“Patent Owner asserts that the preamble of independent claim 1, 16, and 20 reciting “a deodorant stick” is limiting” as it provides antecedent basis for the recitation of “said deodorant stick being free of an aluminum salt” for each independent claim. PO Resp. 7–10. Patent Owner also points to dependent claims 6–9 as relying on the preamble reciting “a deodorant stick” as antecedent basis for claim elements. Id. at 9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 19 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick).

“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

“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.

“415 F.3d at 1314): “a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen” (claim 1) and “a first set of layers including silicon and hydrogen” (claims 9 and 15). Ex. 1001, 10:41–49, 10:65–11:4, 11:17–12:5. As the parties agree, these recitations are broadly worded. See Pet. 14 (describing the recitations of the claims as “broad” and directed to “layers of any material that has both ‘silicon and hydrogen’”); PO Resp. 42 (describing the claims as “simply specifying physical layers including silicon and hydrogen in them”), 44 (describing the disputed terms as “open-ended claiming of layers including hydrogen and silicon”). Despite this broad language, Patent Owner contends that we must read “layers including silicon and hydrogen” in conjunction with other limitations in the claims reciting a “near infrared bandpass filter.” PO Resp. 35–37 (citing Ex. 2001 ¶¶ 65–66). For purposes of our analysis, we limit “layers including silicon and hydrogen” to only materials suitable for NIR bandpass filters, as suggested by Patent Owner. We next examine the rest of the intrinsic evidence. The specification of the ’794 patent does not contain language that generally describes “layers including silicon and hydrogen.” Instead, the specification describes only layers of hydrogenated silicon: its abstract is directed to an “optical filter” that “includes a filter stack formed of hydrogenated silicon layers” (Ex. 1001, code (57)); the technical field of the invention is described as “relat[ing] to optical filters including hydrogenated silicon layers and to sensor systems comprising such optical filters” (id. at 1:20–23); the summary of the invention describes “the present invention” as an optical filter or sensor system “comprising” “a plurality of hydrogenated silicon layers” (id. at 2:57–3:19); and the detailed description begins with a hydrogenated silicon (Si:H) layers” (id. at 4:19–20). The specification only mentions silicon and hydrogen separately with respect to the disclosed sputter-deposition system “used to produce the hydrogenated silicon material.” Id. at 4:35–5:61, 7:10–19. In particular, the specification describes how “cathode 430 includes a silicon target 431, which is sputtered in the presence of hydrogen (H2), as well as an inert gas such as argon, to deposit the hydrogenated silicon material as a layer on the substrate 420.” Id. at 4:44–47. The specification also describes how altering the hydrogen flow rate in the deposition process affects the optical properties of hydrogenated silicon produced by the deposition system. See id. at 5:1–61. But the only end product described from the sputter-deposition process using silicon and hydrogen is hydrogenated silicon. See id. at 4:35–5:61, 7:10–19. As such, the specification does not provide any indication of materials beyond hydrogenated silicon that are within the scope of “layers including silicon and hydrogen.”” slip op. at 15

“hydrogen” defines a genus. The test for providing a written description that supports a genus claim is whether the description provides “either a representative number of species falling within the scope of the genus or in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). “Regarding whether common structural features must exist between a claim and a putative priority disclosure, those features must constitute the near-entirety of the structures being compared.” Regents of the Univ. of Minnesota v. Gilead Scis., Inc., 61 F.4th 1350, 1358 (Fed. Cir. 2023). Yet the patentees only disclosed hydrogenated silicon as a possible species. Indeed, the specification focuses on a singular example of a sputterdeposition system that is used to produce an improved hydrogenated silicon material. See Ex. 1017 ¶¶ 36–38. Patent Owner cites this deposition process as written description support for “the claimed layers containing silicon and hydrogen.” See PO Resp. 44. But this example supports only how to make hydrogenated silicon and does not include any indication about what other materials would be within the scope of the claimed genus. Under these circumstances, the specification’s disclosure of a single species is not an adequate number to show possession of the entire genus of “layers including silicon and hydrogen.” Beyond the disclosure of the sputter-deposition process for producing hydrogenated silicon, Patent Owner does not identify—and we cannot discern—any other examples of a “structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Ariad, 598 F.3d at 1350.

“set of layers includes oxygen.” Ex. 1001, 10:41–49.

Pet. 7–8. Patent Owner contends that this is a typographical error and “wherein” was intended. Prelim. Resp. 8 n.2. Petitioner asserts that “each of the challenges presented in this Petition” addresses “adding a third set of layers with oxygen on a second side of a substrate.” Pet. 8.

“However, Patent Owner’s arguments regarding the combination are directed towards a bodily incorporation of structures described in the references, rather than the combination of their teachings proposed by Petitioner. In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.”); In re Keller, 642 F.2d 413, 425 (CCPA 1981). Given the teachings in each reference and our direction that an ordinarily skilled artisan is a person of ordinary creativity, we find, on this preliminary record, that Petitioner has adequately shown that an ordinarily skilled artisan would have applied Lairson’s teachings regarding a short-pass filter with Erdogan or Tsai-133’s teachings concerning filter layers on both sides of a substrate used to form a bandpass filter. KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”). Petitioner’s proposed combination does not involve adding the exact layers taught in Erdogan and Tsai-133 on the second side of the substrate to Lairson’s short-pass filter on the first side of the substrate. Pet. 33–34, 36– 39. Rather, Petitioner proposes, in one example, using the same materials for filter stacks on both sides of the substrate. Id. at 37–38. Thus, Patent Owner’s arguments that adding the second-side layers disclosed in Erdogan and Tsai-133 to the first-side layers of Lairson is not responsive to Petitioner’s proposed combination. Additionally, on the present record, we credit Petitioner’s declarant’s uncontroverted testimony that Lairson does not explicitly describe a bandpass filter with a long pass filter, and thus that one of ordinary skill would have looked to Erdogan and Tsai-133 for the technique of using a long-pass filter on the other side of the substrate. Id. at 34–37 (citing Ex. 1002 ¶¶ 152, 158). On the present record, and for the purposes of institution, Petitioner sufficiently shows that the combination of Lairson and either Erdogan and Tsai-133 teaches a near infrared band pass filter comprising a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen, and a second set of layers on the first side, wherein the second set of layers includes oxygen. Additionally, on the present record and for the purposes of institution, Petitioner sufficiently sets forth its showing with respect to the motivation to combine the teachings of Lairson with those of Erdogan or Tsai-133 as it proposes.” slip op. at 21

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner
“embodiments that operate with a low frequency driving signal in a double-ended configuration, Patent Owner did not recite “low frequency” or “double-ended” in its claims and instead chose the broader term “first driving mode.” See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. 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.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed. Cir. 2004).” slip op. at 7
