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.

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.

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.

“Stated somewhat generally, the core question underlying Patent Owner’s challenge to Petitioner’s Fukui-based grounds is whether a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette. We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and 10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) and forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 8:6. Thus, conversion module 20 is recognizable has having a singular system of fiber optic components within its body. At this time, we regard such characterization of the coupled unit modules 10A and 10B as reasonably giving rise to an understanding that the resulting conversion module 20 constitutes a unitary module or cassette component.” slip op. at 20

“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.

Finally, as to motivation for combining Kuwata and Fisher to practice the invention of claim 1, Petitioner’s contentions and Dr. Stevenson’s testimony justify institution of review. In particular, Dr. Stevenson testifies that a person of ordinary skill in the art would have been motivated, in light of Fisher’s disclosures regarding updating of data files on a camera, to configure Kuwata’s camera to download updated image processing control data from a server via the Internet, in order to pair the camera with various printers including printers that were not yet on the market when the camera was manufactured. See Pet. 15–18, 22–26; Ex. 1003 ¶¶ 86–89, 102–108. Based on the present record, we conclude Kuwata does not teach away from this combination, as Patent Owner would have it. Kuwata merely discloses that the camera manufacturer (as opposed to individual users of the camera) is in the best position to optimize the output control information CI utilized by the camera to reduce differences between images displayed to the user by the camera and images that are outputted by particular printers. See Ex. 1005 ¶¶ 75, 77. This does not detract from the benefits of updating the output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Indeed, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶ 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers. For the foregoing reasons, we conclude the preliminary record supports, sufficiently to justify institution, Petitioner’s contention that a person of ordinary skill in the art would have been motivated to combine Kuwata and Fisher to practice the invention of claim 1.” slip op. at 24

Applying that standard on behalf of the Director (37 C.F.R. § 42.4(a)), we institute an inter partes review to determine whether Petitioner demonstrates by a preponderance of the evidence that claims 1–8, 10–16, and 18 are unpatentable, considering all grounds in the Petition directed to those claims.

In considering Federal Circuit precedent and our rules, we conclude we cannot institute a trial on claims that have been disclaimed, and, thus, no longer exist. Our conclusion is consistent with the statutory scope of inter partes review as laid out in 35 U.S.C. §§ 311(b) and 318(a) and is not at odds with SAS, supra. See, e.g., SAS, 584 U.S. at 367 (recognizing that “the claims challenged ‘in the petition’ will not always survive to the end of the case; some may drop out thanks to the patent owner’s actions”). Accordingly, we treat claims 9 and 17 as having never been part of the ’056 patent, such that Petitioner cannot seek inter partes review of those claims.

“c) Motivation to Combine Based upon review of the full record, we determine Petitioner has articulated a sufficient reason a POSITA would have added the foamed polymer tape of Jachimowicz to Yanagita’s cable between core material 2 (separator) and at least one set of twisted pairs. See Pet. 40–42. In particular, Petitioner states that additing a foamed polymer tape to Yanagita’s separtor core material 2 would have been expected to improve the electrical perforamce of the cable by reducing the capitance between twisted pairs on one side of Yanagita’s separator and twisted pairs on the other side, thus reducing current leakage between them and reducing the transmission loss due to such leakage. Pet. 42 (citing Ex. 1007 ¶¶ 45, 139). Petitioner asserts that a POSITA would have been motivated to add a foamed polymer tape, such as Jachimowicz’s foamed polyethlyene tape to Yangida’s core, because it would have been expected to beneficially lower the dielectic contsant of the material between twisted pairs on either side of the separator due to the addition of low-dielectric constant foamed material.

“To the extent Petitioner argues that Dr. Eldering does not meet the minimum qualifications of a POSITA, we disagree.

Inst. Dec. 8–9. Dr. Eldering holds a Ph.D. in electrical industry and, thus, less than 3–4 years of industry experience is required. Moreover, Dr. Eldering’s declaration, testimony, and CV demonstrate that Dr. Eldering has many years of industry experience with twisted pair data cables.
