      “Decision is a final written decision under 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73 as to the patentability of claims 1–16 of the ’980 patent. We determine Petitioner has shown by a preponderance of the evidence that claims 1–3, 5–7, 9–11, and 13–15 are unpatentable, and Petitioner has not shown by a preponderance of evidence that claims 4, 8, 12, and 16 are unpatentable.” slip op. at 2

      “being present in another image or comparing that probability to a detection threshold.”). Dr. Saber was consistent with this testimony on cross-examination. Ex. 1051, 167–251. When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language. For this additional reason, I would not find that Petitioner has met its burden.” slip op. at 84

      “2. Reasons for Obviousness Based on Zhao On a limitation-by-limitation basis, Petitioner’s contentions of “obviousness” are primarily assertions of how a POSITA would have understood Zhao’s disclosures. For example, with regard to claim 1, Petitioner repeatedly asserts how “a POSITA would have understood Zhao” (Pet. 13, 18, 21, 27) and for each limitation contends that Zhao “disclosed or at least rendered obvious” (or a variation thereof) the limitation (id. at 13– 15, 17–18, 21, 23, 25–27).

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal. See PO Resp. 13 (“this Response establishes that Petitioner’s arguments fail even under its preferred definition of the level of ordinary skill”).” slip op. at 12

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notNot reached

      “We need not resolve this dispute because we reach the same ultimate conclusion that Petitioner shows, by a preponderance of the evidence, that claims 1, 3, 5, 9, 12, 13, and 15 are unpatentable, but not that claims 20 and 21 are unpatentable, even if we apply Patent Owner’s proposed construction that the preambles are limiting and the first and second data files must be different. See Reply 15 (Petitioner asserting that “there is no need to construe the preambles as the prior art meets them even if construed”); Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). For purposes of this Decision, we accordingly treat the preambles of independent claims 1 and 9 as limiting, and with the recited “first data file” and “second data file” as distinct data files.4” slip op. at 14

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

      “We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous. See Reply 3. We accordingly adopt the definitional construction provided by the” slip op. at 16

    • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundDecided for petitioner

      “As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed Cir. 2003) (citing Digital Biometrics, Inc. v. Identix, Inc., 149 F.3d 1335, 1347 (Fed. Cir. 1998)) (emphasis added). As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass. Inst. of Tech. v. Shire Pharms., Inc., 839 F.3d 1111, 1119 (Fed. Cir. 2016). And “[s]tatements by the patent owner are not considered in a vacuum; rather, the skilled artisan would look at the record as a whole in assessing claim scope.” Galderma Lab’s v. Amneal Pharma, 806 F. App’x 1007, 1010 (Fed. Cir. 2022) (citing Wang Labs., Inc. v. Toshiba Corp., 993 F.2d 858, 867 (Fed. Cir. 1993) (“The prosecution history must be examined as a whole in determining whether estoppel applies.”)). We have reviewed the prosecution history, which we summarize supra § I.A.3., and we have particularly reviewed those portions highlighted by Patent Owner. See PO Resp. 32–40. We reach the same conclusion as the district court in the Starz litigation that the standard for attachment of prosecution disclaimer is not met. See Ex. 1018, 109:15–22 (district court stating at Markman hearing, “I’ve also carefully reviewed the portions of the prosecution history relied on by VideoLabs, including the patentee’s arguments regarding the Shin and Rosenau references, and I’m up [sic: not6] persuaded there was a clear and unmistakable disclaimer of all assignment rules that perform assignments by using exact timing information”). slip op. at 20

      “time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham, 383 U.S. at 17. Petitioner asserts a person of ordinary skill in the art (“POSITA”) at the time of the invention “would have at least a Master’s Degree in Electrical Engineering or equivalent field, including studies in designing data converters, and two to five years of relevant experience; or a Ph.D. degree in Electrical Engineering or equivalent field.” Pet. 34 (citing Ex. 1202 ¶¶ 17–18). Patent Owner does not address the level of ordinary skill in the art in its Response. See generally PO Resp.

      “Even were we to accept Petitioner’s contention, that a ‘“random clock’ can be satisfied by a 1-bit pseudo-random bit sequence,” (Pet. 36), Jamal discloses that the alleged random clock C[m] “is uncorrelated with the input signal.” Ex. 1205, 8. A chopping SHA multiplies the input signal and the uncorrelated random signal C[m], then provides a chopped analog signal to the ADC converter. Id. Petitioner has not persuasively shown that chopping an input signal with an uncorrelated random signal, then providing the chopped signal to a converter as disclosed by Jamal, describes “said random clock configured to decorrelate an input signal provided to said first converter from said random clock” as recited in claim 1. We find that claim 1 is not unpatentable based on Jamal. Because claims 2 and 4–6 depend from claim 1, we find that these claims are also not unpatentable based on Jamal.” slip op. at 15

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITANo construction neededDecided for petitioner

      “We agree with Patent Owner regarding the ordinary meaning of the term “respectively.” Specifically, we understand that the word “respectively” can be an adverb that means “for each separately or in turn, and in the order mentioned.” The use of “respectively” as an adverb in the English language requires parallelism. See Ex. 3002. In other words, there must be a direct one-to-one correspondence and specific referents must be individually identified before there can be a “parallel list” of attribute values applicable to each, in that order. The term “respectively” also can be an attributive adjective that means “concerning or appropriate to each of several individually.” Id. In the present case, the term “respectively” appears to modify “the selected distributed devices.” Because specific referents are not individually identified, we understand the term to act as an attributive adjective modifying each of several selected distributed devices. Although we agree with Patent Owner regarding the use of the term “respectively,” we do not understand its use to require “the selected distributed devices to cause each selected distributed device to separately appear to network-connected user devices as a dedicated NAS device.” We cannot construe individual terms in isolation. Rather, we must consider claims as a whole in view of the specification. Specifically, we must consider the implications of other terms recited in claims 1 and 13 (e.g., “location information”) and how the claims are supported by the disclosed embodiments.” slip op. at 11

      “Patent Owner contests Petitioner’s definition of a person of ordinary skill in the art, specifically arguing that “Petitioners’ proposed requirements especially with regard to work experience, are higher than can be reasonably supported.” PO Resp. 5. Patent Owner notes that Petitioners’ declarant, Dr. Kubiatowicz, testified on cross-examination that “somebody coming directly out of college, likely, would need a couple of extra years to understand this,” and that “a little bit of professional experience might help them -- would help them understand the details involved in this case.” Id. (citing Ex. 2002, 25:13–14; 26:2–5). Patent Owner’s declarant, Dr. Shenoy, testified that, “at the time of the ’827 patent, a person of ordinary skill in the art should have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent, with 1–2 years of work experience in the field of computer networking, storage systems, or a related field.” Ex. 2003 ¶ 19. According to Dr. Shenoy, “[l]ack of experience can be remedied by additional education or vice versa.” Id. Based on our review of the ’827 patent, the types of problems and solutions described in the ’827 patent and cited prior art, and the testimony of Dr. Kubiatowicz and Dr. Shenoy, we adopt and apply Patent Owner’s definition of a person of ordinary skill in the art, specifically that a person of ordinary skill in the art at the time of the claimed invention would have had “a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent, with 1–2 years of work experience in the field of computer networking, storage systems, or a related field.” See id.

      “Despite Patent Owner’s arguments, we find that Carter’s policy element 290 (a software module) is configured to assess unused or under-utilized storage resources in selected distributed devices of the plurality of distributed devices. We understand policy element 290 to satisfy this limitation because Carter specifically discloses that policy element 290 “acts as a controller to determine the availability of resources, such as printer capabilities, hard-disk space, available RAM and other such resources.” Ex. 1140, 36:27–29 (emphases added). We credit the testimony of Dr. Kubiatowicz, who during his deposition stated, “I would say this policy controller certainly can evaluate the hard disk space on the local node, but could also potentially evaluate storage throughout the system by communicating with other nodes.” Ex. 2002, 86:13–16; see id. at 88:5–7; see also id. at 88:12–16 (“What I said was that this policy element is determining the availability of resources. So it’s assessing whether or not hard disk space of various sorts is available. So it’s availability, not just available.”); see id. at 88:18–89:18, 90:5–91:1. We further credit the testimony of Patent Owner’s declarant, Dr. Shenoy, who testified that Carter discloses “determin[ing] the free volume space available for allocation.” See Ex. 1144, 142:19–20 (referencing Ex. 1140, 19:14–17). Reading directly from Carter, Dr. Shenoy further testified that Carter discloses “request[ing] the total available space information and us[ing] this information to quickly determine whether to proceed with the allocation processing.” Id. at 142:14–17, 143:1617. In view of the explicit disclosure of Carter and the testimony of both declarants, we find that Carter’s controller performs an “assessment” in order to “determine the availability of resources.” Additionally, Carter states that policy controller 290 “can employ any of the suitable heuristics to direct the elements, such as the paging controller, disk directory manager, and other elements to dynamically distribute the available resources.” Ex. 1140, 36:29–37:2. Thus, we agree with Petitioner’s argument, as supported by the testimony of Dr. Kubiatowicz, that policy element 290 assesses the unused or underused storage resources when it determines the availability of such resources and uses some heuristics when distributing those resources that were assessed. See Pet 39 (citing Ex. 1102 ¶ 118). Accordingly, based on the entirety of the record before us, we find Petitioner has shown by a preponderance of the evidence that Carter discloses the “assessing” limitations of claims 1 and 13.” slip op. at 31

      “We agree with Patent Owner that Petitioner fails to offer sufficient explanation as to why a person of ordinary skill in the art would have combined the teachings of Carter and Condor. Rather, Petitioner appears to argue that, based on the advantages described by Condor (Ex. 1017, 5), and using well-known techniques with unspecified predictable results, a person of ordinary skill in the art would have had sufficient reason to combine these disparate elements taught in the prior art references to render the challenged claims obvious. Pet. 61–66. Yet, other than Petitioner’s cursory assertion of “advantageously incorporat[ing] the central coordinator in Condor to provide a centralized mechanism to manage resource sharing” (Pet. 66), which cites equally cursory and unsupported testimony by Dr. Kubiatowicz (Ex. 1102 ¶ 199), Petitioner fails to identify what particular advantages or efficiencies would have prompted a person of ordinary skill in the art to combine Condor’s scheduler with Carter’s system. Furthermore, Dr. Kubiatowicz’s testimony regarding predictable results and obviousness to try are similarly lacking in elaboration and substantiation. See Ex. 1102 ¶¶ 200–201. Such conclusory statements and unspecific testimony without evidence on the record cannot satisfy the Petitioner’s burden of demonstrating obviousness. In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); I/P Engine, Inc. v. AOL Inc., 576 F. App’x 982, 999 (Fed.

VGO Commc’ns, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014) (holding that expert’s testimony could not support a finding of obviousness where “testimony primarily consisted of conclusory references to [the expert’s] belief that one of ordinary skill in the art could combine these references, not that they would have been motivated to do so”); see also 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.”). Although Petitioner has not provided a sufficient rationale to combine in this asserted ground of unpatentability, Petitioner has otherwise demonstrated that claims 4, 6, 16, and 18 are unpatentable under 35 U.S.C. § 102(b) because they are anticipated by Carter. Petitioner, however, has not asserted claims 7 and 19 are unpatentable under any other ground in this proceeding. Therefore, we determine Petitioner has failed to establish by a preponderance of the evidence that claims 7 and 19 of the ’827 patent are unpatentable under 35 U.S.C. § 103(a) in view of Carter and Condor.” slip op. at 59
