“Petitioner argues that a person of ordinary skill in the art “would have had . . . a bachelor’s degree in electrical engineering, microelectronics, or equivalent and . . . two to three years of industry or research experience in the field of wireless energy transfer,” and that “a higher level of education or skill might make up for less experience, and vice-versa.” Pet. 6 (citing Ex. 1003 ¶¶ 39–44).

“spaced configuration are not confined to ferrite cores 32 and 3, and that at least a component of the flux lines will escape the cores. See Ex. 1032 ¶¶ 48–52; Ex. 1038 ¶ 54 Fig. 2. Indeed, the evidence suggests (and Dr. Horenstein acknowledges in his first declaration) that at least a component of flux will escape the core of even a traditional transformer. See Ex. 1032 ¶¶ 45–47; Ex. 1044, 6; Ex. 2001 ¶ 27. In his second declaration, Dr. Horenstein provides contrary testimony that in Odachi’s open configuration during alignment, cores 32 and 3 “act to confine or guide the magnetic flux lines, rather than radiate them into free space,” and “the flux lines would [not] leave the gap area and enter into the space distal to the magnetic circuit.” Ex. 2010 ¶ 69. But in view of Dr. Horenstein’s contrary position in his first declaration, and the lack of supporting evidence in his second, we do not find it credible. 37 C.F.R. § 42.65(a) (2022) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Apple Inc. v.

“(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31. See Ex. 2006, 498; Ex. 1045, 5:4–7; Ex. 1032 ¶¶ 53–54). Dr. Horenstein’s testimony does not contradict this. Although he points out that there are separate terms for inductive, near, and far fields, he also acknowledges that “[t]he region of space closer to the antenna than the far field is the near-field region.” Ex. 2010 ¶ 37 (citing Ex. 2006, 275).8” slip op. at 22

Mr. Wechselberger explains that an ordinarily skilled artisan would have recognized the importance of identifiers “to differentiate amongst keys, and that providing unique values (such as key numbers) to keys would ensure that the system does not confuse keys.” Id. ¶ 153.

At this stage of the proceeding, and crediting the testimony of Mr. Wechselberger, we are persuaded that the combined teachings of Peterka and Suzuki would have allowed a person of ordinary skill in the art “to ‘eliminat[e] the confirmation delay’ during key changes, and realize Peterka’s embodiment where “each client keeps track of the keys and their expiration times and actively requests new keys before the current keys expire so as to avoid service interruptions.” See Ex. 1006 ¶ 11; Ex. 1005 ¶ 105.” slip op. at 30

“term “wicked into contact” that the Board adopted in a prior inter partes review proceeding that addressed the same term in an earlier, related patent. Pet. 7 (citing IPR2020-01602, Paper 32 at 8–15 (PTAB March 30, 2022)). ‘wicked into contact’ to mean: ‘wicked into contact (1) with the heater, or (2) with an area in close proximity to, and exposed [to] the heat produced by, the heater,’” and “[t]he present Petition adopts this formal construction for purposes of this IPR proceeding.” Id. (citing IPR2020-01602, Paper 32 at 15). Patent Owner also “adopts this construction for purposes of” the Preliminary Response, and argues that “Petitioner’s grounds fail even under its proposed construction of ‘wicked into contact.’” Prelim. Resp. 13. For purposes of this Decision, we adopt the Board’s prior construction of “wicked into contact,” namely, “wicked into contact (1) with the heater, or (2) with an area in close proximity to, and exposed to the heat produced by, the heater,” which is undisputed on this record.

“To establish anticipation, each and every element in a claim, arranged as recited in the claim, must be found in a single prior art reference. Net Karsten Mfg. Corp. v. Cleveland Golf Co., 242 F.3d 1376, 1383 (Fed. Cir. 2001). “A reference may anticipate inherently if a claim limitation that is not expressly disclosed is ‘necessarily present, or inherent, in the single anticipating reference.’” In re Montgomery, 677 F.3d 1375, 1379 (Fed. Cir. 2012) (quoting Verizon Servs. Corp. v. Fibernet Va., Inc., 602 F.3d 1325, 1336–37 (Fed. Cir. 2010)). Based on the current record, we are not persuaded that Petitioner sufficiently establishes that Morgan discloses “a storage compartment . . . being arranged such that the liquid aerosol-forming material can be wicked into contact with the electrical resistance heater to volatilize the liquid aerosol-forming material” as recited in claim 1.” slip op. at 12
