      “The parties’ proposed levels of ordinary skill in the art are similar, although Patent Owner proposes two years of experience along with a bachelor’s degree whereas Petitioner proposes “significant” experience. Patent Owner also proposes an alternative with more extensive experience in lieu of a bachelor’s degree. Although we find Petitioner’s proposed qualifications acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of ordinary skill necessary to understand and implement the teachings of the ’504 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

      “actuators and the remote control of fluid handling devices, including the receipt with the user-interface module of “a user command to actuate an actuator via a presented control interface” (limitation [18.7]) and “account authorized to send commands to remotely control fluid handling devices” (limitation [18.11]). We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18. Kahn discloses that “the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance.” Ex. 1005, 10:62–67. Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively. Rather, the disclosure indicates that the communication unit 112B includes on-site alerts and that the local (non-remote) communication unit 112B can be interfaced with the control valve.” slip op. at 18

      “Petitioner contends that one of ordinary skill in the art “would have had at least a Bachelor’s degree in electrical engineering, material science, chemical engineering, or an equivalent field, as well as at least 2 to 3 years of academic or industry experience in the recycling or processing of lithiumion batteries. Additional formal education focusing on processing of lithium batteries may substitute for practical experience and additional practical experience can substitute for less education.” Pet. 10–11. Patent Owner does not contest this definition of a person of skill in the art. See Prelim. Resp. 11. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as, on the present record, it appears consistent with the ’463 patent and the asserted prior art.

      “distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

      “obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

      “2026. This date is nearly five months prior to the date on which the final written decision would be due if trial were instituted in this proceeding. And, even if we assume Petitioner’s alleged February–March 2026 trial date, this date too is several months prior to the projected final written decision deadline. As such, it is unlikely that a final written decision in this proceeding would issue before trial in the district court, unless the trial was delayed or rescheduled for a later time. Thus, we find this factor weighs in favor of exercising our discretion to deny institution. See ARM Ltd. v. Daedalus Prime LLC, IPR2025-00207, Paper 10 at 2 (May 16, 2025) (Before the Office of the Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office) (exercising discretion to deny institution with the same relative timing between district court trial and final written decision deadline).” slip op. at 13

      “Such an approach is inconsistent with the Supreme Court’s statements that in an inter partes review, “the petitioner is master of its complaint,” and “the petition [is] the centerpiece of the proceeding.” SAS Inst., Inc. v. Iancu, 584 U.S. 357, 363, 369 (2020). “It is of the utmost importance that petitioners in IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016) (quoting 35 U.S.C. § 312(a)(3)). In contravention of these principles, Petitioner’s approach improperly shifts the onus to Patent Owner or the Board to identify and parse out erroneous, and purportedly non-essential, citations to Saxonov and piece together an argument based on the remaining citations. As we stated in the Decision, we decline to assume this task. See Dec. 20. Finally, in the Request, Petitioner attempts to “show[] how Ground 6 is fully supported by undisputed prior art material.” Req. 6. This attempt is improper.

      “Upon request for rehearing, we assess a decision on institution “for an abuse of discretion” (37 C.F.R. § 42.71(c) (2020)), which occurs when a “decision was based on an erroneous conclusion of law,” “clearly erroneous factual findings,” or “a clear error of judgment.” PPG Indus. Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567 (Fed. Cir. 1988) (citations omitted). The burden of showing a decision should be modified lies with the party challenging the decision. 37 C.F.R. § 42.71(c) (2020). The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. Id. Thus, a request for rehearing is not an opportunity merely to disagree with the Board’s assessment of the arguments or weighing of the evidence, or to present new arguments or evidence.

      “Neither party contends that any claim terms require an express construction to resolve the present controversy. Pet. 8 (“For purposes of this Petition only, Petitioner does not believe any terms require a formal construction.”); see generally Prelim. Resp. Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied. Accordingly, we do not construe any claim terms expressly because express constructions are not necessary to resolve the controversy before us. See Realtime Data, 912 F.3d at 1375.” slip op. at 12

      “We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89. But, as noted above, Jin does not disclose an element referred to as a “pilot parameter” and it is not clear what element Dr. Min intended to identify in Jin.8” slip op. at 18

      “For purposes of this institution decision, and based on the present record including the disclosure in the ʼ473 patent, we apply Petitioner’s definition of the level of ordinary skill in the art at the time the invention was made, consistent with pre-AIA section 103(a). See Pet. 9–10. We determine this level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ʼ473 patent and the prior art of record. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the prior art itself may reflect an appropriate level of skill in the art).” slip op. at 8

      “Petitioner’s representation of the problem as merely converting Petrauskaite’s disclosed mol% of triglycerides into wt% of triglycerides with simple calculations represents a form of prohibited reliance on hindsight. See Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012) (hindsight to use the invention to define the problem the invention solves); see also Ecolochem, Inc. v. Southern Cal. Edison Co., 227 F.3d 1361, 1372 (Fed. Cir. 2000) (”Defining the problem in terms of its solution reveals improper hindsight in the selection of the prior art relevant to obviousness.”). “[W]hen someone is presented with the identical problem and told to make the patented invention, it often becomes virtually certain that the artisan will succeed in making the invention.” Mintz, 679 F.3d at 1377. Here, Petitioner urges that one of ordinary skill in the art need merely convert mol% of triglycerides in a specific fat blend into wt% of triglycerides in the specific fat blend. See Pet. 14–15 (“[T]he wt% of Petrauskaite’s fat blends can easily be calculated based on the generally available prior art knowledge of fatty acid compositions of palm stearin and soybean oil.”). Petitioner’s reasoning says no more than that a skilled artisan, once presented with Petrauskaite and prior art knowledge, “would have understood that they could be combined, but that is not enough.” PersonalWeb Techs., LLC, v. Apple, Inc., 848 F.3d 987, 993 (Fed. Cir. 2017) (that two references could be combined does not imply a motivation to pick out those two references and combine them to arrive at the claimed invention). Our reviewing court instructs that indicating that a skilled artisan could have made modifications to arrive at the claimed invention does not establish that a person of ordinary skill would have made such modifications. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” (citing InTouch Technologies, Inc. v. VGO Communications, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014)). Petitioner attempts to check the “would have been motivated to modify Petrauskaite” box with testimony from its declarant, Dr. Maragoni. See Pet. 37–38. Such testimony includes [C]ombining such prior art elements according to known methods would have yielded nothing more than predictable results. A POSITA would naturally have turned to these references to understand Petrauskaite’s references better. Ex. 1003 ¶ 178. [T]he corresponding wt% of Petrauskaite’s fat blends] was readily-available and well-known in the art. Id. at ¶ 181. [T]he available information [on characterizations of oils and fats] is voluminous. Id. at ¶ 182. See Pet. 38. We find that such testimony fails to explain why the skilled artisan would have been motivated, without hindsight, to take the steps to reproduce the claimed invention, and to be conclusory, at best. On this record, we detect the taint of impermissible hindsight bias in” slip op. at 14

For purposes of this Decision, we find that the ’222 patent and the cited prior art references reflect the appropriate level of skill at the time of the claimed invention and that the level of appropriate skill reflected in these references and the ’222 patent is consistent with the definition of a person of ordinary skill in the art proposed by Petitioner.

      “Petitioner argues that “the challenged claims are invalid under their plain and ordinary meaning.” Pet. 5. Petitioner further contends that “[t]he scope of the plain and ordinary meaning of certain claim terms must at least encompass the disclosure and accompanying illustrations in the ’222 patent.” Id. at 6 (citing no legal support for its proposition). Petitioner also refers to how Patent Owner applied certain “terms” and “other features to Petitioner’s product” in its district court complaint against Petitioner. See id. at 7–8 (citing Ex. 1007, 7–8; Ex. 1003, ¶¶ 53–57). Patent Owner does not address claim construction and does not dispute the meaning of any claim term in regard to Petitioner’s contentions. See generally Prelim. Resp. Accordingly, in view of the issues we address below, we apply the plain and ordinary meaning of claim terms and further determine that it is not necessary to address the express interpretation of any claim term.
