      “proposed combination of Leaning and Gamble teaches all limitations of claims 2 and 9. I find that the added analysis for these claims based on Gamble overcomes the deficiencies in the other ground, including those of the base claim from which they depend. I also differ from my colleagues in how I view secondary considerations of nonobviousness. I find that the developed record of this case does not support that multiple TCP connections or multiple, parallel/simultaneous TCP connections are critical, unclaimed features of the ’772 patent. Indeed, Petitioner does not argue as much, and all challenged claims at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet. Reply 21–22) that Patent Owner cannot credibly maintain that it is entitled to a presumption of nexus to the same products— the MOVE Media Player and “Sling TV”—across nine patents and 120 claims having different scope while citing to substantially the same alleged evidence of secondary considerations. The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances. In addition, Patent Owner’s own cited evidence suggests that MOVE’s plug-in is a “key” feature of its technology, particularly to ensure “fluidity of playback” (PO Resp. 51–52 (quoting Ex. 2048) (emphasis omitted)), but the claims do not recite a plug-in. This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims. I also agree that Patent Owner’s evidence of secondary considerations is entitled to insignificant weight, or little to no weight, and that it does not outweigh Petitioner’s persuasive obviousness showing under the other Graham factors. Thus, I join in my colleagues’ determination that Petitioner has shown, by a preponderance of the evidence, that claims 2 and 9 would have been obvious over the combination of Leaning and Gamble.” slip op. at 101

      “generally known in the art, and that this is acknowledged by the ’853 patent. Pet. 40–41 (citing, e.g., Ex. 1001, 15:40–44). Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

      “In an inter partes review, the burden of persuasion is on the petitioner to prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e), and that burden never shifts to the patentee.” In re Magnum Oil Tools Int’l Ltd., 829 F.3d 1364, 1375 (Fed. Cir. 2016) (quoting Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015)); see also Aqua Products, Inc. v. Matal, 872 F.3d 1290, 1306 (Fed. Cir. 2017 (en banc (quoting Magnum Oil)). A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious to a person of ordinary skill in the art at the time the invention was made. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007) (quoting 35 U.S.C. § 103(a)). Obviousness is resolved based on 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, i.e., secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17– 18 (1966). A party who petitions the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v. Teva Pharms. USA, Inc., 566 F.3d 989, 994 (Fed. Cir. 2009) (quoting Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1361 (Fed. Cir. 2007)). We assess Petitioner’s evidence and argument according to the above- referenced obviousness standard. We determine that the Petition satisfies the reasonable likelihood of prevailing standard under 35 U.S.C. § 314(a).

      “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.

      “Petitioner relies on the ordinary and customary meaning of the claim terms consistent with the Phillips standard. Pet. 12–13 (citing 37 C.F.R. § 42.100(b)). The Petition addresses the construction of “peer-to-peer architecture” recited in independent claims 1 and 30 of the ’034 patent, a limitation we need not construe to decide the institution question. Id. at 13; Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Patent Owner contends that “no claim construction is required” to address the Petition’s asserted deficiencies. Prelim. Resp. 6. Patent Owner also contends, however, that the Petition relies on a “novel claim construction” of limitations [1.4.1] and [1.5.1]—“second [third] hardware processor with a plurality of processing cores”—to support Petitioner’s obviousness argument. Id. at 11–12.8 Patent Owner challenges the Petition’s reliance on “single core processors on different chips,” such as the Power3 single-core processors of the Symmetric Multi- Processor (“SMP”) configuration disclosed in the RS6000 reference, as a disclosure of limitations [1.4.1] and [1.5.1]. Id. Patent Owner contends that such single-core processors on different chips do not satisfy limitations [1.4.1] and [1.5.1] because the ’034 patent “claims only multicore processors.” Prelim. Resp. 5 (citing Ex. 1001, 7:15–27). Petitioner responds in part as follows: To the extent PO is implicitly arguing that RS6000’s “four, eight, twelve, or sixteen 375 MHz 630FP 64-bit processors” do not teach the recited “cores,” Patent Owner’s argument excludes embodiments described in the ’034 patent’s specification. The ’034 patent describes “[p]rocessor cores [as] generally independent microprocessors.” Ex.1001, 5:14–15. Patent Owner’s attempt to exclude RS6000 from the scope of the claims 8 Pursuant to the Board’s Order on Related Matter Updates (Paper 14), the parties filed the September 26, 2025 Claim Construction Order entered in the co-pending District Court litigation in this proceeding. Ex. 1085. The District Court Claim Construction Order did not construe the claim phrase “hardware processor with a plurality of processing cores.” Id. patent where the processor has independent microprocessors. Patent Owner’s attempt to distinguish RS6000’s Symmetric MultiProcessor as a “configuration” (Paper 8, 24) also fails because a “Symmetric MultiProcessor configuration” is no different than the ’034 patent’s description of a configuration of independent microprocessors. Id. Paper 9, 30.9 It is apparent there is a dispute over the plain meaning of Limitations [1.4.1] and [1.5.1], “a second [third] hardware processor with a plurality of processing cores,” recited in the independent claims.10 The parties are ordered to propose and support a particularized plain meaning or other construction of Limitations [1.4.1], [1.5.1], and [30.1.2] in their briefs. The parties are ordered to analyze the relevant claim language and cite to the specification and prosecution history in support of their claim construction, where applicable, with particular attention to the description of a hardware processor with a plurality of processing cores in the ’034 patent.
