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in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”).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 rehearing, leaving in place its denial of institution for claims 16–17 based on the Fintiv factors and its § 314(a) discretion.

“When rehearing a decision on institution, the Board reviews the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may arise if the decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if an unreasonable judgment is made in weighing relevant factors. Star Fruits S.N.C. v. U.S., 393 F.3d 1277, 1281 (Fed. Cir. 2005); Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004); In re Gartside, 203 F.3d 1305, 1315–16 (Fed. Cir. 2000). The burdens and requirements of a request for rehearing are stated in 37 C.F.R. § 42.71(d): The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. Thus, a request for rehearing is not an opportunity to present new arguments or evidence or merely to disagree with the panel’s assessment of the arguments or weighing of the evidence.” slip op. at 3

“the evidence laid out an approximate time frame for when the trial would likely be held. Dec. 9 (citing Ex. 2003); see also id. at 8–9 (citing PO Resp. 35; Ex. 1026) (Discussing the Court’s Procedures and timeline for trial after the docket call). Thus, we determined that this factor favored denying institution under our analysis of the factors under Fintiv. Id. at 9.” slip op. at 4

“Petitioner acknowledges that the proposed combination of the references relies on “us[ing] the cumulative totals of the flow rates of the unblended components in the Hoffman compensation process” (id.), however Patent Owner identifies that Hoffman appears to teach away from using the flow rates of the unblended components in its calculations because of the uncertainty in the flow rate of the blended line. Prelim. Resp. 19, 21– 22. Contrary to Petitioner’s position, it is not Patent Owner’s burden to show why “a person of ordinary skill in the art would be discouraged from measuring flow rates upstream for use in the Hoffman compensation process” (Reh. Req. 9), but rather, Petitioner bears the burden to show why a person of ordinary skill in the art would measure flow rates upstream for use in the Hoffman compensation process in view of the all of the teachings of the references (35 U.S.C. § 314(a) (Institution only authorized if “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.”)).
