Claims 1–5, 8–12, and 15–19 were not shown unpatentable because Petitioner did not sufficiently show that Agee alone or with Butler teaches the claimed signal information and weighting-value determinations.

“including the design of beamforming using multiple antennas.” Pet. 6. Petitioner contends that a person having ordinary skill in the art would have at least a Bachelor’s degree in Electrical Engineering or equivalent, and at least two years of work experience. Id. at 6–7. Petitioner adds that “[a] more advanced degree can substitute for some work experience.” Id. at 7 (referencing Ex. 1003 ¶¶ 37–39). Patent Owner does not challenge Petitioner’s proposed definition. PO Resp. 8. In our Institution Decision, we adopted Petitioner’s proposed definition, finding it to be consistent with the prior art of record and the skill reflected in the Specification of the ’235 patent, and previous proceedings concerning the ’235 patent.

“C. Claim Construction The parties agree that the claims of the ’235 patent should be given their plain and ordinary meaning. Pet. 6; PO Resp. 8. Patent Owner also provides claim constructions adopted in related district court litigations for certain terms. PO Resp. 9–10.

“each antenna” and “Agee’s Butler matrix measures a different signal strength for each of the 32 OFDM tones (channels) on each antenna” (Pet. 62), Agee does not describe that its Butler Forming Mode circuitry determines (or measures) signal strength. Rather, Petitioner relies on unsupported testimony from Dr. Mahon. Pet. 61 (citing Ex. 1003 ¶¶ 513– 536). Although Dr. Mahon affirmatively states that Agee discloses measuring the “signal strength” for limitations [1.4] and [1.5], he only quotes Agee’s column 45, lines 4–28 to conclude that “such measurements are detecting and processing the signal strength in the passages regarding the OFDM vector receiver receiving and detecting data induced on each antenna.” Ex. 1003 ¶ 524. However, the testimony provides no further explanation as to why this is the case other than quoting the paragraph. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Agee is not self-explanatory on this point. See Personal Web Techs., LLC v. Apple, Inc., 848 F.3d 987, 994 (Fed. Cir. 2017). Consequently, assessing the probative value of the testimony, we find that the bare, unintelligible statements regarding Agee and how it allegedly teaches “signal strength” are entitled to little weight.14 14 We recognize that at the Decision on Institution stage, the panel credited Dr. Mahon’s testimony with respect to how the Butler matrix detects different phased signals at the antenna for limitations [1.3]−[1.5]. Inst. Dec. 24–28. Upon review of the full record, and in consideration of the preponderance of the evidence standard, however, we no longer view the testimony sufficiently supported. The “Board has an obligation to assess the question anew after trial based on a totality of the record, particularly where Further, it is unclear from both Petitioner’s contentions and Dr. Mahon’s testimony whether Petitioner is arguing that such functionality is inherent in Agee’s Butler matrix, common knowledge, how a person of ordinary skill in the art would understand Agee in light of general Butler matrix functionality, or something else entirely. See Netflix, 84 F.4th at 1377 (stating that “the Board should . . . not have to decode a petition to locate additional arguments beyond the ones clearly made”). Petitioner also does not provide sufficient support for these contentions from Butler. In sum, Petitioner relies on Dr. Mahon’s testimony for the contentions in limitations [1.4] and [1.5], at least with regard to determining “signal strength” as the recited determining first and second “signal information.” As explained in our Consolidated Trial Practice Guide15 (Nov. 2019) at 36: Expert testimony, however, cannot take the place of a disclosure in a prior art reference, when that disclosure is required as part of the unpatentability analysis . . . Similarly, in an obviousness analysis, conclusory assertions from a third party about general knowledge in the art cannot, without supporting evidence of record, supply a limitation that is not evidently and indisputably within the common knowledge of those skilled in the art. K/S Himpp v. Hear-Wear Techs., LLC, 751 F.3d 1362, 1365 (Fed. Cir. 2014). Furthermore, because an inter partes review may only be requested “on the basis of prior art consisting of patents or printed publications,” 35 the standard changes.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1377 (Fed. Cir. 2016). “[T]he Board is not bound by any findings made in its Institution Decision. At that point, the Board is considering the matter preliminarily without the benefit of a full record. The Board is free to change its view of the merits after further development of the record, and should do so if convinced its initial inclinations were wrong.” TriVascular, 812 F.3d at 1068. 15 Available at https://www.uspto.gov/sites/default/files/documents/ tpgnov.pdf U.S.C. § 311(b), expert testimony cannot take the place of disclosure from patents or printed publications. In other words, expert testimony may explain “patents and printed publications,” but is not a substitute for disclosure in a prior art reference itself.” slip op. at 26

“To that end, we find Petitioner’s contentions and evidence are insufficient as to limitations [1.4] and [1.5]. However, even assuming, arguendo, that Petitioner’s reliance on Dr. Mahon’s testimony is sufficient to show that limitations [1.4] and [1.5] are taught by Agee, i.e., that it is “evidently and indisputably within the common knowledge of those skilled in the art,” Petitioner still must show that the set of weighting values is determined based upon the signal strength, as recited in limitation [1.6]. As we discuss below, Petitioner’s contentions and evidence are insufficient for limitation [1.6].” slip op. at 28

“In considering the “appropriate weight” to give a prior construction we look at “the similarities between the record in the district court or the ITC and the record before the Board”; “whether the prior claim construction is final or interlocutory”; “whether the terms construed by the district court or ITC are necessary to deciding the issues before it”; and “the facts and circumstances of each case.” Patent Trial and Appeal Board Consolidated Trial Practice Guide at 47 (Nov. 2019), https://www.uspto.gov/sites/default/ files/documents/tpgnov.pdf. The briefing of the parties in the District Court suggests the evidence was substantially the same as here. See, e.g., Ex. 1056,8 14–17 (citing Shpak (Ex. 1005 here); Geier Declaration (Ex. 2005 here); Ex. 10589). The District Court’s Claim Construction Order states the construction is “final.” See Ex. 1055, 1 (“final construction”). Trial was set 8 ’632 Lawsuit, Plaintiffs’ Opening Claim Construction Brief, Dkt. 37. 9 ’632 Lawsuit, Transcript of Markman Hearing, February 4, 2021. for January 10, 2022, but the case was reassigned and an Order Resetting Schedule entered January 12, 2022, setting a pretrial for May 19, 2022, and a jury trial for June 13, 2022. ’632 Lawsuit, ECF No. 89; see also Inst. Dec. 42 (ordering the parties to advise us of “the setting of a trial date”). The construction could change as the record is further developed at trial. As to the necessity for construction, the District Court did construe “mandatory channel.” We disagree with Petitioner that the District Court “explicitly rejected [Patent Owner’s] contention that ‘mandatory channel’ limits the claims to multichannel systems.” Reply 19 (citing Ex. 1056, 14–17; Ex. 1057,10 7–9; Ex. 1058, 21:3–30:24); see Section III.C.1.c below.
