Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator.

STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c).

    “For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

    “We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58.

    “second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

    “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.

Petitioner adds that individuals with different educational backgrounds could still be of ordinary skill in the art if they have “additional experience [that] compensates for a deficit in their education and experience stated above.” Id. According to Patent Owner, a person or ordinary skill in the art, would have (i) a bachelor’s degree in chemistry, polymer chemistry, materials science, chemical engineering, or biomedical engineering and (ii) three years of experience in designing and manufacturing gel-spun UHMWPE yarns. At this level of skill, a PHOSITA would have a detailed understanding of the information provided in the Technology Background, Section II, supra, including (i) the differences between linear HDPE and UHMWPE, (ii) the history underlying Section 73.1015 and the early failures of the 1960s-era blue, melt-extruded polyethylene sutures, (iii) why the molecular orientation of polyethylene molecules leads to strong yarns in the special case of gel-spun UHMWPE, and (iv) the challenges associated with coloring gel-spun UHMWPE yarns, especially for end-use medical applications.

    “a skilled artisan would have understood that the “gel spinning” process recited in the claims requires the use of a solvent during the spinning process. Indeed, the Specification describes this term, as follows: Gel spinning is understood to include at least the steps of spinning filaments from a solution of ultra-high molecular weight polyethylene in a spin solvent; cooling the filament obtained to form a gel filament removing at least partly the spin solvent from the gel filament; removing at least partly the spin solvent from the gel filament; and drawing the filament in at least one drawing step before during or after removing spin solvent. Ex. 1001, 2:31–37. We recognize the inventor’s lexicography as dispositive with respect to the meaning of the term “gel spinning.” See Phillips v. AWHCorp., 415 F.3d 1303, 1316 (Fed.

    “Claim 1 describes gel spinning as the manner by which the filaments comprised in the claimed colored multi-filament yarn are obtained. This, on its face, is a product-by-process claim element because it describes the filament structure being obtained in a particular way, i.e., by gel spinning. See Kamstrup A/S v. Axioma Metering UAB, 43 F.4th 1374, 1382 (Fed. Cir. 2022) (agreeing with the Board that “cast in one piece” is a product-by-process claim element as it describes the structure being cast “in a particular way”). For this element to be limiting, it must impart “structural and functional differences” that distinguish the claimed product from the prior art. See Amgen Inc. v. F. Hoffman-La Roche Ltd, 580 F.3d 1340, 1365–67 (Fed. Cir. 2009). Patent Owner argues persuasively that gel spinning imparts structural and functional differences to the claimed product because the process “creates overlap between polyethylene molecules within the UHMWPE filaments that maximizes the intermolecular Van der Waals interactions, resulting in highly crystalline filaments with high tensile strength.” Prelim. Resp. 38, 22 (citing Ex. 1014, 62–66). According to Patent Owner, “the structure of the gel spun UHMWPE is substantially different from other types of UHMWPE such as compression-molded and ram-extruded UHMWPE used to make joint replacements and other orthopedic implants.” Id. at 38.” slip op. at 9

    “The express language of the claim, however, does not support using the “central axis” as the measuring point for determining if one object is laterally offset from another. For example, the term “central axis” is not used in the relevant claim phrase and the dictionary definitions of “lateral” relied upon by Petitioner and Mr. Jobin to show the ordinary meaning of the claim term do not suggest that the “central axis” is the reference point for determining whether a first object is “laterally offset” from a second object. As such, we determine that the claim language supports Patent Owner’s construction requiring that the “groove” be “off to the side” of the entire mandrel, and not merely the “central axis” of the mandrel. Prelim. Resp. 54. We must also resolve whether the entire groove is required to be laterally offset from the chamfered mandrel, or only a portion of it. On this point, the claims do not use the term “portion,” but rather specify that the “groove” is “laterally offset from the chamfered mandrel.” Ex. 1001, 14:4– 5, 15:19–20. This suggests that the entire “groove” must be offset from the “chamfered mandrel.”” slip op. at 10

    “That argument, however, does not explain why it would have been obvious to laterally offset the groove of Yoakim from the chamfered mandrel. Rather, as demonstrated by Mr. Jobin’s testimony, this argument relates to the general use of a sealing member in a groove, to the extent it was ultimately determined that such a configuration is not expressly disclosed in Yoakim. Id.; Ex. 1003 ¶ 296 (“It would have been obvious to one skilled in the art to position a sealing member in a groove to solidify the between counter-force portion 161 and engaging portion 157 in Figure 35 of Yoakim is more appropriately identified as the claimed “groove.” Prelim. Resp. 60–61. We need not resolve this issue, however, as Petitioner does not persuasively demonstrate that either potential “groove” is “laterally offset” from the chamfered mandrel. placement of the seal and improve its sealing stability and strength. Furthermore, it would have been obvious to one skilled in the art to utilize a groove and seal configuration in the brewing head . . . .”) (emphasis added). Even if we interpret the recited portion of the Petition as an argument for placing the groove entirely to the side of the mandrel in Yoakim, the Petition does not persuasively explain why one of ordinary skill in the art would have sought to do so. In Figure 35 of Yoakim, the seal and groove, as well as an elastic loading means, act as a valve means to control the level of pressure exerted in the capsule and “optimize interaction of water and the ground coffee particles to obtain a good extraction of the coffee and aroma compounds.” Ex. 1004 ¶¶ 370–372, 382, 396–398, 434–436, 445; Ex. 1003 ¶¶ 286–290; Pet. 63. These are the same beneficial properties relied upon by Petitioner to support the proposed combination, and Petitioner does not persuasively explain why one of ordinary skill in the art would have modified Yoakim in order to achieve results that are already obtained in the identified embodiment. Pet. 63. In view of the foregoing, we determine that Petitioner does not demonstrate a reasonable likelihood that claims 1 and 12 would have been obvious over the combined disclosures of Yoakim, Jarisch 929, and Rossi.” slip op. at 20

    “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.

    “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
