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.

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.

The fact that the time-to-trial statistic is earlier than the scheduled trial date confirms that the scheduled trial date is credible and should be given weight.

Because of the Sotera stipulation, factor 4 weighs strongly in favor of not exercising discretion. However, two other factors weigh in favor of exercising discretion, especially the trial date factor. The merits of Petitioner’s challenge are not particularly strong.

      “partes review “allays concerns about inefficiency and duplication of efforts,” and strongly weighs against exercising our authority to deny institution. Fintiv, Paper 11 at 6. Of the three district court proceedings, the Lenovo Group case, pending in the Eastern District of Texas, is the most significant to our analysis here. In the Lenovo Group case, Lenovo Group has not requested a stay. Prelim. Resp. 16. Patent Owner argues that the Lenovo Group case is not likely to be stayed based on that court’s low grant rate in other cases and the progress of that case in particular. Id. at 17. The district court in the HP case denied a stay without prejudice and stated that a stay could be reconsidered in the future depending on the outcome at the PTAB. Prelim. Reply 3. The Dell case has been stayed. Id. On this record, we decline to speculate as to how any of the involved district courts where no stay is pending might rule on any future motion to stay. Thus, we determine that, while one stay has been granted, the lack of a stay in the other underlying district court cases, especially the Lenovo Group case, is not sufficiently persuasive to weigh this factor against exercising discretion. Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 15 at 12 (PTAB May 13, 2020) (informative), cautions against speculating whether the district court would grant a stay if one were requested. Therefore, this factor has a neutral effect on the overall balancing of the Fintiv factors. B. Proximity of Trial Date to Projected Statutory Deadline (Factor 2) The scheduled trial date for the Lenovo Group case is November 3, 2025, which is about six months prior to the expected date for the final written decision here (i.e., late April 2026). See Prelim. Resp. 20; IPR2024- 01429, Ex. 2002 (Lenovo Group case Docket Control Order), 1. Petitioner argues this trial date is uncertain. Prelim. Reply 3. Further, Petitioner focuses its argument on what it terms a “growing backlog” in the Eastern District of Texas and “associated scheduling uncertainty.” Id. at 4. Petitioner refers to the status of the HP case, which is currently set for trial on September 21, 2026, and the stay in the Dell case. Id. Patent Owner responds that “[b]oth the scheduled trial date and the date of trial [in the Lenovo Group case] based on median time-to-trial statistics occur months before a final written decision would be expected here.” Prelim. Sur-reply 4. Patent Owner asserts that the time-to-trial statistics for the Eastern District of Texas project a median time-to-trial of 21.9 months. Prelim. Resp. 20–21 (citing Ex. 2007, U.S. District Courts Federal Court Management Statistics–Profiles—September 30, 2024). This projection yields a trial date that is prior to the expected final written decision date of April 2026. Prelim. Sur-reply 4. As with the previous factor, the status of the Lenovo Group case is our focus here. As stated, that trial is set to occur about six months before a final written decision would issue in this proceeding. The district court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 20. We are not persuaded by Petitioner’s unsupported argument that the trial date is uncertain. We also consider the fact that the median time-to-trial statistic discussed by both parties projects a trial date earlier than the actual date set by the district court. Ex. 2007; Prelim. Sur-reply 1. The fact that the time-to-trial statistic is earlier than the trial date set in the Lenovo Group case confirms that the schedule set by the district court is credible and should be given weight.

      “E. Conclusion Regarding the Merits Petitioner does not present particularly strong merits. Petitioner’s arguments on the “bus limitation,” to succeed at trial, would require addressing a claim construction issue that was never addressed in the Petition and is arguably contradicted by the ’520 patent, which discloses transmitting packets representing a plurality of different control signals on a single bus. See Prelim. Sur-reply 2 (citing Ex. 1001, 7:34–38, 9:23–25, 9:50–54). Similarly, prevailing on the “modified protocol” issue would require proving that the HDMI–C protocol, which uses the same separate channel arrangement for CEC and DDC as standard HDMI, is sufficiently “modified” to meet the claim. Taking into account Patent Owner’s persuasive arguments supra in response, and for the reasons given, we do not find the merits of Petitioner’s position on either of these dispositive issues to be particularly strong.” slip op. at 20

      “and only to the extent necessary to resolve the issues in dispute. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999); Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Neither party proposes claim constructions for our consideration. Petitioner submits that it “for the purposes of this proceeding, the terms of the challenged claims should be given their plain and ordinary meaning, and no terms require specific construction.” Pet. 8. Patent Owner does not dispute Petitioner’s position that no terms require construction. Prelim. Resp. 11–12. We determine there are no claim terms that need to be expressly construed for this Decision.” slip op. at 15

    • Skill levelDecided for patent owner

      “Patent Owner states that a person of ordinary skill “would have the equivalent of a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent training and three years of work experience with data communications systems or interfaces, including at least some experience with serial or display data communications systems or interfaces .” Prelim. Resp. 12. The differences between these nearly-identical definitions are minor and immaterial to our decision. We regard either description as consistent with the challenged patent and the prior art before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill).” slip op. at 16

      “example, claim 11 recites “receiving a synchronization symbol by a receiver indicating a packet type, each packet type having a different synchronization symbol.” Ex. 1001, 37:53–55. The other independent claims challenged in the Petition are similar in their recitation of a “synchronization symbol.” See id. at 37:9 (claim 1), 38:26–27 (claim 19). Petitioner argues this limitation is disclosed by Auld in view of MPEG-2 Part. 1. Pet. 15–16. Citing Figure 5 of Auld, reproduced in Section IV.C.1, supra, Petitioner asserts that “[t]he ‘sync codes’ in Auld consist of sequences of symbols that are used for synchronization, and therefore qualify as synchronization symbols.” Id. at 17. Patent Owner responds that “what the Petitioners identified as a ‘synchronization symbol’ [in Auld] is in what they have identified as a ‘packet of (or having) symbols.’” Prelim. Resp. 1. In contrast, “[i]n the specification and claims of the ’798 Patent, the claimed ‘synchronization symbol’ is separate from, and precedes, the claimed ‘packet of (or having) symbols.’” Prelim. Resp. 1. In disputing Petitioner’s identification in Auld of a synchronization symbol as claimed, Patent Owner points to Figure 9A of the ’798 patent (reproduced in Section II.C, supra), showing synchronization primitives 901 and 905 as separate from and transmitted before packets 902 and 907, respectively. Id. at 4. Patent Owner also relies on the description of the Figure 9A embodiment in the ’798 patent specification. Id. at 3–5. That description places transmission of the synchronization primitive encoded with the patent type before the control packet in the transmission sequence:” slip op. at 18
