“Id. The Director neither addressed the merits of Petitioner’s challenges nor found that our prior consideration of those merits was faulty. Accordingly, we understand that we need not reconsider our conclusion that Petitioner had demonstrated a reasonable likelihood of proving that claims 1, 2, 7–9, 11, 12, and 20–24 were unpatentable or that the merits of patentability set forth in the Petition warranted institution of inter partes review.” slip op. at 5

“The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation. Accordingly, we find that, at this stage of the proceeding, it is undisputed that Patent Owner’s interpretations of the claim terms represent the “single claim construction that best captures the true meaning of the patent claim.”8 Under that claim interpretation, we” slip op. at 8

“We disagree with this argument because it is not consistent with the ’953 patent specification or the plain meaning of “replace.” Neither party requested a special construction of the term “replace.” We see no merit in Petitioner’s contention that the plain meaning of “replace” in Figure 32 does not require removal of the device being replaced. The contention that the plain meaning of “replace” does not require “removing” was explored with Petitioner’s counsel at the oral argument: THE BOARD: If you replace a player in a football game or baseball game, a new player goes in and replaces that player. You don't add a 12th, a 12th player or a 10th player to a baseball team. You replace the player that’s there with a different player. Isn’t that what replacement is all about?

“For the foregoing reasons, we determine that judicial estoppel and waiver apply. Accordingly, the certificates of correction for inventorship have no impact on the Final Written Decisions in these cases. We also note that if judicial estoppel and waiver had been found not to apply and these proceedings were recommenced under changed inventorship, Petitioner should be permitted the opportunity to respond to Patent Owner’s new inventorship of the patents-at-issue at least by being allowed additional briefing in order to comply with due process and the Administrative Procedure Act (APA). See Pet. Remand Br. 1. Additionally, if judicial estoppel and waiver had been found not to apply, we also would likely have to determine whether the source code evidence, in view of the related testimonial evidence and argument that is already in the trial record, supports the actual reduction to practice prior to Janevski’s effective date, as Patent Owner argues it does. See Paper 13, 28–31; Paper 22, 12–22. Amongst other things, this determination would likely entail resolving a claim construction dispute between the parties that may affect the determination of whether the source code practices the claimed invention. See Paper 22, 15–16. IV.

“Here, unlike Egenera, Patent Owner represented and provided evidence on its asserted correct inventorship directly to the Board. As discussed, Patent Owner asserted and provided evidence that Messrs. Balassanian and Bradley were the inventors of the patents and Mr. Carpenter implemented the invention. Paper 13, 19–20; Ex. 2001 ¶¶ 6, 33, 42, 46; see also Ex. 1019, 59:9–18. Patent Owner’s representations were not contested by Petitioner during trial, and Patent Owner’s representations were further consistent with the argument and evidence developed and considered by the Board during trial. Now, Patent Owner’s position on inventorship is inconsistent with its earlier position and Petitioner would be prejudiced absent estoppel. Accordingly, in this particular circumstance, judicial estoppel applies. Judicial estoppel is an equitable doctrine that prohibits a party from taking inconsistent positions in the same or related proceedings and its purpose is “to protect the integrity of the judicial process.”” slip op. at 20

“We agree with Petitioner that after Patent Owner was unsuccessful at trial due to the failure of its own evidence, Patent Owner now seeks to have the evidence reconsidered under changed inventorship. Pet. Remand Br. 8– 9. Patent Owner had in its sole possession the evidence of inventorship, and we believe that under these circumstances, Patent Owner should be held to the consequences of its choices as to the representations and evidence of antedating that it presented at trial. To hold otherwise would result in prejudice to Petitioner. We consider the potential prejudice to be significant; as discussed, redoing these proceedings would require Petitioner to expend additional resources. Further, under these specific circumstances where Patent Owner has made the inventorship change under its volition, Patent Owner would be afforded the unfair advantage of a “do-over,” absent the application of judicial estoppel. Accordingly, under these specific circumstances, we determine that judicial estoppel applies precluding Patent Owner from relying on the certificates of correction of inventorship in these proceedings.” slip op. at 21

“B. Judicial Estoppel Petitioner argues that judicial estoppel applies here to preclude the retroactive effect of § 256. Pet. Remand Br. 6–9. Petitioner asserts that judicial estoppel applies against a party when: (1) the party takes a later position that is “clearly inconsistent” with an earlier position; (2) the party succeeds in persuading a court to adopt the earlier position (which thus poses a “risk of inconsistent court determinations”); and (3) the party seeking to assert an inconsistent position would derive an unfair advantage or impose an unfair detriment on the opposing party if not estopped. Id. at 7 (citing Transclean Corp. v. Jiffy Lube Intern., Inc., 474 F.3d 1298, 1307 (Fed. Cir. 2007)).
