“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

“C. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b).

“Further, because Bowen’s disclosed barrier height is outside the claimed range, Petitioner relies on Soukup’s purported teaching of a barrier height of “about 0.33 eV” and contends that a person of ordinary skill in the art would have been motivated to “achieve” that barrier height for the MgO barrier of Bowen’s device. Id. at 34–36. The data that Petitioner relies on from Soukup for the “about 0.33 eV” barrier height, though, was determined using the slope of an Arrhenius plot, not Simmons’ formula. Ex. 1028, 3229 (Abstract), 3231–33, Table I. In Soukup, apparent barrier heights for the samples were determined using (1) the slope of an Arrhenius plot, and (2) the zero-field intercept of the straight line logI versus V1/2 plot. Id. at 3229 (Abstract), 3230–32, Fig. 3, Table I. Reproduced below is Table I of Soukup, as annotated by Patent Owner (Prelim. Resp. 39): Annotated Table I of Soukup includes the results of analyses of sample test data, with the column highlighted in yellow showing the barrier heights obtained by a zero-field intercept method and the column highlighted in blue showing barrier heights obtained from the slope of an Arrhenius plot. See Ex. 1028, 3233; Prelim. Resp. 38–39. Dr. Bokor testifies that “Soukup disclosed that Simmons’ formula was used to approximate tunnel barrier height” and “[o]ne of skill would have understood the ‘height and the bias dependence of the insulator potential-energy barrier’ [referenced in Soukup] included the tunnel barrier height.” Ex. 1024 ¶¶ 145–147 (quoting Ex. 1028, 3229; citing Ex. 1024 ¶¶ 45–49). We do not find this testimony persuasive. Although Soukup refers to “Simmons’ model” and the Simmons 1963 paper in its “Introduction,” it does not teach any calculation using Simmons’ formula to obtain a barrier height within the claimed range. See Ex. 1028, 3229, 3236 n.1; Prelim. Resp. 63. Soukup plainly recognizes that there are methods of calculating barrier height other than Simmons’ formula, and discusses at length its calculations using two such methods: the Arrhenius plot method and the zero-field intercept method. See, e.g., Ex. 1028, 3229 (Abstract) (“These results . . . indicate a potential barrier height of about 0.72 eV when determined from the zero-field intercept of the straight line logI vs V1/2 plot and about 0.33 eV when obtained from an Arrhenius plot.”), 3232–33. Petitioner does not address whether the 0.33 eV barrier height it relies on from Soukup (determined using the Arrhenius plot method) would still be within the claimed range if calculated using Simmons’ formula. See Prelim. Resp. 63. Nor does Petitioner rely on any values from Soukup’s disclosure that would be used as the variables in Simmons’ formula—Petitioner relies solely on Bowen. See Pet. 39–42. Thus, Petitioner’s argument that Bowen and Soukup teach a barrier height within the claimed range, obtained using equation (1), is not persuasive. See id. at 34–42.” slip op. at 17

“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.

“At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim.

See Prelim. Resp. 32–33. Dr. Woods testifies that microprocessor 212 receives the measured current and the input voltage of the charging device, and, from those values, calculates power in.

We note, however, the following guidance for proceedings before the Board as it relates to claim construction: The Board will determine the claim construction based on the record of the proceeding at issue. Thus, as in a district court proceeding, the parties should point out the specific portions of the specification, prosecution history, and relevant extrinsic evidence they want considered, and explain the relevancy of any such evidence to the arguments they advance.

“At this stage, we find that Petitioner has provided sufficiently articulated reasoning with rational underpinning to support combining Neufeld and PCI Bridge Spec’s teachings in the manner Petitioner does. See that one of ordinary skill in the art “would have recognized that the local bus 166 could have been implemented as a PCI bus” in light of Neufeld’s teaching that “[t]he implementation details of the internal local bus 166 are a matter of design choice.” Ex. 1005 ¶ 56; Pet. 39. And we credit Dr. Meldal’s testimony that one of ordinary skill in the art “would have understood that a PCI bus would have been acceptable for the relatively (with respect to, e.g., the front side bus for Neufeld’s CPU 3) low bandwidth that would be necessary for Neufeld’s remote management controller 116.” Ex. 1003 ¶ 134. The bus leading to the remote management controller 116 (the PCI bus 16/PCI bus 172) being a PCI bus supports the acceptability of using a PCI bus for the internal local bus 166. Id.; see also KSR, 550 U.S. at 417 (“When there is a design need or market pressure to solve a problem [(i.e., choosing a bus protocol)] and there are a finite number of identified, predictable solutions, [(i.e., a finite number of known protocols)] a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103.”). At this stage, we find unavailing Patent Owner’s argument that “there is no need for [one of ordinary skill in the art] to look elsewhere for guidance on implementing Neufeld’s ATB 170 as a bridge to the local bus 166” because Neufeld teaches that the implementation details of the internal local bus 166 are a matter of design choice. Prelim. Resp. 48. Rather, as we discuss above, one of ordinary skill in the art would have found it obvious for the internal local bus 166 to constitute a PCI bus, and as such would have having a bridge (the ATB unit 170) between two PCI buses. Moreover, PCI Bridge Spec also evidences the knowledge of one of ordinary skill in the art that we appropriately consider as part of our obviousness analysis. Randall Mfg., 733 F.3d at 1362–63. Thus, when one of ordinary skill in the art would have been motivated to employ a PCI bus for the internal local bus 166, the knowledge of also needing a controller should be considered. See id.; Ex. 1008, 109 (“Every bus segment in a PCI system requires an arbiter. Since a bridge creates a new bus segment, it is anticipated that an arbiter will be a common bridge feature.”); cf. Koninklijke Philips N.V. v. Google LLC, 948 F.3d 1330, 1338 (Fed.

“Upon consideration of the parties’ arguments and for the reasons explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision for the following reasons. First, the construction of “grid point” we adopt here is supported by the Specification of the ’358 patent. Namely, the ’358 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”9 Ex. 1001, 3:57–67. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 1018, 3:50–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 1028, 19 (emphasis added). We agree with the district court’s analysis. Although the ’358 patent does not explain how a generic “grid point” might differ from the described “nonuniform grid point,” we do not find this distinction pertinent to construing “grid point” in this case because neither party raises this issue. Furthermore,” slip op. at 18

“We agree with Petitioner. The pertinent disclosure from Shkedi reads: Simply stated, if a mobile telephone (at a user selected location) measures a plurality of service antenna signals and stores these with their respective service antenna identifications, then that mobile telephone (or an equivalent unit) upon observing an respective signal strengths—can reasonably conclude that it is within a predetermined proximity of the original user selected location. Ex. 1006, 8:41–48. Here, we find that the language “within a predetermined proximity of the original user selected location” refers to an area around the original user selected location. In other words, “within a predetermined proximity of the original user selected location” discloses that, instead of being exactly at the original user selected location, the mobile telephone only need be in the area or vicinity of the original user selected location. Indeed, in acknowledging “that Shkedi assumes the user is within some ‘predetermined’ distance of [the original user selected] location” (PO Resp. 33), Patent Owner effectively confirms this interpretation of Shkedi’s disclosure. That is, being within some predetermined distance of the original user selected location is equivalent to being within a circle centered on the original user selected location and having a radius equal to the predetermined distance. That Shkedi allegedly only “assumes” that the user is within the predetermined distance of the original user selected location does not detract from the fact that Shkedi’s disclosure of “within a predetermined proximity of the original user selected location” describes an area around the original user selected location.” slip op. at 34
