    “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. Considering the substantial investment in the District Court litigation and the rapidly advancing District Court litigation trial date balanced against the timing of the Petition, we determine this factor weighs in favor of discretionary denial.” slip op. at 11

    “According to PTAB guidance, “[b]ased on the Board’s experience, one petition should be sufficient to challenge the claims of a patent in most situations.” Consolidated Trial Practice Guide (“TPG”) 59 (Nov. 2019), available at https://go.usa.gov/xpvPF. “Two or more petitions filed against the same patent at or about the same time (e.g., before the first preliminary response by the patent owner),” the situation we have here, “may place a substantial and unnecessary burden on the Board and the patent owner and could raise fairness, timing, and efficiency concerns.” Id.

Nowhere does the ’835 patent specification indicate a valid region of the integrated circuit device as a whole can be represented by values for less than three parameters x, y, and z, all together, e.g., the command signals, the data signals, and the sampling signals. Also, the ’835 patent describes that the purpose of determining the boundaries of a valid region is to configure an optimal operating point for the integrated circuit device. Ex. 1001, 5:48–51. We have also considered other language in the claims. Each of independent claims 1 and 7 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operation range.” Ex. 1001, 6:56–7:4, 7:18–34. Each of independent claims 12, 20, and 23 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operating range.” Ex. 1001, 7:46–60, 8:28–44, 8:62–10:4. Based on the foregoing, the specification informs us that “valid operation range” is a three-dimensional range. We recognize that the specification does not expressly exclude a two-dimensional range or multiple two-dimensional ranges from being a “valid operation range” of the integrated circuit device.

Nor has Petitioner articulated a reason to do the adjustment in both directions, i.e., adjusting the data signals relative to the sampling signals and adjusting the sampling signals relative to the data signals. We have also determined above, in discussing limitation [1.3], that Petitioner has not sufficiently shown that Johnson’s CCLK signal is a sampling signal. Further, we agree with Patent Owner (Prelim. Resp. 24) that neither delay 55 nor delay lock loop 41 in Johnson’s Figure 4 is used for systematic calibration of any signal or in a signal calibration process. We find that the mere presence of a delay element in a signal path does not reasonably suggest systematic calibration. For the foregoing reasons, Petitioner has not sufficiently shown that” slip op. at 31

    “1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits. See Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 11 at 6 (PTAB Mar. 20, 2020) (precedential) (“Fintiv factors”). “These factors relate to whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Id. In evaluating the Fintiv factors, we take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review,” recognizing that “there is some overlap among these factors” and that “[s]ome facts may be relevant to more than one factor.” Id.” slip op. at 9

    “whether to institute an inter partes review. Applying the standard set forth in 35 U.S.C. § 314(a), we may not institute an inter partes review (also “IPR”) unless the information presented in the petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” However, institution of inter partes review is discretionary. See Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”). For the reasons stated below, we exercise our discretion not to institute an inter partes review.” slip op. at 2

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “Thus, although Petitioner contends that Njølstad implements a dynamically changeable frequency for each domain wherein a local “rate requirement can dynamically be configured” such that “the locally generated clock rate is just high enough to perform the actual processing task” at that rate (Pet. 31 (citing Ex. 1009 § IV.D)), such teaching merely supports Petitioner’s contention that the frequency is dynamically changeable at the local level (id.). However, as Patent Owner points out, such showing is not a compelling disclosure of the frequency generation being independent of the frequencies of the other domains, as required by the challenged claims. Prelim. Resp. 28–34. For the foregoing reasons, we conclude that Petitioner has not presented compelling merits that Njølstad teaches “the frequency being dynamically changeable independently of the frequencies of the clock signals generated for others of the plurality of domains” as recited in claim 1 and similarly recited in claim 8.” slip op. at 25

    “However, Patent Owner argues that Iyer published after the invention to the ’443 patent was actually reduced to practice. Prelim. Resp. 27–28. In particular, Patent Owner provides evidentiary testimonies of Dr. Kaeli (Ex. 2001) and Mr. Albonesi (Ex. 2003) to support its contends the ’443 patent incorporates by reference a paper authored by the inventors and published in February 2002 (Ex. 2005), which demonstrates conception by providing a full written description of the claimed invention. Prelim. Resp. 6–16. According to Patent Owner, a simulation described in the paper embodied the invention in a tangible form, wherein the simulation described in the paper showed that the invention worked for its intended purpose. Id. at 16–19 (citing Exs. 2001, 2003, 2005). Similarly, Patent Owner contends that the application from which Soerensen issued was filed on August 29, 2002, which is after the invention date of the ’443 patent. Prelim. Resp. 35. According to Patent Owner, while Soerensen claims priority to the Soerensen Provisional Application (Ex. 1022), the passages from Soerensen relied on in the Petition are not entitled to the benefit of the filing date of the Soerensen Provisional Application because the subject matter was not disclosed in the manner provided by 35 U.S.C. § 112. Id. We recognize potential merits to Patent Owner’s position. That is, we do not find compelling Petitioner’s contention that the challenged claims would have been obvious Iyer or Soerensen.” slip op. at 31
