      “IV. PATENT OWNER’S MOTION TO EXCLUDE Patent Owner seeks to exclude portions of Dr. Wieselthaler’s Declaration (Exhibit 1041), portions of Mr. Crosby’s Reply Declaration (Exhibit 1042), portions of the deposition transcript of Dr. Wieselthaler (Exhibit 2028), and the exhibits “upon which that testimony is based” (Exhibits 1015, 1038, 1044, 1046, 1049, and 1050). Mot. 1. According to Patent Owner, the Motion was made “to preserve objections previously made in the record.” Id. (citations omitted). Patent Owner did not timely move to strike any of the evidence at issue as being outside the scope of reply evidence. Patent Owner asserts that because an inter partes review must be based on prior art consisting of patents or printed publications (citing 35 U.S.C. § 311(b)), the testimony of Mr. Crosby and Dr. Wieselthaler concerning “various physical devices allegedly known” to a person of ordinary skill in the art is inadmissible, along with all of the exhibits (consisting of printed materials such a journal abstracts, press releases, and papers) related to those physical devices. Id. at 3–4; see also Mot. Reply 1–4 (arguing that “devices that Petitioner’s witnesses assert were in public use prior to the claimed inventions, are not prior art that can form the basis of an inter partes review”). According to Patent Owner, Dr. Wieselthaler was unable to “link two of these physical devices to the printed prior art asserted in this [inter partes review], but those attempts fell apart during his cross examination.” Id. at 4. Patent Owner further reasons that because the evidence “cannot be the basis” of an inter partes review, it “has probable,” “is irrelevant and not admissible,” “presents substantial danger of confusing the issues, causing undue delay, and wasting time in this trial,” and “are not ‘based on sufficient facts[,] the product of reliable principles and methods[, or] ‘a reliable application of the principles and methods to the facts of the case.’” Id. at 7 (citing Fed. R. Evid. 401–403, 702) (modification in original). With regard to Exhibits 1015, 1038, 1044, 1046, 1049, and 1050, Petitioner argues, and we agree, that Patent Owner identifies no plausible legal theory for their inadmissibility based on the contention that they discuss physical devices. See Mot. Resp. 3. We also agree with Petitioner that the exhibits are not “the basis for any ground” asserted in this proceeding, and may be properly relied upon by Dr. Wieselthaler and Mr. Crosby as support for their rebuttal testimony directed to Patent Owner’s arguments disputing Petitioner’s asserted motivation to combine the prior art relied upon in the instituted grounds.

      “‘electronics for power and control’”). According to Mr. Crosby, a person of ordinary skill in the art “would have understood based on the disclosure of this setup that these speed and motor parameters were monitored by a sensor providing feedback to the controller.” Ex. 1003 ¶ 725. Mr. Crosby identifies no support for this opinion, which we give little weight to. The mere fact that Bourque’s pump used software to control speed and motor parameters does not show that Bourque used “one or more sensors” to provide feedback signals to the external control unit. Indeed, Petitioner fails to identify any evidence that Bourque used any “sensor” to monitor “speed and motor parameters.” Mr. Crosby also states that “[e]ach of the ‘ultrasonic flow probe’ and the ‘solid-state catheter-type pressure transducer’ described in [Bourque] is a ‘sensor’ as recited in Claim 33 that provides feedback signals to the external control unit (e.g., ‘electronics for power and control’ and ‘data acquisition’).” Id. ¶¶ 581, 726. Mr. Crosby’s opinion is again unsupported by the evidence, because, as explained above, there is no teaching in Bourque that either the “ultrasonic flow probe” or the “pressure transducers” used in the “in vitro characterization” studies were part of the heart assist pump device. Based on our review and consideration of Petitioner’s arguments and evidence directed to claim 11, we find that Petitioner has not shown by a preponderance of the evidence that the asserted combination of Bourque and Wampler teaches or suggests each of the limitations of dependent claim 11. We reach the same conclusion for the same reasons with regard to claim 33.” slip op. at 48

      “consequence in determining the action.” Fed. R. Evid. 401. Fed. R. Evid. 702 serves “a ‘gatekeeping role,’ the objective of which is to ensure that expert testimony admitted into evidence is both reliable and relevant.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1360 (Fed. Cir. 2008). There is no question that the disputed testimony of Dr. Wieselthaler and Mr. Crosby is relevant to the asserted motivation to combine and reliable, only whether it becomes “not relevant” or “unreliable,” in light of limited scope upon which grounds of unpatentability may be based under 35 U.S.C. § 311(b), because the testimony is based on, or supported by, knowledge of physical devices and publications discussing physical devices. Patent Owner directs us to no support for the notion that an expert’s testimony in an inter partes review must be limited to only the prior art relied upon as grounds for unpatentability and may not take into account any knowledge of, or publications concerning, other “physical devices” that would have been known to a person of ordinary skill at the relevant time.

We recognize that Petitioner appears to raise the argument that “non-prior art evidence” may be relied upon by an expert, but Petitioner also fails to identify what evidence it is referring to and that argument was not responsive to any issue Patent Owner raised in the Motion. See Mot. Resp. 5. To the extent the Parties intend “non-prior art evidence” to refer to the testimony of Dr. Wieselthaler and Mr. Crosby, we view the issue as pertaining to the weight afforded that testimony, in light of the supporting evidence relied upon, rather than one of admissibility. for the exclusion of evidence in this proceeding and deny the Motion.” slip op. at 83

      “1. “magneto coupling” Claim 1 recites, in relevant part, “a second magnetic device . . . positioned to magnetically drive rotation of the magnetically driven rotor via a magneto coupling with the first magnetic device.” Ex. 1001, 5:34–37. Claim 11 recites, in relevant part, “the second magnetic device positioned axially closer to the first magnetic device than to the magnetically driven rotor so as to magnetically drive rotation of the magnetically driven rotor relative to the one or more walls via a magneto coupling with the first magnetic device.” Id. at 6:42–48. Petitioner argues that “magneto coupling” means “a transfer of torque from one rotating permanent magnetic component to another rotating permanent magnetic component via a magnetic field.” Pet. 8–9 (citing Ex. 1003 ¶¶ 68–87). According to Petitioner, this construction is consistent with the ’879 patent, which describes “a coupling between two rotating ‘bar magnets’—a drive wheel rotates one bar magnet which causes another bar magnet (connected to a rotor) to rotate.” Id. (citing Ex. 1003 ¶¶ 54–55 (analyzing Ex. 1001, 2:28–52, 4:44–64, Fig. 2)). Patent Owner argues that “magneto coupling” should be afforded “its plain and ordinary meaning, which would encompass a magnetic coupling through both rotating magnets and the use of a rotating magnetic Owner directs us to the testimony of Mr. Leschinsky, who explains that a person of ordinary skill in the art would have understood the ’879 patent to use “magneto coupling” to generally describe “a way to couple the rotor to a drive element while sealing the two from one another and avoiding use of a direct mechanical coupling.” Ex. 2015 ¶ 67. According to Patent Owner, “Petitioner provides no recognizable basis for limiting the plain meaning of magnetic coupling to one type of magnet and excluding another type of magnet.” PO Resp. 6–7 (citing Johnson Worldwide Associates, Inc., v. Zebco Corp., 175 F.3d 985, 989–992 (Fed. Cir. 1999)). We agree with Patent Owner that Petitioner does not provide a sufficient basis for limiting the plain meaning of “magneto coupling.” That the ’879 patent describes embodiments using bar magnets does not serve to require the use of permanent magnets for the recited “magneto coupling.” See Sisvel Int’l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1236 (Fed. Cir. 2023) (quoting Phillips, 415 F.3d at 1323 (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”)). Moreover, the claim language here is not so limited. 13 Patent Owner notes that Petitioner’s grounds of unpatentability based on Wampler and Bourque depend on the disclosure only of electromagnetic drives in each reference, implying that “Petitioner does not believe its own proposed narrower construction.” PO Resp. 6; see also Pet. 8 (Petitioner alleging that in the Parallel Proceeding Patent Owner “conflates ‘magneto coupling’ . . . with a stator drive using a stationary electromagnet, instead of a rotating magnet, to rotate the rotor magnet,” and asserting that as the basis for Petitioner’s reliance on Wampler and Bourque as teaching a “magneto coupling” in this proceeding (citing Ex. 1019, 7; Ex. 1003 ¶¶ 84–87)).” slip op. at 24

In addition, we agree with Petitioner that one of ordinary skill in the art “would have found it obvious to use Parkin’s CoFeB layer in place of Bowen’s electrodes to increase TMR” in light of Parkin’s explicit teachings. Pet. 27; Ex. 1024 ¶ 133. In particular, Parkin explicitly teaches that “very high TMR values are unexpectedly found for MTJs with highly textured (100) MgO tunnel barriers but with nominally amorphous storage layers.” Ex. 1062, 18:49–51. Notably, Parkin provides that “[t]he TMR of the device of F[igure] 3A is nearly two times higher than the highest TMR ever reported in prior art devices using conventional alumina tunnel barriers.” Id. at 18:63–65; Pet. 27. And as we discuss above, Parkin teaches that Figure 3A’s MTJ may be inverted, such that the storage layer is formed beneath the tunnel barrier. Ex. 1062, 17:7–10. In addition, we agree that one of ordinary skill in the art would have had a reasonable expectation of success in modifying Bowen in the manner Petitioner proposes, as forming electrodes with CoFeB alloys was known. Pet. 28.

      “We find unavailing Patent Owner’s arguments that Bowen teaches a “radically different manufacturing process[] from the claimed invention,” and that Bowen “went to heroic lengths to provide a crystalline (001) bottom electrode that provides a template for epitaxially growing a crystalline MgO(001) layer.” PO Resp. 2 (emphasis omitted). Patent Owner describes in detail Bowen’s specific manufacturing process, including the specific structure of the MTJ manufactured, and argues the claimed invention differs. PO Resp. 30–33. These arguments are inapposite. Petitioner cites the specific teachings Petitioner relies on from Bowen, rather than adopting the entirety of Bowen’s process or MTJ. See, e.g., Pet. 21–36 (citing the portions of Bowen—that in combination with Parkin—teach claim 1).

      “A reply may only respond to arguments raised” in the patent owner response. 37 C.F.R § 42.23(b). The Consolidated Trial Practice Guide states that responding “does not mean proceed[ing] in a new direction with a new approach,” and “[w]hile replies . . . can help crystalize issues for decision, a reply . . . that raises a new issue or belatedly presents evidence may not be considered,” that is, “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Consolidated Trial Practice Guide § II.I (last updated Dec. 12, 2025) (“CTPG”), available at https://www.uspto.gov/patents/ptab/trial-practice-guide. We are not persuaded by Patent Owner’s assertions that Petitioner’s reply arguments on Parkin should not be considered. As discussed supra Section II.D.3.i above, the Petition includes the assertion that if Parkin’s CoFeB electrodes were used to modify Bowen, the MgO polycrystalline or single-crystal layer would still have the same 001 orientation. Pet. 33–34 (citing Ex. 1024 ¶ 129; Ex. 1062, 9:58–10:2, 18:49–51; Ex. 1005, 4:30–32). Petitioner’s support in the Petition references disclosures relating to Parkin’s Figure 3A (Ex. 1062, 18:49–51), which discloses a MgO(100) tunnel barrier, and the Petition also notes that the structure of Figure 3A may be inverted. Pet. 40 (citing Ex. 1062, 17:7–10). Patent Owner’s arguments, in large part, are related to Petitioner’s arguments in the Reply relating to Parkin’s Figure 11. Parkin’s Figure 11 is an embodiment where the structure of the devices of Figure 3A is inverted. See Ex. 1062, 22:29–33. We do not find that Petitioner’s arguments that are at issue in the Reply represent a new direction in its approach—the Petition is clearly based on the assertion that if Parkin’s CoFeB electrodes are used in Bowen, the device would have a MgO(001) tunnel barrier layer. Further, the Petition refers to Parkin’s disclosure that the device in Figure 3A may be inverted, which would be encompassed by the Figure 11 embodiment. Moreover, in the Institution Decision, we invited additional briefing on whether Parkin’s storage magnetic electrode was an amorphous ferromagnetic electrode, which relates to Parkin’s Figure 11 (Dec. 28–29). We are also not persuaded by Patent Owner’s argument that the Petition’s assertions do not correspond to what Petitioner argues in the Reply because they were referred to in the section pertaining to limitation 1[e]. The Petition includes a cross-reference in the limitation 1[d] discussion on the tunnel barrier layer limitation: “if Sunai’s or Parkin’s CoFeB electrodes are used as described in Claims 1[e] and 2 in this Ground, one of skill would understand that the MgO . . . would still have the same (001) orientation.” Pet. 33. Further, Petitioner’s arguments in its Reply properly respond to arguments made on contested issues. Patent Owner’s contentions on the merits in its Response are largely based upon the assertion that the modified MTJ of Bowen would not have a MgO(001) layer as claimed. See PO Resp. 4–10, 18–48. Petitioner’s reply arguments on Parkin relate to whether there would be a MgO(001) layer in its structure, so we find that Petitioner’s arguments on Parkin in its Reply (Pet. Reply 2–5) and the related evidence are appropriately responsive. slip op. at 17

      “We find that there is sufficient evidence in support of Petitioner’s assertion of the rationale to replace Bowen’s electrodes with CoFeB and anneal them. As discussed supra Section II.D.ii.2, Parkin’s Figure 11 depicts and describes a storage electrode that may be composed of amorphous CoFeB, with the formation of a MgO(001) barrier layer atop it. See Ex. 1062, 22:29–66. Patent Owner argues that Parkin’s benefits are because its CoFeB electrode is amorphous (PO Resp. 51–52), but this is not accurate. In Parkin, the CoFeB amorphous electrode crystallized at the interface layer between the barrier and the electrode. Id. at 19:6–19. Parkin discloses that higher TMRs were attributable to the crystallization of CoFeB. Id. at 18:63–19:22. Parkin also discloses that its completed CoFeB- MgOH(001)-CoFeB device was annealed with resulting high TMRs. Id. at 17:60–18:16. These disclosures provide support that one of skill in the art would have been motivated to replace Bowen’s electrodes with CoFeB and anneal to crystallize them because of the known improvements of TMR. Additionally, Parkin’s disclosures support that the results of the combination would have been predictable. That is, Parkin actually discloses an amorphous CoFeB electrode, formation of a MgO(001) tunnel barrier on the amorphous electrode, and annealing the assembly, with a resulting high TMR. Accordingly, Petitioner has provided reasoning with rationale underpinning for the motivation to combine. See KSR, 550 U.S. at 415 (“[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results”).” slip op. at 31

      “hermetically sealed” module does not encompass waterproof modules that are not airtight. First, as Petitioner admits, as a general matter, “[s]omething that is hermetically sealed is sealed so as to be airtight.” Pet. 28 (citing Ex. 1002 ¶ 103; Ex. 1010, 269); PO Sur-reply 16. Petitioner later tries to argue that the specification puts a different spin on this meaning, but still acknowledges that “[o]utside the context of the ’483 patent, a hermetic seal is sometimes equated with an airtight seal.” See Pet. Post-hearing 2–3 (citing Ex. 1002 ¶ 103; Ex. 1010, 269). Based on our review of the record, the “ordinary meaning” of “hermetically sealed” means “airtight,” and, as noted above, “airtight” is not the same thing as “waterproof.” Second, the claims support Patent Owner’s position by including dependent claims that separately claim a “hermetically sealed” module (claims 13 and 32) and a “waterproof” module (claims 15 and 34), strongly suggesting that the terms have a different scope to avoid rendering some claims redundant. See Ex. 1001, 11: 65–66, 12:3–4, 12:52–53, 12:55–56. Petitioner argues in its Post-hearing brief that claims requiring waterproof modules are “a narrower species” of hermetic seal, but fails to explain how hermetic, airtight, and waterproof seals would not fall within the scope of both claims using its approach. Pet. Post-hearing Reply 2. Petitioner’s earlier argument in its Reply also seems to cut against this position by asserting that the specification “treats hermitically sealing as conventional and equivalent to waterproofing,” with different dependent claims directed to two allegedly “equivalent” terms making little sense. Pet. Reply 14 (emphasis added). The most natural reading of the claim language suggests that “hermetically sealed” means airtight, and does not encompass modules that are waterproof but not airtight. Third, while the specification does not define “hermetically sealed” and uses “waterproof” and “hermetically sealed” in similar contexts, it does not suggest that “hermetically sealed” does not require an airtight seal consistent with its ordinary meaning. See Pet. Reply 14–15 (citing Ex. 1001, 6:47–53, 9:15–18, 10:47–50). Instead, the specification states that hermetic seals prevent water from contacting electronics, which remains consistent with Patent Owner’s position because airtight hermetic seals are also waterproof. See Ex. 1001, 6:47–53, 9:15–18. The specification also states that “[t]he module preferably houses any of the aforementioned electrical components in a substantially water-proof and wear resistant/moisture resistant environment and is preferably hermetically sealed.” Id. at 10:47–50 (emphasis added). This passage supports Patent Owner’s position by suggesting that the preferable “hermetically sealed” module goes beyond mere water resistance. See PO Sur-reply 16–17. slip op. at 16

      “Based on these undisputed points and the parties’ arguments, we agree with Patent Owner that Petitioner fails to establish that a POSITA would have been motivated to locate Howell-596’s module housing 1700, which contains its UV detection system 1500, behind a user’s ear. Petitioner never squarely addresses the fact that placing Howell-596’s UV detection system behind a user’s ear would negatively impact its performance. Pet. 31–33; Pet. Reply 17–22. As a result, even if we accept Petitioner’s arguments and evidence as to the various advantages when placing electronics behind a user’s ear, it fails to establish a motivation to combine that requires placing Howell-596’s module housing 1700, and therefore its UV detection system, behind a user’s ear. Petitioner never acknowledges the readily apparent disadvantages of placing a UV detection system behind the ear, where it may not work at all. See Pet. 31–33. Nor does Petitioner argue that, in its combination, adjustments would be made to ensure accurate operation of Howell-596’s UV detection system. See id. Similarly, Petitioner notes that both Howell-596 and Howell-833 disclose UV sensors behind the ear of a user, but those teachings do not establish that placing Howell-596’s module behind the ear would ensure proper operation of its UV detection system housed within that module. See Pet. Reply 17–22. Instead, even though Howell-596 discloses a sensor behind the ear of a user, it maintains the UV detection system in a module toward the front of the temple, away from the ear. See id. at 18–19; PO Surreply 21–22; Ex. 1003 ¶ 205 (describing UV detection system 2102), Fig. 21 (showing UV detection system 2102 toward the front of the temple). Moreover, Petitioner’s reliance on the sensor placed behind the ear of the user in Howell-596 lacks weight because that sensor merely indicates that the device “is being worn by a user,” which serves a very different purpose than Howell-596’s UV detection system, which seeks to monitor a user’s exposure to UV radiation, a central purpose of Howell-596’s eyewear. See Ex. 1003 ¶ 205, code (57). Howell-833 also employs a UV sensor behind the ear, but Petitioner does not establish that it operates any differently than the “being worn” sensor in Howell-596, and therefore does not establish that Howell-596’s UV detection system would still work for its intended purposes in Petitioner’s proposed combination.

      “The parties agree that “constrain” means to retain the module in a fixed position. Patent Owner further interprets “constrain” not to allow minor movement. This interpretation is consistent with the ’174 patent, which states, In some embodiments, the first electrical conductor may be configured to constrain or substantially constrain the electronics module. As used in this context, “constrain” may refer to when the first electrical conductor is configured to provide support (i.e. a restraining force) for the electronics module to retain the module in a fixed position within the temple. That is, the first electrical conductor may be configured to hold the electronics module in place. . . . The term “substantially constrain” is used in this context to account for some minor movement of the electronics module within the temple, but the conductor may generally hold the electronics module within the temple in place (such that it remains in an operative position). Ex. 1001, 11:50–12:3 (emphasis added). Thus, the ’174 patent distinguishes between an electrical conductor configure to “constrain” an electronics module and an electrical conductor configured to “substantially constrain” an electronics module, with the latter allowing for “some minor movement of the electronics module.” We therefore adopt Patent Owner’s interpretation of “constrain” as used in claim 1 to mean the first and second electrical conductors are configured to provide a restraining force that retains the module in a fixed position without allowing for minor movement of the electronics module.7 This interpretation also is consistent with Petitioner’s interpretation, which includes retaining the module in a fixed position within the temple.

As correctly noted by Petitioner, Brunton discloses that “the [hearing aid] units may be provided with any suitable number of contact pins and the sockets provided with a corresponding number of tubular contacts that are positioned to receive the pins and in which the pins are frictionally retained.” Ex. 1003, 3:61–65 (emphasis added). Petitioner’s witness, Dr. Feland, testifies, Frictionally retaining the hearing aid unit’s pins in the cavity means that the socket contacts couple the hearing aid unit to the temple and constrain the hearing aid unit. Brunton’s socket contacts (corresponding to the claimed first and second electrical conductors) accordingly are configured to couple the hearing aid unit (corresponding to the claimed electronics module) to the temple to constrain the hearing aid unit. Ex. 1002 ¶ 64. We credit this testimony of Dr. Feland, which is consistent with the ordinary and customary meaning of a friction-fit connection. We give less credit to the testimony of Patent Owner’s witness, Dr. Oliver. Dr. Oliver testifies that “Brunton describes a cover plate that physically secures the sockets.” Ex. 2016 ¶ 87 (citing Ex. 1003, 3:71–4:1). However, this assertion is contradicted by the very disclosure Dr. Oliver quotes in his declaration, which explains that the material of the temple retains the sockets in place: “The sockets for the transistor and unit, such as the sockets 19 and 20, may be frictionally held in the cavity or may be embedded in the material of the temple, as may be desired.” Ex. 1003, 3:71–74 (emphases added); see also Ex. 2016 ¶ 87 (quoting same). Brunton does disclose a cover plate to cover the cavity, but Brunton does not disclose or suggest that the cover plate contacts or otherwise influences the hearing aid: “In the design shown, the temple is provided with a cover plate 31 that is secured in position over the unit 77 and the transistor 29 with screws 32.” Ex. 1003, 3:74–4:1; see also Ex. 2016 ¶ 87 (quoting same).” slip op. at 27
