      “Paper 34, 1 (requesting “Director Review of the Director’s August 22, 2025 Decision Referring the Petition to the Board (‘Referral Decision’)”). Patent Owner argued that institution of IPR2025-00687 and IPR2025-00688 “should be discretionarily denied.” Id. at 5. Petitioner opposed. Paper 37. The Director granted review and found that “granting institution of two petitions that each challenge the same claims of the ’370 patent and ’218 patent 2” was an “abuse[] of discretion.” Paper 40, 1. The Director remanded the cases “to the Board panel to determine which of the two petitions challenging each of the ’370 and ’218 patents to institute.” Id. at 3. Pursuant to the Director’s instruction that we choose only one of the two petitions challenging the ’370 patent to institute, and for the reasons set forth below, we choose to institute review of the ’370 patent in this Petition, and not in IPR2025-00688.” slip op. at 3

      “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); 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 demonstrates a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’110 patent.

ORDER It is, therefore, ORDERED that, pursuant to 35 U.S.C. § 314(a), an inter partes review of all challenged claims of the ’113 patent is instituted with respect to all challenges of unpatentability set forth in the Petition; and FURTHER ORDERED that pursuant to 35 U.S.C. § 314(c) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial commencing on the entry date of this Decision.” slip op. at 18

      “measurement value, as Jover teaches.” Id. (citing Ex. 1005 ¶¶ 39–40; Ex. 1003 ¶¶ 115–30). Among other reasons, Petitioner contends that a POSITA would have been motivated to combine “to improve the accuracy and reliability of the beam failure determination.” Id. at 37 (citing Ex. 1003 ¶¶ 115–30). Petitioner further contends that a POSITA would have had a reasonable expectation of success because “it would have been straightforward for a POSITA to implement Jover’s triggering condition in Xia’s method.” Id. at 38 (citing Ex. 1003 ¶¶ 115–30). After considering Patent Owner’s arguments, which we address below, we agree with Petitioner at this stage that the combination of Xia and Jover renders obvious limitation [1e]. Patent Owner first argues that Jover “does not cure the deficiencies of Xia because Jover’s threshold condition for an increase in BER is not used for triggering a transmission of the first and second radio signal.” Prelim. Resp. 20. Just like Xia, Patent Owner contends, Jover discloses no “causality between the threshold being exceeded and transmitting the first and second radio signal.” Id. at 21. This argument does not undermine Petitioner’s showing at this stage because Petitioner relies on Xia, not Jover, for the claimed “triggering the transmission,” or “causality,” as Patent Owner calls it. See Pet. 36–38. That is, Petitioner relies on Jover for the triggering condition and on Xia for the actual triggering. See id. Patent Owner’s argument attacking the references individually is unpersuasive. See In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of refences.”). Patent Owner next contends that one of ordinary skill in the art would not have combined Xia and Jover “since Jover is directed to the opposite objective of the ’113 Patent or Xia.” Prelim. Resp. 21. That is, Patent Owner asserts, Jover teaches away from the disclosed methods. Id. at 22. Patent Owner explains, “Jover provides no attempt to improve the beam strength, but rather ignores it through beam sweeping or nullif[ies] it, in contrast to the purpose of the ’113 Patent.” Id. at 22–23. At this stage, Patent Owner’s argument is insufficient to undermine” slip op. at 15

      “Pet. 4 (citing Ex. 1003 ¶¶ 10, 16, 29–32). Patent Owner uses Petitioner’s proposed level of skill in the art at this stage. Prelim. Resp. 6. We are persuaded, on the present record, that Petitioner’s proposal is consistent with the problems and solutions in the ’271 patent and prior art of record. We adopt Petitioner’s definition of the level of skill at this stage.” slip op. at 6

      “The parties do not propose any explicit claim constructions. See Pet. 4–6; Prelim. Resp. 6. As no terms are in dispute, we do not construe any terms. Petitioner discusses constructions proposed by Patent Owner in the Samsung IPR, but Patent Owner does not rely on those constructions here. Pet. 4–6 (citing IPR2023-00747, Paper 14 at 11–13). We therefore do not address them at this stage.” slip op. at 6

      “discloses the claimed “proportional sequence.” Prelim. Resp. 9. First, Patent Owner contends that “indexes of antenna port groups with RSRP measurement values higher than a certain threshold are not a sequence of ratios,” but rather, just an identification of antenna port groups. Id. (emphasis added). We disagree, on this record. The flaw in this reasoning is that the claim does not require the first proportional sequence to be a sequence of ratios. Rather, the claimed “first proportional sequence” merely “corresponds to . . . ratios.” Thus, Patent Owner’s argument that the indexes “are not a sequence of ratios” is not commensurate with the scope of the claim. Petitioner persuades us, at this stage, that the indexes correspond to ratios (e.g., RSRP_n/max(RSRP_i)). See Pet. 32–33.” slip op. at 7

      “Under 35 U.S.C. § 314(a), inter partes review may not be instituted unless the Petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Petitioner has established a reasonable likelihood of prevailing on at least one challenged claim is unpatentable. Thus, for reasons explained below, we institute inter partes review of claims 1–14 of the ’445 patent.” slip op. at 2

      “Ex. 1002 ¶¶ 30–34). Petitioner asserts that the POSA’s education “could include a bachelor’s degree in business or economics, with an emphasis on the use of technology in marketing or advertising” or “similar knowledge gained through actual work experience.” Id. Alternatively, the POSA’s education could include “a bachelor’s degree in computer science or equivalent industry experience, and work with a team that includes software engineers.” Id. According to Petitioner, the POSA “could also have qualified with more formal education and less technical experience, or vice versa.” Id. Petitioner’s definition appears to be consistent with the field of the invention reflected in the prior art of record and the disclosure of the ’445 patent. Accordingly, for purposes of this Decision, we adopt Petitioner’s proposed definition of the person of ordinary skill in the art.” slip op. at 8

      “C. Claim Construction We interpret a claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b) (2020). Under this standard, we construe the claim “in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. Petitioner “applies plain-and-ordinary meaning to all terms.” Pet. 20. We determine that no terms require express construction at this stage. See Realtime Data, LLC v. Iancu, 912 F.3d 1368 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, 8 and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

      “Petitioner recognizes that the combination of Gilmour and Merriman alone “does not disclose that the profile owner computer automatically 17 selects a media property entity of a plurality of media property entities based on a comparison of the profile information with a plurality of stored requests from the plurality of media property entities.” Id. at 42. To address this deficiency, Petitioner asserts that Frauenhofer “discloses automatically selecting a user of a plurality of users based on a comparison of content with the plurality of stored requests from the users.” Pet. 44 (citing Ex. 1014, 3:12–19). Petitioner argues that it would have been obvious to combine Frauenhofer’s teachings with those of Gilmour and Merriman to arrive at the claimed method. Id. According to Petitioner a POSA “would have been motivated to make this combination because it would conveniently allow Gilmour’s requesting entities (which are media property entities) to make initial requests to the profile service provider, and then automatically receive profiles matching the requests on an ongoing or periodic basis.” Id. at 45. (citing Ex. 1010, 41; Ex. 1011, 39–40, 51; Ex. 1012 ¶ 25; Ex. 1013, 3:20– 23; Ex. 1002 ¶ 155).” slip op. at 17
