“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.

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.

“the PTAB will not discretionarily deny institution of an IPR . . . in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition. Petitioner’s stipulation in Exhibit 1020 satisfies the language from the Director’s Memorandum quoted above.

“any evidence of objective indicia of nonobviousness. We conclude that on balance, considering the record presently before us, Petitioner has established a reasonable likelihood of showing that the differences between the subject matter of claim 1 and the teachings of Arai and Fenwick are such that the subject matter, as a whole, would have been obvious at the time of the invention to a person having ordinary skill in the art. e. Summary as to Claim 1 For the reasons discussed above, on the present record we find that Petitioner has established a reasonable likelihood that it would prevail in showing that the combination of Arai and Fenwick teaches or suggests each element of claim 1 of the ’428 patent.

“Relying on the Declaration of Jean Renard Ward, Petitioner contends that “[a] POSITA would have been motivated to incorporate[] Fenwick’s teachings regarding automatically sending recognized words to an application into Arai because this would have furthered Arai’s purpose of having a natural, uninterrupted flow in entering characters without having to press extra keys.” Pet. 31–32 (citing Ex. 1002 ¶ 139). Petitioner concludes that the combination would have been obvious in that it would apply Fenwick’s known technique for recognizing words without additional user confirmation to Arai’s known method of performing handwriting recognition, ready for improvement, to yield the predictable result of the Arai/Fenwick combination: “recognition results are sent to an application without further user confirmation—e.g., pressing the Enter Key—and handwritten character recognition results are removed from the temporary memory such as RAM when the recognition results are sent to the application.” Id. at 32 (citing Ex. 1002 ¶ 140).” slip op. at 18

Petitioner’s stipulation (Ex. 1041) satisfies the language from the Director’s Memorandum quoted above. Additionally, we do not see an issue with ambiguity in Petitioner’s stipulation. Specifically, following joinder, this IPR (i.e., IPR2024-01068), which is based on the Petition at issue here (i.e., the Petition filed by NXP), will still be pending even though Petitioner will be joined to IPR2024-00936. Thus, the “IPR from this [P]etition” will be “pending,” which satisfies the language of Petitioner’s stipulation and precludes the actions stated therein. Further, to the extent there was any potential ambiguity, that ambiguity is resolved by Petitioner’s representations in e-mail correspondence (Exhibit 3001), as noted above.
