      “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Upon consideration of the arguments and evidence presented by Petitioner and Patent Owner, we are persuaded that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing the unpatentability of at least one of the challenged claims. See 35 U.S.C. § 314(a). Accordingly, we institute an inter partes review of the challenged claims. slip op. at 2

      “Patent Owner does not dispute Petitioner’s proposed level of ordinary skill in the art stating that “[f]or the purposes of this Preliminary Response only, Patent Owner utilizes Petitioner’s proposed level of skill in the art.” Prelim. Resp. 2. On this record, Petitioner’s proposed level of ordinary skill in the art is not disputed and is consistent with our review and understanding of the technology and descriptions in the ’767 patent and the asserted prior art references. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this Decision, we rely on Petitioner’s proposed level of ordinary skill in the art.” slip op. at 9

Patent Owner does not dispute the construction of these terms, stating only “that claim construction is not required to resolve any issues.” PO Resp. 2 (citing Pet. 18–20). Where there is no dispute and our Decision does not turn on any particular construction of these terms, we need not decide at this point whether “receiver module” and “transmitter module” invoke means-plus-function under 112(f).

And, because there is no dispute, we conclude that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding.

Petitioner relies on Kalili as disclosing a hard layer suitable for combination with Tadros’s soft layers (Pet. 32), and more particularly, doing so in the context of a laminated multilayer aligner (Reply 4). To create the laminated multilayer aligner proposed, Petitioner’s suggested use of a particular type of well-known lamination, i.e. adhesive lamination, is sufficiently developed and supported in the Petition. Pet. 32–35. Here, Patent Owner recognizes that Kalili teaches lamination, but suggests that it does not specifically teach using adhesive lamination. Prelim. Sur-reply 5.

      “IV. CONCLUSION At this stage of the proceeding, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenges as to at least one challenged claim. At this preliminary stage, we have not made a final determination as to the patentability of the challenged claims or any underlying factual and legal issues. V. 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

      “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

See, e.g., Ex. 1001, 1:14–62. Because we discern no dispositive difference between the parties’ proposals, and neither party has argued that the choice between the two would affect the outcome,6 we adopt Petitioner’s proposed level of skill for this decision.
