“These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions. In fact, neither does Patent Owner’s witness, Mr. Leinsing, who states that his “opinions would not change under either definition.” Ex. 2011 ¶ 40.

“Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). That does not appear to be the case here—the present record does not support that the described asymmetrical buttress, serrated style of different temporary screw threading (relative to that of the definitive screw and regardless of the direction of the threads for rotation) is sufficiently representative of the genus’s “different” thread patterns/profiles. See, e.g., Ex. 1006 (a buttress style thread does not function the same as a buttress reverse or 75º joint profile or rounded, or trapezoidal thread).” slip op. at 30

“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). We begin our analysis with a discussion of the Menon, Trefethen, RS6000, and POEref references. slip op. at 15

“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. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). “These factors are not exhaustive but are merely a Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). There is uncontested evidence in the record before us that reflects the knowledge and experience of a POSITA. For purposes of this Decision, we adopt the Petition’s formulation of the level of ordinary skill in the art, which is consistent with the description in the ’034 patent, the prior art of record, and the testimony of both experts.” slip op. at 11

“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. See, e.g., Ex. 1001, 5:11–37, 7:14–36, 9:50–10:3.” slip op. at 12

“Motivation to Combine and Analogous Art The Petition offers several motivations to combine Menon, Trefethen, RS6000, and POEref in the manner claimed in the ’034 patent with a reasonable expectation of success, which we find sufficient on the present record. The Petition first asserts that Menon and Trefethen are analogous prior art because they pertain to the same “field of cluster computing” as the ’034 patent and “are reasonably pertinent to the problem of the ’034 patent, namely, executing a single program on multiple nodes.” Pet. 22 (citing Ex.1001, 1:14–15; Ex.1003, ¶¶ 65–69; Ex. 1005, 2; Ex. 1006, Abstract). The Petition points out that Menon expressly cites and builds on the MultiMATLAB system taught by Trefethen. Id. (citing Ex. 1003 ¶ 71; Ex. 1005, 1–2). The Petition also contends that: Accordingly, Menon and Trefethen together represent a combination of prior art elements according to known methods (executing MATLAB code on a multiprocessor system) to yield the predictable result discussed in both papers: the MultiMATLAB system executing MATLAB in parallel to perform mathematical calculations. Id. at 22–23 (citing Ex. 1003 ¶ 70; Ex.1005, Abstract; Ex. 1006, 2–7). The Petition further contends that a POSITA would have found it predictable to combine Trefethen with Menon with a reasonable expectation of success” slip op. at 20

Even if we were to agree with Petitioner that a user could download and store selection pages to the local device, such downloading and storing must occur before the user locally performs a preliminary search in order for the selection pages to be “beforehand locally stored” within the scope of claims 1 and 27.
