“III. CONCLUSION Because we determine that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing at least one of the challenged claims is unpatentable, we institute inter partes review as to all challenged claims and grounds presented in the Petition. At this stage of the proceeding, we have not made a final determination as to the patentability of any of these challenged claims. ORDER For the reasons given, it is ORDERED that pursuant to 35 U.S.C. § 314, an inter partes review is instituted as to claims 1, 2, 5–8, 11, and 12 of the ’803 patent to determine whether: 1) claims 1, 5–7, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over TS 36.300, TS 36.321, and TS 36.331; 2) claims 1, 2, 5–8, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson and TS 25.331; and 3) claims 5, 6, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson, TS 25.331, and Sebire; and” slip op. at 27
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

“f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34. On this preliminary record, we are persuaded that Petitioner has made a sufficient showing that a POSITA would have had a reason to combine the teachings of Ericsson and TS 25.331.” slip op. at 20

“Court provided a construction for “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service,” as recited in claim 1, and “enablement signal enabling one or more of an application, a function and a service.” Prelim. Resp. 1–6. Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. (citing Ex. 2001, 25–26)) to support its contention that the District Court construed the term “enabled,” as we determined in the prior proceedings, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Ex. 2001, 26; see also IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11. That is, a determination of whether a term is indefinite is not the same thing as construing a claim term. Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabled.” Ex. 2001, 26. Accordingly, although the referenced portion of the District Court’s Memorandum indicates that a POSITA could reasonably ascertain the scope of the claim (id.), nothing in the Memorandum provides a construction of “enabled” as Patent Owner contends. Prelim. Resp. 5. That is, we are unpersuaded that the District Court construed that “‘[a]n application, function, or service is ‘enabled’ by a PDK when it receives information from a PDK in exchange for an access key” or that “hybrid device” includes “an RDC that ‘enable[es] one or more of an application, a function, and a service’ when it forwards such a message to the application, function, or service.” Id. (emphasis omitted, alteration in original). Thus, as in the prior proceedings, we determine that “enabl[ing] one or more of an application a function, and a service” does not require receiving information from a PDK in exchange for an access key or forwarding a message to the application, function, or service.” Id.; see also IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11.” slip op. at 10

“Only those terms in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Petitioner proposes claim construction for “Personal Digital Key (PDK).” Pet. 8–9. Patent Owner does not take issue with Petitioner’s proposed construction for “PDK” but instead requests that we “follow the District Court’s construction” for “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service,” as recited in claim 1, and “enablement signal enabling one or more of an application, a function and a service,” with respect to claim 10. Prelim. Resp. 1–2. Because the parties do not take issue with each other’s proposed claim constructions, there is no term of the challenged claims that is in controversy, and thus, we determine that no term requires explicit construction. See Realtime, 912 F.3d at 1375. However, although it is not necessary to construe the term to resolve the disputed issues before us, we note that Patent Owner provides arguments with respect to “enabling one or more of an application, a function, and a service” recited in claims 1 and 10. Prelim. Resp. 1–2. We addressed similar arguments with respect to these terms in previous proceedings with related patents (see IPR2024-00405, Paper 8 at 11–12; IPR2024-00407, Paper 8 at 12–13; IPR2024-00784, Paper 12 at 10–11), and we similarly address Patent Owner’s contention in this proceeding.” slip op. at 7

Further, according to Petitioner, “Giobbi ’157 teaches that it is advantageous to incorporate PDKs into ‘commonly carried items,’ like phone, since it would eliminate the need for a user to carry a separate PDK device and would reduce the risk of loss.” Id. at 30 (citing Ex. 1005 ¶ 35; Ex. 1003 ¶ 48).

“Owner’s challenge to Petitioner’s Fukui-based grounds is whether, in Fukui, 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.11 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 and10B 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) 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– 11 There is no dispute on this record that the term “module” as used in Fukui is analogous to the term “cassette” as used in the ’423 patent. 8:6.

“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

“Petitioner contends that one of ordinary skill in the art “would have [had] a B.S. degree or equivalent in mechanical or electrical engineering or similar fields, in addition to a minimum of two years of professional experience with or graduate studies involving design, development, and/or utilization of optical communication systems.” Pet. 26. On the present record, Patent Owner does not dispute this proposed level of skill. Prelim. Resp. 1–31. Neither party explains why the outcome of this case would be affected by the adoption of any of the proffered definitions of a person of ordinary skill in the art. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as it appears consistent with the ’542 patent and the asserted prior art. See Okajima v.

“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.

- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“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

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.
