DECIDED: July 15, 2008
___________________________
Before GAJARSA, LINN, and DYK, Circuit Judges.
DYK, Circuit Judge.
In this contract case, plaintiff G. David Jang, M.D., alleges that defendants,
Boston Scientific Corporation (“Boston Scientific”) and Scimed Life Systems
Incorporated (“Scimed”) breached a contract with Jang by failing to make required
payments. The right to these payments depends on whether the sale of certain devices
by Boston Scientific and Scimed were “covered by” (i.e., would have infringed) U.S.
Patents No. 5,922,021 and 5,954,743 (“the ’021 patent” and “the ’743 patent,”
respectively), originally issued to Jang and later assigned to defendants. The district
court issued a claim construction order, and the parties entered into a stipulation
conceding that infringement could not be shown if the district court’s claim constructions
were upheld on appeal. The stipulation did not explain whether Jang’s success on
appeal in overturning any particular claim construction issue would, in fact, affect the
infringement dispute. At oral argument Jang conceded that resolution of the dispute, at
least as to one of the district court’s claim constructions, would not affect infringement,
and defendants appeared to agree. Moreover, even as to those claim construction
rulings that could affect infringement, it is not clear how the claim constructions would
render the accused products infringing or noninfringing. As a result of the ambiguity
both as to which claim construction rulings affect infringement and as to how those
rulings relate to the accused product, we vacate the judgment and remand to the district
court for clarification.
BACKGROUND
Jang is the named inventor of the ’021 and ’743 patents, relating to the design or
architecture of intravascular stents, tube-shaped mesh devices used to treat certain
forms of cardiac disease. Intravascular stents are inserted in a blood vessel and then
expanded (usually by use of a balloon catheter) to prop open a blocked or weakened
section of the vessel. In particular, the patents relate to the particular patterns of
repeated shapes that make up the stents and that allow them, among other things, to
exhibit radial strength when expanded, to be adequately flexible during insertion, and to
avoid foreshortening in length during expansion. See ’021 patent, col. 3, ll.23-46; ’743
patent, col.3, ll.13-34.
Through a contract executed in 2002, Jang assigned the ’021 and ’743 patents to
Boston Scientific and Scimed. In exchange, Boston Scientific and Scimed agreed to
2007-1385 2
pay $50 million immediately and agreed to pay an additional amount (up to $110 million)
based on the sales of commercial products covered by the assigned patents if such
products were produced, or a noncommercialization payment of $10 million if such
products were not produced. Boston Scientific and Scimed developed and sold several
stent designs that they asserted were not covered by the assigned ’021 and ’743
patents, and paid Jang only the initial $50 million payment and the $10 million
noncommercialization fee.
Jang filed his initial complaint in this action in the District Court for the Central
District of California on May 19, 2005. Boston Scientific and Scimed answered and
counterclaimed, and Jang filed a First Amended Complaint in March 2006. Jang’s First
Amended Complaint asserted, as the third alternative claim for relief, a claim for breach
of contract against defendants. Jang’s breach of contract claim asserted that four
models of commercial intravascular stents sold by Boston Scientific and Scimed were
“covered by” either or both of the ’021 and ’743 patents (i.e., would infringe the patents),
and thus that Jang was entitled to an additional payment of $100 million under the
assignment agreement. 1 The parties’ briefs on appeal neglect to advise us which
claims are asserted against the accused products. The district court held a claim
construction hearing on May 30, 2006. By apparent agreement of the parties, the claim
construction hearing focused on terms used in claim 1 of each of the asserted patents.
The district court issued a claim construction order on August 24, 2006,
construing the contested claim terms: “expansion column,” “connecting strut column,”
1
The first claim for relief in Jang’s First Amended Complaint, seeking
rescission of the contract, and the fourth claim for relief, asserting a breach of fiduciary
2007-1385 3
“connecting strut,” “expansion strut,” “expansion strut pair,” “proximal,” “distal,” and
“radius of curvature.”
After the district court’s claim construction order was issued, the parties entered
a stipulation, agreeing that under the district court’s claim construction, Jang could not
prove that the accused products were “covered by” (i.e., infringed) the asserted patents.
Accordingly, the parties agreed that partial summary judgment in favor of Boston
Scientific and Scimed should be entered on Jang’s breach of contract claim. The
stipulation expressly preserved Jang’s ability to challenge the claim construction order
on appeal. The stipulation did not explain why the district court’s claim construction
resulted in non-liability, other than to state that, “under the Court's existing Claim
Construction Order, Dr. Jang cannot prove that the Express stent is covered by any
claims of U.S. Patent Nos. 5,922,021 and 5,954,743 . . . .” J.A. at 19. 2 On September
duty, were also based, in part, on the failure by Boston Scientific and Scimed to make
the additional disputed $100 million payment.

In relevant part, the stipulation provided:
On or about August 24, 2006, the Court issued a Claim
Construction Order (“the Order”), which the parties received on August 28,
2006. Plaintiff Dr. Jang believes that the Court’s Order is incorrect in
several fundamental respects, and he intends to seek appellate review of
the Court’s Order in the appropriate appellate court. Nonetheless, the
parties agree that, under the Court’s existing Claim Construction Order,
Dr. Jang cannot prove that the Express stent is covered by any claims of
U.S. Patent Nos. 5,922,021 and 5,954,743, and therefore cannot prove
that Scimed breached the Assignment Agreement with respect to those
patents.
Accordingly, in order to conserve the resources of both the parties
and the Court, see, e.g., York Prods., lnc. v. Central Tractor Farm &
Family Ctr., 99 F.3d 1568, 1571 (Fed. Cir. 1996), the parties hereby
stipulate and agree, subject to the approval of this Court, and further
subject to the full and complete preservation of Dr. Jang's right to appeal
the Order, that an order of partial summary judgment should now be
entered against Dr. Jang and in favor of Scimed on Dr. Jang’s Third Claim
2007-1385 4
18, 2006, the district court entered partial summary judgment as to the breach of
contract claim based on the parties’ joint stipulation requesting this disposition. The
judgment did not explain how any of the disputed claim construction rulings related to
the accused devices.
This judgment was not yet final as to all claims, however, as other claims and
counterclaims remained outstanding. On January 30, 2007, the district court entered
partial summary judgment in favor of defendants as to two of Jang’s claims seeking
rescission of the agreement with respect to the ownership of certain other patents
relating to balloon angioplasty that originally issued to Jang. On May 8, 2007, the
district court signed a proposed consent judgment drafted by the parties which
incorporated the two prior judgments into a final judgment and granted declaratory relief
that the disputed balloon angioplasty patents “are not within the scope of Dr. Jang’s
assignment obligations to [Boston Scientific] under any current or past agreement
for Relief for Breach of Contract against Scimed. Similarly, because the
Defendants’ first and second counterclaims are now moot, the parties also
stipulate and agree, subject to the approval of this Court, that an order
should be entered dismissing those counterclaims without prejudice.
This Stipulation is wholly predicated on Dr. Jang’s right to obtain
appellate review of the Court’s Claim Construction Order. By entering into
this Stipulation, the parties agree that Dr. Jang is not waiving, but rather is
expressly reserving, his right to obtain appellate review of the Court’s
Claim Construction Order and to proceed further with his Third Claim for
Relief on remand from the Court of Appeals should the Court of Appeals
reverse or vacate this Court's Claim Construction Order in whole or in part.
Indeed, Dr. Jang’s fight to appeal the Court's Claim Construction Order is
an essential condition of this Stipulation, and if the Court does not agree
that Dr. Jang is fully preserving all of his rights to obtain appellate review
of the Claim Construction Order, then Dr. Jang does not consent to the
entry of an order granting partial summary judgment against him on his
Third Claim for Relief and requests that the Court reject this Stipulation.

between the parties.” J.A. at 29. The consent judgment also preserved Jang’s right to
appeal the district court’s claim construction rulings with respect to the ’021 and ’743
patents, and preserved Jang’s “right to pursue his breach of fiduciary duty and
rescission claims in the event the Court of Appeals reverses or vacates [the district
court’s] claim construction order.” Id. at 30. 3
Jang timely appealed from the final consent judgment, challenging only the
district court’s claim construction with respect to the ’021 and ’743 patents. At oral
argument on appeal, counsel for plaintiff admitted that resolution of at least one of the
claim construction disputes would not affect the issue of infringement. 4 Defendants also
acknowledged that the dispute as to whether “expansion column” includes a “vertical” or
“tubular” requirement “is not crucial here” and would not affect the issue of infringement.

argument that that he did not consider resolution of this dispute relevant to the issue of

In full, this paragraph of the consent judgment provided as follows:
Dr. Jang waives his right to appeal the Court’s order dated January
30, 2007, granting in part and denying in part [Boston Scientific’s] motion
for summary judgment; such waiver, this Consent Judgment, and the
Court’s Order dated January 30, 2007, are all without prejudice to Dr.
Jang’s right to pursue his breach of fiduciary duty and rescission claims in
the event the Court of Appeals reverses or vacates this Court’s claim
construction order dated August 25, 2006, to the extent such claims are
not based upon the now-resolved dispute between the parties pertaining
to the scope of Dr. Jang’s assignment obligations under the Assignment
Agreement and Employment Agreement . . . .

In relevant part, counsel for plaintiff stated: “In fact, I don’t think that the
issue of tubularness versus non-tubularness has anything to do with infringement, and
similarly there is another word in there, vertical--a vertical extension of space as
opposed to a ring of space, that’s another one that I don’t think is pertinent to the issue
of infringement.” Oral Argument at 2:43-3:03.

in our brief, we do not think that is a material dispute and we would not have addressed
it [if Jang had not]. . . .”). We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1). 5
DISCUSSION
I
It is clear that a judgment entered based on a stipulation of the parties may in
appropriate circumstances be reviewed on appeal. Indeed, this court has reviewed
stipulated judgments based on claim construction when the judgments were entered
with the express purpose of obtaining appellate review of the claim construction. See,
e.g., Oatey Co. v. IPS Corp., 514 F.3d 1271, 1276 (Fed. Cir. 2008); Ventana Med. Sys.,
Inc. v. Biogenex Labs., Inc., 473 F.3d 1173, 1177 (Fed. Cir. 2006); Generation II
Orthotics Inc. v. Med. Tech. Inc., 263 F.3d 1356, 1363 (Fed. Cir. 2001); Interactive Gift
Express, Inc. v. Compuserve Inc., 256 F.3d 1323, 1330 (Fed. Cir. 2001). However, a
consent judgment must satisfy the same standards of appellate jurisdiction as any other
judgment entered by the district court. See, e.g., United States v. Procter & Gamble
Co., 356 U.S. 677, 680-81 (1958). A judgment is reviewable only if it is possible for the
appellate court to ascertain the basis for the judgment challenged on appeal.
5
Although this case arises from a contract claim, rather than directly as a
patent infringement claim, Jang’s right to relief on the contract claim as asserted in the
complaint depends on an issue of federal patent law—whether the stents sold by
Boston Scientific and Scimed would have infringed the ’021 and ’743 patents. See
Christianson v. Colt Indus. Operating Corp., 486 U.S. 800, 808-09 (1988) (explaining
that this court has authority over appeals in cases where, inter alia, “a well-pleaded
complaint establishes . . . that the plaintiff's right to relief necessarily depends on
resolution of a substantial question of federal patent law, in that patent law is a
necessary element of one of the well-pleaded claims”); U.S. Valves, Inc. v. Dray, 212
F.3d 1368, 1372 (Fed. Cir. 2000) (concluding that “patent law is a necessary element of

The Supreme Court has recognized the authority to remand for clarification
judgments that suffer from ambiguity, particularly when the ambiguity implicates
jurisdictional concerns. See, e.g., Bush v. Palm Beach County Canvassing Bd., 531
U.S. 70, 78 (2000) (remanding because there was “’considerable uncertainty as to the
precise grounds for the decision[]’” from which the appeal was taken (quoting Minnesota
v. Nat’l Tea Co., 309 U.S. 551, 555 (1940))); see also Dennison Mfg. Co. v. Panduit
Corp., 475 U.S. 809, 811 (1986) (remanding for clarification due to the “lack [of] an
adequate explanation of the basis for the Court of Appeals’ judgment”). The Courts of
Appeals in general and our court in particular have recognized that a remand for
clarification is appropriate where a judgment is ambiguous. 6

valves that were covered by the licensed patents” to prevail on that claim).

See, e.g., Nazomi Commc’ns, Inc. v. ARM Holdings, PLC, 403 F.3d 1364,
1371-72 (Fed. Cir. 2005) (remanding for clarification of noninfringement ruling due to
“the absence of findings of fact on the nature of the accused device” and of claim
construction based on inadequate analysis that did not “supply [a] basis . . . sufficient for
a meaningful review”); Superior Fireplace Co. v. Majestic Prods. Co., 270 F.3d 1358,
1377 (Fed. Cir. 2001) (remanding for clarification of conclusion that case was not
exceptional for purposes of attorney’s fees award because “the district court’s failure to
provide any findings or reasoning prevents us from reviewing its decision”); Telectronics
Pacing Sys., Inc. v. Ventritex, Inc., 982 F.2d 1520, 1526 (Fed Cir. 1992) (noting that a
remand for clarification of a judgment entered through summary judgment is appropriate
“if the ‘district court’s underlying holdings would otherwise be ambiguous or
inascertainable’” (quoting Hanson v. Aetna Life & Cas., 625 F.2d 573, 575 (5th Cir.
1980))); Bott v. Four Star Corp., 807 F.2d 1567, 1574-75 (Fed. Cir. 1986) (remanding
for clarification of ambiguity as to the amount of damages the district court intended to
award), overruled on other grounds by A.C. Aukerman Co. v. R.L. Chaides Const. Co.,
960 F.2d 1020 (Fed. Cir. 1992); Cable Elec. Prods., Inc. v. Genmark, Inc., 770 F.2d
1015, 1020 (Fed. Cir. 1985) (recognizing that remand for clarification may be necessary
when the logic of a judgment under review “cannot be discerned”), overruled on other
grounds by Midwest Indus., Inc. v. Karavan Trailers, Inc., 175 F.3d 1356 (Fed. Cir.
1999); see also In re Frillette, 423 F.2d 1397, 1400-01 (CCPA 1970) (remanding for
clarification of ambiguity as to whether patent application was rejected for lack of
enablement or for indefiniteness of claim language).

II
In this case, the consent judgment under review suffers from two ambiguities. As
a result, we conclude that it is appropriate to remand this case to the district court for
clarification.
A
First, it is impossible to discern from the stipluated judgment which of the district
court’s claim construction rulings would actually affect the issue of infringement. Here,
plaintiff challenges seven aspects of the district court’s claim construction on appeal:
(1) the interpretation of “expansion column” to require a “tubular” structure and the
failure to require that the expansion column be “vertical;” (2) the interpretation of
“expansion column” as being formed “solely” of expansion strut pairs; (3) the
interpretation of “connecting strut column” as formed “solely” of connecting struts; (4)
the interpretation of “connecting strut column” as requiring the individual connecting
struts within the column to be unattached to each other; (5) the interpretation of
Our sister circuits have similarly recognized the authority to remand for
clarification of ambiguous judgments, and have applied this principle both in the context
of judgments entered through summary judgment and other ambiguous orders. See,
e.g., Couveau v. Am. Airlines, Inc., 218 F.3d 1078, 1081 (9th Cir. 2000) (per curiam)
(“[W]hen multiple grounds are presented by the movant and the reasons for the district
court’s decision are not otherwise clear from the record, [the court] may vacate a
summary judgment and remand for a statement of reasons.”); Campbell v. Hewitt,
Coleman & Assocs., Inc., 21 F.3d 52, 55 (4th Cir. 1994) (remanding for clarification
when it was unclear what formed the basis for district court’s entry of summary
judgment); E.E.O.C. v. Erection Co., 900 F.2d 168, 170 (9th Cir. 1990) (remanding for
clarification of ambiguous order sealing consent decree); Hanson, 625 F.2d at 575
(remanding for clarification of basis for judgment entered through summary judgment
order); Bonanno v. Thomas, 309 F.2d 320, 321 (9th Cir. 1962) (remanding for
clarification as to basis for order of dismissal).
Since the issue concerning the need for clarification is inherently related to patent
law (and our claim construction jurisprudence) this issue is governed by Federal Circuit
2007-1385 9
“connecting strut” to require that it connect struts in “adjacent” expansion columns; (6)
the interpretation of “expansion strut” to mean a strut in an expansion column; and (7)
the interpretation of “expansion strut pair” to require a combination of two adjacent
expansion struts attached on one side and not the other.
The parties extensively brief the first of these issues, whether the term
“expansion column” should be interpreted to require a tubular structure. At oral
argument, counsel for plaintiff conceded that the district court’s construction of the claim
term “expansion column” to include a “tubular” rather than a “vertical” limitation was not
“pertinent to the issue of infringement.” Oral Argument at 2:43-3:03. Defendants’
appellate brief concedes that the issue concerning any “tubular” or “vertical” limitation
has no effect on infringement, and counsel for defendants again admitted at oral
argument that there was not “a material dispute” between the parties as to this issue.
Oral Argument at 34:50-35:04. It appears possible that other claim construction
disputes may also not affect infringement. 7 Given the sparse record and the lack of any
explanation as to which constructions would support a judgment of infringement, we
cannot determine with certainty which of the claim construction disputes actually has an
effect on the infringement issue.
If we did not require clarification of the stipulated judgment in this case, we would
risk rendering an advisory opinion as to claim construction issues that do not actually
affect the infringement controversy between the parties. The Supreme Court has
law. See Diego Inc. v. Audible, Inc., 505 F.3d 1362, 1366 (Fed. Cir. 2007) (issues
“unique to patent law” governed by Federal Circuit law).
7
At oral argument, Jang’s counsel listed the claim construction issues that
did and that did not affect infringement, but omitted two claim construction issues raised
2007-1385 10
explicitly held that Article III does not permit the courts to resolve issues when it is not
clear that the resolution of the question will resolve a concrete controversy between
interested parties. Coffman v. Breeze, 323 U.S. 316, 322-24 (1945) (“[F]or purposes of
the present suit, the constitutionality of the Act is without legal significance . . . . The
prayer of the bill of complaint that the Act be declared unconstitutional is thus but a
request for an advisory opinion . . . .”); see also Calderon v. Ashmus, 523 U.S. 740, 747
(1998) (refusing to apply statute to hypothetical dispute because the resulting
determination would be only an advisory opinion and would not “resolve the entire case
or controversy”); United States v. Evans, 213 U.S. 297, 300-01 (1909) (refusing on
advisory opinion grounds to consider merits of government’s appeal as to jury
instructions in criminal case where statute conferring appellate jurisdiction required that
acquittal could not be set aside); Yazoo & Miss. Valley R.R. v. Jackson Vinegar Co.,
226 U.S. 217, 219-20 (1912) (refusing to decide dispute as to constitutionality of statute
in hypothetical contexts that would not affect the outcome of the case before the court).
These concerns strongly counsel in favor of a remand for clarification of the judgment.
B
Second, the stipulated judgment provides no factual context for the claim
construction issues presented by the parties. In particular, nothing in the stipulated
judgment provides any context with respect to how the disputed claim construction
rulings relate to the accused products.
We have previously emphasized the importance of the context provided by an
analysis of the accused device when ruling on claim construction and the problems
in Jang’s brief, that is, the district court’s construction of the terms “expansion strut” and
2007-1385 11
presented by construing claims in the absence of such context. For example, in Lava
Trading, Inc. v. Sonic Trading Management, LLC, we noted the difficulty of construing
claims without the ability to compare the accused products to the asserted claims:
Without knowledge of the accused products, this court cannot assess the
accuracy of the infringement judgment under review and lacks a proper
context for an accurate claim construction. . . . Without the vital contextual
knowledge of the accused products or processes, this appeal takes on the
attributes of something akin to an advisory opinion on the scope of the
[asserted] patent. The problems with such an appeal, even if within this
court's jurisdiction, have been noted in many of the court's prior cases.
445 F.3d 1348, 1350 (Fed. Cir. 2006) (internal citation omitted) (citing Wilson Sporting
Goods Co. v. Hillerich & Bradsby Co., 442 F.3d 1322 (Fed. Cir. 2006)); see also Mass.
Inst. of Tech. v. Abacus Software, 462 F.3d 1344, 1350 (Fed. Cir. 2006) (noting “a
problem with the mechanism by which th[e] case ha[d] been litigated . . . [because] the
record d[id] not disclose the nature of the accused devices”). Indeed, a better
understanding of the context of the claim construction as a case proceeds through an
infringement determination can appropriately lead a district court to change its initial
claim construction. See, e.g., Power Mosfet Techs., L.L.C. v. Siemens AG, 378 F.3d
1396, 1412 (Fed. Cir. 2004); Sofamor Danek Group, Inc. v. DePuy-Motech, Inc., 74
F.3d 1216, 1221 (Fed. Cir. 1996) (“A trial court may exercise its discretion to interpret
the claims at a time when the parties have presented a full picture of the claimed
invention and prior art.”).
Where a stipulated judgment of noninfringement has been entered based on a
district court’s claim construction and the stipulated judgment itself does not explain the
basis for the infringement determination, we have sometimes elected to proceed with an
“expansion strut pair.”
2007-1385 12
appeal challenging the claim construction because we could sufficiently infer the factual
context from the record. See, e.g., Lava Trading, 445 F.3d at 1351; Mass. Inst. of
Tech., 462 F.3d at 1351. However, where this has not been possible, we have declined
to resolve the claim construction issue. See Wilson, 442 F.3d at 1331 (noting that the
context for a “rigid” limitation included in the district court’s claim construction was
unclear and refusing to reach a final construction in this regard on appeal while inviting
the district court to “reconsider its construction” as to the “rigid” limitation on a fuller
record).
This is not a case in which the impact of the constructions is obvious from a
simple examination of the record documents. While the record contains depictions of
the accused products and the parties offer cryptic comments in their appeal briefs on
the infringement issue, there is no explanation in the stipulation as to why the accused
products would not infringe under the district court’s claim construction or why they
would infringe under the alternative claim constructions offered by Jang. Nor is it
possible to infer this information from the record. It is, in fact, not even clear from the
stipulation or from the briefs on appeal which claims of the two patents are asserted.
The lack of information concerning infringement makes it difficult to comprehend the
claim construction issues. In other words, on this record, we lack “a proper context for
an accurate claim construction.” Lava Trading, 445 F.3d at 1350. Under these
circumstances we conclude that a remand for clarification is both necessary and
appropriate.
2007-1385 13
CONCLUSION
For the reasons set forth above, we vacate the “Consent Judgment” entered by
the district court, and remand this case for further proceedings not inconsistent with this
opinion.
