MEMORANDUM AND ORDER RE: PROSECUTION LACHES
SHUBB, District Judge.
In a separate order, the court has determined that Genentech's product, Herception *1140 infringes Chiron's patent on monoclonal antibodies that bind to the HER2 human breast cancer antigen. Chiron now moves for summary judgment on Genentech's prosecution laches defense.
I. Factual Background
The patent at issue, U.S. Patent No. 6,054,561 ("'561 patent"), is one of several Chiron[1] patents that date back to two patent applications filed in 1984 and 1985. The first patent that Chiron received based on the 1984 and 1985 applications, U.S. Patent No. 4,753,894 ("'894 Patent"), issued in 1988. The '894 patent claims "murine monoclonal antibod[ies]" that bind to human breast cancer, and has an expiration date of June 28, 2005. ('894 Patent.)
The same year that Chiron was issued the '894 patent, it filed a continuation application that ultimately issued as U.S. Patent No. 5,169,774 ("'774 Patent"). The '774 patent, which issued in 1992, claims "monoclonal antibodfies]" that "bind to a common monomelic 210kD protein present in cancerous breast tissue." The expiration date of the '774 patent is also June 28, 2005. ('774 Patent.)
In 1994, Chiron filed another continuation application which led to the issuance of U.S. Patent No. 5,629,197 ("'197 Patent") in 1997, which claims, among other things, monoclonal antibodies "produced by a hybridoma." ('197 Patent.)
In 1995, Chiron filed yet another continuation application, which was amended in 1999 to set forth broad claims to monoclonal antibodies that bind to HER2. The Patent Office accepted these amendments, and on April 25, 2000 issued the '561 patent to Chiron. The '561 patent is subject to a "terminal disclaimer", which means that the '561 patent adopts the June 28 2005 expiration date of the '894 and '774 patents, thereby "disclaiming" any portion of the term of the patent monopoly that would have extended beyond that date. ('561 Patent; Riley Decl. Ex. 22 at 1-2.) Chiron contends that the '561 patent is entitled to rely on the patent applications filed in 1984 and 1985 for priority.
While Chiron was prosecuting these various patent applications, Genentech committed substantial resources to the research and development of anti-breast cancer antibodies. In the late 1980s, Genentech identified a murine (mouse) monoclonal antibody, 4D5, that binds to HER2 and is capable of reducing tumor growth and cell division. (See Riley Decl. Ex. 10.) In December of 1990, Genentech submitted an application to the FDA to conduct clinical trials using 4D5. (Id.) Several months later, Chiron contacted Genentech, asserting that Genentech's antibody infringed the '894 patent. (Id. Ex. 13, 14.) Genentech declined to license Chiron's technology.
By 1992, Genentech had successfully "humanized" an anti-HER2 antibody by combining genetic sequences modeled after murine antibodies with human DNA sequences. (See Id. Ex. 15.) Genentech applied to the FDA and received approval to conduct clinical trials of its humanized antibody. (Id.) From June of 1995 through January of 1996, representatives of Chiron and Genentech engaged in negotiations regarding a number of patents and products, including Chiron's anti-HER2 antibodies and patent?. (Id. Ex. 2; Celio Opp'n Decl. Ex. W.) In connection with these negotiations, Genentech obtained opinion letters from outside counsel concluding that the '894 and '774 patents were *1141 invalid and not infringed. (Riley Decl. Ex. 13, 17, 18.) Genentech did not take a license from Chiron at that time. In 1998, Chiron and Genentech engaged in further discussions regarding the '894 and '774 patents, and the result of those discussions was the same. (Id. Ex. 19; Celio Opp'n Decl. Ex. W.)
When the '561 patent issued to Chiron on April 25, 2000, Chiron contacted Genentech and asserted that Herceptin infringed its patent rights. Genentech received an opinion from counsel that the '561 patent was invalid and not infringed, and declined to license the patent from Chiron. (Riley Decl. Ex. 20, 23.)
II. Discussion
The court must grant summary judgment to a moving party "if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(c). The party adverse to a motion for summary judgment may not simply deny generally the pleadings of the movant; the adverse party must designate "specific facts showing that there is a genuine issue for trial." Fed.R.Civ.P. 56(e); see Celotex Corp. v. Catrett, 477 U.S. 317, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). Simply put, "a summary judgment motion cannot be defeated by relying solely on conclusory allegations unsupported by factual data." Taylor v. List, 880 F.2d 1040, 1045 (9th Cir.1989). The non-moving party must show more than a mere "metaphysical doubt" as to the material facts. Matsushita Elec. Indus. Co. v. Zenith Radio, 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986).
Prosecution laches is an equitable doctrine that "may be applied to bar enforcement of patent claims that issued after an unreasonable and unexplained delay in prosecution even though the applicant complied with pertinent statutes and rules." Symbol Techs., Inc. v. Lemelson Med., 277 F.3d 1361, 1362 (Fed.Cir.2002). Until the Federal Circuit's decision in Symbol Technologies, Inc. v. Lemelson Medical earlier this year, there had been some confusion as to whether prosecution laches was a viable defense. 277 F.3d 1361. Symbol Technologies affirmed the validity of the defense, but did not articulate a test for when the defense is established.
The court, however, is not without guidance as to what must be shown before the prosecution laches doctrine will bar the enforcement of an otherwise valid patent. The traditional laches defense, which targets a patentee's unreasonable delay in bringing a lawsuit for infringement, is well understood and offers some general principles that are useful here. Traditional laches requires (1) unreasonable and unexcusable delay by the patentee; and (2) material prejudice to the alleged infringer attributable to the delay. AC. Aukerman v. R.L. Chaides Construction Co.. 960 F.2d 1020 (Fed.Cir.1992). Pending further elaboration by the Federal Circuit, the court will apply this test to the facts of this case.[2]
Chiron argues that it is entitled to summary judgment on Genentech's prosecution laches defense because (1) the prosecution laches defense does not apply where, as here, the patent is subject to a terminal disclaimer; and (2) even if it does, Genentech cannot show that it was materially prejudiced as a result of Chiron's delay in prosecuting the '561 patent.
*1142 A. Terminal Disclaimer
A patent is often described as a quid pro quo between the patentee and the public. Pfaffv. Wells Elecs., Inc., 525 U.S. 55, 63, 119 S.Ct. 304, 142 L.Ed.2d 261 (1998). In exchange for a limited monopoly over the intellectual property in a patent, the patentee must tell the public what his invention is and how to use it. When a patentee delays in prosecuting his patent, he extends the monopoly over his invention and deprives the public of its use. See Woodbridge v. United States, 263 U.S. 50, 58-59, 44 S.Ct. 45, 68 L.Ed. 159 (1923).
Chiron argues that the prosecution laches defense is exclusively targeted at preventing inventors from unfairly extending the terms of their patent monopolies in this way. According to Chiron, the defense is not implicated when an inventor files a "terminal disclaimer," which limits the term of a patent's monopoly so that it will expire on the date that an earlier issued patent is set to expire. By definition, a terminal disclaimer does not extend the term of an inventor's monopoly.
Chiron asks the court to read the law on prosecution laches too narrowly. In addition to addressing the concern over patentees extending the terms of their patent monopolies, the prosecution laches defense also responds to concerns that inventors will file narrow claims, await intervening developments, and then file broader claims to cover those developments.
Woodbridge v. United States, the case referred to in Symbol Technologies as the origin of the prosecution laches defense, expresses these dual concerns. 263 U.S. 50, 44 S.Ct. 45, 68 L.Ed. 159. In Woodbridge, the patentee filed an application for a type of rifle ammunition in 1852, and then "sat down and waited until after the Civil War came on in 1861 before seeking to avail himself of the patent." The Court held that the patent was unenforceable because the inventor's "deliberate and unlawful purpose to postpone the term of the patent the inventor had always intended to secure" had "deprived the public of a decade of free use of the; patent." Id. at 59, 55, 44 S.Ct. 45. The court was also concerned with the fact that while the inventor delayed, other inventors had filed applications and made advances in the art that the inventor later tried to cover by applying for changes in the specification and claims of the patent. Id. at 57, 44 S.Ct. 45. Accordingly, the Court found that the inventor had forfeited his rights to his patent. Id.
The next Supreme Court case to address the issue, Webster Elec. v. Splitdorf Elec. Co., 264 U.S. 463, 44 S.Ct. 342, 68 L.Ed. 792 (1924), relied on similar reasoning to hold a patent that issued after an eight year delay unenforceable. As Chiron points out, Webster emphasized that a patent should not be enforced where it would result in "an undue extension of the patent monopoly against private and public rights." Id. at 466, 44 S.Ct. 342. However, Webster was equally concerned that the inventor in that case "simply stood by and awaited developments" before seeking broad claims that he could have filed with the initial patent application. Id. at 466, 44 S.Ct. 342. Because the broader claims of the patent were added after a long delay as "an exigent afterthought, rather than a logical development of the original application," the patentee lost whatever rights it might otherwise have been entitled to. Id.
Cases following Woodbridge and Webster have picked up on both rationales for the prosecution laches defense. See Wirebounds Patents Co. v. Saranac Automatic Mack Corp., 65 F.2d 904, 906 (6th Cir. 1933) (expressing concern both over inventor's attempt to extend the terms of patent monopoly and the inventor's assertion of broad claims that the inventor could have asserted earlier, the sole purpose of which *1143 was to cover what had been issued to others); Progressive Games, Inc. v. Amusements Extra, Inc., 83 F.Supp.2d 1180, 1183 (D.Colo.1999) (same).
The Federal Circuit may have taken a step back from the second rationale for the prosecution laches defense, however. In Kingsdown Med. Considtants v. Hollister, Inc., 863 F.2d 867, 874 (Fed.Cir.1988), the Federal Circuit held that "there is nothing improper, illegal, or inequitable in filing a patent application for the purpose of obtaining a right to exclude a known competitor's product from the market." Id.; see also Multiform Desiccants, Inc. v. Medzam, Ltd., 133 F.3d 1473 (Fed.Cir.1998). Although Kingsdown was not a prosecution laches case, it concerned another equitable defenseinequitable conductand therefore its discussion of what is and is not equitable behavior by patentees is relevant to this case.
However, Kingsdown did not address the question of how a long period of delay affects the equities of the situation, particularly where the patentee could have earlier asserted broad claims that would have covered the competitor's product. Where a long period of delay is involved, other inventors may work under the assumption that the patentee is not going to prosecute broader claims; they may develop improvements only to find that they are infringers of a later-prosecuted patent. Kingsdown therefore does not preclude an alleged infringer from asserting these kind of circumstances as grounds for a prosecution laches defense.
Moreover, a bright line rule that the prosecution laches defense never applies when a terminal disclaimer has been filed would run contrary to the principle that "with its origin in equity, a determination of laches is not made upon the application of mechanical rules." A.C. Aukerman, 960 F.2d at 1032; see also Cruz v. Melecio, 204 F.3d 14, 23 (1st Cir.2000) (holding that a court in sitting in equity should "assess the totality of the circumstances and customtailor appropriate relief). While it certainly is appropriate to weigh the filing of a terminal disclaimer as an equitable consideration, and while it may weigh strongly in favor of finding the delay is reasonable, there is no suggestion in the case law that the filing of a terminal disclaimer necessarily and in every case disposes of the defense. Moreover, the court is reluctant to pronounce a bright line rule when the Federal Circuit has yet to fully articulate the metes and bounds of the prosecution laches defense. Therefore, the court turns to the merits of the defense.
B. Unreasonable Delay
Chiron's '561 patent issued more than fifteen years after the first parent application was filed. Chiron has not proferred any reason for this delay, or argued that it was unintentional. Rather, as discussed above, Chiron contends that the delay is not unreasonable because the terminal disclaimer does not extend the term of the patent monopoly. Although the filing of the terminal disclaimer weighs heavily in favor of finding that the delay was not unreasonable, there is sufficient evidence in the record to support an inference in Genentech's favor that the delay was unreasonable.
Chiron has taken the position that the '561 patent is entitled to rely on the 1984 and 1985 applications for priority. For this to be true, the 1984/1985 applications must support the broad claims of the '561 patent. Thus, if Chiron is correct about the priority date (an issue that will be resolved at trial), then Chiron could have filed broad claims to monoclonal antibodies as early as 1984. See Woodbridge, 263 U.S. at 57, 44 S.Ct. 45 ("In this case we have a delay of nine years and a half in securing a patent that might have been had at any time in that period for the *1144 asking ... This is a case of forfeiting the right to a patent by designed delay.")
Genentech acknowledges that the 1984 and 1985 applications contain broad claims to "functional equivalents" of murine monoclonal antibodies, and that in prosecuting the '894 patent, Chiron tried to obtain those claims. However, Genentech points out that the '894 patent issued in 1988 with claims only to "murine monoclonal antibodies]." ('894 Patent, emphasis added.) Thus, Genentech argues that no later than the date of the '894 patent, "Chiron was aware that it had not been granted claims to non-murine anti-HER2 antibodies. At that point, it was incumbent upon Chiron to begin seeking those claims." (Genentech Opp'n at 11.)
The prosecution history reflects that the same year the '894 patent issued, Chiron submitted another patent application with claims to "monoclonal antibodies." In 1992, the '774 patent issued on this application without the "murine" modifier in the claims of the patent. Two years later, Chiron filed a file wrapper continuation of the earlier applications. The 1994 application issued as the '197 patent in 1997. In 1995, Chiron filed another continuation application for a patent on nucleic acid molecules. After substantial back and forth with the PTO Chiron filed amendments to this application in 1999, and the '561 patent issued the next year.
While Chiron appears to have repeatedly sought to expand the scope of its claims throughout the prosecution history of the patent, there are still unexplained periods of delay between the various patent applications. Genentech argues that the reason for Chiron's delay was that it was waiting for Genentech or some other company to develop a lucrative product so that it could craft broader claims designed specifically to cover that product, and Chiron has not offered an alternative explanation. Although the terminal disclaimer weighs in Chiron's favor, the court must draw all reasonable inferences in Genentech's favor in ruling on this motion. Therefore, the court cannot say that as a matter of law, Chiron's delay was not unreasonable.
C. Prejudice
Chiron argues that in any case, Genentech cannot demonstrate prejudice as a matter of law. To receive the benefit of a laches defense, Genentech must show not only that it was prejudiced, but also that there is a nexus between Chiron's delay in prosecuting the '561 patent claims and the alleged prejudice. Hemstreet v. Computer Entry Sys. Corp., 972 F.2d 1290, 1294 (Fed.Cir.1992). Genentech argues that Chiron's delay in this case was both presumptively and actually prejudicial.
1. Presumption of Laches
In a traditional laches case, a presumption of laches will arise where the patentee delays bringing a lawsuit for six years or more after the date the patentee knew or should have known of the alleged infringing activity. A.C. Aukerman, 960 F.2d at 1038. Once the presumption arises, the patentee may offer proof directed toward rebutting the laches factors. Id. at 1037. "Such evidence may be directed to showing either that the patentee's delay was reasonable or that the defendant suffered no prejudice or both. By raising a genuine issue respecting either factual element of a laches defense, the presumption of laches is overcome." Id. (citations omitted) (emphasis added).
Even if this presumption applies in a prosecution laches defense, and even if the delay in question here exceeded six years,[3]*1145 Chiron has submitted evidence to rebut the presumption. As discussed above, the filing of a terminal disclaimer raises a "genuine issue" respecting the reasonableness of Chiron's delay. Because a patentee may overcome the presumption by raising a genuine issue on one of the laches factors, no presumption of laches applies here.
2. Actual Prejudice
A plaintiff's delay may result in both evidentiary and economic prejudice to the defendant. Genentech does not allege that it suffered evidentiary prejudice as a result of Chiron's delay, but contends that it suffered economic prejudice. Economic prejudice may arise where the defendant will suffer the loss of monetary investments or incur damages which likely would have been prevented had it not been for the plaintiffs delay. Aukerman, 960 F.2d at 1033. The change in the defendant's economic position "must be because of and as a result of the delay, not simply a business decision to capitalize on a market opportunity." Gasser Chair Co. v. Infanti Chair Mfg. Corp., 60 F.3d 770, 774 (Fed. Cir. 1995). Damages attributable to a finding of liability do not constitute economic prejudice, because then economic prejudice would arise in every suit. Aukerman, 960 F.2d at 1033. However, "this does not mean that a patentee may intentionally lie silently in wait watching damages escalate, particularly where an infringer, if he had had notice, could have switched to a noninfringing product." Id. (citations omitted).
Genentech alleges that had Chiron prosecuted the patent earlier (1) it would not have been "trapped" into an "exorbitant royalty rate" by Chiron; and (2) Genentech could have designed around the patent and therefore avoided infringement.[4]
a. Royalties
Genentech's argument that Chiron delayed prosecution of the '561 patent in order to "trap" Genentech into a high royalty rate is based on testimony by Chiron's damages experts that in general, the later in drug development a licensing deal is struck, the higher the royalty rate will be. (Edwards Report ¶ 19; Leitzinger Report ¶ 18; Leitzinger Dep. at 81-82.) Genentech contends that by waiting until Herceptin was in a late stage of product development to prosecute the '561 patent, Chiron was able to demand a higher royalty rate in licensing negotiations with Genentech once the patent issued. The purported prejudice to Genentech, therefore, appears to be that had Chiron obtained the '561 patent earlier, Genentech could have taken a license on the patent at a low royalty rate and avoided both the cost of litigation and the possibility of a high damage award.
Chiron argues that court ordered royalty payments and litigation costs are damages *1146 that are "attributable to a finding of liability," and therefore cannot as a matter of law support a finding of economic prejudice. See Aukerman, 960 F.2d at 1033. However, the Federal Circuit has emphasized that "a patentee may [not] intentionally lie silently in wait watching damages escalate," which is essentially the substance of Genentech's allegation of prejudice. See id.; Baker Mfg. Co. v. Whitewater Mfg. Co., 430 F.2d 1008, 1014 (7th Cir.1970) (finding laches where patentee decided to remain silent until litigation would be worthwhile before suing). Therefore, the authority cited by Chiron does not preclude Genentech's royalty argument as a matter of law.
Nor is Genentech's argument without factual support. Sean Johnston, Genentech's Vice President of Intellectual Property who was involved in several of the licensing negotiations with Chiron, states in his declaration that "[h]ad Chiron filed and prosecuted in the United States Patent Office claims directed to non-murine monoclonal antibodies earlier than it did, or had Chiron discussed such claims with Genentech, Genentech might have acted differently." (Johnston Decl. ¶ 4.) Robert Garnick, Genentech's Senior Vice President of Regulatory Affairs, also attests that "Genentech might have taken a different approach in its discussions with Chiron regarding anti-HER2 antibodies."[5] (Garnick Decl. ¶ 3.) These declarations, coupled with the testimony of Chiron's experts regarding the economics of licensing agreements, are sufficient to create a disputed issue as to whether Genentech would have changed its economic position vis-a-vis Chiron had Chiron ffled the '561 patent earlier.
Chiron argues that because Genentech refused to license Chiron's patents, any increase in royalty raw is Genentech's own fault, and therefore cannot be attributed to Chiron's delay. However, Genentech did not have the option to consider the significance of the '561 patent when it declined to license Chiron's technology, because the '561 patent did not exist at a time when royalty rates would have been low. Genentech cannot have assumed the risk of not licensing a patent that did not exist.
Chiron also argues that Genentech would probably not have taken a license on the '561 patent had it issued earlier, because Genentech obtained an opinion letter of counsel stating tha: the '561 patent was invalid and not infringed, and Genentech had not taken a license on the '894 and '774 after obtaining similar opinion letters. While this evidence certainly supports Chiron's position, the appropriate time for the court to weigh this and other evidence is after a trial on the merits, not on summary judgment.
b. Designing Around the Patent
Genentech has also submitted evidence that it might have attempted to design around the patent. According to Mr. Garnick, Genentech may have considered designing a different breast cancer drug altogether. (Garnick Decl. ¶ 3). Mr. Garnick *1147 also suggests that Genentech could have manufactured Herceptin abroad, added more antibodies to Herceptin to make it a non-homogeneous preparation of antibodies, and then imported it back to the United States for sale. (Id ¶ 4.) By manufacturing Herceptin abroad, Genentech could have avoided the Patent Act's prohibition against making a patented invention in the United States. See 35 U.S.C. § 271(a) ("[W]hoever 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"). Because the '561 patent defines a monoclonal antibody as "an antibody composition having a homogeneous antibody population," (See '561 Patent at 8:4(M2), Genentech contends that it could have simply added more antibodies into the pure product manufactured abroad to make it non-homogeneous. Thus, according to Genentech, by the time the adulterated preparation was imported and sold in the United States, it would not have read onto the '561 patent, and therefore would not have run afoul of the Patent Act's prohibition against the importation, use, or sale of a patented invention in the United States. See 35 U.S.C. § 271(a).
Chiron argues that the latter alternative does not get around the patent, because infringement is not avoided by the addition of extra elements that do not eliminate an inherent feature of the patent's claims. Northern Telecom, Inc. v. Datapoint Corp., 908 F.2d 931, 945 (Fed.Cir.1990); SunTiger, Inc. v. Scientific Research Funding Group, 189 F.3d 1327 (Fed.Cir. 1999). Even if Chiron were correct that adding more antibodies to Herceptin would not have made the relevant population of antibodies heterogenous, Genentech is entitled to the benefit of every reasonable inference, which includes an inference that it could have and would have developed a different product entirely. Therefore, summary judgment in Chiron's favor is not appropriate.
Chiron protests that Genentech should be precluded from asserting prejudice on the basis of lost opportunities to design around the patent or to take a license at a lower rate. Chiron's argument is based on representations made by Genentech's counsel during a March 11, 2002 hearing on Genentech's motion for leave to amend its answer to add a prosecution laches defense. At that hearing, the court expressed concern that Chiron would not have adequate time to conduct discovery into the prejudice suffered by Genentech, given the late stage of the litigation at which the motion was brought. (See Mar. 11 Tr. at 41, 45-46.) Counsel for Genentech assured the court that the only prejudice Genentech suffered was that it spent millions of dollars developing Herceptin, and that much of the discovery into this injury had already been conducted in the case. (Id.) Relying in part upon Genentech's representations, the court granted Genentech leave to add a prosecution laches defense to its answer.
Genentech's current allegations of prejudice are not wholly inconsistent with the representations made at the hearing on the motion for leave to amend. However, the court has serious concerns about the additional prejudice to Chiron that may result if the court allows Genentech to litigate issues at trial that the court did not anticipate at the time the original decision was made to grant leave to amend. Therefore, the court will determine the laches question in a separate hearing after the jury trial, after Chiron has had an opportunity to conduct further discovery. The court's previous Order of April 12, 2002, will therefore be amended to permit Chiron to conduct open-ended discovery on *1148 laches until the time of the separate hearing on the issue.[6]
IT IS THEREFORE ORDERED that:
(1) Chiron's motion for summary judgment on Genentech's defense of prosecution laches be, and the same hereby is, DENIED;
(2) The court will hear Genentech's prosecution laches defense in a separate hearing that will take place after the jury trial, if the prosecution laches defense is not moot at that time;
(3) Chiron may conduct open-ended discovery on prosecution laches until the time of the separate hearing on the defense.
NOTES
[1] Chiron's predecessor, Cetus, prosecuted and obtained a number of the patents in the '561 patent family. Chiron now owns the rights to those patents. For ease of reference, the court does not distinguish between Cetus and Chiron when referring to events in the prosecution history of the '561 patent.
[2] The parties are in agreement that both of these elements must be established for Genentech to prevail on its defense.
[3] Chiron contends that the presumption does not apply in the context of prosecution laches, and that the period of delay was a mere five months. The court does not address the merits of these contentions.
[4] Chiron asserts that "Genentech confessed that it would not have done anything differently had the '561 patent claims issued earlier." (Chiron Mot. For SJ. Re: Laches in Prosecution, at 12.) However, the two pieces of evidence on which Chiron relies do not support this assertion. First, Chiron relies on Genentech's answer to Chiron's interrogatory asking what Genentech would have done differently "had Genentech not believed that Chiron abandoned its infringement allegations." (Riley Decl. Ex. 27, at 6) (emphasis added). Genentech's response that it would not have done anything differently does not answer the question of what Genentech would have done had Chiron prosecuted the '561 patent earlier. Second, Chiron relies on the deposition testimony of Steve Julesgaard, Genentech's General Counsel. However, in the portions of Mr. Julesgaard's deposition that Chiron cites, Mr. Julesgaard was explaining what Genentech's thought process was after the '561 patent issued, not what Genentech would have done had the '561 patent issued earlier. (See Julesgaard Dep. at 32.)
[5] Chiron moves to strike the declarations of Mr. Johnston and Mr. Garnick on the grounds that they are speculative and lacking in personal knowledge and are therefore inadmissible. However, Mr. Johnston was personally engaged in licensing negotiations with Chiron, and therefore is in a position to opine as to what Chiron might have done differently in those negotiations. Mr. Garnick attests that he has personal knowledge of Genentech's approaches to product development, including the considerations "hat Genentech gives to the intellectual property rights of others. Therefore, his observations about what Genentech might have done differently are also purportedly based on his own personal knowledge and experience. The court therefore will not strike these declarations from the record.
[6] Chiron has requested that in the event its summary judgment motion is denied, the court issue an order pursuant to Federal Rule of Civil Procedure 56(d) specifying facts that are established for trial. The court does not find it practicable in this case "to ascertain what material facts exist without substantial controversy and what material facts are actually and in good faith controverted" such that the court can issue a Rule 56(d) order. Fed. R. Civ. Proc. 56(d). Moreover, the court in its discretion does not choose to narrow issues or establish facts where doing so does not eliminate a claim or defense. In the court's experience, such piecemeal resolution of the case makes trial more difficult and complex as opposed to streamlined.
