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in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”).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

“arguments, and evidence presented in the parallel proceeding.” Fintiv at 12 (emphasis added). “[A] timely-filed Sotera stipulation . . . from a petitioner”—“that, if an IPR . . . is instituted, the petitioner will not pursue in district court . . . any ground raised or that could have been reasonably raised in the IPR”—“is highly relevant, but will not be dispositive by itself. Instead, the Board will consider such a stipulation as part of its holistic analysis under Fintiv.” March 2025 Fintiv Guidance 2–3.
