RulingsFinal written decision- 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

“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.

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.

“B. Discretionary Denial Based on Hulu The Hulu decision held that “[b]ecause the patent claims already stand invalid, it is unnecessary to institute another proceeding to review them for patentability under other grounds.” Hulu at 2. The decision reasoned that “[i]n the event the Federal Circuit reverses the district court’s decision, Petitioner may raise such invalidity arguments in the district court on remand.” Hulu at 3 (remanding the panel’s institution decisions and denying institution). The Hulu rationale is grounded in the statutory estoppel provisions of 35 U.S.C. § 315(e) that apply only to a “final written decision;” statutory estoppel does not prevent a petitioner from raising the same invalidity grounds in district court if the petition is denied. See Intuitive Surgical, Inc. v. Ethicon LLC, 25 F.4th 1035, 1041 (Fed. Cir. 2022) decision.”). Even if inter partes review is instituted but later terminated with respect to a petitioner, e.g., after settlement, no statutory estoppel attaches to the petitioner, a real party in interest, or privy. See 35 U.S.C. § 317(a) (“If the inter partes review is terminated with respect to a petitioner under this section, no estoppel under section 315(e) shall attach to the petitioner, or to the real party in interest or privy of the petitioner, on the basis of that petitioner’s institution of that inter partes review.”). Thus, discretionary denial would not eclipse Petitioner’s ability to assert invalidity of the Challenged Claims in the District Court litigation. The Petition explains that the District Court granted a Motion to Dismiss and found all of the Challenged Claims to be patent ineligible under 35 U.S.C § 101. 130 Pet. 2 (citing Ex. 1025, 10, 14; DKR Consulting LLC v.

“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.

“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
- Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalTerm construed patent owner constructionDecided for patent owner
“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). Id. at 273–274. The examiner relied on this argument in determining that the applicant had overcome an earlier rejection. Id. at 195. 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

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

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. Dec. 16. We invited the parties to “address [the] construction of this term during trial,” id., and, on the full record developed during trial, we reach a different conclusion.” slip op. at 10
