    “B. Level of Ordinary Skill in the Art As noted above, resolving the question of obviousness requires determination of the level of ordinary skill in the art. Graham, 383 U.S. at 17–18. Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner. The absence of such assessment calls into question the fundamental adequacy of Petitioner in carrying its burden to show a reasonable likelihood of success of unpatentability of the challenged claims that necessarily must take into account the level of ordinary skill in the art.” slip op. at 10

In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art.

    “We agree with Patent Owner and find that Petitioner does not sufficiently explain why the skilled artisan, given Mahieux, would have had a rational reason to modify Mahieux to keep track of, let alone make use of, perceptibly significant frequency bands. Indeed, Patent Owner’s declarant, Dr. Kyriakakis, persuasively testifies why modifying Mahieux to do so would have made no sense to the skilled artisan: It would not have made sense to modify Mahieux’s system to instead count the number of audible frequency bands (e.g., the number of audible frequency bands B1-B3), as such a count would play no role in Mahieux’s bit allocation. Indeed, as Mahieux’s bit allocation focuses on the number of non-zero coefficients in each individual frequency band in isolation and without regard to the aggregate number of total audible frequency bands of the overall spectrum, generating an aggregate number of total audible frequency bands (e.g., by counting) serves no purpose in Mahieux’s allocation scheme. Further given Mahieux’s focus on allocating bits to frequency coefficients in individual frequency bands in isolation from other bands, [the skilled artisan] would fail to find any use for such an aggregate number or count. Ex. 2002 ¶ 92 (cited at Prelim. Resp. 23). Thus, we find Petitioner does not sufficiently explain why modifying Mahieux to keep track of perceptibly significant frequency bands would have presented itself to the skilled artisan as an option at all, let alone an option that would have been obvious to try.

    “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. See 37 C.F.R. § 42.65(a).” slip op. at 22

    “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. See Ex. 1003 ¶¶ 256–258; Ex. 1005 ¶¶ 142–145; Fig. 11.” slip op. at 18

    “(‘POSITA’) would have had a working knowledge of network communications and multiprotocol label switching (‘MPLS’) techniques available at the time.” Pet. 11 (citing Ex. 1003 ¶¶ 50–51). Petitioner contends that “[a] POSITA would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent training, and approximately two years of experience working in the field of network communications and been knowledgeable regarding MPLS techniques.” Id. (citing Ex. 1003 ¶ 51). Patent Owner does not address the skill level of a person of ordinary of skill in the art. See Prelim. Resp. For the purpose of determining whether to institute trial, we adopt Petitioner’s definition of a person of ordinary skill in the art because it is consistent with the level of skill reflected by the ’821 Patent Specification and the asserted prior art.” slip op. at 8

    “disclosed in the manner provided by the first paragraph of section 112 of this title in an application previously filed in the United States . . . shall have the same effect, as to such invention, as though filed on the date of the prior application.” (emphasis added). “In essence, this means that in a chain of continuing applications, a claim in a later application receives the benefit of the filing date of an earlier application so long as the disclosure in the earlier application meets the requirements of 35 U.S.C. § 112, ¶ 1, including the written description requirement, with respect to that claim.” Technology Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1326 (Fed. Cir. 2008). And to determine whether a parent application meets the written description requirement, “the disclosure must be considered as a whole, as the person of ordinary skill in the art would read it, to determine if it reasonably conveys possession” of the claimed invention. Allergan USA, Inc. v. MSN Labs. Private Ltd., 111 F.4th 1358, 1375 (Fed. Cir. 2024) (citation and emphasis omitted); see also Reiffin v. Microsoft Corp., 214 F.3d 1342, 1345–46 (Fed.

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

    “A claim is unpatentable under 35 U.S.C. § 103(a) 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). The question of obviousness is resolved on the basis of underlying factual differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) if presented, objective evidence of non-obviousness. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). As previously noted, the first factor regarding the scope of available prior art is the dispositive issue of this Petition, which is largely defined by the effective filing date of the challenged claims.” slip op. at 8

    “Because we determine that no inter partes review will be instituted on IPR2024-01350, we find it unnecessary to exercise exclusive jurisdiction over the ’849 patent. See Paper 9, 9. Therefore, Petitioner’s motion for the Board to exercise exclusive jurisdiction over the ’849 patent is denied. Petitioner further requests that all briefing in this proceeding be provided to the Certificates of Correction and Petitions branches for their consideration, citing Patent Owner’s “duties of candor and good faith.” Id. at 2, 10.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “B. Level of Ordinary Skill in the Art Petitioner, supported by Dr. Min’s testimony, proposes that a person of ordinary skill in the art at the time of the invention would have had “at least a bachelor’s [degree] in [electrical engineering, computer engineering, or computer science], physics, or equivalent, and two years of experience with cellular telecommunications, radio-access network architectures, protocols and signal propagation in wireless networks.” Pet. 3 (citing Ex. 1003 ¶ 59). Dr. Min testifies that “[a]dditional education could substitute for professional experience and vice versa.” Ex. 1003 ¶ 59. Additionally, Petitioner contends that Dr. Min “exceeded this level of experience by the priority date.” Pet. 3 (citing Ex. 1010 (curriculum vitae of Dr. Min)). In its Preliminary Response, Patent Owner does not take a position on the relevant level of ordinary skill in the art. See generally Prelim. Resp. 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 ’946 patent and the prior art of record.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached

    “Neither party contends that any claim terms require an express construction to resolve the present controversy. Pet. 8 (“For purposes of this Petition only, Petitioner does not believe any terms require a formal construction.”); see generally Prelim. Resp. Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. 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
