“Statutory Deadline We weigh this factor as favoring the exercise of discretionary denial. The parties agree that the projected statutory deadline for issuing our Final Written Decision (April 23, 2026) is a little more than six months after trial is currently scheduled in the District Court litigation (October 6, 2025). Supp. Br. 4; Prelim. Resp. 19–20. Because the currently scheduled District Court trial is set to begin six months before our deadline to reach a final decision, this factor favors discretionary denial in this case. See Fintiv, Paper 11 at 9. C. Factor 3 – Investment in the Parallel Proceeding We weigh this factor as favoring the exercise of discretionary denial. Showing substantial investment in the District Court litigation, document production is substantially complete and fact discovery will be completed within two weeks of this Decision on Institution. Ex. 2001, 4–5 (Second Amended Docket Control Order). Further, a hearing on claim construction and associated briefing is complete. Id. And, the deadline to serve Institution. Id. at 4. These actions show that there has been notable investment by the parties in the District Court litigation. Furthermore, we must consider this parallel work in relation to the October 6, 2025 District Court litigation trial date, which is six months before the projected statutory deadline of our Final Written Decision. See Fintiv, Paper 11 at 10. As work in the District Court litigation has moved beyond preliminary stages into more advanced stages, instituting at this time implicates at least some duplicative costs. See id. On the matter of petition timing, it is often reasonable for a petitioner to wait to file its petition until it learns which claims are being asserted against it in the parallel proceeding. Fintiv, Paper 11 at 11. Here, Petitioner filed its petition on September 27, 2024, which is four months after receiving Patent Owner’s May 29, 2024 disclosure of asserted claims and infringement contentions and nine months after it was served Patent Owner’s December 29, 2023 infringement complaint. Ex. 1017; Ex. 1018, 1. Further, Petitioner served its amended invalidity contentions in the District Court litigation on December 17, 2024, i.e., after it filed its Petition.5 We do not find the timing of the Petition in this case to outweigh the significant investment in the District Court litigation.

“Pursuant to 35 U.S.C. § 314(a), an inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons provided below, we determine that Petitioner has demonstrated a reasonable likelihood that at least one claim of the ’968 patent is unpatentable, and we institute an inter partes review. 37 C.F.R. § 42.108(a).” slip op. at 2
- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) does not applyDecided for petitioner
“We agree that the lack of the word “means” recited in claims 1 and 9 creates a rebuttable presumption that § 112(6) does not apply. Williamson, 792 F.3d at 1348. “When a claim term lacks the word ‘means,’ the presumption can be overcome and § 112[(6)] will apply if the challenger demonstrates that the claim term fails to ‘recite[] sufficiently definite structure’ or else recites ‘function without reciting sufficient structure for performing that function.’” Id. at 1349 (citation omitted). “One way to demonstrate that a claim limitation fails to recite sufficiently definite structure is to show that, although not employing the word ‘means,’ the claim limitation uses a similar ‘nonce word that can operate as a substitute for ‘means’ in the context of § 112 [(f)].’” MTD Products, Inc. v. Iancu, 933 F.3d 1336, 1341 (Fed. Cir. 2019) (quoting Williamson, 792 F.3d at 1350). Patent Owner argues that “[a] general-purpose computer, i.e., a ‘controller,’ fails to recite sufficiently definite structure for performing the DSC’s claimed function.” PO Sur-Reply 3–4. Petitioner responds that the term “controller” has previously been found to not invoke § 112(6) because it is understood as having a definite meaning of structure. Pet. Reply 1–2 (citations omitted). Petitioner is correct that the Board and district courts have in some cases found a “controller” to recite sufficient structure. On this preliminary record, we are not persuaded that the evidence is sufficient to establish that the term “designation software controller” fails to recite sufficiently definite structure and overcome the presumption that § 112(6) does not apply. At this juncture, neither party has provided sufficient evidence as to how the claimed “designation software controller” would reasonably be understood by persons of ordinary skill in the art. See Williamson, 792 F.3d at 1349 (“The standard is whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure.”). In addition, regardless of whether “designation software controller” alone connotes structure, the claim language that follows the term “designation software controller” appears to provide structure. Specifically, the claim language appears to include a step-by-step procedure, namely 1) keep the information in memory in response to a termination of viewing; and 2) designate the succeeding part of the digital moving image contents when the viewing starts again. See Ergo Licensing, LLC v. CareFusion 303, Inc., 673 F.3d 1361, 1365 (Fed. Cir. 2012) (“Even described ‘in prose,’ an algorithm is still ‘a step-by-step procedure for accomplishing a given result.’”); Sage Prods., Inc. v. Devon Indus., Inc., 126 F.3d 1420, 1427–28 (Fed. Cir. 1997) (“where a claim recites a function, but then goes on to elaborate sufficient structure, material, or acts within the claim itself to perform entirely the recited function, the claim is not in means-plus-function format”). Accordingly, for purposes of this decision, we do not construe the claimed “designation software controller” as a means-plus-function limitation. No further construction of this term is necessary for purposes of this decision. During trial, the parties may provide further briefing on this issue.” slip op. at 10

“(“POSITA”) would have had “a Bachelors’ degree in electrical or computer engineering or a comparable field of study, plus approximately two to three years of professional experience with television and digital display systems, distributed multimedia communications, and networked computer systems.” Pet. 3–4 (citing Ex. 1002 ¶ 48). Patent Owner does not challenge Petitioner’s proffered definition as to the level of ordinary skill in the art. Prelim. Resp. 5. For purposes of this Decision, we adopt Petitioner’s assessment, which is consistent with the level of skill reflected in the specification and asserted prior art.” slip op. at 14

“viii. Conclusion as to Claim 1 Based on the current record, we are persuaded by Petitioner’s showing for limitations 1[a] through 1[e]. Accordingly, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its assertion that claim 1 would have been obvious over Lee.” slip op. at 22
