“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

“IV. REQUEST FOR DENIAL UNDER 35 U.S.C. § 325 Patent Owner contends that the Board should exercise its discretion to deny under 35 U.S.C. § 325(d) on the theory that the Petitioner relies on substantially the same prior art and arguments that were previously considered by the Office. See Prelim. Resp. 31–37. Patent Owner, however, states the following: “Patent Owner 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 31, n.4. Because, as set forth above, we do not agree at this time as to any “fundamental deficiencies in Petitioner’s Fukui-based grounds” that inhibit institution of trial, we regard Patent Owner’s § 325 request as moot, and need not consider it further.” slip op. at 23

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 or necessitate that we adopt any particular construction for any claim term.

“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.

“Patent Owner’s position in this regard invites us to err “by looking at [Fisher] individually” and separately from Kuwata, because “[t]he question in an obviousness inquiry is whether it would have been obvious to a person of ordinary skill in the art to combine the relevant disclosures of the two references, not whether each individual reference discloses all of the necessary elements.” Palo Alto Networks, Inc. v. Centripetal Networks LLC, 122 F.4th 1378, 1385–86 (Fed. Cir. 2024) (quoting Game & Tech. Co. v. Wargaming Grp. Ltd., 942 F.3d 1343, 1352 (Fed. Cir. 2019)); In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (nonobviousness is not established by attacking references individually when unpatentability is predicated upon a combination of prior art disclosures); see also KSR, 550 U.S. at 420–421 (stating “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” and “in many cases a person of ordinary skill will be able to fit the teachings of multiple patents together like pieces of a puzzle”). 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

“disclaimer,” and “[n]o inter partes review will be instituted based on disclaimed claims.” 37 C.F.R. § 42.107(e). As a result of the statutory disclaimer, claims 9 and 17 are no longer regarded as claims challenged in the Petition. See Vectra, 162 F.3d at 1383 (“This court has interpreted the term ‘considered as part of the original patent’ in section 253 to mean that the patent is treated as though the disclaimed claims never existed.”) (citing Guinn v.

Cir. 2019) (disclaimer of claims during District Court patent infringement litigation “mooted any controversy” over the disclaimed claims, ending the Article III case or controversy requirement for District Court jurisdiction). 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. Thus, we deny institution of review as to whether disclaimed claims 9 and 17 are unpatentable per Petitioner’s Grounds Three and Four.” slip op. at 32

“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. First, our definition of a POSITA requires 3–4 years of industry experience for those holding only a bachelor’s degree and that less years of industry experience is required for those with additional education. 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. See, e.g., Ex. 2001 ¶ 13 (discussing his 1990–1993 industry experience with twisted wire pairs, including research regarding delivery of high-speed digital data services over twisted wire pair cable), ¶ 14 (discussing industry experience at General Instrument, including the development of products using twisted wire pair cable for distribution of voice signals), ¶ 15 (discussing additional industry experience including evaluation of crosstalk in systems using twisted pair wire cabling and optimizing modulation format), App’x A; Ex. 1070, 201:1–202:7.
