“With respect to Patent Owner’s assertions about word count limits, the Patent Trial and Appeal Board Consolidated Trial Practice Guide November 2019 (“Consolidated TPG”) states that “deleting spacing between words, or using excessive acronyms or abbreviations for word phrases, in order to circumvent the rules on word count, may lead to a party’s brief not being considered.” Consolidated TPG, 40 (citing Pi-Net Int’l, Inc. v. JPMorgan Chase & Co., 600 F. App’x 774 (Fed. Cir. 2015)). As the basis for denying the Petition, Patent Owner alleges “undue prejudice.” Prelim. Resp. 76. Patent Owner, however, did not raise with the Board, prior to filing its Preliminary Response, any concern with the manner in which Petitioner formatted its Petition. As a result, Patent Owner did not avail itself of the opportunity to seek relief to address any alleged undue prejudice short of denying the Petition through, for example, an increase in the word count for its own brief.

“axially adjacent.” In particular, Petitioner argues in connection with mapping cited art to challenged claims for the Wampler and Akamatsu asserted grounds that “a magnetic element sealed within a rotor is . . . ‘axially adjacent.’” Pet. 20 n.6. Petitioner fails to point to any intrinsic evidence to support this construction. Rather, Petitioner alleges that Patent Owner took this position in the parallel litigation in a chart mapping claim 1 to accused products. Id. (citing Ex. 1019,6 5–7). Petitioner does not explain how Patent Owner’s chart supports Petitioner’s construction here. See id. at 6 Petitioner identifies this exhibit as “Exhibit 13 of Complaint, dated November 27, 2023,” which comprises a claim chart mapping accused products to claim 1. when “a magnetic element [is] sealed within a rotor,” it necessarily means being “axially adjacent,” as Petitioner alleges. See Ex. 1019. Rather, we agree with Patent Owner that this chart instead labels product components that are adjacent to one another as measured along a central axis. Prelim. Resp. 21 (citing Ex. 1019, 6–7). In addition, we agree with Patent Owner that “[t]his [mapping] is in accordance with the plain and ordinary meaning of the claim terms and does not suggest that any component ‘sealed within’ another component would categorically be axially adjacent thereto.” Id. We note that Petitioner applies the plain and ordinary meaning of “axially adjacent” for other asserted grounds, arguing that components which are adjacent to one another along a central axis are “axially adjacent.” E.g., Pet. 55–57. Accordingly, we find, for purposes of this Decision, that the plain and ordinary meaning of “axially adjacent” is being adjacent to one another as measured along a central axis, and does not mean a magnetic element sealed within a rotor.

“would have found it obvious to include Wampler’s “techniques related to its axially aligned inflow tube” in the HeartMateIII device taught by Bourque. Pet. 81–88. Petitioner argues that Wampler teaches an arrangement for which “[g]ood anatomic compatibility is possible . . . fitting well between the apex of the heart and the adjacent diaphragm.” Id. at 83 (quoting Ex. 1008 ¶ 76) (alterations in original). Petitioner reasons that applying Wampler’s arrangement to Bourque combines old elements performing known functions yielding expected results. Id. at 83–84. According to Petitioner, a person of ordinary skill in the art would have known from Wampler that an axial inflow, as taught by Wampler, would have improved blood flow for the device of Bourque by eliminating the flow restrictive elbow in Bourque. Id. at 84 (citing Ex. 1003 ¶¶ 648–649; Ex. 1007, 2; Ex. 1008 ¶¶ 75–76). Petitioner contends that Bourque recognized certain components, including inflow components, were the cause of clinical troubles, and that Wampler “taught how to eliminate these components that caused clinical troubles–using the inlet to also ‘serve[] as the inflow canula.’” Id. at 85–86 (citing Ex. 1003 ¶¶ 741–747; Ex. 1007, 1, 5; Ex. 1008 ¶¶ 75–76). Petitioner also argues that a person of ordinary skill in the art would have understood Wampler’s arrangement would have reduced “rates of infection” by avoiding placement of the pump in a preperitoneal pocket person of ordinary skill in the art “would have adhered to the express teachings of [Wampler], which focused on ‘[g]ood anatomic compatibility’ so that the device ‘fit[s] well between the apex of the heart and the adjacent diaphragm,’ eliminating the need for a peritoneal pocket dissection associated with increased rates of infection.” Id. at 86–87 (citing Ex. 1003 ¶¶ 651–654; Ex. 1008 ¶ 76) (second and third alterations in original). Petitioner reasons that a person of ordinary skill in the art would have had a reasonable expectation of success because the asserted combination of Bourque and Wampler “would ‘fit[] well between the apex of the heart and the adjacent diaphragm’ due to the pump’s ‘development as a compact’ device and the existence of several similar LVADs that fit well at that position.” Id. at 87 (citing Ex. 1003 ¶¶ 652–655; Ex. 1007, 5). Lastly, Petitioner argues that the asserted combination would have been obvious to try, because “there were a finite number (i.e., two) [of] options for LVAD implantation: the device would be implanted at a preperitoneal pocket, or at the cardiac apex.” Id. at 87–88 (citing Ex. 1003 ¶ 656). At this stage, we find Petitioner’s arguments persuasive, and find that Petitioner has provided sufficiently articulated reasoning with rational underpinning to support combining Wampler and Bourque’s teachings in the manner Petitioner does.” slip op. at 20

“Magnetic Device” and “Magnetically Driven Rotor” along a “Central Axis”. Ex. 1019, 6. We find nothing in Exhibit 1019 that defines “axially adjacent” to mean “a magnetic element sealed within a rotor,” as Petitioner alleges. In this regard, Patent Owner argues as follows: Exhibit 1019 contains no mention of “a magnetic element sealed within a rotor” or a contention that such a configuration would represent an “axially adjacent” orientation of such components. Instead, [in Exhibit 1019], Patent Owner illustrates a Petitioner product and labels components identified as the claimed magnetically driven rotor and first magnetic device that are adjacent to one another as measured along a central axis.

“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).

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.

See Pet. 24–25. In opposition, Patent Owner argues, and we agree on the current record, as follows: Wampler does not teach or suggest “a magnetically driven rotor . . . axially adjacent to a first magnetic device” based on its imbedding of permanent magnets 88 in the impeller 74 because these components are not adjacent to one another as measured along the central axis of the device. Instead, the magnet segments 88 and impeller 74 are aligned with, and overlap, one another as measured along the central axis in Wampler’s configuration.

“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. During trial, Patent Owner also adopted this definition. PO Resp. 10–11. Upon a complete record, we see no reason to change and we maintain the agreed upon definition of a POSITA.” slip op. at 12

“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). 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

“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

“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

“Decision we find “at a position axially adjacent” to mean at a position “adjacent to one another as measured along a central axis.” Petitioner does not contend or show in the Petition that Wampler teaches a magnetically driven rotor coupled to a first magnetic device at a position adjacent to one another as measured along a central axis. See Pet. 26–28. In opposition, Patent Owner argues, and we agree on the current record, as follows: Wampler cannot teach or suggest a first magnetic device that is at a position axially adjacent to a magnetically driven rotor based on the positioning of its magnet segments 88 and impeller 74 because these components are not adjacent to one another as measured along the central axis of the device. Instead, the magnet segments 88 and impeller 74 are aligned with, and overlap, one another as measured along the central axis based on the disclosed configuration where the magnet segments are housed within the impeller blades.” slip op. at 26

“We find no sufficient support for Petitioner’s assertion that “a magnetic element sealed within a rotor is ‘at a position axially adjacent to the magnetically driven rotor.’” Pet. 26. Moreover, we find Patent Owner’s definition of the claim language reflects its plain and ordinary meaning and is consistent with the disclosure of the ’356 patent (which illustrates only a “magnetically driven rotor” positioned adjacent to a “first magnetic device” as measured along a central axis). See Ex. 1001 Fig. 2. It is also consistent with the construction Petitioner appears to contend is the correct construction, as applied by Petitioner in, for example, it’s contentions based on the asserted combination of Bourque and Wampler. See Pet. 61–62 (relying on Bourque’s teaching of a rotor and magnetic device adjacent to one another as measured along a central axis with regard to the “axially adjacent limitation” and not on Wampler’s magnets embedded in the impeller at the same location along a central axis). Accordingly, we find, for purposes of this Decision and based on the current record, that the plain and ordinary meaning of “at a position axially adjacent,” as shown by Patent Owner, is at a position “adjacent to one” slip op. at 25
