“For purposes of this Decision, we adopt the definition of the level of ordinary skill in the art proposed by Petitioner. As to the inclusion of physics in Petitioner’s definition, Dr. Singhose (a professor of mechanical engineering) testifies as to why undergraduate mechanical engineering degree holders would have the requisite knowledge here, but does not testify that undergraduate physics degree holders would not. See Singhose Decl. ¶¶ 2, 27, 28. In addition, Patent Owner and Dr. Singhose require “a four-year degree in mechanical engineering or a closely related field,” but fail to identify what fields are “closely related.” See Prelim. Resp. 11; Singhose Decl. ¶ 27. Based on the Morse Declaration, we are persuaded at this stage that a hypothetical undergraduate physics degree holder would have adequate knowledge for one of ordinary skill in the art of the invention here. See Morse Decl. ¶ 31. As to the requisite years of experience proposed in the definitions— three for Petitioner versus “at least one” for Patent Owner—we note that Patent Owner’s definition is broader than, but includes, Petitioner’s definition. Moreover, for both the inclusion of physics and the years of experience issues, Patent Owner acknowledges that the arguments in the Preliminary Response “are not impacted based on which definition is applied.” Prelim. Resp. 12 (citing Singhose Decl. ¶¶ 30–34). Further, Patent Owner does not argue at this stage that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would understand either the challenged patent or the prior art.” slip op. at 11

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Petitioner does not propose express constructions for any claim terms. Pet. 12. Patent Owner also does not propose any express constructions. See Prelim. Resp. 12. On the current record, we need not construe explicitly any claim terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).

Patent Owner argues, however, that Petitioner has “fail[ed] to identify any structure in the ’007 Patent to perform the claimed function.” Prelim. Resp. 10. We disagree. Petitioner identifies the structures in the Specification corresponding to the “lifter” as follows: The “lifter” (“lifter member”) of the ’007 patent includes a rotatable cam lifter 100 (yellow below left), with pin 104, 106, and 108 (green) on its face surface that engage protrusions 92 (blue) on the driver member 90 (orange). ’007 patent, 9:36–52, 16:39–53, Fig. 12.

This identification of corresponding structure is sufficient to satisfy 37 C.F.R. § 42.104(b)(3).

“gas pressure system” recited in the preamble of independent claims 1 and 17. Prelim. Resp. 21–22. Patent Owner further argues that Petitioner, through its comparison of claims 1 and 17 to Haley, improperly implies that the “gas pressure system” can be “limited to a distinct portion of a power tool.” Id. at 23. Patent Owner contends that such an interpretation is improper because the “gas pressure system” must refer to “the entire system,” because the “structure of the claims themselves . . . include[s] . . . every component of the tool.” Id. We disagree. The “gas pressure system” recited in the preambles of claims 1 and 17 expressly refers to a system that is “for a power tool” and thus does not necessarily refer to “the entire” tool or “every component of the tool.” Ex. 1001, 39:6 (claim 1), 40:51 (claim 17). Neither claim 1 nor claim 17 recites, for example, the lifter or driver, which are required elements of an “entire” tool. Id. at 39:6–22 (claim 1), 40:51–67 (claim 17). The lifter and driver are introduced in dependent claims 2 and 18. Id. at 39:23–30 (claim 2), 41:1–9 (claim 18). Still other necessary components of a tool, e.g., a motor and power source, are introduced in dependent claims 5 and 19. Id. at 39:40–42 (claim 5), 41:10–13 (claim 19). By contrast to claims 1 and 17, independent claims 9 and 14 recite a “portable fastener driving tool” and expressly recite many necessary components of such a tool including the driver, lifter, prime mover, and power source. Id. at 39:54 (claim 9), 40:20 (claim 14). Accordingly, we find that the “gas pressure system” of claims 1 and 17 broadly refers to a portion of a power tool rather than the “entire system” or “every component of the tool.” slip op. at 8

“The two proposals are materially similar in the education requirement, but differ marginally in professional experience required (three versus five years). See supra. While we were persuaded, on the preliminary record, that both Petitioner’s and Patent Owner’s proposals were consistent with the problems and solutions in the ’202 patent and the prior art of record, on balance, we determined that Petitioner’s proposal was a better reflection of the level of skill in the prior art, and we therefore adopted it for our Institution Decision. See Institution Dec. 12–13. For this Decision, we adopt the description of the person of ordinary skill articulated by Petitioner and used previously in our Institution Decision. In light of our review of the complete record, we find that this formulation is consistent with the ’202 patent, the prior art of record, and is supported by the testimony of Dr. Baker.

“requirement.” Pet. Reply 5. We do not agree with Petitioner. We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

“When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party.

To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet.

“On the present record and for the purpose of this Decision, we agree with Petitioner that the proper construction of “communications unit” encompasses multiple DRUs or antenna units. Although Patent Owner is correct that not every embodiment needs to be reflected in every claim, and indeed, some embodiments may not appear in any claim, we do not agree that there is evidence supporting Patent Owner’s argument that the construction of “communications unit” should be narrowed to the embodiment requiring only one DRU/antenna. The cited claims do not indicate that multiple units may not transmit at the sets of frequencies recited. Additionally, although Patent Owner cites claim 16 as requiring that each communications unit is a single DRU, if that were a correct reading of claim 16, it is not clear what the claim recitation would add, as it would not narrow the prior recitation of a “communications unit” from claim 15.

Because our analysis is fact driven, no single factor is determinative of our conclusion. Considering these five Fintiv factors, we determine that they favor a discretionary denial. 2. Assessment of the Compelling Merits As we have found that the first five Fintiv factors favor discretionary denial, we proceed to assess whether the record shows that Petitioner has presented a compelling unpatentability challenge.” slip op. at 16

“While we generally agree with Patent Owner that a person of ordinary skill in the art would understand that a truss and beam, as used in the ’690 patent, are two different structures, serve different purposes, and provide different benefits to the overall design of a chassis, Patent Owner identifies the function, but not the structure, of a truss and beam. After considering the extrinsic and intrinsic evidence, we construe: (1) a beam to be a “body, with one dimension large compared with the other dimensions, configured to carry lateral loads (perpendicular to the large and bending dimension) and bending movements;” and (2) a truss to be a “frame built from members in tension and compression.” These definitions are consistent with the support structures shown in Figures 7 and 9 and discussed in column 3, lines 21–48 of the Specification. Referring to Figures 7 and 9, for example, truss 93C is a frame built from members in tension and compression and beam 93D has one large dimension and supports loads applied to its perpendicular axis. In addition, third section 93 of chassis 90 has beams, not trusses. Ex. 1001, 3:26–28.” slip op. at 18

Petitioner relies on Bezama to supply both of these claim elements, and sets forth rationales for why one of ordinary skill in the art would have had reason to combine these teachings of Bezama with Lyon so as to arrive at the claimed invention. See Pet. 67–68 (citing Ex. 1003 ¶¶ 121–124) (contending that Bezama discloses a recessed transverse groove, and that a POSITA would have known that incorporating such a groove into Lyon’s microchannel walls would have improved fluid flow characteristics); 71–73 (citing Ex. 1003 ¶¶ 128–132) (contending that Bezama discloses that the separator sheet overlying the fins can be made of a compliant material, and that a POSITA would have known that incorporating such a material into Lyon’s Plate 240 would have minimized coolant bypass between the fins and the plate). Patent Owner makes a single patentability argument for claim 1—it contends that neither Lyon nor Bezama discloses a compliant member that is “matingly engaged” with the second side of the housing member.
