      “Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006. 2. Conclusion: PGR Eligibility For the foregoing reasons, and based on the record before us, we determine that Petitioner has not demonstrated that it is more likely than not that the ’202 patent has, or had, at least one claim having an effective filing date on or after March 16, 2013. Accordingly, we determine that the ’202 patent is entitled to the filing date of the ’634 application (October 18, 2006), and, thus, the ’202 patent is not eligible for post-grant review.” slip op. at 18

      “Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals. These two facts provide together a proper reason to limit the claims in this way.”); Phillips v. AWH Corp., 415 F.3d 1303, 1312–1317 (Fed. Cir. 2005) (en banc) (“[T]he specification may reveal an intentional disclaimer, or disavowal, of claim scope by the inventor. In that instance as well, the inventor has dictated the correct claim scope, and the inventor’s intention, as expressed in the specification, is regarded as dispositive.”).” slip op. at 13

      “Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim. Resp. 13 (noting that Petitioner does not identify other limitations in the challenged claims “allegedly lacking support in the ’202 patent family’s applications dating back to U.S. App. No. 11/550,634, filed on October 18, 2006”). Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

      “Patent Owner contends that we should deny institution under 35 U.S.C. § 325(d) “because the Petition presents ‘the same or substantially the same prior art or arguments previously . . . presented to the Office.’” Prelim. Resp. 25–31 (alteration in original). Specifically, Patent Owner explains, the Office previously considered Sedor during the ’542 patent’s prosecution, and Sauter was made of record but not considered during prosecution. Id. Patent Owner, however, states that it “recognizes that this argument only reaches Sauter-based grounds, not Fukui-based grounds. This argument thus only needs to be addressed after the Board confirms the fundamental deficiencies in Petitioner’s Fukui-based grounds.” Id. at 25 n.3. Because, as set forth below, we do not, on the present record, find any “fundamental deficiencies in Petitioner’s Fukui-based grounds” that inhibit institution of trial, we regard Patent Owner’s § 325 request as moot, and we need not consider it further.” slip op. at 10

      “enough to resolve . . . the lead Fukui ground” but that “[t]here are two disputes relevant to the alternative Sauter ground.” Pet. 22. With respect to the first of these “disputes,” Petitioner presents two claim constructions for the claim term or phrase “cassette width as measured between outer side edges thereof of one of one, two, three, four and six standard width units.” Id. at 23. The constructions are said to be from “the co-pending litigation,” with one characterized as “Patent Owner’s proposed construction”6 and the other as “CommScope’s proposed construction.”7 Of note is Petitioner’s 6 The claim construction attributed to Patent Owner is: “cassette width as measured between the outer side edges thereof that accommodates one of one, two, three, four, or six receptable modules.” Pet. 23. 7 Petitioner’s construction is: “The cassette width as measured between the outer side edges thereof equals one, two, three, four, or six times the contention that “[Patent Owner]’s construction cannot be correct,” and accompanying explanation in that respect. Id. at 22–23, 24. Patent Owner acknowledges that there is a dispute between the parties as to the noted claim construction but urges that “[t]he Board, however, need not fully resolve this claim construction dispute,” as, in Patent Owner’s view, the grounds based on Sauter are deficient based on either construction. Prelim. Resp. 21–22. We are mindful of Petitioner’s view that Patent Owner’s litigation construction is not correct. We also question whether that construction adds clarity in substituting “width that accommodates” for “width of,” and replacing “standard width units” with “receptable modules,” without, on this record, support for such word variations. Nevertheless, our determination whether to institute trial does not require resolution of any claim construction dispute, nor does it necessitate that we adopt any particular construction for the pertinent claim term. 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.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet.

Fred Schubert, testifies that “two separate lines straddling circuitry are [not] one line.” Ex. 2001 ¶ 64. The dispute between the parties on this issue is largely one of claim construction: should the term “wiring line” in claim 7 be construed broadly enough to encompass a collection of lines separated by a sample hold circuit? In order to determine that Fujikawa discloses or teaches the recited wiring lines, we would need to answer this question in the affirmative. Yet, as discussed above, neither party proposes construing “wiring line,” or any other term used in the claims of the ’606 patent. Pet. 18; Prelim. Resp. 7. The failure to argue for and sufficiently support a broad construction of the term “wiring line” means that Petitioner does not show sufficiently, for purposes of supporting institution of review, that Fujikawa discloses or teaches the “wiring line” limitation of claim 7. b) Conclusion Regarding Claim 7 Based on the record presented, we determine that Petitioner has not shown that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 7 is unpatentable as anticipated by or obvious in view of Fujikawa.” slip op. at 11

Prior to institution, Patent Owner’s declarant asserted that a POSITA would have had at least a bachelor’s degree in electrical engineering and a minimum of 3-4 years of industry experience in the telecommunications industry and disagreed that industry experience specifically with respect to twisted-pair data cables was necessary to qualify as having ordinary skill in the art. Ex. 2001 ¶ 26 (cited at Prelim. Resp. 22 n.6). Patent Owner stated, however, that any differences between the parties’ proposed definitions “are insubstantial and do not impact the analysis of the issues presented.” Prelim. Resp. 22 n.6. In our Decision on Institution, we adopted Petitioner’s proposal of a person of ordinary skill in the art (POSITA) as someone that “would have had a bachelor’s degree in electrical engineering and a minimum of 3-4 years of industry experience in connection with designing, manufacturing, and testing of twisted-pair data cables,” and an “individual with a master’s degree in electrical engineering would require less industry experience (e.g., 1-2 years).” Inst.

      “Petitioner’s arguments are not persuasive. Mr. Cornelison’s testimony that a POSITA would understand that the tape shown in Figure 13C “has three layers aligned along the side edges” is not credible. See, e.g., Ex. 1006 ¶ 138. Mr. Cornelison’s testimony that Figure 13C is only “intended to identify and illustrate the three different layers of the multi-layer tape,” not to show the relative positions of the layers relative to each other (id. ¶ 137), is belied by his own testimony, in which he states that Figure 13C shows “metallic layer 133 extends to the front edges of dielectric layers 135 and 137 (id. ¶ 136). Additionally, neither Petitioner nor Mr. Cornelison provide persuasive evidence to support the contention that it would take “much more time and be more complex to make all three layers” in Figure 13C offset from each other or that it would be more costly to make than using the customary slitting processes. See Ex. 1006 ¶ 138. Although Mr. Cornelison provides evidence as to how the slitting process can be used to manufacture barrier tape, he does not provide any evidence to support his contention that the proposed slitting processes is in fact less expensive or complex than other methods. See Ex. 1006 ¶ 138. Indeed, Mr. Cornelison does not address the particular methods disclosed in Glew to manufacture the disclosed multi-layer tapes nor persuasively explain why these disclosed methods would be more costly or complex as compared to the “slitting” process. Ex. 1008 ¶¶ 199–201 (stating the multi-layer tapes can be manufactured in a “variety of ways” including bonding the various layers using adhesive or other bonding agents,” mechanically affixing or bonding the layers, needlepunching, thermal bonding, ultrasonic welding, or calendar bonding). We determine that this portion of Mr. Cornelison’s testimony is conclusory and unsupported and is entitled to little weight. Accordingly, Petitioner has not sufficiently shown that Glew discloses conductive material that extends to the lateral edges of the dielectric material as required by claims 1 and 18. As such, Petitioner has not shown a by a preponderance of the evidence that Glew anticipates independent claims 1 or 18 or the challenged claims that depend therefrom.” slip op. at 42

      “Thus, although the Specification does not use the term “lateral edge,” the Specification and figures of the ’030 patent make clear, that in the embodiments having a conductive layer that extends to the edges of the dielectric layers of the tape, the referred to “edge” is the edge of the “long side” of the tape that extends in the longitudinal direction. See, e.g., Ex. 1001, 7:49–51 (stating in some embodiments conductive layer 302 may not extend to the edge of tape 110), 8:1–25 (stating, inter alia, pairs 102 could electrically couple to the corresponding edge 306 resulting in increased ANEXT), 8:41–46, 10:30–36 (stating that the tape edge lies over a pair of conducts and the pair generates more ANEXT). Our construction of term “lateral edge” is supported by Roberts, which also refers to the edges of the long side of the tape extending in the longitudinal direction as the “lateral edges.” See, e.g., Ex. 1009, 2:20–24 (“a shield made from a plurality of tapes helically disposed, the lateral edges of which overlap adjacently lying tapes”), 2:42–46 (“a shield composed of a plurality of …, the lateral edges of which overlap adjacently disposed tapes”), 4:27–33 (“the plastic-coated metal foil shield (15) [FIG. 2] has lateral edges that overlap,” “the lateral edges of the shield overlapping one another”), 4:34–40 (“The lateral edges of the helically disposed tapes [of FIG. 3] overlap adjacently lying tapes.”), 5:65-75 (“the shield (15) [of FIG. 10] is made up of a plurality of tapes, the lateral edges of which overlap adjacently disposed like tapes”), Figs. 2, 3, 10. We credit Dr. Eldering’s testimony that these disclosures of Roberts shows that a POSITA would understand that a tape’s “lateral edges” are the edges running along the sides of the tape parallel to the longitudinal direction. See Ex. 2001 ¶¶ 64–65; see also Thales Visionix, Inc. v. United States, 415 F.3d 1335, 1348 (Fed.

      “contentions set forth in its Petition are insufficient to show that Cook discloses a barrier tape having a conductive material contained between two layers of dielectric material where the conductive material extends to each lateral edge of the two layers of the dielectric material, as required by claims 1 and 18, and further that the conductive material be continuous as required by claim 1. We agree with Patent Owner that Petitioner relies on multiple disparate embodiments of Cook for each of these limitations without sufficiently articulating how a single embodiment satisfies the requirements of claim 1 or 18 or articulating how the disparate embodiments may be combined to arrive at claim 1 or 18.

Id. We do not think the information of record is sufficient to antedate Krantz and Herrmann such that we should deny institution of inter partes review on that basis. First, Patent Owner’s arguments rely on the testimony of inventor Stacey C. Lum, who has not yet been subject to cross-examination. See Prelim. Resp. 35–45 (citing Ex. 2003). Second, Petitioner identifies several issues where further development of the record may be helpful. For example, Patent Owner’s asserted date of conception is associated with the date of an engineering specification included in the record as Exhibit 2011. See Prelim. Resp. 35–36 (citing Ex. 2003 ¶ 12; Ex. 2011; Ex. 2012). We agree with Petitioner (see Prelim. Reply 4–5) that it is unclear, based on the present record, whether Exhibit 2011 corroborates the testimony supporting Patent Owner’s conception date given that the present record does not establish the author of Exhibit 2011. See Ex. 2003 ¶ 22 (inventor Stacey C. Lum testifying only that “InfoExpress personnel drafted EX2011”).
