    “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. 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.

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

    “c. Analysis We are not persuaded by Petitioner’s rationale for adding a facilitator- type webserver to the Ellis–Spivey combination based on “POSA’s Knowledge.” First, Petitioner’s combination of Spivey with Ellis is already allegedly based on improving latency issues via the incorporation of Spivey’s LDSD and MQSD in Ellis’s system. See Pet. 22–24. Petitioner touts that this modification would result in reduced latency to a time period “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. at 23 (citing Ex. 1017 ¶ 96). But the Petition does not establish whether this latency improvement would or could be maintained when adding a separate webserver, as it has proposed. And Dr. Rubin testifies that the inclusion of an additional webserver—an additional component—is likely to create latency insofar as it must receive, process, and/or handle data. Ex. 2001 ¶ 305. We are persuaded by Dr. Rubin’s testimony, and we find that adding a webserver to Petitioner’s existing Ellis– Spivey combination tends to undermine Petitioner’s foundational rationale for combining these references, which is the reduction of latency. See Pet. 23.” slip op. at 22

Dr. Wicker’s supporting testimony stresses that “webservers were well-known components in streaming systems that were useful for facilitating communication between client devices and socket servers, and client devices and media sources.” Ex. 1001 ¶¶ 128–132. But “obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v.

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.

    “These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum. The Petition does not explain why so many grounds are necessary under the circumstances or why the Board should impose on Patent Owner the burden of defending against so many challenges. See generally Pet. An inter partes review based on 24 distinct grounds raised against a single claim, supported by analysis lacking in particularity, potentially burdens Patent Owner unduly and makes inefficient use of the Board’s resources. See PTAB Consolidated Trial Practice Guide (Nov. 2019),22 56 (“The AIA was ‘designed to establish a more efficient and streamlined patent system that will improve patent quality and limit unnecessary and counterproductive litigation costs.’” (quoting H.R.

    “and Petitioner’s failure to persuasively explain why the particular proportion depicted in the ’151 patent is preferable to any other, Petitioner has not sufficiently shown that this proportion is primarily functional and should not be considered as part of the ornamental design. See, e.g., LA Gear, Inc. v. Thom McAn Shoe Co., 988 F.2d 1117, 1123 (Fed. Cir. 1993) (“When there are several ways to achieve the function of an article of manufacture, the design of the article is more likely to serve a primarily ornamental purpose.”). Moreover, we agree with Patent Owner that the differences in proportion between Neutrogena and the claimed design contribute significantly to the overall visual impression of the design. See Prelim. Resp. 28 (“[T]he two designs considered as a whole present dramatically different visual appearances.”), 33–36 (“To get from the Neutrogena jar design . . . to the design of the D ‘151 patent would require entirely changing the proportions of the jar—from a short neck with a tall base to a tall neck with a short base . . . .”). For example, Patent Owner creates an image showing that simply changing the height of the Neutrogena jar neck to have the same neck-height to base-height ratio as the ’151 patent without changing the other dimensions of the jar would yield a “ridiculous result.” Id. at 37. We agree that the two images, reproduced below, do not convey the same overall visual impression. This figure contains two images side by side. On the left is a side view drawing of the claimed jar. On the right is a front side image of the Neutrogena jar with the image manipulated to show a neck to base proportion equivalent to that of the claimed jar drawing. Prelim. Resp. 38. The images above show a figure from the ’151 patent, above left, and Patent Owner’s created image of Neutrogena, above right, with only the neck height modified to match the proportion of neck to base height shown in the ’151 patent. Although we do not necessarily agree with Patent Owner’s assertion that the created Neutrogena image represents the proposed combination asserted in the Petition, or that the modified image created by Patent Owner is accurate, we do agree with Patent Owner that the image of the modified Neutrogena jar illustrates that the proportion of neck height to base height contributes to ornamental aspects of the claimed jar and significantly affects the overall visual impression.” slip op. at 26

    “We find these aspects of the design significantly affect the overall visual impression of an otherwise simple design, particularly in an otherwise crowded art. Petitioner addresses these differences by stating that a designer of ordinary skill in the art “would have understood that different degrees of radius for the concave bottom surface would be a design choice for volume and accessibility to the contents, especially together with the radiused transition between the sidewall and bottom surface.” Pet. 56 (citing Fletcher Decl. ¶ 98). However, the present record does not support a finding that, even though other interior compartment shapes and depths are available, functionality dictates a certain shape and depth. Petitioner cites no other prior art that shows an interior compartment with a shape and depth equivalent to that shown in the ’151 patent. See Pet. 28–29 (showing annotated versions of Huang’s drawings, which do not clearly show the shape or depth of the interior compartment), 63 (proposing to modify Huang’s two chamber interior compartment with that of Canamasas Puigbo), 85–88 (showing the McKernan Jar drawings, which do not indicate the shape or depth of the interior compartment); Ex. 2002, 13 (explaining that the interior of Zamberlan is different in shape and depth than the claimed design). We are not persuaded to the contrary by Petitioner’s expert testimony. Mr. Fletcher testifies that Canamasas Puigbo “explicitly discloses a concave bottom surface in an article having more visually similar design, which would provide ample motivation to incorporate the feature.” Fletcher Decl. ¶ 98 (emphasis added). Thus, Mr. Fletcher appears to agree that the shape of the Canamasas Puigbo’s internal compartment is noticeably different than that of the ’151 patent. Mr. Fletcher does not address why a designer of ordinary skill in the art would have overlooked these differences or found them so minimal as to not affect the overall impression of the resulting modified jar. For example, Mr. Fletcher does not support this conclusion with any objective evidence, such as pointing to other prior art with an interior compartment the same shape and depth as that of the ’151 patent. Nor does Mr. Fletcher otherwise explain why a designer of ordinary skill in the art would have chosen to use the particular shape and depth claimed by the ’151 patent as opposed to all other possible configurations. See, id. ¶¶ 83–101. Moreover, as noted above, “expert testimony cannot take the place of disclosure from patents or printed publications.” 2019 Trial Practice Guide at 36. Accordingly, even after combining the visual features of Neutrogena and Canamasas Puigbo as proposed by Petitioner, the record evidence does not support Petitioner’s assertion that a designer of ordinary skill in the art would have found it obvious to modify Neutrogena such that its internal compartment is the same shape and depth as claimed by the ’151 patent.” slip op. at 32

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

    “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
