“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. Osseo Imaging, LLC v.

“C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

“Additionally, we credit the testimony of Dr. Almeroth, who opines that Kleve discloses that certain restrictions are sent with the request to generate a virtual key. Ex. 1003 ¶¶ 118–123. Specifically, Dr. Almeroth testifies that Kleve discloses that the virtual key “enable[s] the keyless drive system for the appropriate Temporary User during a given rental period.” Id. According to Dr. Almeroth, this “indicates that rental agreement restrictions were sent with the request so that the virtual key could be associated with said restrictions.” Id. (citing Ex. 1004 ¶¶ 39, 68 (“Once the rental period has expired the virtual key may be reset and cleared from the VCS.”)). Dr. Almeroth further testifies that the virtual key in Kleve is always generated after the rental agreement. Id. (citing Ex. 1004 ¶¶ 39 (“[O]nce the Temporary User selects the vehicle, pays the appropriate amount and signs a consent agreement, th[e]n the system may generate a virtual key to distribute to the Temporary User and VCS.”), 68). We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing Ex. 2030, 27:5–10, 27:21–28:1). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2030, 26:14–20. Then the following exchange occurs: Q. So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don't know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s always the case. That might be a pretty common scenario, but I don't know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2001 ¶¶ 56–57. Therefore, we do not credit or agree with Dr. Malek’s testimony that Kleve teaches away from the concept of a virtual key created with the agreed-upon rental period as a restriction.

Patent Owner also relies on dependent claim 2, which depends from independent claim 1. PO Resp. 28–29. Dependent claim 2 adds to claim 1 the requirement that the driver be configured to increase and decrease the transmission frequency when a particular signal is received. See Ex. 1001, 28:47–54. Patent Owner asserts that this means that the driver is configured to increase/decrease the “substantially different” frequency, namely a frequency that lies within the near-linear region of a frequency-amplitude graph, and argues that, “[i]n reading claim 2 as a whole, a POSITA would understand that the ’696 Patent is directed to a linear control technique for predictably regulating power transfer.” PO Resp. 28–29 (citing Ex. 2006 ¶ 101). Even if dependent claim 2 called for linear control as Patent Owner appears to assert, we would not read such a limitation into the underlying independent claim. See Karlin Tech., Inc. v.

Dr. Woods, in support of his opinion, notes that Onishi’s legend for Figure 4 describes f0 as the “RESONANCE FREQUENCY IN LOAD-CONNECTED STATE.” Id. We find Dr. Woods’s testimony more credible than Dr. Mercier’s. We disagree with Patent Owner’s argument (PO Resp. 35) that Petitioner’s reliance on Onishi’s Figure 4 is misplaced, and we find that Figure 4 discloses a resonant frequency of the inductive couple between the primary and secondary coils, as recited in limitations 1.4 and 1.7.” slip op. at 32

“We do not find Patent Owner’s arguments persuasive. We agree with Petitioner that Patent Owner’s arguments are incorrectly premised on a hypothetical combination involving the bodily incorporation of the two references’ specific structures. See Pet. Reply 17. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also In re Sneed, 710 F.2d 1544, 1550 (Fed.

Rather, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR Int’l Co., 550 U.S. at 417. Petitioner’s proposed combination is the application, to Onishi’s charging system, of Flowerdew’s general teaching of the technique of using an alignment mechanism in order to optimize the alignment of the inductive coils and to maximize the inductive coupling. See, e.g., Pet. 15 (“[A] POSITA would have been motivated to implement Onishi in a manner that includes an alignment mechanism as suggested by Flowerdew (e.g., a dished recess or other shaped surface feature, a directional logo/marker, or both) so that the primary and secondary coils would be more readily ‘optimized’ for alignment and the inductive ‘coupling is maximized.’”). Flowerdew teaches, for example, that, with the use of a dished charging surface, the secondary unit “tends to align in one axis” and “[t]his alignment is such that the coupling between a solenoid receive coil in secondary unit 304 and the charging coils of charger 302 is maximized.” Ex. 1005, 11:25–52. Petitioner, with the supporting testimony of Dr. Woods, contends, and we agree, that a person of ordinary skill in the art “would have been sufficiently skilled to implement [the proposed] combination given the predictable techniques disclosed in each reference and the relatively advanced state of the art at the time.” Id. at 17 (citing Ex. 1003 ¶ 55). We determine that Petitioner has shown that the proposed combination teaches or suggests the subject matter of limitation 1.3 and that Petitioner has set forth adequate and persuasive reasons with rational underpinning as to why a person of ordinary skill in the art would have modified Onishi’s system to utilize an alignment mechanism. We also determine, for the reasons stated by Petitioner, that a person of ordinary skill in the art would have had a reasonable expectation of success in making the proposed combination.

“These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions.

“Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v.

“We note that the identification of a Ph.D. as an example of “more formal education” creates a vast range of education relative to a bachelor’s degree. Thus, we treat the identification of a Ph.D. just as it is—an example—and not a requirement. In this case, “more formal education” can be satisfied by a level of education less than a Ph.D (but greater than a bachelor’s degree). Based on our review of the record before us, we determine that Petitioner’s stated level of ordinary skill in the art is reasonable because it appears consistent with the evidence of record, including the asserted prior art. Accordingly, we adopt Petitioner’s definition, limited as discussed above, for the purposes of this Decision.” slip op. at 15

“Petitioner argues that one of ordinary skill in the art would have found the proposed modification obvious for several reasons. Pet. 30. For instance, Petitioner argues that “Unger contains an express teaching, suggestion and/or motivation to incorporate an element such as Smith’s torsional spring into the lower and/or upper mount assemblies 308, 312 to facilitate attachment and detachment.” Id. Namely, Petitioner points to Unger’s disclosure that device mounts 308, 312 may be flexible or resilient so that device mounts 308, 312 may be bent to engage a portion of hearing protection device 108 and are then allowed to return to a normal state to secure communication device 104 to hearing protection device 108. Id. at 30–31 (quoting Ex. 1004, 6:20–37). Petitioner adds that one of ordinary skill in the art would have understood this disclosure “to teach that mount arms 308, 312 could be removable from housing 304 (e.g., as mount arm 312 is in Figure 6) and/or they could be designed to be ‘flexible’ or ‘resilient’ such that they can be manipulated,” and “that ‘resilient’ is defined as ‘bouncing or springing back into shape, position, etc. after being stretched, bent, or, esp., compressed.’” Id. at 31 (citing Ex. 1002 ¶ 117). Thus, according to Petitioner, this disclosure of Unger suggests using a torsion spring. Id. In addition, Petitioner asserts that one of ordinary skill in the art would have understood Unger’s disclosure to “suggest the use of a torsion designed to impart this functionality.” Pet. 30 (citing Ex. 1002 ¶ 118). Petitioner also asserts that one of ordinary skill in the art would have “understood that there were a limited number of ways to impart the referenced resilient or flexible ‘manipulation,’” and “would have been motivated to look to various known solutions to impart the suggested functionality, including the torsional spring mechanism of Smith that is used in a similar hearing protection device application for a similar purpose as Unger’s mounting arms (to apply a clamping force).” Id. at 32 (citing Ex. 1002 ¶¶ 120–121). Other reasons for combining the references set forth by Petitioner are the proposed modification: (1) “would have involved applying a known technique to a known device ready for improvement to yield predictable results” (Pet. 39–49 (citing Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed. Cir. 2023); Ex. 1002 ¶ 131)), (2) would have constituted “combining prior art elements using known methods to achieve predictable results” (id. at 40 (citing KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007); Ex. 1002 ¶ 133)); and (3) would have been “the simple substitution of one known element (i.e., Smith’s torsion spring mechanism) into another (i.e., the connection point of Unger’s lower mount arm 308 and housing 304)” (id. at 40–41 (citing Apple Inc. v.

“On this record, it is not entirely clear that comparing a BSS color value to determine if a receiving station is in that BSS is prohibited by the claim’s recitation “not to use” a BSS color, as Patent Owner’s argument implies. Rather, claim 1’s recitation “not to use a Basic Service Set (BSS) color when signaling information indicates that an operation based on the BSS color is not allowed” appears directed to prohibiting a particular operation based on the BSS color, not necessarily disregarding the BSS color entirely. Further, comparing BSS values to determine BSS identity appears consistent with claim 1’s recitation that “the BSS color is an communication terminal recognizes that a BSS color collision has occurred.” On this record, it appears that BSS color would need to be identified to determine if a color collision occurs. See Prelim. Resp. 4 (“BSS color collisions occur when two or more BSSs operating on the same frequency channel (and overlapping in coverage area) use the same BSS color. See ’163 Patent at 2:46-59, 10:41-62. In other words, a wireless communication terminal receives a signal with the same BSS color that device understands applies to it, even though the signal is intended for another device in a different BSS (albeit using the same BSS color). When a color collision is detected, the wireless communication terminal reports to the base wireless communication terminal, which will indicate that a color collision has occurred. ’163 Patent at 3:16-20.”). In that light, we see some merit in Petitioner’s position that an “operation based on BSS COLOR (e.g., allowing access and re-using the channel) is not allowed” based on the Low Power/High Interference Indicator, even if some reference is made to the BSS color to resolve a condition precedent to that determination, namely whether the data are from a different BSS. See Pet. 53–54 (citing Ex. 1009 ¶ 26; Ex. 1003 ¶ 170). Petitioner’s second theory is based on setting the color field to a reserved value of “0000,” which Petitioner argues “indicates that operations based on BSS COLOR are not allowed and the receiving STA does not use BSS COLOR.” Pet. 54–55 (citing Ex. 1009 ¶¶ 25, 29; Ex. 1003 ¶ 172). On this record, we question how setting a color value to 0000 can teach the subject matter of claim 1, which also requires that “the BSS color is an identifier of a BSS.” Petitioner acknowledges that a reserved value of 0000 in the color field does not identify a BSS. See Pet. 54–55 (asserting that a that a COLOR field value of ‘0000’ does not represent a valid BSS identifier”). We also recognize, however, that claim 7, depending from claim 1, recites “the BSS color indicated by the signaling field of the PPDU is a predetermined value” and that claim 8, depending from claim 7, recites that the predetermined value is 0. Thus, Choudhury’s reserved value disclosures appear to teach this subject matter of claims 7 and 8, even if claims 7 and 8 are inconsistent with claim 1’s requirement that “the BSS color is an identifier of a BSS.” See Ex. 1001, 21:23–30 (disclosing that the BSS color value may be set to a predetermined value such as zero).” slip op. at 12
