      “Petitioner also focuses on Hanafusa’s teaching that all known methods can be used to make a rough surface low-profile, and Dobashi’s teaching that RSm can be used as an indicator for judgment of the surface, to support its contention that a POSITA would have been motivated to apply Dobashi’s RSm to further achieve Hanafusa’s purpose, without explaining how and why that would be the case. In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve 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 and is rough when RSm is small.” Id. at 3:1–3, 6:27–29. Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66– 3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66–3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

    • Expert testimonyPetitioner expert discountedDecided for patent owner

      “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. 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). to little weight. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v.

Mova Pharm. Corp., 225 F.3d 1306, 1311 (Fed. Cir. 2000) (“Lack of factual support for expert opinion to factual determinations, however, may render the testimony of little probative value in a validity determination.” (quoting Ashland Oil, Inc. v. Delta Resins and Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985))); see also In re Ethicon, Inc., 844 F.3d 1344, 1348, 1352 (Fed. Cir. 2017) (concluding that the Board properly gave “little weight” to conclusory expert testimony of objective indicia). Because Petitioner offers Dr. Randall’s testimony to supply a limitation missing from the prior art, namely, the CTE measurement method, and we give Dr. Randall’s unsupported and conclusory testimony little weight, we are not persuaded that Petitioner establishes a reasonable likelihood of showing that Khatibi discloses limitation [1d].” slip op. at 17

      “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)). Thus, we are not persuaded, on this record, that the combined disclosures of Kim and Griesi teach all of the elements of limitation [1g].” slip op. at 23

      “However, Petitioner does not sufficiently explain where Rao teaches “allow[ing] or disallow[ing]” as recited in claim 1. See Pet. 13–18, 25–30. To the extent Petitioner and Dr. Bims cite to Rao, they reference paragraphs 191 through 193, which discuss how Rao’s filter 322 is used to implement prioritization. See Pet. 15; Ex. 1003 ¶ 65. More specifically, those paragraphs recite using prioritization to place the network packets in different queues based on their priority. See Ex. 1005 ¶¶ 191–193. We see nothing in Rao that teaches or suggest that the network packets would be disallowed, as opposed to simply delayed, based on priority. Id. And, as Patent Owner argues, this finding is consistent with factual findings made by a different panel considering the teachings of Rao in an inter partes review of a related patent. See Prelim. Resp. 16–18 (citing Samsung Elecs. Co v. Headwater Research LLC, IPR2023-01361, Paper 8 (PTAB Mar. 29, 2024) (Decision Denying Institution)). Even if one reads the Petition as arguing that a person having ordinary skill would have modified Rao to include Araujo’s blocking—which we do not—we would not be sufficiently persuaded by that argument. Although Petitioner explains why a person having ordinary skill in the art would want to consider power usage along with whether the application is in the foreground or background, Petitioner does not explain why a person having ordinary skill in the art would have changed prioritization to blocking. See Pet. 13–18. Indeed, such a modification appears to be one that would render Rao “inoperable for its intended purpose.” In re Gordon, 733 F.2d 900, 902 (Fed. Cir. 1984).” slip op. at 18

      “Neither the Petition nor Dr. Wolfe’s testimony provide any discussion as to why a person having ordinary skill in the art would have modified Rao to teach the additional limitation recited in either claim 79 or 83. See Pet. 22–23; Ex. 1015 ¶¶ 252–257. This stands in contrast to other portions of the Petition where Petitioner clearly set forth both anticipation and conditional obviousness arguments, including a reason to modify Rao. See, e.g., Pet. 13–15 (arguing that Rao discloses limitation 1e or that a person having ordinary skill in the art “would . . . have been motivated” to modify Rao). Thus, although the Petition purports to argue that claims 79 and 83 are obvious,8 the Petition lacks sufficient argument setting forth the basis for such an obviousness argument. At most, there is a conclusory statement that claims 79 and 83 are obvious. See Pet. 6 (“Rao anticipates most of the limitations discussed under this Ground for the reasons provided below. Rao renders these same limitations obvious for the same reasons.”). That is not sufficient. Where, as here, claims are alleged to be unpatentable as obvious over the prior art, Petitioner cannot make its case solely through mere conclusory statements.

      “large number of claims alone is not sufficient to justify the filing of the second set of petitions when the first set already covers all 152 claims of the ʼ260 patent. We therefore turn to Petitioner’s reasons for why it filed the second set of petitions.

      “the prior art was utilized in related proceedings supports instituting three petitions other than the fact that three petitions rely on different prior art that has been used in prior petitions to different effect. As Patent Owner points out, however, “[n]early all parallel petitions involve different proposed prior art” (Prelim. Resp. 7) and, in this case, the differences in whether that prior art was the subject of prior proceedings are not sufficient to justify filing two additional petitions.” slip op. at 15

    The Board denied institution of review of claims 1–7 and 9 under § 314(a), finding no justification for this second parallel petition challenging the same claims.

    RulingsInstitution decision
    • Parallel petitionsInstitution denied discretionary otherDenied

      “Based on the Board’s experience, one petition should be sufficient to challenge the claims of a patent in most situations. . . . . In addition, multiple petitions by a petitioner are not necessary in the vast majority of cases. To date, a substantial majority of patents have been challenged with a single petition. Practice Guide 59 (emphasis added). The Practice Guide provides examples of “circumstances in which more than one petition may be necessary.” Id. None of these examples are pertinent here. For example, a second petition might be justified “when the patent owner has asserted a large number of claims in litigation or when there is a dispute about priority date requiring arguments under multiple prior art references.” Petitioner does not argue that the number of claims in the parallel litigation is “large.” And while Petitioner does argue that the prior art relied upon on might be antedated, Patent Owner responds by stipulating “that it will not ‘attempt to antedate or disqualify’ the prior art relied upon by Petitioner.” Prelim. Resp. 6–7.” slip op. at 11

      “III. CONCLUSION For the foregoing reasons, we are not persuaded that the facts presented by Petitioner justify a second petition challenging the same claims of the ’307 patent as the petition in IPR2024-00413. We therefore exercise our discretion under 35 U.S.C. § 314(a) to deny institution of inter partes review. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 314(a), the Petition is denied and inter partes review of claims 1– 7 and 9 of the ’307 patent is not instituted on the grounds asserted in the instant Petition.” slip op. at 12

    The Board denied institution because Honeywell did not show a reasonable likelihood that claims 1–9 were unpatentable over any of its three obviousness combinations.

      “PHOSITA) at the time of the ’532 patent “would have had at least a Bachelor’s degree in the field of chemistry, chemical engineering, polymer chemistry, or materials science and at least three years of relevant work experience in the field of high strength fibers.” Pet. 8 (citing Ex. 1003 ¶ 18). 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. Prelim. Resp. 33–34. We note that the parties’ proposed definitions are largely similar, except that Patent Owner additionally recognizes a Bachelor’s degree in biomedical engineering and requires experience in designing and manufacturing gel-spun UHMWPE yarns. In any event, we do not need to the same under either proposed definition.” slip op. at 6

      “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. Cir. 2005); SciMed Life Sys., Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 1343–44 (Fed. Cir.” slip op. at 8

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITADecided for patent owner

      “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
