 9 of the Ithell & Jones article had high-pass filters before them that would block voice-band signals, but would allow the transceivers to communicate with the signal interface in the cabinet in the high frequency band.^[86]

Ultimately, the court agrees with Inline that the record evidence cited by EarthLink opposing Inline's JMOL motion is insufficient to establish that all of the elements of the claims at issue are disclosed in the Ithell & Jones reference. At least with regard to the "circuitry for receiving" and "circuitry for transmitting" elements, required by all three patents, the testimony relied upon by EarthLink is either general testimony giving Waring's overview of the system described in the reference and not related to a particular claim and/or testimony not sufficiently on point for the particular claim element. Because the court determines that Waring's testimony was insufficient to "explain in detail how each claim element is disclosed in the [Ithell & Jones] reference,"^[87] that testimony cannot provide clear and convincing evidence of anticipation. In light of this determination, the court need not consider the parties' additional arguments directed at other purportedly missing elements from this reference.

Consequently, the court grants Inline's JMOL motion that the Ithell & Jones reference does not anticipate the claims-at-issue.

B. Obviousness

The jury instructions set forth only one basis for finding the asserted claims invalid for obviousness: the combination of the Bellcore RFI and the Valenti Article. Inline contends that the record does not contain substantial evidence that the combination of the Bellcore RFI and Valenti Article could invalidate the asserted claims.^[88] Moreover, Inline maintains that there was no testimony from EarthLink's expert on this combination. Although Waring gave testimony related to the Bellcore RFI and the Valenti Article, Inline insists that Waring did not offer testimony about what their combination would teach, or how the combination would disclose to a skilled artisan every limitation of the asserted claims. Consequently, Inline argues that the jury had no factual basis on which to conclude that any asserted claim was obvious to a person of ordinary skill in the art at the time of the invention. Having purportedly failed to present evidence on this issue, where EarthLink bore the burden of proof, Inline maintains that judgment as a matter of law in Inline's favor is compelled.

Additionally, Inline maintains that the evidence at trial establishes that the alleged combination of the Bellcore RFI and Valenti Article would not provide the necessary expectation of success for a finding of obviousness. Inline states that Beckmann's testimony on the issue was uncontroverted and precludes the obviousness finding as a matter of law.^[89] Moreover, Inline contends that although Waring discussed the Valenti article and the Bellcore RFI in relation to the accused ADSL system, it did not compare the references to, or show how they disclose, the asserted claims.

Lastly, Inline contends that Beckmann's testimony demonstrated that all secondary considerations (long-felt, but unmet, need; licensing of the patents; commercial success; and praise of the inventions) considered at trial compel a conclusion of nonobviousness. Inline maintains that EarthLink did not offer adequate evidence to rebut these secondary considerations and that those objective indicia, therefore, reinforce the evidence of nonobviousness.

Based on the above, Inline maintains that no reasonable jury could have found that EarthLink proved by clear and convincing evidence that any asserted claim is obvious in light of the combination of the Bellcore RFI and the Valenti Article and the court should grant JMOL on this issue.

EarthLink argues that Inline does not suggest that there are any missing or non-obvious claim elements and that, in light of the Supreme Court's decision in KSR Int'l Co. v. Teleflex, Inc.,^[90] and the Federal Circuit's decision in Leapfrog Enters., Inc. v. Fisher-Price, Inc.,^[91] the jury's decision on obviousness must stand. In response to Inline's argument that Waring did not testify about what the combination would teach, EarthLink cites Leapfrog and the Federal Circuit's caution against formulaic approaches to obviousness:

An obviousness determination is not the result of a rigid formula disassociated from the consideration of the facts of a case. Indeed, the common sense of those skilled in the art demonstrates why some combinations would have been obvious where others would not.^[92]

The court agrees with EarthLink that the evidence demonstrates that the Bellcore RFI and the Valenti Article should be combined. That evidence includes the testimony of both Beckmann and Waring that both references were written by the same author and both described ADSL: Waring described Valenti as an "elaboration" of the Bellcore RFI;^[93] Beckmann referred to the Valenti paper as an "expansion" of the Bellcore RFI.^[94]

The court determines, however, the record cannot support the jury's verdict on obviousness. Unlike its attempt to demonstrate, albeit unsuccessfully in the court's view, the presence of each of the specific claim elements in the Ithell & Jones article, the court again concludes that EarthLink did not carry its burden of showing by clear and convincing evidence that the two references, combined with the knowledge of one skilled in the art, disclosed each limitation of each claim at issue.^[95] The court previously determined, with regard to EarthLink's argument that the Bellcore RFI anticipates, that EarthLink is improperly relying on a "practicing the prior art" to establish invalidity where its accused ADSL system is not, itself, the prior art. As with the Bellcore RFI, Waring testified that the Valenti Article shows that if industry standard ADSL infringes, the patent claims must be invalid.^[96] Because the court determined that the cited testimony concerning the Bellcore RFI was insufficient to demonstrate an element-by-element disclosure of the asserted claims, Waring's additional testimony concerning the Valenti Article concerning claim elements purportedly missing from the Bellcore RFI cannot sustain the jury verdict on obviousness. Based on this determination, it is unnecessary to consider the parties' additional arguments concerning specific claim elements and testimony with regard to secondary considerations.

Consequently, the court grants Inline's motion for JMOL on the issue of obviousness.

C. Invalidity Under 35 U.S.C. § 112

1. Enablement

The enablement requirement set forth in 35 U.S.C. § 112, ¶ 1 provides, in pertinent part, that the specification shall describe "the manner and process of making and using [the invention], in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the [invention.]." It is a legal determination of whether a patent enables one skilled in the art to make and use the claimed invention. A specification is enabling even if some experimentation is required. Whether a specification is enabling is a question of law: however, "because a jury decided the issue here based on factual determinations," the court looks "to whether a reasonable jury could have made the underlying factual findings necessary to provide substantial evidence in support of its conclusion."^[97]

There is no requirement that:

a patent disclosure enable one of ordinary skill in the art to make and use a perfected, commercially viable embodiment absent a claim limitation to that effect. Title 35 requires only that the inventor enable one of skill in the art to make and use the full scope of the claimed invention.^[98]

Also, while the full scope of the claimed invention must be enabled, the specification "need not enable anything broader than the scope of the claims."^[99] "`[A]n enablement determination is made retrospectively, i.e., by looking back to the filing date of the patent application and determining whether undue experimentation would have been required to make and use the claimed invention at that time.'"^[100]

Prior to trial, the court issued an order precluding EarthLink's invalidity expert, Waring, from testifying on the issue of enablement.^[101] Consequently, EarthLink primarily relies on the trial testimony of Inline's inventor, Goodman, as demonstrating lack of enablement as a result of undue experimentation. Inline contends that there was no evidence presented at trial as to whether a hypothetical person of ordinary skill would have required undue experimentation to make the invention when the patent was filed. Further, Inline contends that the testimony relied upon by EarthLink is insufficient to support the jury's verdict that the claims were not enabled by the patent specification under the clear and convincing standard required for invalidity.

With regard to the asserted claims of the '596 and '446 patents, EarthLink avers that "[i]t took Mr. Goodman five years of work to build a system that practiced any of the asserted claims of [those patents]."^[102] Goodman's trial testimony does not support that assertion.

Q. At the time you filed your 1991 application, you had never built any system that actually practices the asserted claims of the '596 and '446 patent[s]; correct?

A. I think that's correct.

Q. And it was not until sometime in 1996 that you were able to actually build a system that practice the claim[s] of the '596 and '446 patents; is that correct?

A. Until 1996 I didn't have the funds to build a system to practice those patents.

Q. 1996 is the first time that you were able to build a system that practiced the claims of the patent[s]?

A. Yes.^[103]

With regard to the asserted claims of the '585 patent, EarthLink contends Goodman testified that "he was never able to build a system that practiced the asserted claims [of that patent]."^[104] In fact, Goodman's testimony was that he "never tried" to transmit signals from a transceiver or signal interface over the last thousand feet of telephone wire.

Q. "A[s] of the time that we took your deposition in this lawsuit, you still had never built a system that practiced the '585 claims; correct?

A. I think that's true, yes.

Q. And funds weren't an issue; correct? There was a period of time where funds weren't an issue?

A. Funds weren't an issue, but business profit was.

* * *

Q. [I]n connection with the 1991 patent specification that leads to the patents in suit here, the focus of the invention is really the transmission of signals from a transceiver or signal interface over the last thousand feet of telephone wire; correct?

A. That's the emphasis of the patent, if you call it focus; I guess that's fair, too, sure.

* * *

Q. [Y]ou stated in your patent specification that the transmission could occur over approximately the last thousand feet?

A. Right.

Q. That was just a theoretical projection at the time?

A That was a theoretical projection, yes.

Q. You had never been able to transmit distances ... of one thousand feet; right?

A. I never tried.^[105]

EarthLink cites Liebel-Flarsheim Co. v. Medrad, Inc.^[106] as support for its argument that Goodman's testimony was sufficient to support the jury's verdict on enablement. That case presented substantially different facts than here. In Liebel-Flarsheim, the Federal Circuit determined that the claimed invention covered both embodiments of a syringe with a pressure jacket and one without a pressure jacket.^[107] The court then examined the specification and found that it taught away from a syringe without a pressure jacket.^[108] The court next considered the testimonial evidence and found that it "support[ed] a conclusion that no genuine issue of material fact exists as to whether undue experimentation would have been required to make and use the injector without a pressure jacket."^[109] Here, there is no similar evidence from the specification or testimony to support the jury's verdict on enablement.

First, the court notes that there was no testimony concerning the amount of experimentation required to practice the claimed inventions of the '596 and '446 patents at the time of their filing. Second, contrary to EarthLink's assertion it took Goodman five years of work to build a system that practiced those claims, his testimony was that he did not have the funds to build such a system until 1996 and, when those funds were available, he built the claimed system that year. With regard to the asserted claims of the '585 patent, the court finds incorrect EarthLink's characterization of Goodman's testimony as establishing he was never able to build a system that practiced the asserted claims. Goodman testified that, although funds for building such a system were not an issue, business profits were. Also, rather than testifying that he had not been able to transmit distances of one thousand feet, Goodman stated that he "never tried."^[110] The court concludes, therefore, that Goodman's testimony does not support the jury's verdict on enablement.

EarthLink also contends that the jury could reasonably have concluded that the specification teaches away from the distances encompassed by the full scope of the claims.^[111] EarthLink argues that the full scope of the claims, "and that the claim scope (as seen by the accused system) cover[s] hardware and frequency levels that transmit[] over telephone wires for multiple thousands of feet."^[112] EarthLink concludes that the specification must enable a system that can transmit up to 16,000 feet.

EarthLink's assertion that the patents must enable a system that can transmit up to 16,000 feet because that is the distance over which the accused system operates is flatly contrary to a proper enablement analysis. "The dispositive question of enablement does not turn on whether the accused product is enabled. Rather, `[t]o be enabling, the specification of the patent must teach those skilled in the art how to make and use the full scope of the claimed invention without undue experimentation.'"^[113] More surprising to the court is that EarthLink's accused product based enablement argument was previously rejected by the court in its preclusion of Waring's enablement testimony recited in his expert report. In precluding Waring's enablement testimony, the court stated:

By requiring that the patent enable an end-to-end ADSL system, defendants ignore the rule that the specification "need not enable anything broader than the scope of the claims." This protects patentees from having someone avoid infringement merely by adding one additional element to an otherwise infringing product. This distinction is particularly important in the present matter because the accused system contains features that are not part of the claimed system, but which Waring contends must be enabled by the specification. For example, according to Waring, "ADSL is designed to operate over distances of up to approximately three miles [approx. 18,000 feet] and do so without any additional amplification mid-way along the transmission path." He concludes that 1,000 feet is the farthest distance discussed in the patent specifications, and therefore, the patents do not enable one of ordinary skill in the art to make an ADSL system which operates distances of 18,000 feet.

* * *

Thus, while defendants' ADSL service allegedly uses the claimed system to infringe, that does not mean that the patent specification must enable the ADSL service as opposed to merely the claimed system.^[114]

The court again rejects EarthLink's argument that the patents-in-suit must enable the accused product, and that the accused product embodies the full scope of the claims at issue.

The court finds that substantial evidence was not presented to support the jury's verdict of invalidity of the claims of the patents in suit based on lack of enablement and, therefore, grants Inline's JMOL motion on that issue.

2. Written Description

The jury returned a verdict that each of the claims at issue were invalid for failing to comply with the written description requirement of 35 U.S.C. § 112, ¶ 1 which requires a patent specification to contain an adequate written description. An adequate written description must "convey with reasonable clarity to those skilled in the art that, as of the filing date sought, [the applicant] was in possession of the invention. The invention is, for purposes of the `written description' inquiry, whatever is now claimed."^[115]

The purpose of the written description requirement is to prevent an applicant from later asserting that he invented that which he did not; the applicant for a patent is therefore required to recount his invention in such detail that his future claims can be determined to be encompassed within his original creation.^[116]

In reviewing a jury's findings on written description, the "court must accord deference to [those] findings [and] ... will not substitute its judgment for that of the fact finder."^[117]

Inline contends that EarthLink failed to present substantial evidence to sustain the verdict on this issue. In its opening brief, Inline contends that EarthLink sought to establish lack of adequate written description through the testimony of Waring, but that his testimony cannot be substantial evidence to sustain the verdict on this issue. Specifically, Inline notes, citing Moba, B.V. v. Diamond Automation, Inc.,^[118] that a written description analysis examines whether the inventor possessed the claimed invention, not whether he possessed or invented the accused technology. Accordingly, Inline maintains that Waring's testimony concerning whether inventor Goodman developed or was aware of ADSL is irrelevant to the proper inquiry, i.e., whether there is adequate description of a data transmission system that met the claim limitations, and not the particular system accused of infringement.

Next, Inline argues that Waring's criticism of the patents for not teaching enough about non-video embodiments is also irrelevant and incorrect, as the patents specifically describe transmitting signals and information in general. Inline insists that Waring merely provided conclusory testimony that the description in the patents was insufficient and, at best, was relevant only to enablement. Moreover, Jackson testified that a skilled artisan would have easily understood that disclosure of a type of "information," i.e., video signals, amply supported a claim to "information" in general and other types of signals including digital computer signals.

Finally, Inline contends that Waring's testimony regarding transmission distance^[119] again improperly focuses on the thousands of feet the accused ADSL systems transmit rather than the question of whether Goodman disclosed enough to demonstrate possession of the claimed invention. Inline maintains that, nevertheless, the '585 specification discusses feasible transmission of distances over 1000 feet and, therefore, demonstrates possession of the claimed invention.

EarthLink casts this question as one in which the jury was asked to decide between the expert opinions of Waring and Jackson, as two individuals of ordinary skill in the art. EarthLink contends that the record provides multiple independent bases to support Waring's opinion, and the jury's conclusion, that the written description requirement was not met. In support, EarthLink points to: (1) Waring's testimony that the patent contains no teachings about how to transmit digital data, and that the actual teachings of the specification were transmission of analog video over relatively short distances; (2) that the jury could reasonably have concluded that the specification taught away from distances significantly beyond 1,000 feet; (3) Waring's testimony about the differences in filtering between the frequencies used in the analog NTSC video transmission described in the specification versus what is required for ADSL; and (4) evidence concerning Goodman's actions and state of mind, in that Goodman had not heard of ADSL at the time he filed his 1991 application even though that technology was publicly known in 1991; and that Goodman purportedly did not envision that his invention could cover ADSL at that time.

Inline responds with the contention that EarthLink did not rebut any of the points raised by Inline in its opening brief; and maintains that the arguments raised by EarthLink in its opposition motion are insufficient to defeat its JMOL motion on the written description issue.

Analog versus Digital Transmissions

According to EarthLink, Waring explained that the patent had no teachings about how to transmit digital data^[120] and that the actual teachings of the specification were transmission of analog video over relatively short distances.^[121] Waring testified that the insertion of the word "computer" or an occasional use of the word "data" in the specifications cannot substitute for actual teachings of data solutions.^[122] Waring stated that the specification discloses the transmission of NTSC signals from one device to another, and that the occasional use of the word "data," "digital," or "computer" did not change his conclusion as one of ordinary skill in the art:

When I would bump into those words I would look at how it was used in context and look for elaboration and in particular I would look for teaching associated with it. I found very little teachings. In other words, the words may be used but there is not much description beyond that.^[123]

EarthLink contends that the specification's mere inclusion of words like "data," "digital," "computer," or "Ethernet" is the only thing Inline points to in attempting to overcome the jury's verdict on written description. Finally, EarthLink points to the following Waring testimony as specifically refuting Inline's arguments:

Q. What would be your opinion of somebody that read the specification that had an undergraduate degree in electrical engineering and two years of communication experience as to whether they would have reached the conclusion that the claims in this case were broad enough to cover an ADSL transmission system based on the written specification?

A. Well, based on the written specification, which is all about NTSC video signals over phone wiring in the home, I don't believe one of skill in the art would have come to the conclusion that the specification was about an ADSL system.

Q. Now, there has been some discussion between you and Mr. Lewis about digitizing video?

A. Yes.

Q. And when you read the patent specification, would one of skill in the art have been able to learn how to digitize video by reading the patent specification?

A. No.

Q. And he mentioned that the patent has, I don't know whether it was occasional or periodic, discussing references to the Ethernet?

A. Correct.

Q. When you received the patent specification, did you consider it to be describing to one of skill in the art basically how the builder uses an Ethernet?

A. It mentioned Ethernet in passing as an example of computer data. But that was about it. There was very little other additional discussion or teaching.

Q. Same question with respect to digital encoding?

A. Well, it just referenced the fact that video signals can be digitally encoded.

Q. Does it in fact teach someone to do the digital encoding?

A. No.^[124]

EarthLink contends that Inline relies on Jackson's testimony on this issue, but notes that this was a fact question and that, for the purposes of Inline's JMOL, the court must presume that the jury completely disregarded Jackson's testimony, leaving only Waring's testimony which it argues is sufficient to satisfy the JMOL standard.

Inline presents four reasons that EarthLink's "digital data vs. analog data" argument is without merit. First, Inline maintains that the argument is irrelevant because no claim limitation requires transmitting digital or analog signals, and that EarthLink did not cite any. Second, Inline maintains that EarthLink's argument regarding ADSL is a "red herring" because a non-infringement position "in the cloak of a validity challenge" is legally incapable of establishing a written description violation.^[125] Third, Inline states that EarthLink mistakenly argues that the words "computer," "data," or "Ethernet" cannot replace "actual teachings of data solutions." Inline reiterates that no claim element requires digital signal transmission and that EarthLink failed to respond to passages discussing signal/data transmission cited in its opening brief.^[126] Fourth, and finally, Inline insists that EarthLink's quotation of Waring's testimony again skirts the issue at hand. It states that the first third of the quotation addresses whether the patents disclose ADSL, allegedly recycling EarthLink's non-infringement position "in the cloak of a validity challenge."^[127] Inline states that Waring's remarks that the patents do not teach how to use or build digitized video, Ethernet, or digital encoding are relevant, if at all, to enablement; they have nothing to do with the claims (which require the transmission of only "signals") or the written description requirement, which focuses on possession of the claimed inventions, not their enablement.

The court agrees with Inline with regard to EarthLink's digital versus analog argument. The court notes first Inline's argument that no claim limitation requires transmitting digital or analog signals, and that EarthLink did not cite any. Moreover, Inline's opening brief clearly sets forth its contention that in considering whether there is an adequate written description, the focus on whether the inventor possessed the claimed invention, rather that whether he possessed or invented the accused technology. Much of the evidence cited by EarthLink, however, refers to whether the specification describes ADSL, e.g., the specification "do[esn't] teach anything about AD[SL], which is up to a three-mile phone line back to the central office"; "I don't believe one of skill in the art would have come to the conclusion that the specification was about an ADSL system"; and "I don't believe one of skill in the art would have come to the conclusion that the specification was about an ADSL system." Inline is also correct that other of Waring's testimony is related to enablement, rather than possession of the claimed inventions, e.g., whether the specification describes to one of skill in the art "how to digitize video"; "how the builder uses an Ethernet"; and whether it "teach[es] someone to do the digital encoding." Although EarthLink's evidence concerning ADSL may have been pertinent to its non-infringement defense, the court determines it is not substantial evidence to support the jury's verdict that the specification has inadequate written description of the claimed invention.

Distance

EarthLink contends that the jury could reasonably have concluded that the specification taught away from distances significantly beyond 1,000 feet and, therefore, the written description requirement is not met.^[128] Waring testified that the teachings in the patent related to hardware (transceivers and a signal interface) and frequency levels that could transmit over telephone wire for distances that were no more than several hundred feet, but that the claim scope covered hardware and frequency levels that transmitted over telephone wires for multiple thousands of feet.^[129] EarthLink contends that the specification describes 1,000 feet as the outer boundary of the claimed system and, therefore, the specification effectively teaches away from distances substantially in excess of 1,000 feet, a point EarthLink states that Goodman was forced to concede.^[130] EarthLink states that Beckmann admitted that "the transmission distances were mentioned up to 1,000 feet."^[131] EarthLink contends that this evidence supports the jury's verdict, because evidence that the specification teaches away from certain embodiments within the claim scope also supports a finding of lack of written description.

The court finds the evidence with regard to transmission distance cited by EarthLink as insufficient to support the jury's verdict on written description. The claims of the '585 patent requires "conductive paths exceed[ing] 1000 feet in length," but the testimony cited by EarthLink is directed primarily at whether the specification describes the multiple thousands of feet transmitted by the accused ADSL system. With regard to the requirement of the claims at issue, the court disagrees that Goodman conceded that 1000 feet was the outer boundary of the invention described in the specification. Goodman testified that the specification described "a system that goes beyond one thousand feet," and reiterated later in his testimony that he did not consider 1,000 feet to be the outer boundary described in the specification. Also, though Beckmann stated that "the transmission distances were mentioned up to 1,000 feet," he went on to testify that "given the techniques that were developed in this system, there is no reason whatsoever to think that those could not be distributed farther if the amount of data was similar to the amount of data that is carried, for example, over ADSL systems today."^[132] Furthermore, the specification also recites transmission distances exceeding 1,000 feet: noting attenuation is estimated to "occur[] before the lengths of extended pairs 405 reach 3000 feet";^[133] and stating that "connecting ten houses to a single transceiver/switch 400 may mean that some of extended pairs 405 will be longer than, perhaps, 1000 feet."^[134] For these reasons, the court rejects EarthLink's arguments concerning transmission distance as sufficient support for the jury's verdict on written description.

Filtering

EarthLink points to Waring's testimony concerning the differences in filtering between the frequencies used in the analog NTSC video transmission described in the specification versus what is required for ADSL.^[135] Earthlink contends that Goodman admitted that his patent did not describe any filters with the cut-off properties necessary for ADSL.^[136] EarthLink also states that Jackson acknowledged that the filtering necessary for ADSL was a challenging problem and that no filter in the specification was "up to the challenge" of filtering in the ADSL environment.^[137] EarthLink contends that this evidence also supports the jury's verdict.

Once again, EarthLink cites to evidence in support of its written description argument that has to do with whether the specifications describe the accused ADSL system, rather than whether the claims at issue are adequately described. The court again determines that such evidence is inadequate to support the jury's verdict on written description.

Goodman's Actions and State of Mind

EarthLink contends that evidence concerning Goodman's activities and motivations is highly relevant. First, EarthLink argues that Inline's patent counsel began drafting the claims of the patents-in-suit approximately 7 years after the date of the application.^[138] Goodman testified that he had not known about ADSL at the time he filed his 1991 application; that ADSL was publicly known at that time; and that he did not did not envision that his invention could cover ADSL at that time.^[139] EarthLink also contends that two years after learning about ADSL, in October 1993, Goodman argued to the ADSL standards body that splitterless ADSL could not work.^[140] EarthLink also states that Goodman admitted that he employed a "keep it alive" strategy to monitor industry developments so that he could draft claims to cover later developments.^[141] Finally, Goodman testified that when drafting the '585 patents claims targeting ADSL transmission, he relied on a book concerning digital subscriber line technology.^[142]

Citing Gentry Gallery, Inc. v. Berkline Corp.,^[143] EarthLink suggests that its proffered evidence concerning Goodman's activities and motivations is highly relevant to the written description issue. There, the Federal Circuit reversed a district court's judgment following a bench trial, and found a patent invalid for lack of written description based in part on an inventor's admission that he amended claims to cover the accused device after learning about the device in the market:

Finally, although not dispositive, because one can add claims to a pending application directed to adequately described subject matter, Sproule admitted at trial that he did not consider placing the controls outside the console until he became aware that some of Gentry's competitors were so locating the recliner controls.^[144]

EarthLink contends it is precisely for these circumstances that the "[a]dequate description of the invention guards against the inventor's overreaching by insisting that he recount his invention in such detail that his future claims can be determined to be encompassed with his original creation."^[145]

Although Goodman acknowledged he was not aware of ADSL until 1992, Inline points out that his testimony was that he was in possession of his invention since the filing of his original application.^[146] Inline is also correct that Goodman did not state that splitterless ADSL "would not work" in his submission to the ADSL standards body; rather, that submission set forth his opinion that splittered ADSL was better able to handle transmitting video to the phone "which was the application in 1993, was the only application."^[147]

Again, the written description requirement examines the claimed inventions, not the accused product, to which EarthLink's evidence concerning Goodman's actions and state of mind is directed. Moreover, even if Goodman's goal was to write claims which would cover ADSL, such practice is not per se improper.^[148] Moreover, EarthLink's reliance on Gentry Gallery is also unpersuasive. As the quote cited by EarthLink explicitly states, the fact that consideration of placing controls outside the console came after awareness of competitor's products was "not dispositive" but, rather, was additional evidence to support the determination that the written description requirement was not met in that case. There, the patent-in-suit contained broad claims for a sectional sofa wherein controls for a pair of parallel recliners were not limited to placement on a console between the recliners and narrower claims which did contain that limitation.^[149] The Federal Circuit held that the broader claims failed to satisfy the written description requirement because the written description clearly described the central console as the only location for the controls.^[150] Here, EarthLink focuses on evidence concerning the timing of Goodman's knowledge concerning ADSL and the drafting of his claims, rather than specifically focusing on particular claim elements purportedly not supported by the written description.^[151] The court determines, therefore, that EarthLink has failed to cite evidence which clearly and convincingly demonstrates that Goodman's actions and state of mind, separately or in combination with the other evidence cited in opposition to Inline's motion, supports the jury's verdict of invalidity for failure to comply with the written description requirement. Consequently, Inline's JMOL on that issue is granted.

D. Non-infringement

"Infringement is a question of fact, findings of which are accorded substantial deference on review."^[152] The jury found no infringement of any of the asserted claims. Inline contends that it made a prima facie infringement case by presenting testimony from various fact witnesses and by offering the testimony of its infringement expert, Jackson. According to Inline, Jackson testified about each limitation and stated how the accused systems met each element and concluded that EarthLink's splitterless ADSL system contain each of those limitations and, therefore, infringes. Inline states that EarthLink did not offer any witnesses—including an expert witness— to testify on non-infringement and that EarthLink relied entirely on its cross-examination of Jackson to show that EarthLink failed in its burden to establish infringement.

EarthLink contends Inline's motion for JMOL of non-infringement must be denied for at least two reasons: (1) the record allowed the jury to determine that Inline had not carried its burden with respect to infringement; and (2) the jury could have determined that the evidence showed that the telephones (a required element of every asserted claim) are not part of the accused EarthLink ADSL system.

In reviewing the evidence in the record while considering a JMOL motion, the court must draw all reasonable inferences in favor of the nonmoving party, and it may not make credibility determinations or weigh the evidence. Credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge. Thus, although the court should review the record as a whole, it must disregard all evidence favorable to the moving party that the jury is not required to believe. That is, the court should give credence to the evidence favoring the nonmovant as well as that evidence supporting the moving party that is uncontradicted and unimpeached, at least to the extent that that evidence comes from disinterested witnesses.^[153]

Burden on Infringement

EarthLink contends that Inline did not carry its burden on infringement. EarthLink first argues that because Jackson was Inline's paid expert (and its entire infringement case rested on his testimony), he was not a disinterested witness and the jury was free to disregard his testimony. Inline argues that an expert is not per se biased for receiving compensation for his services and notes that EarthLink did not cite precedent supporting such assertion. The court agrees with Inline's position that the fact that Jackson was a witness compensated by Inline, in and of itself, is insufficient reason for the jury to completely disregard his testimony.^[154]

EarthLink also argues that Jackson's testimony was heavily impeached during cross-examination and, therefore, the jury could have rejected his testimony because of that impeachment. Examples of this purported impeachment include: (1) testimony that the title of the ADSL industry standard regarding low-pass filters ("In-Line Filter for Use with Voiceband Terminal Equipment ...") was adopted as a result of Goodman's use of the term "Inline," the plaintiff corporation;^[155] (2) prior inconsistent statements from his declarations;^[156] (3) testimony concerning the phrase "destinations of information" contained in claim 1 of the '446 patent;^[157] (4) further inconsistent testimony about the frequency bands used between the central office and the remote terminal; the functionality of an industry standard DSLAM; and admissions the jury could have taken to support non-infringement positions;^[158] and (5) foundational testimony concerning conception of the idea that sparked ADSL in 1988-89 Earthlink characterizes as presenting Jackson in an unappealing light as a witness.^[159]

Not surprisingly, Inline argues that Earthlink mischaracterizes and distorts Jackson's testimony. The court, however, will not make determinations about the credibility of witnesses as such determinations are to be made by the jury. Furthermore, EarthLink points to the following portions of the jury instructions (to which EarthLink contends Inline did not object) concerning evidence and the consideration thereof, and credibility of witnesses, in general, and expert witnesses, in particular, as support for its position that the jury could reject Jackson's testimony.

1.5 Consideration of Evidence You should use your common sense in weighing the evidence.... Give it whatever weight you believe it deserves....

1.6 Direct and Circumstantial Evidence... Direct evidence is simply evidence like testimony of an eyewitness which if you believe it, directly proves a fact.... It is your job to decide how much weight to give direct and circumstantial evidence.... You should consider all the evidence, both direct and circumstantial, and give it whatever weight you believe it deserves.

* * *

1.8 Credibility of Witnesses In determining the weight given to the testimony of a witness, you should ask yourself whether there was evidence tending to prove that the witness testified falsely about some important fact.... Impeachment of a witness, whether a fact witness or an expert witness, occurs when his or her testimony is contradict by other evidence and can be considered when judging the credibility of that witness.

* * *

1.10 Expert Witnesses When knowledge of technical subject matter may be helpful to the jury, a person who has specialized training or experience in that technical field—called an expert witness—is permitted to state his or her opinion on those technical matters. However, you are not required to accept that opinion. As with any other witness, it is up to you to decide whether to rely upon them.

The court agrees with EarthLink that a reasonable jury could have determined that Jackson was impeached during his testimony and, therefore, lacked credibility. Based on such determination, the jury could reasonably have returned its non-infringement verdict. Consequently, Inline's motion for JMOL of infringement is denied.

"Use" of the Claimed Inventions

EarthLink's second argument against Inline's motion for JMOL of infringement is that it did not establish that EarthLink infringed the patents-in-suit under 35 U.S.C. § 271(a), which provides that "whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent therefor, infringes the patent." The claims of the patented invention require one or more telephones. Because EarthLink insists that ADSL neither requires nor uses telephones in any way, it does not "use" the patented invention.

On February 1, 2007, the court granted Inline's motion for summary judgement regarding use under 35 U.S.C. § 271(a) "to this extent: should Inline establish at trial that [EarthLink's] ADSL service infringe[s] the patents, [EarthLink] cannot avoid liability for infringement on the basis that [it] do[es] not use the patented inventions as defined under § 271(a)."^[160] According to Inline, that ruling rejected EarthLink's argument at summary judgment and again answers the question as to its JMOL motion. Secondarily, Inline maintains that the telephones are not part of the system for communicating information which is claimed and EarthLink is using. It asserts that the telephones recited in the claims merely indicate the positions of the filters and other elements of the system, so that the presence of telephones in the accused ADSL system is irrelevant.

In support of its argument, EarthLink contends that the evidence established that ADSL neither requires nor uses telephones; that other evidence demonstrated that telephones are an impediment to ADSL; and that there was more than sufficient evidence for the jury to find that the telephones were not part of EarthLink's ADSL system. In response to Inline's contention that the court's February 1, 2007 order precludes its current argument, EarthLink contends that its current non-infringement position was not addressed in that order.

EarthLink explains that under the court's order, if Inline had proven that the telephones were part of EarthLink's "ADSL system," EarthLink could not avoid infringement by saying it did not sell, own, or control that component. EarthLink contends that Inline did have to prove, however, that the telephones were part of EarthLink's ADSL services in the first place to "establish at trial that defendants' ADSL services infringe the patent." EarthLink states that Inline could not make EarthLink directly liable for infringing a claim element simply by choosing to arbitrarily label something as part of a "system." It argues that, if such were the case, then proof of direct infringement would be nothing more than an exercise in creative pleading (e.g., if the claim required a refrigerator in addition to everything else, EarthLink could not be liable for direct infringement based on the refrigerator in the user's home just because Inline decided to label the refrigerator as part of EarthLink's ADSL service.).

Earthlink contends that all of the evidence supported its position that the phones are not part of its ADSL service. EarthLink employee Greg Collins testified that the point of the low pass filters is to eliminate telephones from an ADSL, system.^[161] EarthLink executive Jim Anderson testified that, for purposes of DSL service, the customer does not need to have a telephone and that EarthLink does not provide telephones.^[162] Anderson also distinguished the accused ADSL service from the telephone service a telephone company may offer, and explained that EarthLink prefers if customers do not have telephones on the line with ADSL.^[163] Anderson further testified that ADSL is an access service, and is distinct from any service involving the use of a telephone.^[164] Earthlink maintains that Jackson's testimony supports its position that ADSL is an access service, which is distinct from any service involving the use of a telephone through his repeated references to instances in which people do not have telephone service but use the accused DSL.^[165]

EarthLink contends the above evidence supports the conclusion that telephones and telephone service are a separate service that is neither necessary nor desirable from the standpoint of ADSL provisioning, and that EarthLink's accused ADSL service has no connection to the telephone service at all. EarthLink notes that, in light of the court's February 1, 2007 order, it could not have made this argument with respect to components such as the DSLAM, which it acknowledges is used as part of ADSL services even though EarthLink does not own or control DSLAMs. In contrast to DSLAMs, Earthlink argues that the evidence showed that telephones are not part of EarthLink's "system," rather, that evidence established that the telephones are on the other side of the ADSL boundary point created by the low pas filters. Because this was a question of fact, EarthLink contends that the evidence was sufficient upon which the jury reasonably concluded the question in EarthLink's favor.

The court agrees with EarthLink's analysis of the court's February 1, 2007 order and is persuaded that, since at least one "telephone device" is an element of each of the asserted claims, the absence of evidence that EarthLink's ADSL system includes that element is substantial evidence upon which the jury could have returned its non-infringement verdict. For this additional reason, Inline's motion for JMOL of infringement is denied.

E. New Trial

Lastly, Inline request a new trial on all issues decided be the jury if the court declines to grant its JMOL motion. According to Inline, because the JMOL standard is higher than the standard for a new trial, the court should also grant Inline a new trial in the alternative for any issue on which the court grants JMOL. For any issue on which the court determines that substantial evidence supports the jury's verdict, Inline requests that the court independently review the record—including the issues discussed in the JMOL section of its briefs—and grant Inline a new trial because the jury verdicts are against the great weight of the evidence.

"The decision to grant or deny a new trial is committed to the sound discretion of the district court."^[166] "[W]here the ground for a new trial is that the jury's verdict was against the great weight of the evidence, the court should proceed cautiously, because such a ruling would necessarily substitute the court's judgment for that of the jury."^[167] In considering whether a new trial is warranted, "the court need not view the evidence in the light most favorable to the verdict winner. However, a new trial should only be granted where `a miscarriage of justice would result if the verdict were to stand,' the verdict `cries out to be overturned,' or where the verdict `shocks our conscience.'"^[168] Having reviewed the record, the court determines that the jury's verdict of noninfringement is not "contrary to the great weight of the evidence," or "wholly irrational," as Inline argues. Consequently, the court declines to exercise its discretion to order a new trial on that issue and denies Inline's motion.

V. CONCLUSION

For the reasons stated above, EarthLink's motion to file a sur-reply brief (D.I. 694) is granted. Inline's motion for JMOL on invalidity is granted and its motion for JMOL on infringement is denied (D.I.681). An appropriate order will issue concurrently with this motion.

ORDER

At Wilmington, Delaware, this 5th day of February, 2010.

For the reasons stated in this court's February 5th, 2010 Memorandum Opinion, IT IS ORDERED, ADJUDGED, AND DECREED THAT:

EarthLink, Inc.'s motion to file a surreply brief (D.I. 694) is GRANTED.

Plaintiff Inline Connection Corporation's, et al. motion for judgment as a matter of law, or in the alternative, for a new trial (D.I. 681) is GRANTED in part and DENIED in part.

1. Inline's motion for judgment as a matter of law on the invalidity issues is GRANTED.

2. Inline's motion for judgment as a matter of law on the infringement issue is DENIED.

3. Inline's motion for a new trial is DENIED.

NOTES

[1] Inline initially sued EarthLink. Since the original filing of the complaints, other plaintiffs were added because of their contractual relationships with Inline. For ease of reference all plaintiffs shall be referred to as "Inline" or "plaintiffs."

[2] Inline is a Virginia corporation with its principal place of business in Virginia.

[3] EarthLink is a Delaware corporation with its principal place of business in Georgia.

[4] In light of the court's modification of is claim construction of one of the disputed claim terms, Inline withdrew the 718 patent from the suit.

[5] The '596, '446, and the '585 patents are each continuations of a patent application filed July 14, 1989 that issued as U.S. Patent No. 5,010,399 ("the '399 patent") on Aril 23, 1991 and is not asserted in this action. More specifically, the '585 patent is a continuation of the application that resulted in the '446 patent, which is a continuation of the application that resulted in the '596 patent. The three patents share a substantially identical written disclosure.

Because the '596 line of patents each share a substantially identical written disclosure, citation to the '596 patent's written description ("common specification" or "the specification") in this opinion should be understood to refer to the same language in the written descriptions of the '446 patent and the '585 patent.

[6] See D.I. 664 (Jury Verdict). EarthLink argues that four items of prior art each anticipated the claims of the patents-in-suit. The jury's verdict sheet did not indicate which of those references the jury based its anticipation verdict on, nor did the verdict sheet as proposed by the parties request that indication.

[7] D.I. 681

[8] After briefing was completed on Inline's motion, EarthLink filed a motion to file a sur-reply brief "to correct the record as to certain mischaracterizations of the law and the trial record by Inline, and to ensure that the court has the proper context for resolving Inline's motion for judgment as a matter of law." D.I. 694. Inline did "not object in principle to the idea of a sur-reply brief," but contends that EarthLink's proposed sur-reply brief contains facts that purportedly need their own correction and requests the court to consider Inline's response to EarthLink's brief if it is considered. D.I. 695. In light of Inline's position, the court grant's EarthLink's motion and will consider both EarthLink's sur-reply brief and Inline's response thereto.

[37] See, e.g., Juicy Whip, Inc. v. Orange Bang, Inc., 292 F.3d 728, 738-40 (Fed.Cir.2002) (The Federal Circuit reversed the trial court's denial of JMOL motion on anticipation because, inter alia, "the record lacks substantial evidence regarding at least one limitation of asserted claim.... While the record contains testimony from several witnesses which, if believed by the jury, indicates that some of the claim limitations were found in the 1983 and 1988 dispensers, the record is devoid of evidence showing that the above [recited] limitations were found in either dispenser."); Key Pharmas. v. Hercon Labs. Corp., 161 F.3d 709, 718-19 (Fed.Cir.1998) (affirming trial court's determination that reference did not anticipate and rejecting argument that a particular example which delivered 2.0 mg/day "would merely have to be increased in size by 25 percent to deliver 2.5 mg/day ... [as] lack[ing] the kind of support in the record needed for proof of invalidity by clear and convincing evidence").

[38] See Connell v. Sears, Roebuck & Co., 722 F.2d 1542, 1548 (Fed.Cir.1983) ("The [trial court's] opinion says anticipation may be shown by less than `complete anticipation' if one of ordinary skill may in reliance on the prior art `complete the work required for the invention'", and that "it is sufficient for an anticipation `if the general aspects are the same and the differences in minor matters is only such as would suggest itself to one of ordinary skill in the art.'" Those statements relate to obviousness, not anticipation. Anticipation requires the presence in a single prior art disclosure of all elements of a claimed invention arranged as in the claim. "A prior art disclosure that `almost' meets that standard may render the claim invalid under § 103; it does not `anticipate.'") (citation omitted): see also Structural Rubber Prods. Co. v. Park Rubber Co., 749 F.2d 707, 716 (Fed.Cir.1984) (rejecting anticipation argument "that missing elements may be supplied by the knowledge of one skilled in the art or the disclosure of another reference" and stating that "Park's arguments can not substitute for the absence of evidence of an anticipatory reference").

[39] Inline presented arguments on this issue under both the court's construction and its own proposed constructions that the court rejected in its claim construction order. Inline presented its non-anticipation argument under its own proposed constructions, as well as under the court's constructions, to preserve all of its rights on appeal.

[40] Inline Connection Corp. v. AOL Time Warner Inc., 302 F.Supp.2d 307, 329 (D.Del. 2004).

[41] The court construed the "signal interface" as "a device interposed on the opposite end (i.e., the local side) of the public trunk line (as defined by the inventor in the patent) from the telephone exchange that performs the recited functions of the incorporated circuitry." Id.

[42] Inline makes similar arguments with respect to the Bellcore RFI ("the signals from the `external source of information' ... necessarily pass through (or to) the `telephone exchange'"); the Waring article ("the source's data signals reach the ADSL unit only by passing through and exchange's conventional telephonic switch"); and Ithell & Jones ("its system allows the signals from the `external source of information' to flow to or through the `telephone exchange'").

[44] D.I. 649 at 180:13-181:3 (Jackson cross). EarthLink responds to Inline's reply distinguishing Jackson's testimony as relating to light signals traveling along fiber optic cables by stating that "all parties agreed that, in ADSL, the `external source's data signal' (i.e., the Internet information) goes both `to and `through' the central office, regardless of whether it travels as a fiber optic light signal or as something else."

[45] EarthLink states that it cited Whited's report "to make plain that our expert and Dr. Jackson were in complete agreement that, in ADSL, the external data signals `pass to,' `pass through,' and `pass to and through' the `telephone exchange,' as `telephone exchange' had been construed for purposes of this case, and this agreement would have made infringement impossible under Inline's `data to or through' claim interpretation."

[46] See Bettes v. Stonewall Ins. Co., 480 F.2d 92, 94 (5th Cir.1973) ("[A] litigant cannot strategically lie behind the log until after the trial and receipt of evidence, argument, and charge to the jury before raising an issue not found in the pleadings nor included in the pre-trial order and then raise it when it is too late for his opponent to do anything about it. The manifest prejudice of such tactics would make a shambles of the efficacy of pre-trial orders and a fair trial."); Violette v. Smith & Nephew Dyonics, Inc., 62 F.3d 8, 10-11 (1st Cir.1995) ("Other than asserting federal preemption in its answer, Dyonics never mentioned it again either before or during the trial. It surfaced as an allegedly viable issue only after the jury returned its verdict.... Regardless of its potential applicability, and we express no opinion on the subject, Dyonics has waived the preemption issue by raising it substantively for the first time after trial.... In Sweeney [v. Westvaco Co., 926 F.2d 29, 36-41 (1st Cir.1991)], we held that the defendant waived its preemption defense by waiting to raise it until after the jury had returned an adverse verdict. Westvaco's failure to `alert the court to the problem' at any one of myriad opportunities prior to the jury verdict led us to decline to consider the defense."); see also Finnigan Corp. v. Int'l Trade Com'n, 180 F.3d 1354, 1363 (Fed.Cir. 1999) ("A party's argument should not be a moving target. The argument at the trial and appellate level should be consistent, thereby ensuring a clear presentation of the issue to be resolved, an adequate opportunity for response and evidentiary development by the opposing party, and a record reviewable by the appellate court that is properly crystallized around and responsive to the asserted argument."). The court also declines EarthLink's request for attorneys' fees based on this argument by Inline.

[47] D.I. 649 at 237:20-238:1 (Waring direct— "Q. And so the bottom line with respect to Defendant's Exhibit 6 is that if industry standard ADSL were found to infringe, then the patent claims that are at issue would have to be invalid because the Bellcore RFI describes industry standard ADSL. A. Right, I believe that is called `anticipation' in legal terms.") (emphasis added); see also it. at 236:11-237:19 (Waring direct—"A. you understand that Dr. Jackson has testified that industry standard ADSL infringes all 11 claims of the asserted patents? A. Yes, I understand that. Q. Okay. You're not here to offer opinions on infringement; right? A. No, I'm not. Q. Right. And we have another expert that is going to do that; is that right? A. Right. Q. At least, you think that is right? A. Yes, I believe. Q. And what we have done is we have asked you for purposes of your analysis is to assume that Dr. Jackson is right, industry standard ADSL meets the limitations of the claim. A. Right. When I did my analysis, I was asked to do a couple things. I was asked to use the Court's construction of the claim terms and I was also asked to assume that these infringement allegations are correct. Q. Okay. A. That's my starting point for my analysis. Q. Okay. And so if—I hope it doesn't happen but if the jury were to decide that in fact industry standard ADSL does infringe these claims, how does that impact your analysis with respect to invalidity based on the Bellcore RFI and the Valenti reference, Defendant's Exhibit 7? A. Since these documents represent what has become standard ADSL, and since these documents occur before Mr. Goodman'[s] patent in time, then these would invalidate the patent. Q. a you-can't-have-your-cake-and-eat-it-too type analysis? A. The way I see it is it is one way or the other.").

[62] Bennett, 184 Fed.Appx. at 978 n. 1 ("absent a dispute as to whether the complete Splash Guard device was involved in the anticipatory act") (emphasis added).

[63] In Evans Cooling, Evans filed suit alleging infringement by GM with its manufacture and sale of cars having GM's "LT1" engine and GM asserted invalidity because it had placed the patented invention on sale prior to the critical date of the patent-at-issue. 125 F.3d at 1450. Defendant was thus able to meet its burden of proving the LT1 engine embodied the patented invention by plaintiff's allegation that the LT1 engine infringed. Id. at 1451.

In Bennett, Bennet Regulator Guards, Inc. sued American Meter Co. alleging that its Splash Guard infringed the patent-in-suit. 184 Fed.Appx. at 997. Meter defended by contending that it already had developed and publicized the Splash Guard prior to Bennett's efforts to obtain a patent and that these acts invalidated the '029 patent by anticipation under 35 U.S.C. § 102(a) and (b). Id. Although the Federal Circuit determined that genuine issues of material fact and vacated the district court's grant of summary judgment, id. at 977, it "agree[d] with the district court `[w]hen the anticipatory reference is the accused product, the Defendant's burden [of showing that the anticipatory reference contains each and every claim element] is satisfied by the Plaintiffs infringement allegations in the Complaint that the accused product embodies the claimed invention.'" Id. at 978 n. 1 (second alteration in original).

In Vanmoor, the plaintiff sued Wal-Mart alleging infringement of its patent directed at a caulking gun cartridge. 201 F.3d at 1364. Wal-Mart argued that "certain of the accused caulking cartridges were identical to cartridges manufactured, sold, and used prior to the critical date for the '331 patent." Id. at 1365. The Federal Circuit stated that "[a]s was the case in Evans Cooling, the entire basis of the patent infringement claim is Vanmoor's (the patentee's) contention that the accused cartridges infringe the '331 patent." Id. at 1366 (emphasis added). "Although Wal-Mart ... bore the burden of proving that the cartridges that were the subject of the pre-critical date sales anticipated the '331 patent, that burden was satisfied by Vanmoor's allegation that the accused cartridges infringe the '331 patent." Id. (emphasis added).

In Benedict, the plaintiff's sued GM for infringement of his patent for an automated daytime running light system for cars and trucks. 184 F.Supp.2d at 1198-99. The court found that the record established that GM's automated daytime running light system was completed prior to the plaintiff's invention and, thus, GM, rather than plaintiff, was the first inventor of the system. Id. at 1199-1200. Citing Evans Cooling and Vanmoor, the court stated that those cases "establish that when a patent holder's entire claim is that an accused product infringes the patent, then, for purposes of determining on motion for summary judgment whether the patent is invalid because the accused product was earlier-invented or earlier-on-sale, no further showing of identity of the patented and accused products is required."

[66] In light of this determination, the court need not consider the parties' arguments directed at specific limitations purportedly missing from the Bellcore RFI. The court also determines the Beckmann testimony cited by EarthLink is not an admission, that all but two of the claims-at-issue specific elements are adequately disclosed in the Bellcore RFI and, in any event, does not establish by clear and convincing evidence the presence of those elements and did not relieve EarthLink of its burden to prove that the reference discloses them.

[95] The Leapfrog opinion, upon which EarthLink relies, demonstrates that in that case evidence of each of the limitations of the claim-at-issue was present in the two prior art references, with the exception of one element which was well known in the art at the time of the invention. See Leapfrog, 485 F.3d at 1160 ("Leapfrog argues that the district court engaged in improper hindsight in reaching its conclusion of obviousness by concluding that all of the limitations of the claim are found in the prior art.")

[108] Id. at 1379 (noting that the specification stated that a disposable syringe without a pressure jacket was "impractical" and that the specification provided "no guidance or suggestion of how to make or use a disposable syringe for high pressure use without a pressure jacket" and that each of the figures illustrated "a pressure jacket and all discussion of them refers to the pressure jacket").

[109] Id. at 1379 ("The inventors admitted that they tried unsuccessfully to produce a pressure-jacketless system and that producing such a system would have required more experimentation and testing. The inventors decided not to pursue such a system because it was `too risky.' The district court relied on various statements in the record by the inventors that testing of a syringe without a pressure jacket proved unsuccessful and that the inventors were not aware of any other similar testing being conducted at that time.") (emphasis added).

[110] The court notes that Goodman gave testimony indicating that no undue experimentation was needed to implement the one thousand foot feature of the '585 patent: See D.I. 644 at 259:8-15 (Goodman cross—"Q. Now, as of the time of your 1991 patent application, people knew how to transmit digital data for long distances over telephone wires; right? A. At certain data rates, yes. Q. And transmitting digital data for long distances over telephone wires, that could have well have been in excess of 1,000 feet right? A. Right.").

[111] See Liebel-Flarsheim, 481 F.3d at 1379 ("[W]here the specification teaches against a purported aspect of an invention, such a teaching `is itself evidence that at least a significant amount of experimentation would have been necessary to practice the claimed invention.'")

[120] D.I. 654 at 88:14-17 (Waring direct— "The patent specification, first of all, all the teachings are about analog video signals and none of them teach how one would transmit digital data over these very long phone lines.").

[121] D.I. 649 at 239:22-240:5 (Waring direct— "The specification is about a system for moving video over relatively short phone wires in the home maybe just outside the home and these are analog video signals such as a television channel. And, in fact, the specification talks a lot about things such are your remote control that you would use to change channels. It talks about VCRs and television sets. And the teachings in the specification are all consistent with that."); D.I. 654 at 112:9-12 (Waring cross "I think [Goodman] was still largely moving the analog NTSC signal from one point to another and it happened to have invented in it the closed-captioned data.

Have you taken that into account in your analysis? A. I have taken that into account in my analysis. There are these words in the specification. But I also have to look at what the teachings are that are associated with that, and whether that is elaborated upon in a way that one of skill in the art could understand it and comprehend it. Q. And at the end of the day, when you ... read the specification, your conclusion was that—A. My conclusion was that this taught the transmission of video signals, analog and TSC video signals over relatively short distances over a home. But they don't teach anything about AD[SL], which is up to a three-mile phone line back to the central office.").

[125] Moba, B.V. v. Diamond Automation, Inc., 325 F.3d 1306, 1321 (Fed.Cir.2003) (finding adequate written description and rejecting argument that the patent did not disclosed the accused apparatus because it "merely revives its non-infringement argument in the cloak of a validity challenge").

[126] Inline's opening brief listed the following passages from the common specification discussing signal/data transmission:

"The present invention relates to a system forsimultaneous two-way communication of video signals and other signals between ...." '596 patent, 1:22-25 (emphasis added).

"The communications systems disclosed in the parent and first and second CIP applications are designed to simultaneously transmit telephone signals and non-telephonic signals (such as cable television signals, other video signals, audio signals, data signals, and control signals) across the active telephone wiring.... The present invention adds to these techniques, providing distribution of all of these signals ...." '596 patent, 1:56-64 (emphasis added).

"This would enable subscribers to communicate video signals and other relatively wide bandwidth signals in the same way that they currently communicate voice signals." '596 patent, 3:9-11 (emphasis added).

"In this application, the technique for communications across a PBX is expanded to provide the same capabilities for wiring networks that provide the conductive paths of a computer local area network (LAN)." '596 patent, 7:30-34 (emphasis added). "The invention also provides two-way communications of signals of a general nature with the high capacity transmission line." '596 patent, 8:37-39 (emphasis added).

Inline also referenced Waring's testimony which acknowledged that the patent discusses data more broadly than merely video: "Q. Is it your impression that the specification of the patents talked about video and nothing else whatsoever? A. No. I think I said that there are references to things such as digital and local area networks, and so forth. There is mention—Q. There is reference to digital data? A. Yes, there is. Q. There is reference to computer data, is there not? A. Yes, there is." D.I. 654 at 109:19-110:2 (Waring cross).

[127] Moba, 325 F.3d at 1321.

[128] Only the claims of the '585 patent include a limitation referencing transmission of distances over 1,000 feet. Independent claim 1 of the '585 patent includes the limitation that "each of said separate conductive paths exceeds 1000 feet in length."

[132] The court notes Inline cites testimony from Goodman, Jackson, and Beckmann supporting its argument that a skilled artisan would understand that the video signals discussed in the patent require more bandwidth than other types of signals (such as computer data) and that, as a result, those other types of signals could reach father, to distances much greater than 1000 feet.

Okay. And I believe that you already testified that at the time you filed this 1991 application, you did not envision that this patent specification covered ADSL; is that correct? A.

[147] D.I. 644 at 250:14-254:19 (Goodman cross—agreeing that his submission opined it was "better ... having the transceiver and the modem at the side of the house as opposed to at the internal jack"; that one of the "drawbacks with having the transceiver on the internal wiring" was "that an extremely sharp expensive and presumably unwieldy low-pass filter must be applied to every telephone device to prevent the higher harmonics"; and that in his "submission you are expressly criticizing the system for ADSL as implemented today; is that correct? A. No. I'm criticizing the use of splitterless ADSL for transmitting video to the phone, which was the application in 1993, was the only application"; and where low-pass filters are put in the house, that "arrangement is sure to degrade reception of the downstream ADSL signal, significantly constricting the distance/bitrate tradeoff curve. This stands in direct conflict with the spirit of ADSL, which is to realize the maximum possible bitrate across the external wires.") (emphasis added). Though Goodman's 1993 submission clearly criticized splitterless ADSL, that submission did not state such configuration "would not work."
