      “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

      “On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding. Further submissions by the parties may include argument and evidence that would assist in the resolution of this issue at the close of trial.” slip op. at 8

      “Petitioner contends “no formal claim construction is necessary in this proceeding.” Pet. 10; Reply 1, 4. Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S. Ct. at 1359–60) is not based on construing the term “mesh layer” or “coefficient of friction,” we determine we need not construe either claim term at this stage of the proceeding.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

      “a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v.

      “Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v.

That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

      “had “a Bachelor’s Degree in a relevant engineering discipline such as electrical engineering and at least two years of relevant experience in the design and/or development of automotive electrical systems, or a Masters or more advanced degree in a relevant engineering discipline such as electrical engineering.” Pet. 6–7 (citing Ex. 1003 ¶ 46). Patent Owner does not challenge Petitioner’s definition or offer its own. In light of the record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’236 patent and the prior art of record, we determine that the definition offered by Petitioner comports with the qualifications a person would have needed to understand and implement the teachings of the ’236 patent and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “with Petitioner that the ’236 patent is not entitled to the 2014 priority date of the original application, or any date earlier than April 21, 2021, which is the filing date of the ’236 patent. Whether the Specification complies with the written description requirement calls for a comparison of the scope of the claim with the scope of the description to determine whether the inventor has demonstrated possession of the claimed invention. See Ariad, 598 F.3d 1336 at 1353; Power Oasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008). The independent claims of the ’236 patent each require (1) a load detection sensor “configured to detect presence of a vehicle battery” and (2) a reverse polarity sensor “configured to detect polarity of a vehicle battery.” Ex. 1001, 5:16–27 (claim 1), 6:7–22 (claim 13), 6:65–7:13 (claim 18), 8:1– 15 (claim 23). The Specification of the ’236 patent does not expressly disclose both a load detection sensor and reverse polarity sensor configured to perform the recited functions. Instead, the Specification identifies a single circuit, the “automatic detection module,” that “can automatically detect[] whether the load is detected” and “whether the electrode is connected with the automobile storage battery reversely.” Ex. 1001, 2:51–54. We are persuaded by Petitioner’s arguments that the disclosure of a single circuit capable of performing two functions does not demonstrate the inventors had possession of an invention that requires two separate sensors configured to perform separate functions as recited in the claims. See Ariad, 598 F.3d 1336 at 1352 (“[A] description that merely renders the invention obvious does not satisfy the [written description] requirement.”); Purdue Pharma L.P. v. Faulding Inc., 230 F.3d 1320, 1323 (Fed. Cir. 2000) (holding that “the disclosure as originally filed does not have to provide in haec verba support for the claimed subject matter at issue,” but that “one skilled in the art, reading the original disclosure, must immediately discern the limitation at issue in the claims”); cf. PIN/NIP, Inc. v. Platte Chem. Co., 304 F.3d 1235, 1248 (Fed. Cir. 2002) (finding a claim for a method involving sequential application of two chemicals was invalid for lack of adequate written description where the specification indicated that the invention was a method of applying a “composition” containing the two chemicals). For all of the foregoing reasons, we agree with Petitioner that the Specification of the ’236 patent does not provide adequate written description support for distinct “load detection” and “reverse polarity” sensors, and, therefore, the challenged claims are not entitled to a priority date earlier than April 21, 2021, the filing date of the ʼ236 patent.” slip op. at 12

      “Although Petitioner has asserted the absence of specific supporting disclosure for claims 1, 15, and 18 from the ’780, ’317, and ’977 applications and the ’155, ’587, ’601, ’977, and ’753 provisional applications, the burden to show an effective filing date (or dates) of the challenged claims prior to April 22, 2010 falls on Patent Owner here because Petitioner has asserted prior art references with earlier effective dates. In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1376 (Fed. Cir. 2016) (In an inter partes review, “a patentee bears the burden of establishing that its claimed invention is entitled to an earlier priority date than an asserted prior art reference.”). An earlier effective filing date is not presumed because, as shown in the above figure, the ’783 application is a continuation-in-part to each of the ’780, ’317, and ’977 applications that have filing dates earlier than April 22, 2010. See PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1305 (Fed. Cir. 2008) (“When neither the PTO nor the Board has previously considered priority, there is simply no reason to presume that claims in a [continuation-in-part] application are entitled to the effective filing date of an earlier filed application.”). On this record, and in the absence of the development of any contrary argument, we find that Petitioner has demonstrated sufficiently for institution that each of the asserted references are prior art to the challenged claims. The parties will have an opportunity to present their positions on the issue of the effective filing date of the challenged claims further during trial.” slip op. at 11

      “of Kronberg, discloses or suggests all of the elements of claim 6. Pet. 28–34 (citing Ex. 1002 ¶¶ 107–148). More particularly, Petitioner argues that Adest discloses the limitations of claims 6, but to the extent there is a dispute that Adest discloses the “watchdog unit” limitation [6A], a person of ordinary skill in the art would have been motivated to combine the watchdog apparatus taught by Kronberg with the solar power system taught by Adest to monitor communications between signal mechanism 420 and power modules 405 of Adest. Id. at 32 (citing Ex. 1002 ¶ 127). Petitioner further argues that the watchdog taught by Kronberg was a well-known technique for detecting malfunctions at the time of the invention, and would have been one of a number of solutions for detecting the absence of a periodic signal. Id. (citing Ex. 1002 ¶¶ 128–129; Ex. 1009, 1269). Petitioner further argues that Kronberg “suggests that its watchdog apparatus is to be used to provide ‘automatic shutdown of critical devices in case of failure,’” consistent with Adest’s objective of shutting down a power generating facility when a transmitter fails to send a communication because of, for example, a fire or theft of a photovoltaic module.

      “The limitation “means to poll the central controller to determine if an interruption of the communication is transient” presumptively invokes 35 U.S.C. § 112 ¶ 6. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). Claims subject to 35 U.S.C. § 112 ¶ 6 are construed in a “two-step process,” whereby we “first identify the claimed function,” and then “determine what structure, if any, disclosed in the specification corresponds to the claimed function.” Id. at 1351. Accordingly, our rules require that the Petition “identify the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” 37 C.F.R. § 42.104(b)(3). Further, “the corresponding structure for a § 112 ¶ 6 claim for a computer-implemented function is the algorithm disclosed in the specification” Aristocrat Techs. Austl. Pty Ltd. v. Int’l Game Tech., 521 F.3d 1328, 1333 (Fed. Cir. 2008) (quoting Harris Corp. v. Ericsson Inc., 417 F.3d 1241, 1249 (Fed. Cir. 2005)). Federal Circuit precedent requires disclosure of an algorithm in the specification for any computer-implemented function beyond “basic functions of a microprocessor.” See EON Corp. IP Holdings, LLC v. AT&T Mobility LLC, 785 F.3d 616, 623 (Fed. Cir. 2015) (“A microprocessor or general purpose computer lends sufficient structure only to basic functions of a microprocessor. All other computer implemented functions require disclosure of an algorithm.”). Petitioner does not identify any portion of the ’218 patent specification that describes corresponding structure for performing the claimed function of “poll[ing] the central controller to determine if an interruption of the communication is transient.” See Pet. 39. Accordingly, Petitioner has not identified sufficient corresponding structure for performing the function of this presumptive means-plus-function limitation.” slip op. at 22

Critically, when discussing the soft, inner layer of the inventive hard-soft-hard layer composition, the ’176 application nowhere indicates that the soft inner layer must have “a hardness of from about 60A to about 85D.” Id. ¶ 109 (discussing a prior art embodiment); see id. ¶¶ 7, 33–35, 109–110. Even if the hardness limitation of the challenged claims would have been obvious from the relied-upon disclosure in the ’176 application (id. ¶ 109), as a matter of law, that circumstance is insufficient to establish a filing date through that application. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” PowerOasis, Inc. v.

On the full trial record, we find that the earliest effective filing date to which the challenged claims are entitled is December 18, 2019, the filing date of the ’256 application from which the ’263 patent issued.
