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in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”).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 14–16 and 18–20, exercising § 314(a) discretion under Fintiv because the ITC investigation was advanced and the preliminary merits were a closer call.

“In evaluating whether to do so, we consider the following factors in assessing “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. Fintiv at 5–6. In evaluating these factors, we “take[] a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review.” Id. at 6.” slip op. at 9

“B. Analysis Institution of an inter partes review is discretionary. See 35 U.S.C. § 314(a) (2018) (stating “[t]he Director may not authorize an inter partes review to be instituted unless the Director determines that 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”) (emphasis added); Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”). The advanced state of either a parallel district court action or a parallel ITC investigation may warrant exercising discretion on behalf of the Director to deny a petition for inter partes review. See NHK Spring Co. v. Intri-Plex Techs., Inc., IPR2018-00752, Paper 8 at 20 (PTAB Sept. 12, 2018) (precedential) (“NHK”); Apple Inc. v.

“Petitioner contends that Nokia discloses, “in the context of the disclosed handover operations, performing a contention free . . . RACH procedure (step 5 [of Nokia’s Figure 1]), wherein the identifier information necessary for the UE to communicate with the target base station during the RACH procedure was previously transmitted in a message from the source base station to the UE (e.g., Handover Command, Step 4).” Pet. 31 (citing Ex. 1037 ¶ 92). Petitioner motivates its reasoning for effecting a combination of Nokia with Hu by contending that a person of skill in the art “would recognize that the specific implementation of such a conventional, contention free RACH procedure as referenced in Nokia could be implemented using” a variety of known methods. Id. at 33. Such a person “would also have recognized,” Petitioner further contends, “that using conventional RACH procedures wherein each UE is assigned and uses its own different preamble would make the handover process quicker and more efficient by reducing contention between the mobile station and the other mobile stations on the RACH.” Id. Petitioner relies on such features to argue that “Hu discloses the full implementation level details of how such a conventional, contention free RACH procedure using allocated resources in the form of a dedicated code resource (i.e., a dedicated preamble) is performed.” Id. Patent Owner disputes Petitioner’s reading of Nokia, particularly that it discloses a contention-free RACH procedure. See Prelim. Resp. 36–43. Patent Owner correctly observes that the timing alignment in step 5 of Nokia’s Figure 1 “involves one of two different procedures: a ‘one or two step RACH procedure’ OR a ‘Non contention based access burst.’” Id. at 37. Patent Owner elaborates that, although Nokia teaches that the “UE receives allocation(s)” that can be used in an access burst in the second of these procedures, Nokia “does not even teach what an ‘access burst’ is or how it would be used in a non-contention-based manner—and certainly does not teach or suggest that the non-contention-based manner would involve a RACH procedure.” Id. at 38. Patent Owner further supports its position with “[o]ther contemporaneous submissions by Nokia [that] confirm this and explain what Nokia meant by a contention-free access burst procedure,” as well as LTE standards documents. Id. at 38–43 (citing Ex. 2009, 1–2; Ex. 2010 § 10.1; Ex. 2011 § 10.1.2.1; Ex. 2012 § 10.1.2.1). We have reviewed this evidence, and find on this record that it provides some support for Patent Owner’s position. The merits of this case thus present the “closer call” that favors exercising discretion to deny institution of an inter partes review under Fintiv.” slip op. at 18
