      “B. The Fintiv Factors and Related Guidance The Board’s precedential decision in Fintiv outlines factors that balance considerations of system efficiency, fairness, and patent quality when a patent owner raises an argument for discretionary denial due to the advanced state of a parallel proceeding, such as the MDL proceeding here. Fintiv 5–6. These factors are: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits. Id. “[I]n evaluating the factors, the Board takes a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review.” Id. at 6.” slip op. at 10

      “raised by this overlap, but given the circumstances, it does not effectively mitigate them. First, the disputed issues for Petitioner’s ODP defense are the same or substantially similar to those for the obviousness grounds in the Petition, but the Sotera stipulation does not prevent Petitioner from litigating those issues before both the district court (as part of its ODP defense) and here in the event an IPR is instituted.19 Second, the MDL proceeding 19 ODP or nonstatutory double patenting is, as the name implies, not premised on any statute. See, e.g., Ostuka Pharm. Co., Ltd. v. Sandoz, Inc., 678 F.3d 1280, 1297 (Fed. Cir. 2012) (“Nonstatutory double patenting is a judicially created doctrine grounded in public policy.”). Accordingly, it is not a ground Petitioner reasonably could have raised in this IPR. See 35 U.S.C. § 311(b) (inter partes review may be requested “only on a ground that could be raised under section 102 or 103”). includes other biosimilar applicant defendants who are similarly motivated to try to invalidate the ’865 patent claims, but who are not subject to any Sotera stipulation. Even if we institute review on Petitioner’s grounds here, those other defendants remain free to litigate the same grounds in the consolidated MDL proceeding. For these reasons and given the particular circumstances of this case, Petitioner’s Sotera stipulation does not sufficiently mitigate the risks of duplicated efforts or inconsistent decisions by making this IPR a “true alternative” to resolution of these issues by the district court. See Motorola Solutions, Inc. v. Stellar, LLC, IPR2024-01205, Paper 19, 3–4 (PTAB Mar. 28, 2005) (determining on Director Review that a Sotera stipulation did not ensure IPR would be a “true alternative” because Petitioner’s invalidity arguments “include combinations of the prior art asserted in these proceedings with unpublished system prior art, which Petitioner’s stipulation is not likely to moot” and thus the same or similar issues would remain in the parallel proceeding); SAP America, Inc. v.

      “However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15

      “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.

      “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). 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)).

      “agree with Patent Owner that Petitioner has not sufficiently shown for institution that Bansal teaches or suggests arranging light sources “such that a higher intensity of light is emitted proximate the second edges compared to the intensity of light emitted not proximate the second edges,” as required by the challenged claims. Instead, Petitioner demonstrates how Bansal describes varying the density of light source distribution throughout the array to provide a higher density of light in the entire peripheral area of the array, which includes the areas proximal to both the first and second edges, as compared to the central area of the array. See Pet. 36–37; Ex. 1005 ¶ 25. In this regard, Petitioner relies on Bansal’s Figure 9b, asserting that it “shows one embodiment where more light sources are placed near the edges of the panel compared to the light sources in the center.” Pet. 36–37. The comparison of Bansal’s light density between the entire periphery and the central area of the array is insufficient. What is missing from Petitioner’s argument and discussion of Bansal is how Bansal teaches or suggests a configuration that provides a higher density of light proximate to the second shorter edges of the periphery in comparison to the remaining areas of the array, which includes the first longer edges of the periphery. Without that discussion, we find that Petitioner has not shown sufficient for institution that Bansal is persuasively relied upon for the light source arrangement limitation of the challenged claims. likelihood of prevailing in its obviousness challenge of independent claims 1, 5, 16, 20, or 21, or dependent claims 2, 4, 6–8, and 17–19 over Larsen, Bansal, and Jones.” slip op. at 17

Pet. 8. Petitioner asserts that, alternatively, a “POSITA in the relevant time frame would have had at least four years of industry or academic experience in optics, optoelectronics, radiometry, photometry, PD, PDT, PT, or a related field.” Id. (citing Ex. 1003 ¶ 37). According to Patent Owner, a person of ordinary skill in the art at the time the application for the ’028 patent was filed, “would have had a M.D. and/or a Ph.D. in an electrical engineering, physics, optical sciences, optical engineering, or a related scientific or engineering field, and at least one to two years of work or research experience in optical engineering, optics, optoelectronics, phototherapy (‘PT’), PDT, or a related field.” Prelim. Resp. 16. Patent Owner asserts that, “[a]lternatively, a POSITA could have a Bachelor’s degree in one of the above areas and at least three to four years of work or research experience in that area.” Id. (citing Ex. 2001 ¶¶ 30–31). We note that the parties’ proposed definitions are largely similar. To the extent that the proposed definitions differ, we do not need to resolve those differences as our findings and conclusion in this Decision would be the same under any of the proposed definitions.” slip op. at 9

      “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
