“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“Although the parties spend significant portions of their briefing discussing the term “eccentric” and how it applies to certain figures from the ʼ203 patent and the relied-upon prior art, we determine that it is not necessary to expressly construe the term “eccentric” beyond the parties’ agreed-upon definition.

“(opining that “Patent Owner’s construction of ‘having an axis no located in a geometric center’ is too narrow”). Mr. Nranian’s Declaration testimony in this respect is not persuasive for several reasons. First, it is internally inconsistent. Compare Ex. 1016 ¶ 3 (criticizing the “axis” language in Patent Owner’s definition), with id. ¶¶ 9, 11 (relying on that very language to support an argument). Also, Mr. Nranian’s proposed definition of “eccentric” to merely mean “not located at the center” begs the question of what, precisely, is “the center”? Mr. Nranian does not persuasively explain how far a person of ordinary skill in the art would understand she could travel from the exact center point of an object and still be in “the center” of that object. See Tr. 10:13–19 (Judge McGee asking whether the center is “a miniscule point in the middle of [the] disc”); see also id. at 10:25–12:26 (Judge Weatherly highlighting the significant ambiguity in referring to something as in “the center”). Also, Mr. Nranian’s opinion is inconsistent with how the ʼ203 patent compares something that is “central,” i.e., “at the center,” and something that is “eccentrically” located. Ex. 1001, 7:13–14 (describing pipe nozzle 15 as “central”); id. at 8:53–56 (describing a “through hole” as “located in the center of the front panel 22” depicted in Figures 7 and 8); id. at 10:23–31 (describing return 12 as “in the center” and outlet 13 as “eccentrically thereto” in Figure 17). Patent Owner’s colorized and annotated Figure 7 is reproduced below: Patent Owner’s colorized and annotated version of Figure 7 of the ʼ203 patent illustrates “central pipe nozzle 15” in yellow passing through the “through hole” located in “the center” of front panel 22. PO Resp. 20. Significantly, pipe nozzle 15 and the through hole in panel 22 are both described as “central” and in “the center” but must have different diameters; otherwise, “central pipe nozzle 15” would not be capable of traveling through “through hole 22.” Ex. 1001, Fig. 7. Thus, the ʼ203 patent intrinsically bases whether an element is “central” or “in the center” on whether its axis is located at the geometric center. This is also illustrated in Figure 17 of the ʼ203 patent, reproduced below: Figure 17 of the ʼ203 patent illustrates filter housing 10 with return 12 “in the center . . . and, eccentrically thereto, the outlet 13 with the seat 14 for the blocking element 24.” Ex. 1001, 10:23–30. Finally, Mr. Nranian’s narrow interpretation of “eccentric”––which excludes the “having the axis or support so located” in the geometric center language––is at odds with the arguments it was proffered to support. Cf. Pet. Reply 9 (arguing that certain elements are eccentric because they “do not have an axis located at the geometric center”); id. at 10 (arguing the eccentricity of an element that does “not have an axis in the center” which has “an off-center axis”).” slip op. at 29

Moreover, as Petitioner correctly points out, the ʼ087 patent expressly teaches that the precise conditions for forming a protective polymeric coating “will vary depending upon factors such as, without limitation, the nature of the monomer compound, the crosslinking agent, the substrate, as well as the desired properties of the coating” and that such “conditions can be determined using routine methods.” Ex. 1001 15:1–15:5 (emphasis added); Pet. Reply 17.

“We disagree with Patent Owner. Although the claims of the ʼ087 patent recite obtaining the protective cross-linked polymeric coating “by exposing the device or component to a plasma,” the field of endeavor analysis in an analogous art inquiry does not exclusively turn on the claims at issue, but rather takes account of the entirety of a patent’s disclosure. See In re Bigio, 381 F.3d 1320, 1326 (Fed. Cir. 2004) (explaining that “the PTO must show adequate support for its findings on the scope of the field of endeavor in the application’s written description and claims” (emphasis added)); In re Mettke, 570 F.3d 1356, 1359 (Fed. Cir. 2009) (rejecting an argument that the field of endeavor was limited to a claimed “Internet terminal” when “the specification describes various communication media, including facsimile machines and email, as related to the invention.”). This is significant here because the ʼ087 patent discloses that “[t]he … invention relates to protective coatings” and specifically “relates to protective coatings for electronic or electrical devices and components thereof, and methods of forming such coatings.” Ex. 1001, 1:14–17. Based on this disclosure, we find that the ʼ087 patent’s field of endeavor relates to “protective coatings for electronic or electrical devices and components thereof” broadly, not just those formed on such devices or components via a plasma polymerization process as asserted by Patent Owner. Id. Although Cohen does not explicitly disclose that its crosslinked polymers constitute a “protective coating,” Cohen does disclose that its “copolymerizable mixture can be cast into films” (Ex. 1004, 2:61–62), that the polymerization can “effected in situ,” and that the polymers may be used in “numerous” electrical applications (id. at 5:17–25). Tr. 8:9–10:2, 27:2– 21; see Pet. Reply 5 (explaining how “Cohen described insulating polymers that could be applied as films and be used to protect substrates including cables and electrical coils.” (citing Ex. 1004, 2:60–63, 5:13–25)). These disclosures suggest strongly that Cohen’s crosslinked polymers––if cast into a film or formed in situ on an electrical device or component––would serve as a protective coating on that electrical device or component, even though Cohen does not expressly refer to its crosslinked polymers ipsis verbis as a “protective coating.” Thus, we find that Cohen is within the field of endeavor of the ʼ087 patent.” slip op. at 15

“Pet. 5–6 (citing Ex. 1003 ¶ 50). Petitioner further states “that more education could compensate for less experience and vice versa.” Id. at 6. Petitioner’s position is, therefore, consistent with Patent Owner’s proffered level of skill in the art which reflects less education and more experience in substantially the same fields. Specifically, Patent Owner asserts that such a skilled artisan “would have at least a bachelor’s degree in mechanical or automotive engineering and/or five or more years of experience in the automotive industry designing, developing, testing, and engineering automotive components or practical experience servicing, assembling, repairing, and/or developing internal combustion engines and/or engine oil filters.” Prelim. Resp. 4. On this record, we determine that the level of ordinary skill is reflected in the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (specific findings on the ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985))). A more specific definition is not necessary for purposes of deciding whether to institute review. To the extent a more specific definition is required, however, we adopt Patent Owner’s definition because it is consistent with the disclosures of the asserted prior art references. We note, however, that we would reach the same conclusion under either parties’ definition.” slip op. at 7

“Petitioner asserts that all non-“means” terms in the challenged claims should be afforded their plain and ordinary meaning, and that the “means” limitations recited in claims 1 and 15 should not be construed as means-plus- function terms pursuant to 35 U.S.C. § 112(6). Pet. 7. According to Petitioner, claims 1 and 15 include additional limitations that denote structure for those “means” limitations and furthermore do not recite a function corresponding to the recited means. Id. Patent Owner asserts that “the Board need not make a determination on claim construction in assessing whether to institute” trial. Prelim. Resp. 5. After review of the preliminary record, we determine that no claim terms require an express construction for purposes of institution. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed.

“2. Advanced Bionics Prong One: whether “the same or substantially the same art or arguments previously were presented to the Office” As Petitioner acknowledges, a Japanese-language version of Yokoyama was cited in an IDS without an English translation. Pet. 19; Ex. 1002, 34 (indicating that an English translation was not provided by virtue of the absence of a checkmark in the “T” column on the far right of the PTO/SB/08a form).4 The Yokoyama reference relied on in the Petition (Ex. 1008) however, includes an English language translation of the text in 4 It is also not readily apparent that Patent Owner complied fully with the “Content Requirements for an Information Disclosure Statement” as set forth in MPEP § 609 in its IDS submission dated March 30, 2015. Specifically, § 609.04(a)(III) states that “[e]ach information disclosure statement must further include a concise explanation of the relevance . . . of the information listed that is not in the English language.” (italicized emphasis added, underlining in original); see also § 609.01 B.3 (stating this requirement). It does not appear that any concise explanation was filed with respect to either Japanese reference filed in the IDS. See Ex. 1002, 13–38 (IDS documents pertaining to Yokoyama reference); Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 1376 (Fed. Cir. 2000) (“[A]lthough MPEP Section 609[] allows the applicant some discretion in the manner in which it phrases its concise explanation, it nowhere authorizes the applicant to intentionally omit altogether key teachings of the reference.”). addition to the Drawings that also appear in the untranslated Japanese-language version of Yokoyama submitted during prosecution. Compare Ex. 1007 (containing Japanese text with Figures 1–7c), with Ex. 1008 (containing English text along with Figures 1–7c). As such, the Yokoyama reference relied on in the Petition––being in English––contains roughly ten pages of more readily discernible information than the Japanese-language version of this reference submitted during prosecution. Significantly, Petitioner relies on textual disclosure in the English-translated version of Yokoyama in its challenges. Pet. 28–51, 54, 58, 59 (citing Ex. 1008 repeatedly). Such English-translated disclosure was not previously before the Examiner. Ex. 1002, 13–38. In view of this additional disclosure before us in English, i.e., disclosure that was not presented previously to the Office, we find that the English translated version of Yokoyama relied on here (Ex. 1008) is not “the same or substantially the same art” that was previously presented to the Office (Ex. 1007).” slip op. at 10

“discretionary denial, we must also consider whether the Petition presents compelling merits. IPR2022-01242, Paper 23 at 4–5. As set forth above, we have considered the circumstances and facts before us in view of Fintiv factors 1–5, and determine that: Factor 1 is neutral, Factor 2 weighs heavily against discretionary denial, Factor 3 is neutral, Factor 4 weighs against discretionary denial, and Factor 5 weighs in favor of discretionary denial. Factors 1–5, considered as a whole, collectively weigh against exercising discretion to deny institution. As such, we need not undertake a “compelling merits” analysis as set forth under CommScope. The Merits Even though we do not consider here whether the merits are “compelling,” we do consider the merits of the Petition under Fintiv factor 6. As set forth below, we determine that Petitioner has satisfied the reasonable likelihood standard for purposes of institution. Such satisfaction weighs further against discretionary denial of the Petition.” slip op. at 19

“because they are premised on a misapplication of our precedent. Providing a document to the Office in an Information Disclosure Statement is sufficient to satisfy AB prong one as long as that “previously presented” art is “the same or substantially the same” as that presented in the Petition. See Advanced Bionics, 7–8 (holding that “[p]reviously presented art includes . . . art provided to the Office by an applicant, such as on an Information Disclosure Statement (IDS), in the prosecution history of the challenged patent”). As we have already found, there are no material differences between the asserted art and the prior art involved during examination under BD factor (a). Petitioner provides no authority that requires us to interpret “involved during examination” under BD factor (a) as “used in a rejection” or “mentioned by the examiner” (Pet. 60), and we are aware of none. Patent Owner’s position, in that regard, appears to conflate the first AB prong (whether the art previously was presented to the Office) with an aspect of the second AB prong (the extent to which the Examiner considered that art).” slip op. at 11
