“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

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.

“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. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed.

“Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim.

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.

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.

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.

“1. Principles of Law In an inter partes review, the petitioner bears the ultimate burden of persuasion to show unpatentability, which never shifts to the patent owner. Dynamic Drinkware LLC v. National Graphics, Inc., 800 F.3d 1375, 1379– 1380 (Fed. Cir. 2015). “However, when a patent owner attempts to antedate an asserted prior art reference, the patent owner takes on a temporary burden of production.” Medtronic, Inc. v. Teleflex Innovations S.À.R.L., 68 F.4th 1298, 1303 (Fed. Cir. 2023) (citing Dynamic Drinkware, 800 F.3d at 1378– 79)). “Once that burden is met, the burden shifts back to the petitioner.” Id. “[A] patent’s claims are not entitled to an earlier priority date because the patentee claims priority. . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120,” including a written description in the earlier-filed application that satisfies § 112. In re NTP, Inc., 654 F.3d 1268, 1276–77 (Fed. Cir. 2011) (citations omitted)); see also Research Corp. Techs., Inc. v. Microsoft Corp., 627 F.3d 859, 870–71 (Fed. Cir. 2010). “[T]he hallmark of written description is disclosure,” and “the test [for satisfaction of the written description requirement] requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The written description “must ‘clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed,’” and “reasonably” convey to those skilled in the art “that the inventor had possession of the claimed subject matter as of the filing date.” Id. (alteration in original). Stated another way, “one skilled in the art, reading the original disclosure, must immediately discern the limitation at issue in the claims.” Purdue Pharma L.P. v.

“3. Reason to Combine Petitioner contends it would have been obvious to a person of ordinary skill in the art to combine (1) Eckhardt’s method of disinfecting skin using any light source that emits light capable of sterilization or disinfection, with (2) Sosnin’s KrCl or XeBr light sources, which generate photons having a wavelength of 222 nm and 282 nm, respectively. Pet. 21– 22 (citing Ex. 1003 ¶¶ 40, 81; Ex. 1004 ¶¶ 31, 69; Ex. 1005, 1547). Petitioner contends a person of ordinary skill would have been motivated to combine the teachings of Eckhardt and Sosnin for several reasons: (1) Eckhardt’s teaching of using any light source capable of sterilization or disinfection, and specifically “narrow spectrum light (e.g., a line spectrum)” would have suggested to a person of ordinary skill in the art to incorporate other well-known germicidal UV light sources like Sosnin’s, and both references teach that their light sources kill bacteria; (2) a person of ordinary skill would have implemented Eckhardt’s high-level disclosure of using UV- C light to disinfect skin with Sosnin’s 222 nm excimer lamp because Sosnin’s lamp’s wavelength is within the range of 220 to 310 nm suggested by Eckhardt; (3) the effectiveness and relative safety of directing UV-C light of 222 nm on bare skin for disinfection was already understood by persons of ordinary skill in the art, even though there was general caution against exposing skin to excessive UV radiation. Pet. 22–24 (citing Ex. 1003 ¶¶ 40, 81–92; Ex. 1004 ¶¶ 5, 31, 69, 70; Ex. 1005, 1545–47; Ex. 1011 ¶¶ 28, 40; Ex. 1013 ¶ 8; Ex. 1015, 2:22–67; Ex. 1016, 2:23–26; Ex. 1017, 58).” slip op. at 25

“with our analysis of the effective filing date of original claims 12–18 that Patent Owner does not meet its burden to demonstrate the inventor’s possession in the ’626 provisional of generating photons of at least two single line wavelengths. Having considered the additional disclosures of the ’626 provisional Patent Owner points to in its RMTA (see RMTA 9), we find that none of these disclosures describe using both 222 nm and 254 nm single line wavelengths. See Ex. 1008 ¶¶ 8, 12, 27, claim 9; Ex. 2047, 6–9. For example, the recitation of “apparatus that consists of a NUV source, ESP, ozone generator, mercury lamps, and humidifier with controls as defined in claims 3–8 and any combination therein” in claim 9 of the ’626 provisional generally identifies various sources that may be used, but would not have indicated to a person of ordinary skill that the inventor had possession of generating single line wavelengths of 222 nm and 254 nm. Mr. Lawal’s testimony supports this finding. Ex. 1053 ¶¶ 1–12. Accordingly, we determine that Patent Owner does not meet its burden to demonstrate written description support for generating photons of at least two single line wavelengths, in claims 19–25 of its RMTA.19 Because Patent Owner has not satisfied the statutory and regulatory prohibition against introducing new matter in the revised proposed substitute claims, we deny the RMTA as to claims 19–25. 35 U.S.C. § 326(d)(3); 37 C.F.R. § 42.221(a)(2)(ii).

- Parallel petitionsDecided for petitioner
“The Trial Practice Guide states that “one petition should be sufficient to challenge the claims of a patent in most situations.” CTPG 59. “Two or more petitions filed against the same patent at or about the same time . . . may place a substantial and unnecessary burden on the Board and the patent owner and could raise fairness, timing, and efficiency concerns.” Id. (citing 35 U.S.C. § 316(b), which is identical to 35 U.S.C. § 326(b)). Although rare circumstances may necessitate two petitions, “the Board finds it unlikely that circumstances will arise where three or more petitions by a petitioner with respect to a particular patent will be appropriate.” Id. To help the Board determine whether multiple petitions are necessary, the Trial Practice Guide further instructs a petitioner filing multiple petitions challenging the same patent to explain “the differences between the petitions, why the issues addressed by the differences are material, and why identifies one petition that satisfies petitioner's burden under 35 U.S.C. § 314(a).” CTPG 59–60. Additionally, the Trial Practice Guide instructs the patent owner to “clearly proffer any necessary stipulations,” where the patent owner asserts that “the differences identified by the petitioner are directed to an issue that is not material or not in dispute.” Id. at 61. The patent owner may, for example, “seek to avoid additional petitions by proffering a stipulation that certain claim limitations are not disputed or that certain references qualify as prior art.” Id. In light of the particular facts before us, we decline to exercise our discretion to deny the Petition pursuant to 35 U.S.C. § 324(a) on the basis of the filing of two parallel petitions. In particular, we recognize that the two petitions do not include duplicate attacks on the basis of unpatentability over prior art, but rather break the issues into two distinct parts—prior-art based unpatentability challenges, in PGR2023-00012, and 35 U.S.C. §§ 101 and 112 challenges here. The usual considerations of fairness, timing, and efficiency do not weigh in favor of exercising our discretion to deny institution. In particular, the petitions were filed concurrently, which means that Petitioner did not gain a timing advantage that might otherwise occur if the petitions were filed serially. Additionally, the proceedings can be coordinated, and a similar or common schedule can be adopted. To the extent that Patent Owner argues (see Prelim. Resp. 55–56) that Petitioner was attempting to avoid providing a single stipulation that (upon institution) Petitioner will pursue neither section 103 grounds on certain art, as per the stipulation offered in PGR2023-00012, nor section 101 and 112 grounds as per the stipulation here (see Pet. 49), discretionary denial of this Petition would not provide such a stipulation. Because we institute both here and in is equivalent to our best understanding of Patent Owner’s desired stipulation “tak[ing] into account” the two Petitions. Accordingly, based on the particular facts and circumstances before us, we decline to exercise our discretion to deny the instant Petition under § 324(a) on the basis of the Petitioner’s filing of multiple petitions.” slip op. at 14
