“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 Dobashi’s RSm values. 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.

“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)).

Patent Owner argues that “Petitioner fails to demonstrate that Ferman discloses ‘identifying . . . a plurality of first[/second] transitional clips.’” Prelim. Resp. 39 (alteration in original).

“III. CONCLUSION We have weighed the evidence presented by Petitioner and considered its arguments. We determine that Petitioner fails to establish a reasonable likelihood that it would prevail with respect to at least 1 of the claims challenged in the Petition. For each challenged claim in each asserted ground of unpatentability, Petitioner fails to establish that the asserted art teaches or suggests multiple recited limitations. Accordingly, we determine that trial should not be instituted on claims 1–20 of the ’185 patent. IV. ORDER Upon consideration of the record before us, it is: ORDERED that the Petition is denied as to all challenged claims, and no trial is instituted.” slip op. at 37

“review. 35 U.S.C. § 314; 37 C.F.R. § 42.4(a) (“The Board institutes the trial on behalf of the Director.”). The standard for institution is set forth in 35 U.S.C. § 314(a), which provides that inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” After considering the Petition and the Preliminary Response, as well as the evidence of record, we deny institution of inter partes review of the ’185 patent. 3 1 Petitioner identifies TikTok Inc., Bytedance Ltd., Bytedance Pte.

However, these papers were limited to arguments related to discretionary denial under 35 U.S.C. § 325(d).

- Skill levelSkill level petitioner adoptedDecided for petitioner
“B. Level of Ordinary Skill in the Art Petitioner contends: A person of ordinary skill in the art at the time of the ’185 patent (“POSITA”) had at least a Bachelor of Science in electrical engineering, computer engineering, or similar fields and at least two years of practical experience in the field of media processing and/or transmission. More education can supplement for less practical experience, and vice versa. Pet. 5. Patent Owner does not dispute Petitioner’s description. Prelim. Resp. 23. Determining the level of ordinary skill in the art involves various factors, 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 prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this Institution Decision, we adopt the description offered by Petitioner. It is not disputed by the Patent Owner and is consistent with the ’185 patent and the asserted prior art.” slip op. at 8

“C. Claim Construction In inter partes reviews, the Board construes claims using the same claim construction standard employed in a civil action under 35 U.S.C. § 282(b). 37 C.F.R. § 42.100(b). The “words of a claim ‘are generally given their ordinary and customary meaning,’” as would have been understood by a person of ordinary skill in the art at the time of the invention. Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.

“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.

“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
