While we do not make a determination regarding whether the Petition shows that there is a reasonable likelihood of prevailing were we to institute, for the reasons given, we determine that this Petition does not present particularly strong merits. G. Weighing the Fintiv Factors We have considered the circumstances and facts before us in view of the Fintiv factors. We take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. 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. A balanced assessment of the factors leads us to exercise discretion to deny the Petition. Therefore, we conclude that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review.” slip op. at 22

    “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.

    “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

    “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.

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.

The District Court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 17.

    “integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. 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. A balanced assessment of the factors leads us to exercise discretion to deny the Petition. Therefore, we conclude that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review challenging claims 1, 2, 6, 7, 23, 25, 31, 53, 68, 70–72, 74, and 75.

    “The parties each raise facially valid points based on the claim language. Petitioner has the burden to show “[h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104 b(3). Petitioner does not explain how, under its broad construction, the decoder “decodes the encoded data to recover application and control bits in accordance with a line code.” That is, if the encoding does not encode both “application and control bits,” then how can decoding “recover” both under Petitioner’s claim construction? It is not clear on this preliminary record whether the specification supports Petitioner’s broad claim construction. For this reason, Petitioner’s showing based upon the broad claim construction outlined above is not “particularly strong.” See Fintiv at 14–15.

    “the claims nor the specification of the ’294 Patent require such a narrow reading of the term ‘activation cue’” as that proposed by Patent Owner. Reply 1 (citing Prelim. Resp. 9–10). Operative claim language—“a cue receiver operatively linked to said electronic circuit for receiving an activation cue from a source external to said cellular phone”—does not limit “activation cue” to a predetermined bit sequence or predetermined indicator as argued by Patent Owner. Claim 1 further recites the “data conveyance switching element . . . being assigned a first state upon an activation cue having been received by said cue receiver,” which also does not limit “activation cue” to a predetermined bit sequence or predetermined indicator. Both parties, moreover, cite the same description of the structure and function of the “activation cue” in the ’294 patent: “This activation cue is in the form of a data communication of a specific type which will be recognized by electronic device 10 as an activation cue, for example a predetermined bit sequence.” Prelim.
