“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

“Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v.

“7. Balancing the Fintiv Factors As discussed above, factors 1 and 3–5 each favor denial. Factor 2 is the only factor that favors institution because there is no trial date in the Parallel Proceeding and the evidence presented of a median time-to-trial for civil trials in that district suggests a potential trial date after the statutory deadline for a final written decision in this proceeding. However, Patent Owner also shows that discovery and any dispositive motions will be completed in the Parallel Proceeding well before the statutory deadline for a final written decision in this proceeding, which presents a risk of duplicated efforts given the unmitigated overlap in issues between proceedings. On balance, considerations concerning an uncertain trial date in the Parallel Proceeding under Factor 2 do not outweigh the more substantial reasons identified under the other Fintiv Factors.

“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.

“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).

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.

“We agree with Patent Owner. Petitioner argues that “Patent Owner made the deliberate choice to claim broadly,” eschewing “structural limitations that would have expressly or implicitly required the hydraulic of Element [1.4] to differ from the hydraulic of Element [1.5].” Reply 7. Further, Petitioner argues that “Patent Owner chose to generically recite ‘a hydraulic’ in each of Elements [1.4] and [1.5] without distinguishing labels, identifiers, or qualifiers.” Id. To the contrary, the two recited “hydraulic[s]” are distinguished by the language surrounding and modifying each instance in the method of claim 1. Indeed, the recitations of distinct operations performed by each “hydraulic,” in the claimed method, further support the understanding these are distinct and different structures. Additionally, as Patent Owner contends (see Prelim.

“As Patent Owner argues, Petitioner’s proposed combination of Funk and Lewis “would interfere with the intended operation of the Funk control system to move the lift arms up and down in response to inter alia changes in the height signal.” Prelim. Resp. 20. This scenario is similar to that in Tec Air, 192 F.3d at 1356, which involved a claimed injection-molding technique that used screw-threaded adjustable plugs accessed from the inner, cavity-facing, side of the mold. The proposed combination included a prior art reference disclosing adjustment members accessed from the opposite, outer, side of the mold, and having a non-threaded smooth tip that extended through the mold and into the cavity. Id. at 1360. The Federal Circuit held that the prior art reference was properly determined to teach away from the claimed invention, because “no screw driver would be able to turn the smooth-headed screws from the cavity-side of the mold,” hence the proposed “combination would be inoperable for its intended purpose.” Id. Likewise, the proposed combination in the present matter teaches away from the subject matter of claim 1, because it would “immobilize [Funk’s] main arm,” and its associated hydraulic cylinder 18, “leaving just ‘one’ of Funk’s two adjustment mechanisms — blade tilt — available for grade control” (Pet. 10), thereby decreasing the system’s accuracy (see Ex. 2001 ¶¶ 113– 14) and negating the very technique that Funk relies upon to achieve its stated goal.

“Thus, based in part on the “relatively minimal proceedings” in the District Court, and the “[t]he possibility of significant simplification” for the District Court from our claim construction of the term “release logic,” we decline Patent Owner’s invitation to discretionarily deny the petition. Moreover, we need not address Patent Owner’s contentions concerning discretionary denial because, as discussed below, Petitioner has not established a reasonable likelihood of prevailing on the merits in demonstrating unpatentability of any challenged claim of the ’953 patent. See MillerKnoll, Inc. v. Aaron DeJule, IPR2023-01428, Paper 8, 10 (PTAB March 22, 2024).” slip op. at 20

“We now turn to the merits of Petitioner’s asserted Grounds of unpatentability. Analysis of Claims We focus our analysis on the term “release logic,” which appears in all the challenged claims. As we explained above, we determined that the term “release logic” along with its recited functions should be construed under Section 112 ¶ 6 to cover “corresponding structure, material, or acts described in the specification and equivalents thereof,” that perform the recited functions. Petitioner did not identify how the asserted prior art described those structures or their equivalents. Instead, as discussed above, Petitioner relied on Patent Owner’s preliminary construction in the District Court, which Patent Owner identified in wholly functional terms as a “specific sequence of actions.” Pet. 6 (citing Ex. 1010; Ex. 1002 ¶¶ 52–53); Prelim. CC Reply 1 (citing Ex. 1010, 5). Thus, Petitioner’s analysis fails to address how the prior art meets the limitations set forth in the claims as we have interpreted those claims. Accordingly, we find that Petitioner has failed to meet its burden to establish a reasonable likelihood that it would prevail with respect to at least one of the claims challenged in the petition. Thus we deny institution of an inter partes review. See Samsung Elecs. Am., Inc. v. Cobblestone Wireless, LLC, IPR2024-00319, Paper 16, slip op. 16–23 (PTAB Jun. 24, 2024) (holding that because Petitioner’s obviousness showing was based on an incorrect claim construction, Petitioner did not demonstrate a reasonable likelihood that a claim limitation was disclosed by, or would have been obvious over, the cited reference).” slip op. at 49

“be persuasive, we conclude that an ordinarily skilled artisan would not have understood “release logic” to refer to, or to have a definite meaning as the name for structure. Accordingly, we find that any presumption that the claims at issue do not invoke § 112, ¶ 6 is overcome, and we conclude that “release logic” introduces claim language that is properly interpreted under § 112, ¶ 6. Dr. Hull’s testimony in the District Court appears to address only the embodiment disclosed in Figures 9–11 of the ’953 patent. He did not opine on the other embodiments disclosed in the patent, such as the embodiment in Figures 22–24 disclosing electronic third-quadrant release-logic binding system 2204. However, his testimony that the words of the claim would not be understood by an ordinarily skilled artisan to have definite meaning as the name for structure remains persuasive.” slip op. at 48

“sophistication of the technology; and (5) educational level of active workers in the field.” Id. ¶ 30. Dr. Hull fails to state whether these factors were relied upon in forming his opinion, and if so, he also fails to state the underlying facts or data relating to these factors on which the opinion is based. There is no evidence to support why an “advanced degree” in mechanical engineering and five years of relevant experience is required. His opinion is supported only by his statement that he is “familiar with the technology at issue here and the state of the art at the time the application leading to the ’953 patent was filed.” Ex. 1002 ¶ 31. Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight. 37 C.F.R. § 42.65(a). Here, based on Dr. Hull’s extensive experience, we give his testimony some, but little, weight. Patent Owner states that “for purposes of this Preliminary Response only, VSD does not now dispute the definition of the POSITA as set forth by Dr. Hull.” Prelim. Resp. 7. We note that Patent Owner’s position is based on Dr. Hull’s full testimony, not the excerpt asserted by Petitioner. Accordingly, for purposes of this Decision, and based on the limited record before us, we determine, based on Dr. Hull’s testimony, the cited prior art, and Patent Owner’s qualified agreement with Dr. Hull’s testimony, that a person of ordinary skill in the relevant technology would have had an advanced degree in mechanical engineering or a related discipline and five years of experience in either ski binding design, manufacture, or testing; research concerning ski bindings and related equipment; or the development of standards concerning ski bindings or related equipment. This level of skill is approximate, and more experience would compensate for less formal education, and vice versa.” slip op. at 25

“However, each of these asserted modifications is based on a teaching that is not present in Brown. Brown does not teach “a projection that provides resistance against ‘handle’ movement” or that “opening Brown’s ‘cover’ requires bending Brown’s ‘port,’” as asserted by Petitioner. See PO Resp. 22. As repeatedly noted, the identified “projection” appears to be nothing more than a portion of cover 14 the accessory/hose port. Petitioner’s arguments regarding a projection that provides resistance and a bendable port in Brown, appear to be nothing more than an effort to create the limitations of the claims in the prior art based on improper hindsight. For at least the above reasons, the Petition does not show how Brown teaches or suggests all of the limitations of the independent claims.” slip op. at 13

“Petitioner argues that when cleaning tool 10 (i.e. accessory) is in position on the vacuum, end wall 26 cannot open and, thus, that end wall is inhibited from opening. Pet. 45–46 (citing Ex. 1005, ¶ 37, Fig. 2; Ex. 1002 ¶¶ 143–145 (similar statements from Petitioner’s declarant)). Petitioner then asserts that the catch is therefore inhibited from moving to the disengaged position. Id. at 46. The combination of Dimbylow and Howes does not teach this limitation and Petitioner’s assertions are not persuasive. As can be seen from the above annotated Figure, nothing inhibits Dimbylow’s catch 42 from moving to a disengaged position. See also Prelim. Resp 11–14. Rather, any time Howe’s button is pressed, thereby moving the push-rod (to the right in the Figure), catch 42 would disengage, whether the door opened or not. Though cleaning tool 10 (i.e. accessory) inhibits end wall 26 from opening, it has no impact on movement of catch 42 (i.e. lock engaging member) from the engaged to disengaged position as required by the claim. Thus, the lock engaging member of Petitioner’s combination, i.e., the catch, is not inhibited from moving to a disengaged position when the accessory, i.e., the cleaning” slip op. at 17

Additional education could offset less experience and vice versa, and a POSA could have also obtained similar knowledge and experience through other means. Ex. 1002 ¶ 42; see also Pet. 22 (making the same assertion without citation to declarant). Patent Owner does not contest the level of skill. Prelim. Resp. 2.

“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.

“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
