“In the Response, Patent Owner states that it “does not dispute” the definition of one of ordinary skill in the art proposed by Petitioner, but Patent Owner “reserves the right to address [the definition] should new issues materialize.” PO Resp. 6. Patent Owner did not address this issue in the Sur-reply. As noted in the Decision on Institution, Petitioner’s proposed definition appears generally consistent with the record, including the prior art. See Dec. Inst. 8 (citing In re GPAC Inc., 57 F.3d at 1579). We remove the phrase “at least” in both listed options, however, as that phrase adds ambiguity. Further, Patent Owner has not argued at trial that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would have understood either the challenged patent or the prior art.

“Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber). But the passage block quoted directly above (and the similar one bridging columns 5 and 6) more directly addresses the issue at hand—i.e., the scope of “form the fluid dispersion”—by using the same” slip op. at 13

“To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); TriVascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (citation omitted). Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Neither Petitioner nor Patent Owner propose explicit constructions for any claim terms. Pet. 10–11; PO Resp. 5. Based on the complete record, we need not construe explicitly any claim terms because doing so would not change the outcome of the analysis below. See Realtime Data, LLC v.

“We do not credit Dr. Anthony’s testimony, which is based on the arbitrary shading in Figure 7 (see Ex. 1002 ¶ 174), that Schröder teaches or suggests limitation 1[d] because it (1) is inconsistent with Petitioner’s reasoning for limitation 1[c], and (2) it is based on an admitted misreading of the embodiment of Schröder’s Figure 5 (see Ex. 1002 ¶ 175). As to the first item, Dr. Anthony states that “a POSITA would have been motivated to place a battery in a part of the cavity that is far from a PCB holding other electrical components because that configuration allows for better thermal management.” Ex. 1002, para. 175. The problem with this statement is that Petitioner relies on Schröder’s teaching that inlay 12, i.e., the alleged PCB, could include “other electrical components,” such as a battery to support its position that Schröder suggests placing a battery between the ring halves. See, e.g., Pet. Reply 2 (pointing to Dr. Mercier’s depo testimony that inlay 12 with “other components” is inserted between ring halves); id. at 3 (relying on Schröder’s teaching about placing components in depressions on inlay 12). So, Petitioner earlier asserts for the battery limitation 1[c] that Schröder teaches or suggests putting a battery on inlay 12 inside the ring halves, but then for limitation 1[d], Dr. Anthony testifies that a POSITA would place the battery “far” away from the inlay 12 (i.e., the alleged PCB).

“Patent Owner indicates that in the related ITC proceeding involving the ’178 patent, the Administrative Law Judge (ALJ) adopted three constructions agreed-upon by the parties in that proceeding8 and also construed two disputed terms.9 Resp. 26–27 (citing Ex. 2016, 5, 6, 14). Patent Owner agrees with Petitioner, however, that no terms need to be construed to decide the issues raised in the Petition. Id. at 27. We reviewed the constructions adopted by the ITC. Ex. 2016, 5, 6, 14. 8 In the ITC proceeding, the ALJ adopted the parties’ agreed-upon constructions that: (1) the preamble of claim 1 [a finger-worn wearable ring device] is limiting; (2) [positioned/configured to fit] within a “cavity” is [positioned/configured to fit] within a “hollow space”; and (3) [the internal housing component] “coupled with” [the external housing component] is [the internal housing component] “connected with” [the external housing component]. Ex. 2016, 5. 9 In the ITC proceeding, the ALJ construed the claims such that: (1) the internal and external housing components of claims 1, 12, and 17 enclose space and do not necessarily exclude potting material; and (2) “circumferential,” as recited in claims 1, 17, and 18, does not require a closed shape. Ex. 2016, 14, 17. These constructions are not germane to the issues we need to decide to resolve this proceeding. Thus, we agree that no explicit claim construction is necessary for this decision.

“The record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “Mestas’s batteries, layout, and other components . . . would have to be scaled down 5 to 10 times to be appropriately sized for a finger worn ring.” Resp. 64 (internal quotation marks omitted) (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Moreover, we do not credit Dr. Anthony’s testimony that miniaturization of the battery would have been “trivial to implement.” Ex. 1002 ¶ 242. Dr. Anthony admitted on cross-examination that it would not have been within the level of skill of a person having ordinary skill in the art to design a smaller version of Mestas’s battery, and that such a person would need to procure a battery of the appropriate size and specifications for implementation in a finger-ring from a battery manufacturer. Ex. 2021, 315:9–318:9. Yet Dr. Anthony had not ascertained, for purposes of his testimony, whether there was a battery available in 2013 that was appropriate to fit within the inlay space of the modified version of Schröder’s finger-ring that he and Petitioner allege would have been obvious to one of skill in the art at that time. Id. at 321:5–10. Further, we credit Dr. Mercier’s testimony that Dr. Anthony’s testimony fails to consider the differences in power requirements between Mestas and Schröder or to account for the constraints of such a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶¶ 159–160. Although large curved batteries suitable for use in a wrist band or other larger wearable device, such as shown in Mestas, were known at the time of the ’178 patent, we also have evidence that prior art “finger ring wearables up to the ’178 patent had used ‘coin’ type batteries.” Id. at 66 (citing Ex. 2018 ¶ 161). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would look to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 161. Indeed, this testimony is consistent with the other art of record that consistently shows the use of flat batteries in finger-ring devices, often stacked above and protruding from the general ring shape of the device. See, e.g., Ex. 1005 (Niwa), Figs. 22, 28; Ex. 2025 (Asada ’701 patent), Fig. 4; Ex. 1035 (Rhee), Figs. 7-1, 8-1, 8-2; Ex. 1037 (Asada article), Fig. 9; Ex. 1034 (Asada ’199 patent), Fig. 2; Ex. 1028 (Kimura), Fig. 24; Ex. 2018 ¶¶ 61–70. In fact, Oura’s first-generation ring design, released in 2015, used a Superbowl ring-type design, with the battery and other components mounted on top of the ring. Ex. 2034; Ex. 2018 ¶ 71. Based on these findings, Petitioner has not met its burden to show by a preponderance of the evidence that a person having ordinary skill in the art would have been led to modify Schröder’s finger-ring to place a curved battery between the internal and external housing components in light of the teachings in Mestas. Thus, Petitioner has not met its burden to show by a preponderance of the evidence that dependent claim 3 of the ’178 patent is unpatentable over Schröder and Mestas.” slip op. at 38

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.

“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

“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. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals.

“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.

“Level of Ordinary Skill in the Art At this stage of the proceeding, there is no dispute about the level of ordinary skill in the art. Based on the testimony of Petitioner’s declarant, we determine that a person of ordinary skill in the art (“POSITA”) would have had a four-year degree in electrical engineering, mechanical engineering, biomedical engineering, optical engineering, or related field of study, and two years of experience in academia or industry studying or developing physiological monitoring devices such as non-invasive biosensors. A POSITA would have been familiar with sensor system design and signal experience, and vice versa. Ex. 1002 ¶ 21.
