Accordingly, we understand that we need not reconsider our conclusion that Petitioner had demonstrated a reasonable likelihood of proving that claims 1, 2, 7–9, 11, 12, and 20–24 were unpatentable or that the merits of patentability set forth in the Petition warranted institution of inter partes review.” slip op. at 5

“The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3. Based on the record presented by the parties to date in this proceeding, no dispute exists that the disputed claim terms mean what Patent Owner says they mean in the Litigation. Accordingly, we find that, at this stage of the proceeding, it is undisputed that Patent Owner’s interpretations of the claim terms represent the “single claim construction that best captures the true meaning of the patent claim.”8 Under that claim interpretation, we” slip op. at 8

“CLAIM CONSTRUCTION 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.

“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.

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

“Cerebrum Sensor Technologies, Inc. (“Patent Owner”) timely filed a Preliminary Response. Paper 9 (“Prelim. Resp.”).1 Institution of an inter partes review is authorized by statute when “the information presented in the petition filed under section 311 and any response filed under section 313 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.” 35 U.S.C. § 314(a).

“We disagree. Positioning module 6 to face a “predetermined direction” is a form of preventing movement that falls within the scope of limitation 1b. Moreover, Yamaguchi-727 uses a method for preventing movement of its module 6 in its housing 20, silicone potting material, that is expressly recognized by the Specification of the ’421 patent when it states: “A common technique used to assist in fixturing the electrical sensor device 40 known within the automotive industry is to fill the internal cavity with a coating material such as a neutral silicone or the like for purposes of retaining placement position.” Ex. 1001, 13:56–60. Although the Specification also asserts that the sensor assemblies disclosed in the 421 patent “do not use or require the use of any such coating or filing agents or materials for any fixturing of the electrical sensor device 40,” id. at 13:61–64, limitation 1b merely requires that the “sensor device . . . is disposed within the internal cavity and attached therein to prevent movement of the device within the internal cavity,” id. at 30:25–27. Absent a persuasive argument to the contrary, we preliminarily conclude that Yamaguchi-727’s use of potting material to hold its module 6 in place within its housing 20 meets the requirements of limitation 1b. Both parties are encouraged to adduce intrinsic evidence relating to the meaning of limitation 1b at trial. For all the reasons set forth above, we find that Petitioner has established a reasonable likelihood of proving the Yamaguchi-727 renders claim 1 unpatentable as obvious. 2. Dependent Claims 2, 7–9, 11, 12, and 20–24 Petitioner identifies the portions of Yamaguchi-727 that teach the limitations introduced in dependent claims 2, 7–9, 11, 12, and 20–24, all of which ultimately depend from claim 1. Pet. 32–40. Patent Owner relies upon its argument that Petitioner’s showing for claim 1 is deficient as the reason why Petitioner’s challenge to dependent claims 2, 7–9, 11, 12, and 20–24 fails. We reject this argument for the reasons stated in Part II.C.1 above. Based on our review of Petitioner’s otherwise uncontested argument and evidence cited in support, we find that Petitioner also establishes a reasonable likelihood of proving that Yamaguchi-727 renders dependent claims 2, 7–9, 11, 12, and 20–24 unpatentable as obvious.

“Petitioner complies with the requirement of identifying “[h]ow the claim language is to be construed” by setting forth proposed interpretations of various claim terms in the table above.7 Both cases cited by Patent Owner relate to an issue presented by a petitioner’s alleged inconsistent handling of whether a claim term is subject to interpretation as a means-plus-function element under 35 U.S.C. § 112(f). Orthopediatrics Corp. v. K2M, Inc., IPR2018-01546, Paper 10 at 11 (PTAB Feb. 14, 2019); 10x Genomics, Inc. v. President and Fellows of Harvard College, IPR2023- 7 Neither party has identified any claim language that might invoke interpretation as a means-plus-function limitation, and we discern no such claim language. Additionally, we do not imply that a petitioner must always propose express interpretations for specific claim language to comply with Rule 42.104(b)(3). Rather, we only note that Petitioner has, by any measure, complied by expressly proposing interpretations for identified claim language.” slip op. at 7
