“stipulation would only eliminate the District Court’s consideration of Haddad204. Despite the stipulation, the District Court would still have to consider invalidity of every claim the Petition addresses and would still have to consider the Alie, Baggenstoss, and Park references. Cf. Stellar at 4 (“Petitioner’s invalidity arguments in the district court are more expansive and include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot.”). In other words, “Petitioner’s stipulation does not ensure that [this proceeding] would be a ‘true alternative’ to the district court proceeding.” Id. at 3–4.

As Petitioner and its expert explain, a person of ordinary skill in the art would have been motivated to modify Figure 5 of Alie into a BSI device because BSI devices allow more incident light to reach the semiconductor layer, resulting in more light being absorbed, an increase in the quantum efficiency, and an improvement in the signal to noise ratio.

In order to distinguish Uniyal, the claims have been amended to recite a single static set of ultrasound RF data in a single frame of the tissue area.

“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.

In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The level of ordinary skill in the art is also reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this Decision, we adopt the assessment offered by Petitioner, as it is consistent with the ’403 patent and the asserted prior art.” slip op. at 6

“Importantly, Soukup indicates a different relationship between the amount of oxygen vacancy defects in the barrier layer and the barrier height, depending on which method is used. Specifically, Soukup explicitly found that “[t]he apparent barrier height determined from the zero-field intercept went up for increasing oxygen pressure [(i.e., less oxygen vacancy defects)] and the barrier height determined from the Arrhenius plot went down.” Ex. 1028, 3229 (Abstract) (emphasis added).15 That disclosure is reflected in Table I, where Soukup shows the results for three fabricated samples with increasing oxygen pressure during MgO deposition. Id. at 3233. Patent Owner provides another annotated version of Table I below (Prelim. Resp. 45): 15 Soukup’s conclusion appears to refer to the trend of the respective increasing or decreasing barrier heights values under the two different mathematical analyses methods. Annotated Table I above shows (in red) that the barrier height decreases as oxygen vacancies increase (i.e., as the oxygen pressure admitted during MgO deposition, shown in the PO2 column, decreases) using the zero-field intercept method, and shows (in blue) that the barrier height increases as oxygen vacancies increase (i.e., as the oxygen pressure admitted during MgO deposition decreases) using the Arrhenius plot method. Prelim. Resp. 45. In other words, Petitioner’s alleged inverse relationship is present for the zero-field intercept method, but not for the Arrhenius plot method. See id.; Pet. 37–38. “The barrier height cannot both increase and decrease with more oxygen vacancy defects,” and Petitioner does not attempt to reconcile or explain Soukup’s disparate teachings. See Prelim. Resp. 45 (emphasis omitted). We agree with Patent Owner that Petitioner is inconsistent in relying on one method as allegedly teaching a barrier height within the claimed range, while at the same time relying on the other method for a motivation under its obviousness theory. Prelim. Resp. 45–49. If a person of ordinary skill in the art would have understood that the Arrhenius plot method was the appropriate method for determining barrier height, as Petitioner argues in asserting that Soukup teaches a barrier height of 0.33 eV, that person would have understood that “the barrier height increases as oxygen vacancies increase” (in blue above), and Petitioner’s obviousness theory of adding oxygen vacancies to lower Bowen’s barrier height is incorrect. See id. at 47. If, however, a person of ordinary skill in the art would have looked to the zero-field intercept method, that person “would have understood that all of Soukup’s tested samples . . . had barrier heights” (in yellow above) “above the claimed range of 0.2–0.5 eV.” See id. at 48. Petitioner cannot have it both ways. Based on the record before us, Petitioner has not shown sufficiently” slip op. at 23

“As discussed above, Petitioner fails to explain why one of ordinary skill in the art would have selected the barrier height value it relies upon. And given the disparity of Soukup’s barrier tunnel values under the different methods of analyses, the reference is, at best, ambiguous as to which values are accurately representative of barrier height. Additionally, the evidence supports that the apparent barrier height value that Petitioner relies upon (“about 0.33 eV”) will be a different higher value, so the actual value of the barrier height is uncertain. Accordingly, we do not find that Petitioner has met its burden to sufficiently demonstrate that a person of ordinary skill in the art would have understood Soukup to teach or suggest the claimed range of limitation 1[e] in that there is insufficient evidence presented that supports that the selected Soukup barrier height value represents an accurate value.” slip op. at 20

“Thus, the cited teachings of Sunai support Patent Owner’s position that, even if adding boron into a ferromagnetic layer of CoFe results in a higher TMR as taught by Sunai, the addition suppresses crystallization. As to the issue of the teaching of the BCC structure of the alloy, not only does Petitioner’s challenge applying Bowen and Sunai fail to demonstrate a teaching or even a suggestion of a CoFeB alloy with a BCC cited by Petitioner does not either. Only one of Petitioner’s cited pieces of underlying evidence refers to a BCC lattice structure, Parkin, but Parkin’s BCC structure is disclosed with respect to a CoFe layer, and not a CoFeB layer. Ex. 1062, 18:55–59 (“The simple cubic crystalline MgO layer thus provides a template for the formation of a thin crystalline ferromagnetic layer which has the bcc structure of CoFe and is oriented in the same (100) direction as the MgO layer.” (emphasis added)).” slip op. at 12
