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)).

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.

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.

    “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.

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.

    “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.

    “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).

    “In each of the ’335 Specification, Stafford, Raymond, and Turner, the OBU is universally depicted as having a circular perimeter oriented around a longitudinal axis, and possessing either a cylindrical shape (’335 patent, Stafford, Raymond) or a roughly domed shape, with a circular, circumferential collar.

Given the circular perimeter of all of these embodiments of the disclosures of the ’335 Specification, the teachings of Petitioner’s cited references, the dictionary definition of “periphery” as being “the perimeter of a circle or other closed curve,” and the ordinary meaning that the terms would have had to a skilled artisan at the time of the invention, in view of the ’335 Specification and file history” (Phillips, 415 F.3d at 1312–13), we conclude that a person of ordinary skill in the art would understand that the “plurality of recesses disposed on a periphery of the on body electronics unit housing” would be located “on the circumference of the on-body housing,” as we concluded in the ’01396 IPR Decision.

    “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.

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.

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.
