The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

“We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

“(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

“insufficient to support the concept of alerting a user that the user is leaving a virtual environment. In so deciding, we need not address the parties’ contentions about boilerplate. Regardless of whether the sentence at 168:15–16 of the ’140 application is boilerplate, we agree with Petitioner that “there is no suggestion of the specific claimed combination.” Reply 22 (citing Ex. 1146 ¶ 82). That is, if one views the “[e]xamples herein” from Figure 6 as taking place “in computer rendered spaces (VR)” or “in partially computer rendered spaces (AR),” there is still no disclosure of alerting a user that a user is leaving a virtual environment. See Ex. 1028, 168:15–16. For instance, if Alice in the Figure 6 example mentioned above is entering a virtual car instead of a real car, Alice is still in a virtual environment. See id. at 120:13–27. Thus, relying on Figure 6 to take place “in computer rendered spaces (VR)” does not support alerting that a user is leaving those virtual spaces. See id. at 168:15–16. Petitioner also correctly identifies a problem with analogizing the Alice example to a virtual environment—namely, it would no longer make sense to give Alice an audible warning. See Reply 22 (citing Ex. 1146 ¶ 82). In the example, Alice’s earphones switch from binaural sound to mono sound when Alice enters a real car because “[t]he state where Alice is located . . . prohibits drivers from localizing sound while driving a motorized vehicle.” Ex. 1028, 120:15–18. But it would not make sense (nor does the ’140 application disclose) for a state to prohibit Alice to localize sound while driving a virtual vehicle. We therefore find compelling Petitioner’s argument, supported by the testimony of Dr. Roginska, which we credit, that there is no “disclosure that 3D audio would not be permitted in a 3D virtual space.” Reply 22 (citing Ex. 1146 ¶ 82).

According to Petitioner, the Specification does not elaborate further on the meaning of the term “information concerning prices of goods.” Id. at 11. Petitioner, thus, interprets the term to encompass scenarios in which price information is received directly or indirectly. Id. Petitioner notes that during prosecution of the ’578 patent, the Examiner rejected this limitation over prior art, stating that prior art “sends the scanned bar code information to the server,” which “then preferably returns a description of the item and information,” and “[t]his item description and price information is displayed on the telephone’s display.” Id. at 12 (quoting Ex. 1002, 231).

“Under 35 U.S.C. § 314(a), an inter partes review may not be instituted unless it is determined that there is a reasonable likelihood that the petitioner would prevail with respect to at least one of the claims challenged in the petition. After considering the parties’ arguments and evidence, and for the reasons set forth below, Petitioner demonstrates a reasonable likelihood of prevailing with respect to at least one of the challenged claims of the ’179 patent. Accordingly, we institute an inter partes review with respect to all challenged claims and grounds asserted in the Petition. 37 C.F.R. § 42.108(a) (2022). Our factual findings and conclusions at this stage of the proceeding are based on the evidentiary record developed thus far. This is not a final decision as to patentability of the challenged claims.” slip op. at 2

“The Director’s Memo provides that “[c]onsistent with Sotera Wireless, Inc.,[8] the PTAB will not discretionarily deny institution in view of parallel district court litigation where a petitioner presents a stipulation not to pursue in a parallel proceeding the same grounds or any grounds that could have reasonably been raised before the PTAB.” Director’s Memo 3.

If the PTAB institutes the pending IPR in IPR2023-01019 challenging the patentability of claims 1-20 of the ’179 patent, then [Defendants Meta Platforms, Inc., Meta Platforms Technologies, LLC, and Twisted Pixel Games, LLC] will not pursue as to the challenged claims any ground raised or that could have been reasonably raised in the IPR in the above-captioned district court litigation (No. 6:22-cv-00575-ADA). Prelim. Reply 1. Patent Owner concedes that Petitioner has filed a “Sotera-like stipulation” but argues that it is insufficient because it “leaves the door open to a duplication of efforts and the possibility of conflicting decisions.” Prelim. Sur-reply 1 (citing Ex. 1141, 4 (“This stipulation is not intended . . . to limit Meta’s ability to assert . . . invalidity under 35 U.S.C. §§ 102 and 103 not available in IPR and under 35 U.S.C. §§ 101 and 112[], regardless of whether IPRs are instituted.” (emphasis omitted))). Namely, Patent Owner argues that Petitioner’s stipulation carves out “the right to assert overlapping system art in the parallel district court proceeding,” such that institution here would not address the risk of “inconsistent outcomes between the PTAB and the district court.” Id. at 4.

See Mot. Sur-reply 1–7.

“relies on as having been allowed due to objective indicia. See Ex. 1006, 7:19–8:60. At a high level, the independent claims each recite a system for hydraulically fracturing an underground well formation comprising at least one pump driven by one or more electric motors, and a variable frequency drive to control the speed of the motor(s) and perform motor diagnostics. See id. at 7:19–33 (claim 1), 7:57–8:10 (claim 10), 8:31–51 (claim 19). None of the parent ’410 patent’s claims recites swivel connections located in the pump’s discharge piping branch as recited in claim 1 of the ’824 patent at issue here. See id. at 7:19–8:60. And, claim 1 of the ’824 patent does not recite an electric motor, or a variable frequency drive, like the parent ’410 patent’s claims do. Thus, even if the prosecution history of the parent ’410 patent establishes a nexus between Clean Fleet product(s) and one or more claims of the ’410 patent, it is not at all clear to us how this nexus might also apply to claim 1 of the ’824 patent. We reached the same conclusion in the Institution Decision. See Inst. Dec. 41.” slip op. at 72
