The Board denied institution of IPR challenging claims 1–44 under § 314(a), finding the Fintiv factors favoring denial outweighed the Petition’s strong merits.

“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in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”).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 IPR challenging claims 1–5 and 8–14, exercising § 314(a) discretion under Fintiv because the factors favored denial and the merits were not compelling.

“We consider the following factors to assess “whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits.

“We have authority to institute an inter partes review where a petitioner shows a reasonable likelihood of prevailing with respect to at least one challenged claim. 35 U.S.C. § 314(a); 37 C.F.R. § 42.4(a). Under appropriate circumstances, however, we may exercise our discretion under Section 314(a) and deny review without regard to whether the petitioner has met that threshold. Trial Practice Guide,3 64; see 84 Fed. Reg. 64,280 (Nov. 21, 2019). For reasons that follow, we exercise our discretion under Section 314(a) and do not institute an inter partes review.” slip op. at 2

“On this record, we discern a genuinely-disputed issue surrounding the correct construction of the first wavelength spectrum limitation. Specifically, a question arises whether the first wavelength spectrum limitation can be 13 Neither party identifies the litigation involving Petitioner’s real parties-ininterest as related to this proceeding.

Compare Pet. 23–25, 57–58, with Prelim. Resp. 64–74. To be clear, we need not and, therefore, do not resolve the correct construction of the first wavelength spectrum limitation. It is enough for us to observe, on this record, that a genuinely-disputed issue surrounds this issue of claim construction. As explained in the next section, that dispute casts doubt upon whether Petitioner shows sufficiently, for purposes of trial institution, that the prior art suggests the filter transparency limitation.” slip op. at 15

“14 Petitioner belatedly suggests that an ordinarily skilled artisan would have been prompted to replace the emitter material employed by the prior art (namely, BCzVBi in DPvBi) with a different, but undisclosed, emitter material having “no significant emission at wavelengths above 500 nm.” Opp. Supp. Br. 2 (citing Ex. 2010 ¶ 43); see Reply 3–4 (same). That argument is not presented in the Petition, much less supported in the Petition by a rationale to combine. See Pet. 16–17, 48–50 (mapping the organic layer sequence of claim 1 to the organic layer sequence of Igarashi or Shiotani, which both employ BCzVBi in DPvBi as the emitter material (Ex. 1004 ¶ 88; Ex. 1005, 5/12)).” slip op. at 17
