“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. [See Ex. 1019 at 5]. This 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.” slip op. at 29

“In sum, Petitioner maintains a narrower construction of “magneto coupling” is correct, and alleges grounds of unpatentability based on both its narrower proposed construction (a construction encompassed by the broader construction), as well as based on the broader construction that Patent Owner does not dispute. We, therefore, find no merit to Patent Owner’s argument that Petitioner’s contention “contradicts itself” or fails to present a “prima facie obviousness position.” See Prelim. Resp. 3.

“Decision we find “axially adjacent” to mean “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 adjacent to a first magnetic device as measured along a central axis. 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. See Ex. 1008, [where the magnet segments are housed within the impeller blades.] Prelim. Resp. 23 (citing Ex. 1008, ¶ 18, Figs. 3, 4, 7, 9, 11, 13, 15, 17, 19).

Dr. Bokor testifies that “as is evident from the TMR equation, . . . lowering the resistance (barrier height) for parallel spin electrons [(i.e., Rp)] compared to antiparallel [(i.e., Rap)] improved TMRs.” Ex. 1024 ¶ 169 (citing Ex. 1035, 3273) (emphasis added). Dr. Bokor’s testimony is consistent with the TMR equation above, which has Rp as the only term in the denominator, and reflects that Rp would be lowered disproportionally, or otherwise the TMR would not have “improved.” Id. It also appears to be supported by other evidence of record. See Ex. 1035, 3273 (noting the” slip op. at 17

“Finally, we note that, although Petitioner has made a sufficient showing with respect to obviousness, we are not persuaded by Petitioner’s inherency argument. See Pet. 36. Specifically, Petitioner has not established that a barrier height of 0.1–0.85 eV is necessarily present in, or the natural result of, a tunnel barrier layer having some amount of oxygen vacancy defects. See Hospira, Inc. v. Fresenius Kabi USA, LLC, 946 F.3d 1322, 1329 (Fed. Cir. 2020) (“When the prior art does not expressly disclose a claim limitation, ‘inherency may supply a missing claim limitation in an obviousness analysis.’ . . . Inherency is established in the context of obviousness when ‘the limitation at issue necessarily must be present, or the natural result of the combination of elements explicitly disclosed by the prior art.’”). Petitioner points to the ’909 patent’s statement that “[w]hen there are oxygen vacancy defects, the potential barrier height of the MgO tunnel barrier is thought to decrease (such as in the range of 0.10 to 0.85 eV; more specifically, 0.2 to 0.5 eV), which is thought to result in an increase in the tunneling current.” Ex. 1017, col. 7, ll. 19–23; see Pet. 36. Bowen, however, has “oxygen vacancy defects” in its MgO layer and “[o]xygen vacancies are naturally present in every oxide” according to Petitioner, but Bowen discloses a barrier height of 0.9 eV, which is outside the claimed range (albeit only slightly). Pet. 13, 23–24. Thus, Bowen contradicts Petitioner’s assertion that a barrier height within the claimed range of 0.1–0.85 eV is inherent when there are oxygen vacancy defects.” slip op. at 23

“B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’909 patent (2004), a person of ordinary skill in the art would have had “a Ph.D. in electrical engineering, physics, materials science, or a related field, and at least one year of experience in the research, design, and/or development of magnetic/spintronic devices, or the equivalent,” or “a Master’s degree in electrical engineering, physics, materials science, or a related field, and four years of experience in the research, design, and/or development of magnetic/spintronic devices, or the equivalent,” where “[l]ess work experience may be compensated by a higher level of relevant education, and vice versa.” Pet. 18–19 (citing Ex. 1024 ¶ 25). Patent Owner applies Petitioner’s definition of the level of ordinary skill in the art for purposes of its Preliminary Response. Prelim. Resp. 17. Based on the record presented, including our review of the ’909 patent and the types of problems and solutions described in the ’909 patent and cited prior art, we agree with Petitioner’s proposed definition of the level of ordinary skill in the art and apply it for purposes of this Decision.” slip op. at 9

“combination of Bowen and Sunai teaches limitation 1[e]. Petitioner asserts, as an initial matter, that a person of ordinary skill would have been motivated to combine Bowen with Sunai because “CoFeB was known to increase TMR compared to CoFe.” Pet. 35. Dr. Bokor provides supporting testimony relying, in part, on reported research publications. Ex. 1024 ¶ 135. For instance, Dr. Bokor refers to Cardoso, which reports that the use of CoFeB-based junctures had improved TMRs compared to CoFe-based junctions. See Ex. 1061, Abstract (“CoFe-based junctions (R x A ~ 500 Ω.μm2) have lower TMR (~35%) and larger Hf (~5–6 Oe) and Hc (~12–14 Oe) [compared to CoFeB-based junctions].”). Wang also discloses that the use of CoFeB offered benefits including “a higher TMR value.” Ex. 1055, 2269–70. Additionally, Hosomi discloses that when a “ferromagnetic layer” is “comprised of a CoFeB alloy,” it “exhibits a larger TMR ratio.” Ex. 1056 ¶ 39. At this juncture, because of this evidentiary support, we find persuasive Dr. Bokor’s testimony that one of ordinary skill in the art would have been motivated to use an CoFeB alloy as disclosed in Sunai in Bowen. Patent Owner argues the motivation to combine Sunai and Bowen is flawed because Sunai, Wang, and Hosomi disclose the use of amorphous CoFeB only and not CoFeB in a crystalline form. See Prelim. Resp. 25–26, 28–29. While Sunai, Wang, and Hosomi disclose the use of amorphous CoFeB, Petitioner relies on these references to only provide support that one of ordinary skill in the art would be motivated to use a CoFeB alloy because of enhanced TMR performance due to the alloy. See Pet. 35–37; Ex. 1024 ¶¶ 135–137. We find that, on this preliminary record, the evidence provides sufficient support for Petitioner’s assertion that one of ordinary skill in the art would have been motivated to use CoFeB as taught in Sunai in Bowen because Sunai, Wang, and Hosomi, as well as Cardoso, provide support that the use of CoFeB improved electrode performance. Petitioner separately asserts that it would have been obvious to one of ordinary skill in the art to then crystallize the CoFeB electrode of the combination, which we discuss in more detail below.” slip op. at 19

We do not address the anticipation challenge at this time. “Petitioner does not offer any showing on any motivation to modify Figure 9 of Haddad138 to change the configuration from a FSI to BSI architecture.” Id. at 8. On this record, Patent Owner’s argument does not undermine Petitioner’s persuasive showing. As Petitioner argues (Pet. 29), Haddad138 teaches that its “present disclosure” (which would include the Figure 9 disclosure) can be adapted for a front side illumination (FSI) or back side illumination (BSI) configuration. Ex. 1012 ¶ 48. The express teaching of Haddad138 provides motivation to modify Figure 9 of Haddad138. Patent Owner also argues that Petitioner “offers no showing that a POSITA would be able to modify the embodiment of Figure 9 to be back side illuminated with a reasonable expectation of success.” Prelim. Resp. 9. Patent Owner’s argument again does not undermine Petitioner’s persuasive showing. Petitioner cites Haddad138 expressly teaching a FSI or BSI configuration. Pet. 29 (citing Ex. 1012 ¶ 48).
