      “Relying on the declaration testimony of Dr. Akl, Petitioner contends that an ordinarily skilled artisan for the ’128 patent “would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with two years of experience designing or developing wireless networks, including long-term evolution LTE/4G or 5G new radio (NR) cellular technology.” Pet. 4. Petitioner additionally contends that “[a]dditional years of experience could substitute for an advanced-level degree (and vice versa).” Id. Patent Owner states that “[f]or the purposes of this Preliminary Response only, Patent Owner utilizes Petitioner’s proposed level of skill in the art.” Prelim. Resp. 2. Based on this record, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’128 patent and the asserted prior art, and we apply it in our obviousness evaluations below.

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

      “On the current record, we find that Petitioner has shown sufficiently that Cirik teaches the claimed “first configuration parameters for beam failure recovery, comprising first random access parameters.” See Pet. 13– 17. Patent Owner argues that Petitioner fails to address this limitation, but we disagree. Prelim. Resp. 3. As we have set out above, Petitioner has provided a detailed mapping of what disclosures of Cirik (and Cirik’s provisional) on which it relies. Based on the current record, we see nothing incorrect in Petitioner identifying multiple parameters as making up the “first configuration parameters for beam failure recovery.” As the plain language of claim 1 makes clear, there are “parameters”—plural—not just one. We also find, on the current record, that those “parameters” are not limited by the claim to only “random access parameters.” The disputed claim limitation uses the transitional phrase “comprising” in reciting the “first configuration parameters for beam failure recovery.” As courts have explained, “[i]n the parlance of patent law, the transition ‘comprising’ creates a presumption that the recited elements are only a part of the device, that the claim does not exclude additional, unrecited elements.” Crystal Semiconductor Corp. v. TriTech Microelectronics Int’l, Inc., 246 F.3d 1336, 1348 (Fed. Cir. 2001). Claim 1 recites “first configuration parameters for beam failure recovery, comprising first random access parameters.” Thus, we agree with Petitioner that the “first configuration parameters for beam failure recovery” can—but are not required to—include additional parameters (i.e., in addition to the recited “first random access parameters”). Here, we find that, on the current record, Petitioner has shown sufficiently Cirik’s “one or more configuration parameters [that] may indicate the maximum number of beam of beam failure counter” is such a parameter for beam failure recovery. Ex. 1005 ¶ 307; Ex. 1003 ¶ 52. As Petitioner correctly notes, these are substantially the same as examples of “first configuration parameters for beam failure recovery” identified in the ’128 patent. See Pet. 15 (citing Ex. 1001, 63:9–12, 41:65–67; Ex. 1003 ¶ 53). Petitioner has further sufficiently shown that Cirik also discloses that as part of its beam failure recovery process, Cirik initiates certain “random access (RA) procedures.” Id. (citing Ex. 1005 ¶ 152, 161–164, Figs. 13A– C). As part of these RA procedures, we agree that Cirik discloses sending a configuration message including “one or more random access channel (RACH) parameters.” Id. (citing Ex. 1005 ¶¶ 151–154, 156, 161; Ex. 1003 ¶¶ 54–55). As Petitioner explains, “[t]he RACH parameters included in a configuration message can include indications of ‘one or more Physical RACH (PRACH) occasions available for transmission’ of a random-access preamble message and information for determining the power level of the transmission.” Id. (citing Ex. 1005 ¶¶ 153, 154). Cirik explains this “contention-free random access procedure . . . may be initiated for beam failure recovery.” Ex. 1005 ¶ 162; see also Pet. 20–23 (discussing in detail in the context of limitation [1b] the RA procedures for beam failure recovery in Cirik). We note that nothing in the claim language requires that the first configuration parameters must be received in a single message. Indeed, the claim language explicitly permits “one or more messages.” Thus, there is nothing improper about the Petitioner identifying multiple messages as including the “first configuration parameters for beam failure recovery” (i.e., Cirik’s configuration parameters that indicate the maximum number of beam failures and Cirik’s configuration parameters for random access processes used in connection with beam failure recovery), as Patent Owner suggests. Prelim. Resp. 4 (“But at no point does Petitioner assert that the configuration message for first random access parameters is included within the ‘one or more configuration parameters [that] indicate the maximum number of beam failures’ that it identifies for the ‘first configuration parameters’ limitation.”). Accordingly, for purposes of institution, we find that Petitioner has shown sufficiently that Cirik discloses this limitation.” slip op. at 15

      “c) Conclusion Petitioner’s contentions are supported by the testimony of Dr. Akl and are persuasive based on the current record. See Pet. 7–28; Ex. 1003 ¶¶ 58–83. Petitioner has shown a reasonable likelihood of prevailing on its assertion that claim 1 is unpatentable over Ying and Yang. Accordingly, we institute review “on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” See 37 C.F.R. § 42.108(a). 4.

      “3. Claim 1 a) Petitioner’s Contentions Petitioner argues that Ying and Yang collectively teach all of the limitations of claim 1 and a person of ordinary skill in the art would have been motivated to combine their teachings, with a reasonable expectation of success. Pet. 11–28. As to the combination of references, Petitioner asserts that a person of ordinary skill in the art “would have been motivated to include configuration parameters for both the NUL and SUL carriers, as taught in Ying, in a single DCI, as expressly depicted in Yang, to coordinate both normal uplink (NUL) and supplemental uplink (SUL) transmissions in a mobile communication environment.” Id. at 12 (citing Ex. 1003 ¶¶ 58–59). According to Petitioner, “[t]he combination involves coordinating both carriers already operating in the mobile communication environment by implementing Ying’s DCI example (e.g., in Listing 6) to provide cancellation indications for both the normal uplink (NUL) and the SUL in one DCI,” achieving the “predictable result” of “improv[ed] communication capacity, speed, flexibility, and/or efficiency.” Id. at 12–13 (quoting Ex. 1004, col. 1, ll. 31–41). Petitioner also alleges various other reasons for why a person of ordinary skill in the art would have been motivated to combine the references’ teachings in that manner, including “reduced communication overhead,” simplification of the UE’s decoder operation, and the need to choose from only two options (i.e., “using one DCI to encode both NUL and SUL carriers . . . or using two DCIs”).

      “Patent Owner responds that Petitioner fails to show that the 3GPP-38.213-CR “document sent to [the] 3GPP email list on November 3 was available to non-3GPP members by November 5, 2019” (the alleged critical date for the ’944 patent). Prelim. Resp. 3 (emphasis omitted); see Pet. 10. According to Patent Owner, the listserv archive of emails cited by Mr. Rodermund “only shows that the November 3, 2019 email is available now—not that it was uploaded within a day of when the original email was sent”—and Mr. Rodermund provides only his uncorroborated opinion that uploads were “automatic” and “immediate.” Prelim. Resp. 5–6 (citing Ex. 1008 ¶¶ 43–63, 72–80). Patent Owner also contends that the November 2, 2019, metadata only relates to creation of 3GPP-38.213-CR and does not support Petitioner’s contention that the email was immediately uploaded. Id. at 6. Finally, Patent Owner argues that whether the subject matter of 3GPP-38.213-CR was discussed at the 3GPP meeting in October 2019 is “irrelevant,” given the date of the metadata, and has no bearing on whether the document itself was later publicly accessible. Id. at 6–7. Assessing the evidence of record collectively, however, we are persuaded that Petitioner has shown a reasonable likelihood that 3GPP-38.213-CR was publicly accessible from the ETSI email archive before November 5, 2019. Given his many years of experience with ETSI, in particular his responsibilities pertaining to management of documents like change requests, and as the “list owner” “responsible for managing and administrating” several email exploder lists, Mr. Rodermund appears to be well-qualified to testify to the matters in his declaration.

      “measurement value, as Jover teaches.” Id. (citing Ex. 1005 ¶¶ 39–40; Ex. 1003 ¶¶ 115–30). Among other reasons, Petitioner contends that a POSITA would have been motivated to combine “to improve the accuracy and reliability of the beam failure determination.” Id. at 37 (citing Ex. 1003 ¶¶ 115–30). Petitioner further contends that a POSITA would have had a reasonable expectation of success because “it would have been straightforward for a POSITA to implement Jover’s triggering condition in Xia’s method.” Id. at 38 (citing Ex. 1003 ¶¶ 115–30). After considering Patent Owner’s arguments, which we address below, we agree with Petitioner at this stage that the combination of Xia and Jover renders obvious limitation [1e]. Patent Owner first argues that Jover “does not cure the deficiencies of Xia because Jover’s threshold condition for an increase in BER is not used for triggering a transmission of the first and second radio signal.” Prelim. Resp. 20. Just like Xia, Patent Owner contends, Jover discloses no “causality between the threshold being exceeded and transmitting the first and second radio signal.” Id. at 21. This argument does not undermine Petitioner’s showing at this stage because Petitioner relies on Xia, not Jover, for the claimed “triggering the transmission,” or “causality,” as Patent Owner calls it. See Pet. 36–38. That is, Petitioner relies on Jover for the triggering condition and on Xia for the actual triggering. See id. Patent Owner’s argument attacking the references individually is unpersuasive. See In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of refences.”). Patent Owner next contends that one of ordinary skill in the art would not have combined Xia and Jover “since Jover is directed to the opposite objective of the ’113 Patent or Xia.” Prelim. Resp. 21. That is, Patent Owner asserts, Jover teaches away from the disclosed methods. Id. at 22. Patent Owner explains, “Jover provides no attempt to improve the beam strength, but rather ignores it through beam sweeping or nullif[ies] it, in contrast to the purpose of the ’113 Patent.” Id. at 22–23. At this stage, Patent Owner’s argument is insufficient to undermine” slip op. at 15

First, Patent Owner contends that “indexes of antenna port groups with RSRP measurement values higher than a certain threshold are not a sequence of ratios,” but rather, just an identification of antenna port groups. Id. (emphasis added). We disagree, on this record. The flaw in this reasoning is that the claim does not require the first proportional sequence to be a sequence of ratios. Rather, the claimed “first proportional sequence” merely “corresponds to . . . ratios.” Thus, Patent Owner’s argument that the indexes “are not a sequence of ratios” is not commensurate with the scope of the claim.

Thus, the control component requires a microprocessor and memory with algorithmic structure including a timing algorithm or similar coding for creating a control output signal that flips to control the direction of current flow through a coil (e.g., coil 514, Fig. 5, coil 626, Fig. 6), where the coil is structure that corresponds to the recited “driving component,” as noted above.10 We adopt the District Court’s conclusion in the Apple litigation that the “control component” structure itself does not require an H-bridge switch, but only requires that the processor generates the “d” inputs configured to operate a switch or other circuit; and further that the structure does not require does not require computing initial default values as specified in step 702 of Figure 7A (i.e., values not specified by a user).

The claims only require the control component to control the power supply to cause oscillation at a specified frequency and amplitude, but do not require the frequency value to be generated before the amplitude value, or vice versa.” slip op. at 17

The parties’ proposed levels of ordinary skill are substantially similar.

      “CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“[A] determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.” (citing In re Etter, 756 F.2d 852, 859 (Fed.

Apple IPR, Paper 10 (institution decision); see also Apple IPR, Paper 2 (the “Apple Petition”). Petitioner here challenges the same claims and asserts the same grounds of unpatentability as those on which we instituted the Apple IPR. Compare Pet. 2, with Apple Petition 1; see also Mot. 1 (asserting the instant “Petition is substantively identical to Apple Inc.’s petition (‘Apple Petition’) in the Apple IPR, including that it relies on the same expert declaration,” and asserting “the same grounds presented in the Apple IPR”). As indicated, Petitioner also relies on the same declarant as did the petition in the Apple IPR. Mot. 1; compare Ex. 1003 (Hannaford Declaration), with Apple IPR, Ex. 1003 (same). Because the grounds of unpatentability in the instant Petition are identical to those in the Apple IPR and for the same reasons stated in our Decision to Institute in the Apple IPR, we institute inter partes review in this proceeding on the grounds presented in the Petition.

Mot. 1, 4. Petitioner represents that “joinder will not negatively impact the Apple IPR trial schedule” and “expressly consents to the existing trial schedule.” Id. at 10; see also id. at 7 (“Proceeding with a consolidated inter partes review would avoid potential inconsistency, promote efficient review of the same claims for the same patent under the same grounds, and would result in a final written decision without delay.”). Petitioner also represents that as “long as Apple remains in the joined IPR, Nintendo remains in a limited ‘silent understudy’ role that does not actively participate in the IPR.” Id. at 8. The record supports Petitioner. In addition, the final written decision in the Apple IPR is due to issue on or before October 15, 2025, with the Oral Hearing complete and no further briefing due. See IPR 2024-00807, Paper 15 (Oral Hearing Transcript); Paper 18, 2–3. Therefore, as Petitioner argues, joinder by Petitioner will have little or no impact on the trial schedule in the Apple IPR. On the other hand, if the Board denies joinder, Petitioner submits that it “intends to file a separate petition for IPR (‘Second Petition’) that includes grounds in addition to some (or all) of the grounds in the Apple IPR.” Mot. 14.” slip op. at 10
