      “decision in Revvo Technologies, Inc. v. Cerebrum Sensor Technologies, Inc., IPR2025-00632, Paper 20 (Nov. 3, 2025 (“Revvo”)).12 Revvo provides that “when a petitioner takes alternative positions [on claim construction] before the Board and a district court, that petitioner should, at a minimum, explain why alternative positions are warranted.” Revvo at 3–4. On November 5, 2025, the Director of the Office issued an informative decision in Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025- 00340, Paper 18 (Nov. 5, 2025) (“Tesla”)). Tesla provides that: “Allowing a petitioner to advance a claim construction before the Board when that petitioner has made inconsistent indefiniteness arguments in district court fails to further, but instead detracts from, the Office’s goal of ‘providing greater predictability and certainty in the patent system.’” Id. at 4 (citing Revvo at 4–5). Tesla further provides that when a petitioner raises inconsistent invalidity challenges in two forums, “that petitioner is required to explain why those different positions are warranted.” Id. at 3 (citing Revvo at 3–5). In this proceeding, Petitioner takes alternative positions on claim construction before the Board and a district court, but fails to explain why alternative positions are warranted. Therefore, in accordance with Revvo and Tesla, we deny institution.” slip op. at 6

Additional education can substitute for less work experience, and vice versa. Pet. 14; see Ex. 1003 ¶ 41. Patent Owner does not dispute or comment on this proposal or propose an alternate level of ordinary skill in the art. Based on a review of the record, we adopt Petitioner’s proposed level of ordinary skill in the art, which is consistent with the evidence of record, including the asserted prior art and ’103 patent.” slip op. at 14

See Phillips, 415 F.3d at 1313–14. Neither Petitioner nor Patent Owner asserts that any claim term requires claim construction (Pet. 14–15; Prelim.

      “2. Conclusion Regarding the Merits The discussion above identifies weaknesses in the Petition that we have considered in our evaluation of Fintiv factors. 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

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Institution denied

      “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

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “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. 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.

Accordingly, there is not a reasonable likelihood that Petitioner would prevail in showing that the subject matter of independent claim 14 would have been obvious over Doshi, Guichard, and Ashwood Smith.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “We agree with Patent Owner’s arguments. We find that Petitioner does not show sufficiently that Ashwood Smith discloses, teaches, or suggests “digital logic . . . configured to determine a probability of concurrent failure of a working entity and a protection entity,” as required by claim 14. Petitioner implicitly construes “digital logic . . . configured to determine a probability of concurrent failure of said working entity and said protection entity” to require “calculat[ing] the probability of concurrent failure of the paths.” Pet. 77; see also id. (“calculating such probability for two paths”), 78 (also implicitly construing “digital logic . . . configured to determine an entity cost of said plurality of transport entity descriptors” to require “cost calculation”). We agree with Petitioner’s implicit construction because it is consistent with the claim language and the ’821 Patent Specification which discloses a simultaneous failure probability (SFP) function (Eq. 1) and SFP values calculated by a concurrent failure probability matrix. See Ex. 1001, 3:44–47, 6:5–11, 6:39–40. Similar to Doshi’s description of the probability of failure in terms of “very insignificant” (see Ex. 1005 ¶ 40), Petitioner’s cited disclosures of Ashwood Smith describe the probability of failure at a common point in terms of “fairly low” (see Ex. 1037, 3:21–23) “highly unlikely” (see Ex. 1037, 10:32), and “below a certain level” (see Ex. 1037, 11:7–8). Although Petitioner asserts that Ashwood Smith’s method determines the probability of failure at a common point between two paths (see Pet. 67), the teachings of Ashwood Smith cited by Petitioner do not support a finding that Ashwood Smith discloses, teaches, or suggests “digital logic . . . configured to determine the probability of concurrent failure,” as implicitly construed by Petitioner to require calculating a probability of concurrent failure of a working entity and a protection entity. Petitioner also cites Ashwood Smith’s disclosure suggesting a possible refinement to the disclosed method that would take into account the actual probability of failure at a common point shared by two or more working paths. See Ex. 1037, 10:21–24. Petitioner, however, does not direct us to any disclosure in Ashwood of digital logic configured to determine or calculate the probability of failure at a common point. See Pet. 66–69, 74–78. Instead, Petitioner overlooks Ashwood Smith’s disclosure that the probability of failure at a common point is allocated (i.e., distributed, assigned, given out) by the data transport network operator. See Ex. 1037, 11:4–6. This allocation of failure probability by the data transport operator is similar to the ’821 Patent Specification’s disclosure that “[s]pan failure probabilities may be assigned, for example, manually by a network operator based on network knowledge” and “[n]ode failure probabilities may be configured by the operator, typically based on vendor-provided mean time between failure (MTBF) parameters, and on infrastructure failure probability, for example, power failure probability.” Ex. 1001, 6:20–23, 6:29–33. We also give little weight to Petitioner’s witness Dr. Min’s testimony (Ex. 1003 ¶¶ 234–237) that Ashwood Smith teaches determining a probability of concurrent failure of two paths because, for the same reasons, it is not supported by an underlying factual basis.

      “IPR2023–00402, we find that Doshi does not disclose, teach, or suggest “digital logic . . . configured to determine a probability of concurrent failure of said working entity and said protection entity,” as required by claim 14. Although Doshi discloses selecting a subset of path pairs based on cost (see Ex. 1005 ¶ 144, Fig. 11), and that disjoint path pairs may have very insignificant probability of failure, Petitioner does not direct us to where Doshi discloses, teaches, or suggests “digital logic . . . configured determine the probability of concurrent failure of the primary path and the restoration path.” See Pet. 67, 74–76. We also give little weight to Petitioner’s witness Dr. Min’s testimony (Ex. 1003 ¶ 255) that determining path disjointedness corresponds to determining a probability of concurrent failure is entitled to little weight because, for the same reasons, it is not supported by an underlying factual basis. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). For example, Petitioner does not provide a factual basis for equating a determination of path disjointedness (e.g., strictly disjoint, partially disjoint) with a determination of the probability of concurrent failure of the primary and restoration path. We also give little weight to Dr. Min’s testimony (Ex. 1003 ¶ 258) that Doshi’s disclosure of selection logic configured to perform the method of Figure 11 teaches logic configured to determine probability of concurrent failure of said working entity and said protection entity because it also is not supported by an underlying factual basis.

      “1. Legal Standards “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to the patent owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). A patent claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007) (hereafter cited as “KSR”). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness, if made available in the record, which has not happened here.

      “To be sure, the pixel belief values used in the Luo-250 device are based on color. The Luo-250 device determines pixel probabilities “by assigning to each pixel a belief value as belonging to the subject matter region based on color and texture features.” Id. ¶ 42. However, using probability values or binary 1s and 0s to map the probability or “belief” that a pixel or area of pixels in an image either is, or is not, a subject matter target, is not the same as designating “certain pixels as certain colors” as asserted by Petitioner. Thus, we are not persuaded that the Petition has adequately supported or explained how the Luo-250 device designates “certain pixels as certain colors.” We also are not persuaded the Petition has established that Luo-250 discloses, teaches, or suggests a device or method that “determines the color range exhibited by the pixel data groups” as recited in Limitation 1[b]. Pet. 17–18 (citing Ex. 1005 ¶¶ 34–39). First, as indicated above, we are not persuaded the Petition has established that Luo-250 “designates certain pixels as certain colors,” which is foundational to Petitioner’s argument that the Luo-250 method determines a “color range exhibited by the pixel data groups.” Second, the evidence cited by Petitioner when attempting to map the quoted claim language regarding “color range” to Luo-250, refers to the designation of individual pixels as “either skin-tone or non skin-tone” in a binary belief map, not a range of colors. Id. at 18 (citing Ex. 1005 ¶¶ 35–39). Petitioner’s argument—that “[b]y analyzing the pixels to designate each as ‘either skin-tone or non skin-tone,’ Luo-250’s device determines ‘[r]egions of skin-tone colored pixels’ in the image” (id.)—is not persuasive evidence of “determin[ing] a color range exhibited by the pixel data groups” as recited in Limitation 1[b]. The Petition does not adequately explain how Luo-250 discloses, teaches, suggests, or otherwise renders obvious the determination of color ranges for pixel data groups in an image. We are further persuaded by Patent Owner’s argument and evidence that the Petition has not adequately explained how the Luo-250 device would “determine[] a color range” based on a determination of probability values for each pixel, rather than a range of colors. Prelim. Resp. 26–27 (citing Ex. 1005 ¶¶ 32, 34, 36, and 38). Dr. Papanikolopoulos’s Declaration testimony further supports Patent Owner’s position. Ex. 2001 ¶¶ 78–81. Dr. Papanikolopoulos testifies, in particular, that Mr. Parulski asserts only “that Luo-250 considers the color of individual pixels. He does not assert that Luo-250 anywhere ‘analyzes the image data . . . and determines the color range, as claimed.’” Id. ¶ 80. We agree.” slip op. at 22

      “Based on the preliminary record, we can reasonably expect trial in the parallel district court proceedings to begin four to five months prior to the deadline for our final written decision, based on the scheduled trial date and the median time-to-trial statistics. See Fintiv Memo 8–9 & n.12 (approving the use of median time-to-trial statistics). Even if the proceedings are staggered, at least one of the proceedings would likely begin and conclude well before our decision, making it highly likely that there will be duplicate efforts in evaluating the challenged claims based on the prior art.
