“2. Conclusion Regarding the Merits The discussion above identifies weaknesses in the Petition that we have considered in our evaluation of Fintiv factors. While we do not make a determination regarding whether the Petition shows that there is a reasonable likelihood of prevailing were we to institute, for the reasons given, we determine that this Petition does not present particularly strong merits.

We take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. Because of the Sotera stipulation, factor 4 weighs strongly in favor of not exercising discretion. However, two other factors weigh in favor of exercising discretion, especially the trial date factor. The merits of Petitioner’s challenge are not particularly strong. A balanced assessment of the factors leads us to exercise discretion to deny the Petition. Therefore, we conclude that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review.” slip op. at 22

“partes review “allays concerns about inefficiency and duplication of efforts,” and strongly weighs against exercising our authority to deny institution. Fintiv, Paper 11 at 6. Of the three district court proceedings, the Lenovo Group case, pending in the Eastern District of Texas, is the most significant to our analysis here. In the Lenovo Group case, Lenovo Group has not requested a stay. Prelim. Resp. 16. Patent Owner argues that the Lenovo Group case is not likely to be stayed based on that court’s low grant rate in other cases and the progress of that case in particular. Id. at 17. The district court in the HP case denied a stay without prejudice and stated that a stay could be reconsidered in the future depending on the outcome at the PTAB. Prelim. Reply 3. The Dell case has been stayed. Id. On this record, we decline to speculate as to how any of the involved district courts where no stay is pending might rule on any future motion to stay. Thus, we determine that, while one stay has been granted, the lack of a stay in the other underlying district court cases, especially the Lenovo Group case, is not sufficiently persuasive to weigh this factor against exercising discretion. Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 15 at 12 (PTAB May 13, 2020) (informative), cautions against speculating whether the district court would grant a stay if one were requested. Therefore, this factor has a neutral effect on the overall balancing of the Fintiv factors. B. Proximity of Trial Date to Projected Statutory Deadline (Factor 2) The scheduled trial date for the Lenovo Group case is November 3, 2025, which is about six months prior to the expected date for the final written decision here (i.e., late April 2026). See Prelim. Resp. 20; IPR2024- 01429, Ex. 2002 (Lenovo Group case Docket Control Order), 1. Petitioner argues this trial date is uncertain. Prelim. Reply 3. Further, Petitioner focuses its argument on what it terms a “growing backlog” in the Eastern District of Texas and “associated scheduling uncertainty.” Id. at 4. Petitioner refers to the status of the HP case, which is currently set for trial on September 21, 2026, and the stay in the Dell case. Id. Patent Owner responds that “[b]oth the scheduled trial date and the date of trial [in the Lenovo Group case] based on median time-to-trial statistics occur months before a final written decision would be expected here.” Prelim. Sur-reply 4. Patent Owner asserts that the time-to-trial statistics for the Eastern District of Texas project a median time-to-trial of 21.9 months. Prelim. Resp. 20–21 (citing Ex. 2007, U.S. District Courts Federal Court Management Statistics–Profiles—September 30, 2024). This projection yields a trial date that is prior to the expected final written decision date of April 2026. Prelim. Sur-reply 4. As with the previous factor, the status of the Lenovo Group case is our focus here. As stated, that trial is set to occur about six months before a final written decision would issue in this proceeding. The district court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 20. We are not persuaded by Petitioner’s unsupported argument that the trial date is uncertain. We also consider the fact that the median time-to-trial statistic discussed by both parties projects a trial date earlier than the actual date set by the district court. Ex. 2007; Prelim. Sur-reply 1.

“E. Conclusion Regarding the Merits Petitioner does not present particularly strong merits. Petitioner’s arguments on the “bus limitation,” to succeed at trial, would require addressing a claim construction issue that was never addressed in the Petition and is arguably contradicted by the ’520 patent, which discloses transmitting packets representing a plurality of different control signals on a single bus. See Prelim. Sur-reply 2 (citing Ex. 1001, 7:34–38, 9:23–25, 9:50–54). Similarly, prevailing on the “modified protocol” issue would require proving that the HDMI–C protocol, which uses the same separate channel arrangement for CEC and DDC as standard HDMI, is sufficiently “modified” to meet the claim.

“Petitioner contends that a person of ordinary skill in the art “at the time of the ’505 patent had at least a bachelor’s in EE/CE/CS, physics, or equivalent, and two years of experience with cellular telecommunications, radio-access network architectures, protocols and signal propagation,” where “[m]ore education can supplement practical experience and vice versa.” Pet. 6 (citing Ex. 1003 ¶¶ 51–55). Patent Owner does not comment on Petitioner’s formulation or offer any competing formulation in its Preliminary Response. See generally Prelim. Resp.

“for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:42–45. The preamble of independent claim 9 similarly recites “a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions.” Id. at 14:4–7. Petitioner, however, contends that “this claim term is not part of the preamble” and that “the preamble is [only] ‘In a multi-user detection system in which interfering signals are purposely allowed to exist.’” Pet. 14. Regardless, Petitioner further contends, to the extent there is any argument that that recitation is part of the preamble, “it is limiting at least because it provides antecedent basis to the ‘parameter estimation unit’ and ‘associated channel transfer functions’ terms that are used in the remainder of the body of the claims and is ‘essential to understanding the structural limitations’ of the parameter estimation unit.” Id. Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45. The preamble of claim 9 is similar. Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are 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. Cir. 2019). Because Patent Owner does not dispute Petitioner’s contentions with respect to the preamble recitations, and our decision herein need not reach a determination with regard to that question.” slip op. at 17

“A claim limitation using the phrase “means for” creates a rebuttable presumption that the drafter intended to invoke 35 U.S.C. § 112 ¶ 6.6 See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015). Section 112 ¶ 6 provides that: An element in a claim for a combination may be expressed as a means . . . for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. When construing a means-plus-function limitation under § 112 ¶ 6, it is necessary first to identify the claimed function, and then to look to the specification to identify the corresponding structure for that function. In re Aoyama, 656 F.3d 1293, 1296–97 (Fed. Cir. 2011); Cardiac Pacemakers, Inc. v. St. Jude Med., Inc., 296 F.3d 1106, 1119 (Fed. Cir. 2002). Under that second step, “structure disclosed in the specification is corresponding 6 Section 4(c) of the Leahy-Smith America Invents Act (AIA) re-designated 35 U.S.C. § 112 ¶ 6, as 35 U.S.C. § 112(f). Because the ’676 patent has a filing date before September 16, 2012 (effective date of the statute), we refer to the pre-AIA version of 35 U.S.C. § 112. associates that structure to the function recited in the claim.” Med. Instrumentation & Diagnostics Corp. v. Elekta AB, 344 F.3d 1205, 1210 (Fed. Cir. 2003). Our Rules specifically require that the petition identify the corresponding structure in proposing a construction for a means-plus-function claim limitation. 37 C.F.R. § 42.104(b)(3). “This inquiry is undertaken from the perspective of a person of ordinary skill in the art.” Cardiac Pacemakers, 296 F.3d at 1113.” slip op. at 19

“In view of the parties’ agreement to adopt Patent Owner’s construction and the District Court’s persuasive analysis, we find that the “multi-user detector decision unit” terms in claims 1 and 10 are properly construed on the record before us to recite the functions “using decision criteria to determine a selected multi-user detector” for claim 1 and “select[ing] a multi-user detector based upon at least one threshold” for claim 10, both of which have the following corresponding structure: a MUD decision unit 220 (or, alternatively, decision logic unit 520) configured to perform one or more of the several decision algorithms (e.g., the BER/User, SINR/Symbol, Filtered SINR/Symbol, Detected Amount/Symbol, Correlation Matrix Ratio/User, Correlation Matrix Eigenvalues, Computational Complexity, Number of Bits, Number of Users, and other algorithms) disclosed at 8:12–18, 13:35–14:40, 15:3–21, 19:43– 48, 19:56–62, and 20:41–49 of the ’492 Patent.” slip op. at 12

Therefore, Petitioner fails to show a reasonable likelihood of success in establishing that claims 1 and 10 would have been obvious over Onggosanusi and Egnor. Claims 2–9 and 11–16 depend from claims 1 and 10 respectively, and thus Petitioner likewise fails to show a reasonable likelihood of success that those dependent claims would have been obvious over Onggosanusi and Egnor.

Infineum USA L.P., IPR2018-00923, Paper 9 at 10 (PTAB Nov. 7, 2018) (informative) (citing SAS Inst. v. Iancu, 138 S. Ct. 1348, 1356 (2018); Harmonic, 815 F.3d at 1367). Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources. See, e.g., Deeper, UAB v. Vexilar, Inc., IPR2018-01310, Paper 7 at 42–43 (PTAB Jan. 24, 2019) (informative) (denying institution where a petitioner demonstrated a reasonable likelihood of success on only two out of twenty- a petitioner demonstrated a reasonable likelihood of success on only two out of twenty claims). Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims. Accordingly, we need not, and do not, take any position as to Petitioner’s showing on Ground 2 but instead exercise our discretion to deny review.” slip op. at 21

“Based on the preliminary record, we can reasonably expect trial in the parallel district court proceedings to begin four to five months prior to the deadline for our final written decision, based on the scheduled trial date and the median time-to-trial statistics. See Fintiv Memo 8–9 & n.12 (approving the use of median time-to-trial statistics). Even if the proceedings are staggered, at least one of the proceedings would likely begin and conclude well before our decision, making it highly likely that there will be duplicate efforts in evaluating the challenged claims based on the prior art. Thus, we agree with Patent Owner that the second factor weighs substantially in favor of discretionary denial.” slip op. at 9
