Petitioner, however, refers to Parkin’s disclosure that only “a portion of the storage layer 175” is crystallized after annealing. Id. at 17–18 (citing Ex. 1062, 18:51–55) (emphasis added). Petitioner also relies upon Parkin’s “thin crystalline ferromagnetic layer” that is crystallized to teach limitation 1[d]. Id. at 18 (citing Ex. 1062, 18:55–59; Ex. 1024 ¶¶ 131–132) (emphasis added). Dr. Bokor additionally testifies that it is “Parkin’s ‘thin crystalline ferromagnetic layer’ of CoFeB” that meets the “entirely crystallized” requirement of limitation 1[d]. Ex. 1024 ¶ 132. Parkin, however, states that a thin crystalline ferromagnetic layer is formed, but “the bulk of storage layer 175 remains amorphous.” Ex. 1062, 18:55–60 (emphasis added). Petitioner fails to reconcile how its assertions that the first and second ferromagnetic layers, which are mapped to the totality of layers of 115 and 175, meet the limitation that the first and second ferromagnetic layers are each “entirely crystallized” when Petitioner relies only a thin layer, that is, a portion, of the 115 and 175 layers for the teaching that the respective layers are entirely crystallized. Put another way, Petitioner’s mapping is inconsistent: Petitioner relies upon the full depth of certain “layers” of Parkin for the teaching of the ferromagnetic layers, but then only relies upon thin portion of that depth for the assertion that the “layers” are entirely crystallized.” slip op. at 16

    “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. Petitioner cannot have it both ways. Based on the record before us, Petitioner has not shown sufficiently” slip op. at 23

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

    “geographic region.” The ’752 patent describes polling specific sub-regions of the network for a PRU. Ex. 1001, 2:12–15, 7:22–34. As Mr. McAlexander testifies, “[a] PRU may choose to instruct the network to relay certain information to mobile units in a specific geographic region. That information would then be appended to the geographic boundary information and beamed in the specified geographic region.” McAlexander Decl. ¶ 49 (quoting Ex. 1001, 10:19–23) (alteration in original). For example, a nearby boundary can be polled for the locations of nearby wireless customers within proximity of a distressed wireless customer. As described in the ’752 patent, a distressed mobile user M1 may need to find where another party might exist in that geographic region. The user could initiate a page from their PRU for the closest available PRUs that could be found in that geographic jurisdiction. Looking at FIG. 3, mobile user M1 will provide its location, latitude and longitude (x0,y0) to the closest available ground station serving area C1 or grid G1. As stated earlier, appropriate terrestrial technology will be scattered in that region to serve the PRUs in that area as shown in FIG. 1. Once a ground station picks up this signal, it sends a page for all location reporting devices in the specified boundary surrounding mobile unit M1, FIG. 3 to disclose their location.

    “We determine, on the record before us, that Petitioner does not have a likelihood of success of showing that the “prolonged” etching process that Petitioner proposes to arrive at the structure of limitation 1.6 to be “unusually simple” nor is “the technology particularly straightforward.” CN182’s etching process uses an alkali (sodium bicarbonate) solution with a concentration from 5% to 35% at a temperature of 35 to 55°C stirred for a period of 3 to 5 hours in an ultrasonic generator with power of 300 to 500 watts. Ex. 1004 ¶¶ 7–12. This is done in CN182 to create a matte structure on the inner surface of the body composed of plastic material (polyethylene terephthalate (PET)) between two antistatic coatings comprised of carbon powder layers. See, e.g., Ex. 1004 ¶¶ 5–6. Petitioner does not indicate how much time beyond CN182’s stated range of 3 to 5 hours would be required for the “prolonged” etching process it proposes to achieve a minimum depth of 2.0 μm relative to the outer carbon powder layer, nor whether a POSITA would have considered the prolonged time to be practically viable. Petitioner also does not explain what the reaction is, what its etch rate is, whether its effect would be diminished or exhausted as reactants are consumed or affected by other substances present, or whether other variables, such as the alkali concentration, temperature, or power and frequency of the ultrasonic generator, would need to be changed and how much over the course of the “prolonged” etching process.” slip op. at 30

    “The Preliminary Response argues that limitations [1A] and [1B-2] “require storing two or more shares generated from a dataset on two or more physical storage devices.” Prelim. Resp. 5. This, purportedly, is “a central feature” of the invention. Id.; see generally id. at 4–7. The relevant limitations recite: “[1A] a plurality of physical storage devices storing thereon a plurality of shares, the plurality of shares being associated with at least one session key used to secure a dataset” and a secure storage system configured to “[1B-2] generate the plurality of shares for storage on the plurality of physical storage devices by performing a securing operation on the dataset received from the client device and distributing the dataset in the shares.” See Ex. 1001 98:3–6, 98:12–15. As the Preliminary Response notes, the Federal Circuit has repeatedly held that “‘a plurality of’ means ‘at least two of.’” SIMO Holdings Inc. v. Hong Kong uCloudlink Network Tech. Ltd., 983 F.3d 1367, 1377 (Fed. Cir. 2021) (citing cases); Prelim. Resp. 5.

    “this decision we construe limitations [1A] and [1B-2] together to require storing two shares among at least two physical storage devices. Petitioner never addresses this requirement, and we find this to be a fatal flaw. According to Petitioner, Takeda teaches limitations [1A] and [1B-2] as follows: “Takeda’s technique involves dividing plaintext – which is any non-encrypted (i.e., unciphered) information – into blocks, ciphering different blocks using different ‘ciphering attributes’ (e.g., ciphering keys and/or ciphering algorithms), and outputting the ciphered blocks with the ciphering attributes.” Pet. 10; see generally id. at 10–16, 28–31, 39–40. Patent Owner responds that “Takeda’s blocks are stored together in a single storage device,” and this does not disclose or suggest storing the shares on at least two physical storage devices. Prelim. Resp. 8; see id. at 8–9 (citing Ex. 2003 ¶¶ 51–53). We agree with Patent Owner. Petitioner has not shown a reasonable likelihood that Takeda discloses or suggests storing data on physically separable storage devices. The Petition points to Takeda’s teaching that the data is “divided into blocks.” Pet. 11. As Patent Owner notes, Takeda teaches that these blocks are all stored on a single, physical device. Prelim. Resp. 8. Specifically, Takeda teaches that “[t]he ciphertext is stored in the removable recording medium 39 or the storage device 37.” Ex. 1008 ¶ 92.5 We determine that Takeda does not teach or suggest storing this data in at least two separate media, at least two separate storage devices, or at least one of each. Correspondingly, Takeda’s Figures show data blocks next to each other—i.e., on one physical device. See id. at Figs. 1–4. The Petition does not suggest that Ophir teaches storing shares among different physical storage devices. As the Petition itself notes, Ophir seems to use a single “mediator [to] provide[] secure virtual storage to data clients.” Pet. 9 (quoting Ex. 1007 Abstract) (emphasis omitted).” slip op. at 14
