“(which we address in more detail below) turns on the determination of the meaning of the claim term “periodically.” We note that the District Court has construed the term “periodically monitor” to mean “monitor at regular intervals of time.” See Sec. II.C below. Given this construction, which we preliminarily agree with at this stage, we cannot agree with Petitioner that the Petition presents “a strong case for obviousness.” Thus, we find that Factor 6 weighs in favor of exercising discretionary denial.” slip op. at 16

“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. From this evidence, we are persuaded that we should rely on the trial” slip op. at 9

“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.

“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.

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?

Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources.

Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims.

In our Rehearing Decision, however, we agreed with Patent Owner that we erred in determining the claim terms “first format” and “second format” are not limited to different formats, and determined that the proper construction of these claim terms indeed requires the two formats to be different formats. Reh’g Dec. 5–9, 19. Applying the proper construction, we further determined that none of Petitioner’s asserted challenges presents compelling merits of unpatentability as to any claim of the ’751 patent, 6 Available at https://www.uspto.gov/sites/default/files/documents/interim_ proc_discretionary_denials_aia_parallel_district_court_litigation_memo_20 220621_.pdf. 7 Our analysis of the first five Fintiv factors in our First Institution Decision remains undisturbed on rehearing. contrary to our initial determination in the Institution Decision.

“Contrary to Petitioner’s position, Patent Owner met its burden of showing that our Institution Decision should be modified. In our Institution Decision, we relied on claim differentiation when we determined that claim 1 is not limited to different first and second formats. Inst. Dec. 31. We did not consider the prosecution history, which was part of the record. See Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed. Cir. 2005) (“[W]e have held that a court ‘should also consider the patent’s prosecution history, if it is in evidence.’”). As we noted in our Rehearing Decision, however, the Federal Circuit has explained that “[t]he prosecution history modifies the scope of a claim term if ‘the patentee distinguished that term from prior art on the basis of a particular embodiment, expressly disclaimed subject matter, or described a particular embodiment as important to the invention.” Reh’g Dec. 8 (quoting Sentry Protection Prods., Inc. v. Eagle Mfg. Co., 400 F.3d 910, 915 (Fed. Cir. 2005)). The Federal Circuit also has explained that “[a]lthough claim differentiation is a useful analytic tool, it cannot . . . relieve any claim of limitations imposed by the prosecution history.” Id. at 13 (quoting Fenner Invs., Ltd. v. Cellco P’Ship, 778 F.3d 1320, 1327 (Fed. Cir. 2015)). In other words, we erred in not considering the prosecution history, which led to our erroneous conclusion that claim 1 is not limited to different first and second formats. See Ex. 1104, 170 (prosecution history). Our Institution Decision was based on this erroneous conclusion of law, as Patent Owner argued, and we modified it accordingly.” slip op. at 9

“claim 1. As discussed above with respect to limitation 1D, Petitioner asserted that its proposed combination of Danciu and Mahajan would have provided a system where “Danciu’s remote control would translate commands associated with a first type of media playing application to a generic format, transmit them to the controlled device, which would translate them to a command associated with a second type of media playing application for execution.” Reh’g Dec. 12–13 (quoting Pet. 31). In other words, both Danciu’s remote control and controlled device translate commands. With respect to claim 5, Petitioner asserted that Mahajan’s abstraction module could operate at Danciu’s server. Pet. 43. Even if Mahajan’s abstraction module (which translates commands) could operate at Danciu’s server, Petitioner does not adequately explain why an ordinarily skilled artisan would have had reason to modify Danciu’s system to locate Mahajan’s abstraction module at the server, especially where both Danciu’s remote control and controlled device already translate commands. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[T]here must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”).

“denial because district court is very likely to address patentability issues at trial before we would issue a final written decision. Factors 3 and 4 weigh marginally against discretionary denial. Factor 5 either weighs in favor of discretionary denial or is neutral, but even if it were neutral, factor 2 alone outweighs the marginal weight of factors 3 and 4. Based on our assessment, we determine that Fintiv Factors 1–5 favor exercising discretion to deny institution. With that determination in mind, we proceed to evaluate Fintiv Factor 6. G.

“We further note that Petitioner’s general view that it would have been obvious to a person of ordinary skill in the art to modify Jung to arrive at the pertinent limitation is not well supported and somewhat circular. See Pet. 42–43. It is inadequately explained why a skilled artisan would have reasonably sought to modify Jung so that it then “expressly teaches” what is required by the claims, as is advanced by Petitioner. See id. at 42. It is a dubious proposition that simply seeking to account for the requirements of the challenged claims serves as suitable reasoning that would have prompted modification of the “express[] teach[ings]” of a reference.” slip op. at 25

“proceeding. See Pet. 12. Patent Owner provides a construction of the phrase “to derive, based on a beam reference signal of the network beam, a UE beam,” which Patent Owner contends is not necessary to substantiate its arguments, but is offered to “elucidate[] the distinction between the ’868 Patent and the alleged prior art from the reasons” offered by Patent Owner in its Preliminary Response. PO Resp. 8. In particular, Patent Owner contends that the above-noted phrase means “selecting a UE beam from a plurality of candidate UE beams based on a beam reference signal of the network beam.” Id. Patent Owner explains the basis for its proposed construction of the relevant phrase through citation to content of the ’868 patent including Figures 21 and 22 of the patent along with description of those Figures.

The Board denied institution under Fintiv, finding that the parallel district court proceedings would likely address patentability before a final written decision and the merits were not compelling.

“In Fintiv, the Board explained that “cases addressing earlier trial dates as a basis for denial under NHK Spring have sought to balance considerations such as system efficiency, fairness, and patent quality.” Fintiv, Paper 11 at 5. Fintiv sets forth six non-exclusive factors for determining “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.” Id. at 6. These factors consider the following: 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. Id. at 5–6. In evaluating these factors, “the Board takes 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 8

“2. Claim Construction In interpreting the claims of the ’402 patent, we “us[e] the same claim construction standard that would be used to construe the claim[s] in a civil action under 35 U.S.C. [§] 282(b).” See 37 C.F.R. § 42.100(b) (2020). The claim construction standard includes construing claims in accordance with the ordinary and customary meaning of such claims as would have been understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. See id.; Phillips v. AWH Corp., 415 F.3d 1303, 1312–14 (Fed. Cir. 2005) (en banc).

“outset, we note that the language of claims 1 and 12 is clear in reciting the presence of two distinct signals, i.e., a control signal and a reference signal, and that it is the control signal that “triggers” transmission of the reference signal. See Ex. 1001, 14:5–6, 60–62. Patent Owner credibly argues that the “two-step embodiment” of Figure 10 of the ’402 patent, and in particular steps 1005 and 1010, describe the control and reference signal transmissions that are encompassed by claims 1 and 12. See Prelim. Resp 8–10. Patent Owner also credibly argues that the Figure 10 embodiment is distinct from other disclosed embodiments, including the “single-step embodiment” of Figure 8. See id. at 10–11. Patent Owner further explains reasonably that the content of column 6 of the ’402 patent on which Petitioner relies has a more “natural reading” in distinguishing between separate transmission of a “control signal” that “triggers” separate transmission of a “reference signal” as described in connection with Figure 10 as juxtaposed with transmission of a “control channel,” which is distinct from a control signal, and a “reference signal” that may constitute a single transmission, as is described in conjunction with Figure 8. See id. at 16–17. It logically follows that if, as Patent Owner credibly argues, the claims of the ’402 patent do encompass the latter transmission scheme, rather than the former, then Petitioner’s reliance on Moon, as presented in its Petition, is insufficient to account for those claims. On this record, we need not decide whether Petitioner would likely prevail on the above-noted issues as Patent Owner raises sufficiently substantial arguments that the preliminary evidence, if unrebutted in trial, does not plainly lead to a conclusion that claim 1 is unpatentable by a preponderance of the evidence. Because, as noted above, Patent Owner has identified potentially dispositive gaps or flaws in Petitioner’s apprehension as to what is adequate in Moon’s disclosure to account for the claims of the ’402 patent, Petitioner’s proposed grounds cannot be said to rise to the level of a “compelling” meritorious challenge.” slip op. at 22
