      “These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum. The Petition does not explain why so many grounds are necessary under the circumstances or why the Board should impose on Patent Owner the burden of defending against so many challenges. See generally Pet. An inter partes review based on 24 distinct grounds raised against a single claim, supported by analysis lacking in particularity, potentially burdens Patent Owner unduly and makes inefficient use of the Board’s resources. See PTAB Consolidated Trial Practice Guide (Nov. 2019),22 56 (“The AIA was ‘designed to establish a more efficient and streamlined patent system that will improve patent quality and limit unnecessary and counterproductive litigation costs.’” (quoting H.R.

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. Due to the dependency of claims 15 and 16 from claim 14, and for the same reasons as those explained above addressing claim 1, based on the record before us Petitioner does not set forth sufficient argument and evidence to demonstrate that the combination of Doshi, Guichard, and Ashwood Smith teaches or suggests the limitations of claims 15 and 16.

    • 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.

Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied. Accordingly, we do not construe any claim terms expressly because express constructions are not necessary to resolve the controversy before us. See Realtime Data, 912 F.3d at 1375.” slip op. at 12

      “At this stage of the proceeding and on the present record, we adopt Petitioner’s uncontested proposed level of ordinary skill in the art, which we find consistent with the level of ordinary skill in the art reflected by the ’071 patent and the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 12

    • BurdenNot shown unpatentable

      “We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89. But, as noted above, Jin does not disclose an element referred to as a “pilot parameter” and it is not clear what element Dr. Min intended to identify in Jin.8” slip op. at 18

      “To prevail on its obviousness challenges, Petitioner must show that the ’848 patent is not entitled to the benefit of the ’330 application. This issue is dispositive because none of the references relied on by Petitioner qualify as prior art if the ’848 patent is entitled to the benefit of the May 26, 2005, filing date of the ’330 application. Pet. 6, 13. We start by explaining why Petitioner bears the burden of persuasion.” slip op. at 9

    • BurdenDecided for patent owner

      “1. The Burden of Persuasion “In an inter partes review . . ., the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence.” 35 U.S.C. § 316(e). That burden, termed the burden of persuasion, “is the ultimate burden assigned to a party who must prove something to a specified degree of certainty.” Dynamic Drinkware, LLC v. National Graphics, Inc., 800 F.3d 1375, 1378 (quoting Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1326–27 (Fed. Cir. 2008)). That burden never shifts to the patentee. Id. at 1379. In order for an inter partes review to be instituted, “the information presented in the petition filed under section 311 and any response filed under section 313 [must] show[] that there is a reasonable likelihood that the petitioner would prevail.” 35 U.S.C. § 314(a).” slip op. at 9

      “d) Analysis Petitioner has not shown a reasonable likelihood that it would prevail in showing that its asserted references, including Steuer 750 which is a publication of the ’330 application, are prior art to the ’848 patent. Petitioner has not shown that the ’330 application fails to provide written description support for claim 1 of the ’848 patent, which recites “video data” samples and representations.” slip op. at 16

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Not reached

      “a chain of priority from the ’330 application to the ’848 patent contain at least the same disclosure as the ’330 application, Petitioner has not shown that the ’848 patent should not be given the benefit of the effective filing date of the ’330 application. The May 26, 2005 filing date of the ’330 application predates the December 1, 2005 publication date of Steuer 750, the August 13, 2013 issue date of Steuer 768, and the December 2, 2010 and May 27, 2010 publication and filing dates of Neumeier.10 Pet. 7; Ex. 1005, code (43); Ex. 1006, code (45); Ex. 1007, codes (43), (60).11 Therefore, Petitioner has not shown by a preponderance of the evidence that any of the asserted claims in the ’848 patent would have been obvious over the asserted combinations of Steuer 750, Steuer 768, and Neumeier.” slip op. at 22
