“stipulation would only eliminate the District Court’s consideration of Haddad204. Despite the stipulation, the District Court would still have to consider invalidity of every claim the Petition addresses and would still have to consider the Alie, Baggenstoss, and Park references. Cf. Stellar at 4 (“Petitioner’s invalidity arguments in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”). In other words, “Petitioner’s stipulation does not ensure that [this proceeding] would be a ‘true alternative’ to the district court proceeding.” Id. at 3–4. Because of the remaining overlap between the Petition and the District Court proceeding, Fintiv factor four weighs strongly in favor of discretionary denial.” slip op. at 15

“for back side illumination (BSI), which appears to teach or suggest a textured region with surface features “located on the light incident side of the semiconductor layer and configured to interact with incident [EMR].” Pet. 22–27 (citing Ex. 1006, Fig. 5, ¶¶ 53, 68, 96; Ex. 1004 ¶¶ 39–40, 88–95, 101–107). As Petitioner and its expert explain, a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device because BSI devices allow more incident light to reach the semiconductor layer, resulting in more light being absorbed, an increase in the quantum efficiency, and an improvement in the signal to noise ratio. Pet. 25–26 (citing Ex. 1006 ¶¶ 68, 70; Ex. 1004 ¶¶ 39–40, 92, 95). Patent Owner argues that Alie does teach, suggest, or disclose “a textured region comprising a plurality of shallow trench isolation features.” Prelim. Resp. 9–11. But it appears Petitioner has at least shown Alie teaches or suggests this element. See discussion supra. Patent Owner further argues that Petitioner fails to present any proof that a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device. Id. at 11–15. But, in our view, Petitioner has provided an adequate motivation to modify Alie—so that more light will be absorbed, yielding an increase in the quantum efficiency and an improvement in the signal to noise” slip op. at 18

“17 Petitioner filed petitions for IPR2025-00064 and IPR2025-00065 at the same time. Both petitions address the ’682 patent but apply different art. Patent Owner also argues the second petition (IPR2025-00065) should be denied because one petition is sufficient. Patent Owner’s Response to Petitioner’s Notice Ranking Parallel Petitions, Paper 11. Because we deny institution based on Fintiv discretion, it is not necessary to reach Patent Owner’s multiple petition argument.” slip op. at 20

The Board denied institution of PGR on claims 1–21 and 28–49 under § 324(a), finding likely duplication with parallel litigation and weak merits on most challenges.

“g. Holistic Analysis of Fintiv Factors We undertake a holistic analysis of these factors, considering “whether efficiency and integrity of the system are best served by denying or instituting review.” Fintiv, Paper 11 at 6. In this case, all of the factors weigh in Patent Owner’s favor except for the first factor, which is neutral, and the fifth factor, which weighs against denial. Specifically, the overlap of the parallel proceedings, including the stipulation by Patent Owner, and the weakness of the merits of Petitioner’s petition outweigh the factors in favor of exercising discretion to institute inter partes review. A balancing of the facts and circumstances as discussed above leads us to conclude, on this record, that the inefficient duplication of efforts here is likely. Accordingly, we determine that the circumstances presented weigh in favor of denying institution under 35 U.S.C. § 324(a).” slip op. at 27

“unpatentable over Rogers and Entchev. Pet. 105–112. Patent Owner also alleges that claims 4 and 32 are unpatentable over Rogers, Entchev, and Lembcke and that claims 19–21 and 47–49 are unpatentable over Rogers, Entchev, and Fishbeck. Id. at 113–114. Patent Owner asserts that Petitioner “does not show a motivation to combine Entchev and Rogers.” Prelim. Resp. 40. Specifically, Patent Owner asserts that Petitioner “has not shown or even argued that a POSA would have sought to incorporate the bridge plug of Entchev into a process that does not include a settlement location for the pieces of the bridge plug, like Rogers.” Id. at 42. Patent Owner asserts further that Petitioner has not “shown that a POSA would have combined the debris catching features in Entchev with Rogers.” Id. We find Patent Owner’s assertions credible. Upon our initial review of this ground, we find that Petitioner’s reasoning in support of the proposed combination is weak, which suggest that the merits of the challenges relying on the combination of Rogers and Entchev are weak, which weighs in favor of denying institution.” slip op. at 26

“this factor. At the time of our Decision, trial was scheduled in the parallel proceeding for December 7, 2020, approximately nine months before our final written decision would have been due, if we were to institute trial. Dec. 10–11. As such, this gap in timing created a cognizable risk of inconsistent results and duplication of efforts, which weighed toward denying institution. Id. at 6, 11–12. Additionally, the Decision notes that some uncertainty exists regarding trial dates, as Petitioner again argues in its Request. Id. at 11; Req. Reh’g 3–4. However, the Decision goes on to determine that even if trial in the parallel proceeding was delayed by two months, consistent with Petitioner’s prior requested delay, the proximity of the trial date to our final written decision would still favor denying institution. Dec. 12 (citing Ex. 2002, 2). As such, Petitioner has not shown that the Board misapprehended the trial date.” slip op. at 5

“Thus, unlike the Request, the Petition did not contend that a skilled artisan would have found it obvious that “[Cho’s communication] may comprise one player specifying, to the server, information identifying another player to be involved in the game.” Compare id. at 46–47, with Req. Reh’g 6–7 (emphasis added). To the contrary, the Petition simply stated that a skilled artisan would understand that Cho taught transmissions through a server, but did not state that it would have been obvious, in light of Cho’s teachings, for this transmission to include first information. As discussed in our Decision, the Petition’s reliance on GSB to supply the transmission of “first information” fails because Petitioner has not explained persuasively why it would have been obvious to transmit GSB’s first information when Cho already establishes a communication between players and because Petitioner fails to explain “how the additional transmission of identifying information would simplify communications or allow easier connection, over the communication that Cho already establishes.” Dec. 24.” slip op. at 9
- Other 314aDecided for patent owner
“different posture of PGR proceedings as compared to IPR proceedings, when exercising discretion to deny institution. As summarized above, the Decision discusses that common statutory language exists in § 314(a)— directed toward IPR proceedings—and in § 324(a)—directed to post-grant review proceedings. See supra § I.A; Dec. 5–7. The Decision also discusses the common policy justifications implicated when determining whether to institute either an IPR proceeding or a PGR proceeding. Id. at 7. The Decision then goes on to recognize and discuss certain differences between PGR proceedings and IPR proceedings. Id. Despite these differences, we determined that the Board’s binding precedential case law set forth in NHK Spring and Fintiv applies to this PGR proceeding. Id. In doing so, we additionally evaluated certain differences between PGR proceedings and IPR proceedings, when considering the Fintiv Order factors. See, e.g., id. at 12, 15–17, 20–21. Petitioner has not demonstrated that we abused our discretion in doing so.” slip op. at 11
