      “institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2020); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented shows a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’027 patent. Accordingly, we institute an inter partes review of all challenged claims (i.e., 1–3, 5, 7–9, 11–13, and 15–22) of the ’027 patent, based on the grounds asserted in the Petition.” slip op. at 2

      “We disagree with Patent Owner’s contentions that these disclosures indicate that Wilson’s patch would not meet the construction of “barrier material composition.” None of these disclosures even suggests that the base of Wilson’s patch is rigid as Patent Owner suggests. To begin with, the fact that the housing is “more rigid” provides no information about the absolute rigidness of the patch. See Ex. 1009, 9:16–21. As for the disclosure that the patch is contoured (id. at 3:35–67), Patent Owner provides only attorney argument to support its contention that the contour demonstrates that Wilson’s patch must be so rigid that it cannot be meet the claim limitation. In contrast, Petitioner demonstrates that Wilson discloses using the exact same materials described in the challenged patent (see Ex. 1001, 6:33–58 (noting “[e]lastomeric materials useful for forming the intermediate layer 24 include but are not limited to gum rubber, vulcanized natural rubber SBR . . . or comparable materials”); Ex. 1009, 3:49–55 (noting the patch may be constructed from natural rubber (NR), a preferred mixture of chlorobutyl rubber and natural rubber (CR/NR), or a preferred mixture of SBR and natural rubber (SBR/NR)), and provides detailed testimony from its expert to support its contentions (see Ex. 1003 ¶¶ 114–119). On the current record, we find Petitioner’s reasoning and evidence to be persuasive, and find that Petitioner has shown sufficiently that Willson discloses or teaches this limitation.” slip op. at 20

Patent Owner contends that an ordinarily skilled artisan “would have [had] a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent degree and, in addition, approximately two years of work experience with Internet video streaming, Internet communication, and related protocols.” Prelim. Resp. 20–21 (citing Ex. 2001 § IV.C). The differences between the parties’ definitions are minor, as recognized by Dr. Rubin (see Ex. 2001 ¶ 104), and we do not discern any meaningful differences based on the preliminary record. Accordingly, for purposes of this Decision, we adopt Patent Owner’s definition of the level of ordinary skill in the art. On the present record, we are satisfied that this definition of the level of skill is consistent with the teachings of the ’088 patent and the asserted prior art. Notwithstanding, we would reach the same determination under Petitioner’s formulation of the level of skill.” slip op. at 10

      “For purposes of this Decision, we determine that no aspects of the challenged claims require explicit construction. See, e.g., Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundDecided for patent owner

      “obviousness contentions based on Ellis and Spivey rely expressly on the use of a “known webserver” to perform the “transmitting first instructions” limitations excerpted above. See Pet. 28–34. Yet Petitioner does not specify how such a webserver would be integrated with the other elements from Ellis and Spivey cited by Petitioner. At best, Petitioner provides a background section on the known use of webservers (see id. at 11 (citing Ex. 1001 ¶¶ 49–53, 127–134)), but this does not provide a rationale for integrating a webserver in the Ellis–Spivey combination. We also have considered Petitioner’s cited testimony from Dr. Wicker supporting this background section. The first cited portion, which is located at paragraphs 49–53 of Dr. Wicker’s declaration, supports the premises in the background section, but does not include a rationale for adding a webserver to the Ellis– Spivey combination. See Ex. 1001 ¶¶ 49–53. The second cited portion, which is located at paragraphs 127–134 of Dr. Wicker’s declaration, includes a rationale for modifying the Ellis–Spivey combination to include a webserver.3 See Ex. 1001 ¶¶ 127–134. But that rationale is completely 3 The cited rationale in Dr. Wicker’s declaration appears to be tailored to support Petitioner’s obviousness contentions in IPR2025-00251, where unaddressed in the Petition. We decline to assume that Petitioner adopts Dr. Wicker’s testimony about the rationale as its position, because that would amount to improper incorporation by reference under 37 C.F.R. § 42.6(a)(3). See Patent Trial and Appeal Board Consolidated Trial Practice Guide at 35–36 (Nov. 2019), available at https://www.uspto.gov/sites/ default/files/documents/tpgnov.pdf (citing Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454 (PTAB Aug. 29, 2014) (Paper 12) (informative)) (stating that “parties that incorporate expert testimony by reference in their petitions, motions, or replies without providing explanation of such testimony risk having the testimony not considered by the Board”).” slip op. at 18
