    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner

      “based on Petitioner’s first stipulation filed on December 18, 2024.15 Prelim. Resp. 13–15. Patent Owner does not address Petitioner’s updated second stipulation filed on April 8, 2025. This updated second stipulation mitigates any concerns of duplicative efforts between the district court and the Board, as well as concerns of any potentially conflicting decisions. See Sand at 12. We therefore find that this factor weighs against exercising discretion to deny institution. See id., n.5. 5. Whether Petitioner and the Defendant in the Parallel Proceeding are the Same Party Whereas Petitioner does not address factor 5, Patent Owner argues that the parties to this proceeding are both in the related district court litigation. Pet. 98–99; Prelim. Resp. 15. While it is common in IPR proceedings for the petitioner and patent owner to also be parties in a related district court proceeding, this factor weighs slightly in favor of discretionary denial. Fintiv, Paper 11 at 13–14.” slip op. at 15

    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)InstitutedInstituted

      “c) Conclusion Regarding Claim 1 Based on the current record, we determine that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 1 is unpatentable as obvious over the combination of Mazumder and Mori. Accordingly, we institute inter partes review with respect to all claims and all grounds asserted in the Petition. 5. Claims 3, 5–7, 9, 10, and 19–22 Because Petitioner demonstrates a reasonable likelihood of success in proving that at least one claim of the ’324 patent is unpatentable, we institute on all grounds and all claims raised in the Petition. See 37 C.F.R. § 42.108(a). Therefore, at this stage of the proceeding, it is not necessary for us to provide an assessment of every challenge raised by Petitioner, especially, as in this case, when Patent Owner does not separately argue those claims. See Prelim. Resp. 28–46. Those challenges, in our view, are best left for trial after full development of the record.” slip op. at 27

    • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

      “reference must be analogous art to the claimed invention. In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). For a reference to be analogous art, it must be “either in the field of the applicant's endeavor or [be] reasonably pertinent to the problem with which the inventor was concerned.” In re Kahn, 441 F.3d 977, 986-87 (Fed. Cir. 2006) (citing In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992)). “A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor's endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an inventor's attention in considering his problem.” In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992).” slip op. at 20

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “Mazumder because “the presentation of both image types would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process.” Pet. 23–24 (citing Ex. 1003 ¶ 113). Patent Owner argues that “it is hindsight to use ‘the invention to define the problem the invention solves.’” Prelim. Resp. 43 (quoting Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012); citing AT&T Services Inc. et. al. v. Innovative Sonic Ltd., IPR2024-001143 (PTAB Feb. 11, 2025)). According to Patent Owner, because neither Mazumder nor Mori teaches visual comparison of image types, the idea to improve the Mazumder-Mori combination by simultaneously displaying different image types and thus permitting visual comparison must be driven by hindsight. Id. at 44–45. But Petitioner cites evidence other than the ’324 patent to support the person of ordinary skill in the art having a desire to visually compare the different images presented in the Mazumder-Mori combination. Pet. 23–24 (citing Ex. 1003 ¶ 113). Specifically, Dr. Wolfe testifies that “the presentation of the actual images captured by the camera and the virtual images simultaneously within the user interface would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process” and that a person of ordinary skill in the art would have recognized this. Ex. 1003 ¶ 113. Thus, Petitioner has shown sufficiently for the purpose of the present decision that Mori teaches or suggests the disputed limitation of claim 1. We encourage the parties to develop the arguments and the record surrounding this issue further during the trial.” slip op. at 26

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner’s and Patent Owner’s proposed levels of skill are similar and differ in that Petitioner’s relevant degrees and corresponding two years of experience additionally includes “industrial design” and “product design” and familiarity with “electrically powered vaporizing articles, their components or the underlying technologies” where Patent Owner requires two years of experience “designing electro-mechanical consumer products or an advanced degree.” Compare Pet. 7, with PO Resp. 2. Patent Owner alleges that “Petitioner has failed to establish unpatentability under either standard,” indicating that the level of skill in the art is not a dispositive issue. PO Resp. 3. 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 ’123 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 the ’123 patent and the prior art. We note that the outcome of this Decision would be the same under Patent Owner’s proposed definition.” slip op. at 11

    • Expert testimonyPetitioner expert creditedOther

      “In this case, Mr. McAlexander meets both Petitioner’s and Patent Owner’s proposed level of skill in the art. As a result, we are persuaded Mr. McAlexander has the requisite skill and relevant expertise to offer testimony in this matter. For example, Mr. McAlexander has a Bachelor’s Degree in Electrical Engineering and far more than 2 years of experience in the electrical engineering field. Ex. 1027, 3–6, 7. In addition, Mr. McAlexander has provided expert consulting services in a wide range of technology areas involving the process and design of electro-mechanical consumer products. Ex. 1003 ¶ 5. Through one of Mr. McAlexander’s business ventures, his laboratory has “performed detailed airflow analyses, designing and constructing specialized apparatuses to emulate human breath, allowing for precise activation testing of ENDS devices.” Ex. 1043 ¶ 16. That said, a declarant’s expertise, even clothed as a skilled artisan, does not entitle a naked opinion persuasive weight. Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985). Here, Patent Owner had the opportunity to, and in fact did, thoroughly cross examine Mr. McAlexander about the purported deficiencies in his testimony. See, e.g., Exs. 2052, 2054; Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 595 (1993) (“Vigorous cross examination [and] presentation of contrary evidence . . . are the traditional and appropriate means of attacking shaky but admissible evidence.”). Therefore, to the extent Patent Owner credibly identifies deficiencies in Mr. McAlexander’s testimony or that testimony lacks factual support or is based on broad, conclusory assertions, we will assign appropriate weight. See Velander v. Garner, 348 F.3d 1359, 1371 (Fed. Cir. 2003) (explaining that it is within the Board’s discretion, as the trier of fact, to accord appropriate weight to the evidence presented).” slip op. at 12

      “Petitioner contends that the parties proposed a construction for “pressure valve,” a limitation appearing in claims 18 and 31, during the ITC investigation. Pet. 7 (citing Ex. 1001, 41:58–65). Patent Owner contends that the terms of the ’123 patent should be given their plain and ordinary meaning. PO Resp. 4. Because resolution of the issues presented in this case do not require construction of the term “pressure valve,” we do not expressly construe this claim term. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (holding that “only those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy”); see also Nidec Motor Corp. v.

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable

      “We agree with Patent Owner. To anticipate a claim, a reference “must not only disclose all elements of the claim within the four corners of the document, but must also disclose those elements ‘arranged as in the claim.’” Net MoneyIN, 545 F.3d at 1369. “The requirement that the prior art elements themselves be arranged as in the claim means that the claims cannot be treated . . . as mere catalogs of separate parts, in disregard of the part-to-part relationships set forth in the claims.” Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1325, 1332 (Fed. Cir. 2010). Indeed, the prior art reference “must clearly and unequivocally disclose the claimed [invention] or direct those skilled in the art to the [invention] without any need for picking, choosing, and combining various disclosures not directly related to each other by the teachings of the cited reference.” Net MoneyIN, 545 F.3d at 1371 (citation omitted). “[D]ifferences between the prior art reference and the claimed invention, however slight, invoke the question of obviousness, not anticipation.” Id.” slip op. at 20

      “3. Institution of Inter Partes Review As discussed above, at this stage in the proceeding, we determine Petitioner has established a reasonable likelihood that the combination of Derakhshani and Tanii teaches the limitations of claim 1 and a reasonable likelihood that Petitioner will prevail in demonstrating that claim 1 is unpatentable as obvious over Derakhshani and Tanii. Because we are persuaded that Petitioner has shown a reasonable likelihood of prevailing in demonstrating that the subject matter of claim 1 would have been obvious over Derakhshani, alone or combined with Tanii, we institute an inter partes review of all claims and all challenges raised in the Petition. See SAS Inst. Inc. v. Iancu, 584 U.S. 357, 365 (2018) (stating 35 U.S.C. § 314 “simply requires [the Director] to decide whether the petitioner is likely to succeed on ‘at least 1’ claim.

      “Patent Owner acknowledges that, in this IPR, “the time-bar is not implicated.” Prelim. Resp. 5–6. Nevertheless, Patent Owner argues that we should reach the RPI question here because other IPRs challenging different patents implicate the time bar under 35 U.S.C. § 315(b). Id. at 5–6. Patent Owner’s request effectively asks us to extend the § 315(b) time bar to implicate patents not asserted in an applicable infringement complaint. We decline to do so. The plain language of § 315(b) does not extend the time bar to any patent other than the patent subject to the instant petition: An inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent (emphasis added). Nor are we aware of any other authority which requires us to interpret § 315(b) to extend the time bar to patents other than the challenged one. Because Patent Owner admits this Petition challenging the ’910 Patent is not time barred, the treatment in SharkNinja controls. Accordingly, on this record, we need not consider whether iProov must be named as an RPI and decline to deny institution under 35 U.S.C. § 312(a)(2).” slip op. at 3

    • Skill levelDecided for patent owner

      “time it was made, we consider the level of ordinary skill in the pertinent art at the time of invention. Graham, 383 U.S. at 17. Petitioner does not provide its own definition of the level of ordinary skill in the art. Instead, Petitioner asserts: In previous litigation involving the ’881 patent – the parent patent to the ’864 patent (Fuma International LLC v. R.J. Reynolds Vapor Company, Case No. 1:19-cv-260 (M.D.N.C. 2019)) with an identical specification – Patent Owner’s predecessor-in-interest asserted that a person of ordinary skill in the art (“POSITA”) at the time of the purported invention would have had a mechanical or electrical engineering degree, industrial design degree, or a similar technical degree, or equivalent work experience, and 5 to 10 years of experience in electromechanical devices. Ex. 1007, ¶¶14-17. Pet. 11–12; see also Ex. 1007 ¶ 16 (Mr. Sturges testifying that he meets “that qualification” without affirmatively providing a definition for a POSITA). Before institution, Patent Owner stated it did not challenge this definition (Prelim. Resp. 9), and we adopted Petitioner’s proposed definition in our Decision granting institution.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “Patent Owner argues, and Petitioner does not dispute, that an aperture is a “hole” or an “opening.” See, e.g., id. at 21; see generally Reply. Patent Owner asserts that, in the proper context, the plain and ordinary meaning of a housing having an aperture is that the aperture is a hole, or an opening, on the housing structure itself. Id. at 21–22. We agree. In order for an object to have an “aperture” or an “opening,” the aperture or opening must be on the structure itself and not on a separate object that is located in the structure. This construction is in accord with the Specification of the ’864 patent, which refers to apertures in context of the structure on which they are located. See, e.g., Ex. 1001, 6:12–18 (referring to a first end comprising a first aperture), 7:11–12, 7:65–67 (stating that the wall of an airflow passageway may have apertures).” slip op. at 18

      “large obstructions that force the air flow to near the peripheral surface of the housing, render the passageway non-central. During prosecution of the ’864 patent, the Examiner rejected certain claims (i.e., dependent claims 49, 63, and 75) over Han. To overcome this rejection, the applicant argued that Han cannot meet the limitation “wherein the airflow passageway extends centrally and axially from the first aperture to the second aperture.” Ex. 1002, 273. The applicant explained that Han does not meet this limitation because Han’s shell (b) does not include a central airflow passageway and instead places the perforated component for liquid storage (9) in the middle of shell (b), thereby forcing the airflow around the peripheral surface of the perforated component for liquid storage (9).

Thus, some obstructions of a passageway render the passageway non-central; in particular those obstructions that force air to flow near the peripheral surface of the housing are large enough to render the passageway non-central.” slip op. at 22

      “lacks motivation and is plagued by improper hindsight.” Sur-reply 15–17. On the record developed during trial, we agree with Patent Owner that Petitioner has not shown by a preponderance of the evidence that a person of ordinary skill in the art would have had a reason to combine the teachings of Xia with those of Wang to arrive at the claimed limitations. Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 190 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved. Ex. 1007 ¶ 144. We credit the testimony of Dr. Singhose that using a straight passageway in Xia would have been detrimental rather than beneficial. Ex. 2022 ¶ 190. slip op. at 40

      “B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art (“POSITA”) “would have had a mechanical or electrical engineering degree, industrial design degree, or a similar technical degree, or equivalent work experience, and 5 to 10 years of experience in electromechanical devices.” Pet. 10 (citing Ex. 1007 ¶ 16). Prior to institution, Patent Owner stated that, for “the limited purpose of this Preliminary Response,” it “does not challenge the definition of a POSITA set forth in the Petition.” Prelim. Resp. 9. We adopted Petitioner’s proposed definition in our Decision granting institution. During trial, neither party disputed this definition. Upon a complete record, we see no reason to change the adopted definition.” slip op. at 9

      “Patent Owner argues, however, that this presumption is overcome in the present case, and we agree. PO Resp. 28–32. We note that, although the claims require the first aperture to be “on the first end,” the claims still require that the “housing hav[e] a first aperture.” Thus, the issue is whether the aperture must be on the housing itself or part of the housing, as well as whether the aperture is on the first end of the housing. Although “having” and “includes” are used with respect to the solution holding medium to refer to elements located inside the housing, the specification of the ’881 patent suggests that the ends of the housing are part of the housing itself, rather than located inside the housing. First, “the first end . . . can be integrated into a single assembly as part of the housing.” Ex. 1001, 6:16–17. Second, “the housing . . . may comprise the cylindrical wall and two end-caps,” or “the housing . . . may comprise the cartridge wall and a single end-cap.” Id. at 3:55–59. The only figures of the ’881 patent that depict first end 206 show it at the end of the housing rather than located within the interior of housing 202. Id. at Figs. 2, 3. Moreover, there is no requirement to construe a claim term uniformly across multiple uses in the claims when doing so would be nonsensical. Microprocessor Enhancement Corp. v. Texas Instruments, Inc., 520 F.3d 1367, 1375 (Fed. Cir. 2008). Here, construing a first element that is recited as “having” or “includ[ing]” a second element always as encompassing not only second elements that are part of the first element, but also second elements that are located within the interior of the first element, would lead to nonsensical results. Claim 2 recites an airflow passageway “having a length having a circular cross section.” Ex. 1001, 17:59–60. It would be nonsensical to interpret this claim as encompassing an airflow passageway of non-circular cross section that contains another object that has a circular cross section, and neither party argues in favor of such a reading. Similarly, claim 16 recites an “airflow passageway having an interior having a uniform cross-sectional area,” and there is no reason to interpret this claim as encompassing an airflow passageway of non-uniform cross-sectional area that contains another object that itself has uniform cross-sectional area. Id. at 19:47–48. Thus, the claims do not use “having” or “includes” consistently to refer to elements located within the interior of an object; instead, they sometimes use these terms to refer to elements that are a part of an object. See Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1030–31 (Fed. Cir. 2002) (terms should be construed based on the context of how the terms are used in the claims).” slip op. at 13

      “When we instituted trial, we preliminarily construed this phrase to encompass apertures that are located within the first end of the housing, determining on the record available at that time that “[t]he term does not require that the first aperture be located in the housing itself.” Inst.

      “2. Factor 2: ITC Final Determination Date Fintiv provides that an ITC trial date that is earlier than the Board’s projected statutory deadline for a final written decision may favor discretionary denial if the ITC is going to decide the same or substantially similar issues to those presented in the petition. Fintiv, Paper 11 at 8. The Guidance Memo further provides that “the Board is more likely to deny institution where the ITC’s projected final determination date is earlier than the Board’s deadline to issue a final written decision.” Guidance Memo 2. Here, the ITC has set the target date for its final determination to March 2, 2026. Ex. 2010, 3 (ITC Order Amending the Procedural Schedule).

      “An inter partes review may not be instituted “unless . . . the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). The Board, however, has discretion to deny institution even when a petition meets that threshold. Cuozzo Speed Techs., LLC v. Lee, 579 U.S. 261, 273 (“[T]he agency’s decision to deny a petition is a matter committed to the Patent Office’s discretion.”).

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Institution denied fintivDenied

      “trial allays concerns about inefficiency and duplication of efforts.” Fintiv, 6. However, when there is a parallel district court litigation and an ITC investigation, “district court litigation is often stayed under 28 U.S.C. § 1659 pending resolution of the ITC investigation.” Id. at 7. The fact that the parallel district court litigation is stayed is, therefore, not the focus of this Fintiv factor under these circumstances. Instead, Fintiv counsels that “the parties should indicate whether the patentability disputes before the ITC will resolve all or substantially all of the patentability disputes between the parties, regardless of the stay.” Id. at 9. Here, the parallel ITC investigation is not stayed and, as we explain below in our analysis of Factor 4, there is some overlap between the patentability disputes presented here and those presented at the ITC. Petitioner argues that the district court is “not bound to any ITC decision” (Pet. Reply 2), but as Fintiv reminds us, “even though the Office and the district court would not be bound by the ITC’s decision, an earlier ITC trial date may favor exercising authority to deny institution under NHK if the ITC is going to decide the same or substantially similar issues to those presented in the petition.” Fintiv, 8.” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “While Petitioner addresses all limitations of the challenged claims in its Petition, Patent Owner presents arguments under all three grounds raising issues with Petitioner’s challenges. For example, regarding the first ground, Patent Owner argues Okubo’s image cutout “does not represent a portion of a larger input image, but rather is the size of the image that is ‘picked up’ and recorded in the first instance.” Prelim. Resp. 12. Thus, according to Patent Owner, Okubo does not disclose “selecting sub-frames” as recited by limitation 1[D] of claim 1. Id. Regarding the second ground, Patent Owner argues that Okubo’s two-stage lens distortion correction process is limited to still images while Sokeila’s teachings relate to video images. Id. at 18–19. Regarding the third ground, Patent Owner argues that “Eder does not disclose selecting sub-frames representing portions of the input images, where the input images include fields of view captured through a lens of the camera.” Id. at 21.
