Jun. 22, 2021) Copy Citation Trials@uspto.gov Paper 22 571-272-7822 Date: June 22, 2021 UNITED STATES PATENT AND TRADEMARK OFFICE BEFORE THE PATENT TRIAL AND APPEAL BOARD ALBANY INTERNATIONAL CORP., Petitioner, v. KIMBERLY-CLARK WORLDWIDE, INC., Patent Owner. PGR2021-00019 Patent 10,584,444 B2 Before CHRISTOPHER L. CRUMBLEY, SUSAN L. C. MITCHELL, and ELIZABETH M. ROESEL, Administrative Patent Judges. ROESEL, Administrative Patent Judge. DECISION Denying Institution of Post-Grant Review 35 U.S.C. § 324 PGR2021-00019 Patent 10,584,444 B2 2 I. INTRODUCTION A. Background and Summary Albany International Corp. (“Petitioner”) filed a Petition (Paper 14, “Pet.”) seeking a post-grant review of claims 1–13 (“the challenged claims”) of U.S. Patent No. 10,584,444 B2 (Ex. 1001, “the ’444 Patent”). Kimberly- Clark Worldwide, Inc. (“Patent Owner”) filed a Preliminary Response. Paper 18 (“Prelim. Resp.”). With the Board’s prior authorization (Paper 19), Petitioner filed a Reply to the Preliminary Response (Paper 20, “Pet. Reply”) and Patent Owner filed a Sur-reply (Paper 21, “PO Sur-reply”), limited to addressing Patent Owner’s arguments for discretionary denial of institution. Exercising the authority delegated to the Board under 35 U.S.C. § 324 and 37 C.F.R. § 42.4(a), we may not institute a post-grant review unless “the information presented in the petition . . . , if such information is not rebutted, would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a) (2018). In determining whether to institute a post-grant review, we “may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.” 35 U.S.C. § 325(d). After considering the information presented in the Petition and the Preliminary Response, we determine that the Petition does not meet the “more likely than not” standard with respect to any of the challenged claims. After considering the parties’ arguments concerning discretionary denial of institution, we determine that we should also exercise our discretion under § 325(d) to deny the Petition, which provides an additional reason for denying institution. Therefore, we deny institution of a post-grant review. PGR2021-00019 Patent 10,584,444 B2 3 B. Related Matters Aside from a pending continuation application, neither party identifies any judicial or administrative matter that would affect, or be affected by, a decision in the proceeding. Pet. 2; Paper 16, 1 (Patent Owner’s Mandatory Notices). C. The ’444 Patent (Ex. 1001) The ’444 Patent discloses a two layer papermaking belt useful in the manufacture of through-air dried tissue products. Ex. 1001, code (57), 1:59–64. The belt has a first woven layer and a second nonwoven layer joined together in a laminated arrangement. Id. The woven layer forms the machine contacting layer of the belt and is woven from a highly abrasion resistant material, while the nonwoven layer contacts the nascent tissue web. Id. at 1:64–2:8. There are voids between the first and second layers as a result of the woven layer having a three dimensional topography defined by yarns woven into ridges and valleys on top of which lies the nonwoven layer. Id. PGR2021-00019 Patent 10,584,444 B2 4 Figures 1A–1C of the ’444 Patent are reproduced below. Figures 1A–1C show a woven fabric that forms a support structure for a laminated papermaking belt. Ex. 1001, 3:11–16, 6:49–50. As shown in Figures 1B and 1C, the yarns are woven so as to provide two surface planes lying in different elevations--a first surface plane 51 having a first z-direction elevation and a second surface plane 52 having a second z-direction elevation. Id. at 6:63–67. As shown in Figure 1B, support structure 40 comprises a plurality of ridges 47 and valleys 49 aligned in the machine direction and spaced apart from one another in the cross-machine direction. Id. at 7:11–20. The upper surface of ridge 47 defines first surface plane 51. Id. at 7:5–6. PGR2021-00019 Patent 10,584,444 B2 5 Figures 5A and 5B of the ’444 Patent are reproduced below. Figures 5A and 5B show a laminated papermaking belt comprising nonwoven layer 200 laminated to support structure 300 formed from woven yarns 310, 312. Ex. 1001, 3:23–26, 12:37–41. As shown in Figure 5A, nonwoven layer 200 comprises lattice grid framework 210 having planar upper surface 202 and a plurality of rectangular shaped apertures 220 separated from one another by lattice grid elements 260. Id. at 11:9–11, 12:41–45. Apertures 220 open onto underlying support structure 300 to define web contacting portions 302, which together with upper surface 202 PGR2021-00019 Patent 10,584,444 B2 6 of framework 210 form the web contacting surface of the laminated belt. Id. at 12:45–49. As shown in Figure 5B, woven fabric 300 comprises yarns that are woven to provide two surface planes lying in different elevations--first surface plane 320 having a first z-direction elevation and second surface plane 322 having a second z-direction elevation. Ex. 1001, 12:50–55. Woven fabric 300 comprises a plurality of ridges 303, the uppermost portion of which define first plane 320, and a plurality of valleys 305 disposed between ridges 303, the upper surface of which defines second plane 322. Id. at 12:55–60. When nonwoven layer 200 and woven layer 300 are laminated to form the multilayer belt, a portion of nonwoven framework 210 bridges adjacent ridges 303 creating void 307 having a height (D) corresponding to the z-direction difference between first surface plane 320 and second surface plane 322 of woven layer 300. Id. at 12:65–13:6, 13:23–27. According to the ’444 Patent, it is preferred that yarns forming woven layer 300 are not enveloped or otherwise surrounded by nonwoven layer 200 after lamination and that bottom surface plane 214 of nonwoven layer 200 does not extend beyond uppermost surface plane 320 of woven layer 300, such that a distinct boundary is formed between nonwoven layer 200 and woven layer 300, which is generally coplanar with upper surface plane 320 of woven layer 300. Ex. 1001, 13:10–22. D. Illustrative Claim The ’444 Patent includes thirteen claims, all of which are challenged in the Petition. Claim 1 is the sole independent claim and is reproduced below with paragraph breaks added to make the claim easier to read. PGR2021-00019 Patent 10,584,444 B2 7 1. A laminated papermaking belt having a machine direction and a cross-machine direction, a machine contacting surface and an opposite web contacting surface, the belt comprising discrete first and second layers joined together in a face-to-face relationship, each of the at least first and second layers having a top surface, a bottom surface opposite to the top surface, the top surface of the first layer forming a portion of the web contacting surface of the belt, and the bottom surface of the second layer forming the machine contacting surface of the belt, wherein the first layer comprises a nonwoven material and the second layer comprises a plurality of woven ridges lying in a first x-y plane and a plurality of woven valleys lying in a second x-y plane below the first x-y plane such that the first layer contacts at least a portion of the plurality of woven ridges and comprises a plurality of suspended portions elevated in the z-direction from the second x-y plane to form void spaces between the second x-y plane and the suspended portions. Ex. 1001, 17:58–18:18. PGR2021-00019 Patent 10,584,444 B2 8 E. Asserted Grounds Petitioner asserts the following grounds of unpatentability: Claim(s) Challenged 35 U.S.C. § 1 Basis/Reference(s) 1 1–4, 6, 7, 9, 11–13 102(a)(1) Alleged sales of forming fabrics2 2 5, 8 103 Alleged sales in view of Eagles3 3 10 103 Alleged sales in view of Stone4 4 1–9, 11, 12 102(a)(1) Eagles 5 10 103 Eagles, Stone 6 13 103 Eagles in view of alleged sales 7 1, 2, 4, 5, 8, 9, 11, 13 102(a)(1) Sealey5 8 3, 6, 7, 12 103 Sealey, Eagles 9 10 103 Sealey, Stone 10 1–4, 8, 9, 11, 12 102(a)(1) JP ’2386 11 1–4, 8, 9, 11, 12 102(a)(1) Lefkowitz7 1 The Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112-29, 125 Stat. 284, 287–88 (2011), amended 35 U.S.C. § 103, effective March 16, 2013. The earliest possible effective filing date for the challenged claims is July 31, 2017. Ex. 1001, code (60). Because this date is after March 16, 2013, the AIA version of the statute applies, and the ’444 Patent is eligible for post-grant review. 2 Petitioner alleges that it sold MS015 forming fabric to Georgia-Pacific, LLC (“GP”) in December 2013 and that it sold LB003 and LB004 forming fabrics to GP in March 2015. Pet. 12–14. PGR2021-00019 Patent 10,584,444 B2 9 II. ANALYSIS A. Principles of Law In addition to patents and printed publications, the prior art for purposes of a post-grant review includes products that were “on sale . . . before the effective filing date of the claimed invention.” 35 U.S.C. § 102(a)(1); 35 U.S.C. § 282(b)(2), (3); 35 U.S.C. § 321(b). “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros. Inc., v. Union Oil Co., 814 F.2d 628, 631 (Fed. Cir. 1987). “[A] prior art reference may anticipate without disclosing a feature of the claimed invention if that missing characteristic is necessarily present, or inherent, in the single anticipating reference.” Schering Corp. v. Geneva Pharm., Inc., 339 F.3d 1373, 1377 (Fed. Cir. 2003). In AIA contested proceedings, “the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (addressing inter partes review); 35 U.S.C. § 322(a)(3) (requiring a post-grant review petition to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”); see also 37 C.F.R. § 42.204(b) (requiring a petition for post-grant review to identify 3 Ex. 1017, Eagles et al., US 2016/0090692 A1, published Mar. 31, 2016 (“Eagles”). 4 Ex. 1020, Stone et al., US 7,682,995 B2, issued Mar. 23, 2010 (“Stone”). 5 Ex. 1024, Sealey et al., US 2017/0233946 A1, issued Aug. 17, 2017 (“Sealey”). 6 Ex. 1025, JP 2008045238, published Feb. 28, 2008 (“JP ’238”). 7 Ex. 1026, Lefkowitz, US 5,077,116, issued Dec. 31, 1991 (“Lefkowitz”). PGR2021-00019 Patent 10,584,444 B2 10 how the challenged claim is to be construed and where each element of the claim is found in the prior art patents or printed publications relied upon). A patent claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved based on underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and, when presented, (4) objective evidence of nonobviousness, i.e., secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016). In determining whether to institute a post-grant review, we “may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.” 35 U.S.C. § 325(d). PGR2021-00019 Patent 10,584,444 B2 11 The Board’s most recent precedential decision addressing § 325(d) provides the following two-part framework: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims. Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6 at 8 (PTAB Feb. 13, 2020) (precedential). Advanced Bionics explains that the Becton, Dickinson factors8 provide “useful insight” into how to apply the statutory framework and address “challenging factual questions, such as when a ground of unpatentability presents ‘substantially the same prior art or arguments’ previously presented to the Office.” Id. at 9. B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art would have had at least a Bachelor’s degree with at least 2–3 years of experience 8 Becton, Dickinson identifies the following non-exclusive factors: (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which petitioner relies on the prior art; (e) whether petitioner has pointed out sufficiently how the examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the petition warrant reconsideration of the prior art or arguments. Becton, Dickinson and Co. v. B. Braun Melsungen AG, IPR2017-01586, Paper 8 at 17–18 (PTAB Dec. 15, 2017) (precedential as to § III.C.5, first paragraph). PGR2021-00019 Patent 10,584,444 B2 12 working in the papermaking textile arts, or a Master’s Degree or Ph.D. in engineering with an academic focus on textile belts used in papermaking or the papermaking arts. Pet. 10. According to Petitioner, a person of ordinary skill in the art would be familiar with fabrics, such as belts used in the papermaking process or textile industry. Id. We apply Petitioner’s definition of a person of ordinary skill in the art, which is undisputed by Patent Owner and consistent with the subject matter of the ’444 Patent and the asserted prior art. C. Claim Construction In a post-grant review, we apply the same claim construction standard as would be used by a district court to construe a claim in a civil action involving the validity or infringement of a patent. 37 C.F.R. § 42.100(b) (2020). Under that standard, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record. Id.; Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc); Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365–66 (Fed. Cir. 2012). For purposes of this proceeding, the parties do not dispute the meaning of any claim term. See Pet. 10–11 (relying upon express definitions in the ’444 Patent and providing express constructions for two terms in dependent claims); Prelim. Resp. 12 (asserting that issues raised in the preliminary response are not affected by claim construction). We agree with the parties that we do not need to resolve any claim construction disputes for purposes of this Decision. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be PGR2021-00019 Patent 10,584,444 B2 13 construed that are in controversy, and only to the extent necessary to resolve the controversy.”); see also Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (applying Vivid Techs. in the context of inter partes review). D. Lefkowitz Anticipation 1. Merits Petitioner contends that Lefkowitz “discloses a two-layer forming fabric, e.g., a belt for papermaking, that has a non-woven layer adhered to a woven layer.” Pet. 90 (citing Ex. 1026, Abstract). Petitioner contends that “[t]he woven layer has nonplanar ridges and valleys, each in a first and second x-y plane.” Pet. 91 (citing Ex. 1026, 4:62–6:7, Figs. 5–15). Petitioner contends that “[t]he nonwoven layer suspends over the valley portions of the woven layer” and that “[v]oids are created by the ridge and valley structure between the nonwoven and woven layers.” Id. (citing Ex. 1026, 5:54–58, 6:61–70, 8:53–70, Figs. 4–15). Petitioner provides the following annotation of Lefkowitz Figure 6. Lefkowitz Figure 6 is a cross-sectional view of a forming fabric having nonwoven sheet contact layer 34 comprised of randomly disposed continuous filaments 36 adhered to a woven base fabric having warp yarns PGR2021-00019 Patent 10,584,444 B2 14 and filling yarns. Ex. 1026, 4:35–36, 4:39–40, 4:62–68, 6:8–21; see also id. at 10:9–39 (claim 1). In Petitioner’s annotation, Petitioner contends that a blue arrow points to a “void created between the nonwoven layer and the woven layer.” Pet. 91. Petitioner contends that Lefkowitz’s “Figures 14 and 15 show how the nonwoven layer can suspend over the woven valleys.” Id. Patent Owner argues that Petitioner does not show where Lefkowitz teaches a “plurality of woven ridges” or a “plurality of woven valleys,” as recited in claim 1, and does not identify the two “x-y plane[s]” recited in the claim. Prelim. Resp. 35–39, 46. Patent Owner argues that “Lefkowitz is substantially monoplanar” and that Petitioner’s alleged void “is just an ordinary gap between yarns and common to any weave pattern.” Id. at 46 (Patent Owner’s annotation of Lefkowitz Figure 6 identifying essentially coplanar first and second surfaces). Patent Owner argues that Lefkowitz does not disclose woven valleys, a second x-y plane, void spaces, or suspended portions, as recited in claim 1. Id. at 47. We agree with Patent Owner that Petitioner’s contentions regarding Lefkowitz and claim 1 are deficient. Petitioner does not identify where the claimed ridges, valleys, and planes are disclosed in Lefkowitz. Pet. 90–93; Prelim. Resp. 35–39, 46. Although Petitioner asserts that, in Lefkowitz, “[t]he woven layer has nonplanar ridges and valleys, each in a first and second x-y plane” (Pet. 91), Petitioner does not specify where such ridges, valleys, and x-y planes are disclosed. Instead, Petitioner provides a citation to a lengthy portion of Lefkowitz’s written description and eleven of its fifteen drawings without appropriate elaboration as to how the description and drawings meet the claimed ridges, valleys, and planes. Id. (citing Ex. 1026, 4:62–6:7, Figs. 5–15). For instance, Petitioner provides a single annotation of a single drawing of Lefkowitz, identifying with a blue arrow PGR2021-00019 Patent 10,584,444 B2 15 an alleged “void” between the nonwoven layer and the woven layer. Pet. 91–92. But Petitioner does not provide annotations or other contentions sufficient to identify ridges, valleys, or x-y planes in Lefkowitz’s forming fabric. See 35 U.S.C. § 322(a)(3) (a post-grant review petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”); see also 37 C.F.R. § 42.204(b)(5) (a post-grant review petition must identify “the relevance of the evidence to the challenge raised, including identifying specific portions of the evidence that support the challenge”). The deficiencies in Petitioner’s contentions for independent claim 1, as discussed above, are not remedied by its contentions for dependent claims 2–4, 8, 9, 11, and 12. Pet. 93–98. For these reasons, we determine that Petitioner has not shown it is more likely than not that Lefkowitz anticipates claims 1–4, 8, 9, 11, and 12. 2. Section 325(d) Applying the Advanced Bionics two-part framework, we determine that Lefkowitz is the same as the art previously considered by the Office during examination. See Prelim. Resp. 21–22, 33–34 (Patent Owner’s § 325(d) argument concerning Lefkowitz). The Examiner rejected application claim 17 as anticipated by Lefkowitz. Ex. 1002, 53.9 In response, applicant argued that “Lefkowitz discloses a woven layer that is substantially monoplanar” and does not disclose a woven layer having a plurality of woven ridges lying in a first x-y plane and a plurality of woven 9 Claim 17–26 and 34–36 of application no. 16/317,671 correspond to claims 1–13 of the ’444 Patent. Ex. 1001, code (21); Ex. 1002, 18 (claim correspondence). PGR2021-00019 Patent 10,584,444 B2 16 valleys lying in a second x-y plane below the first x-y plane. Id. at 40–41. In addition, applicant argued that Lefkowitz does not disclose that the nonwoven layer has suspended portions lying above a woven valley. Id. at 41 (reproducing Lefkowitz Figures 14 and 15). Following this response, the Examiner allowed application claims 17–26 and 34–36 (corresponding to claims 1–13 of the ’444 Patent). See id. at 13 (Examiner’s indication of allowable subject matter). Under the second part of the Advanced Bionics framework, we determine that Petitioner has not demonstrated persuasively that the Office erred in its evaluation of Lefkowitz in a manner material to the patentability of the challenged claims. The Petition includes no substantive discussion of the prosecution history and does not address whether the Examiner erred in evaluating Lefkowitz. For the first time in the Reply, Petitioner argues that the Examiner and Patent Owner do not appear to have considered Lefkowitz’s teaching that its woven layer weave “prevents the yarns from forming a flat surface” and that the cross-machine direction yarns “do not reside in a single plane.” Pet. Reply 4 (quoting Ex. 1026, 5:12–17; emphasis is Petitioner’s). We agree with Patent Owner that the Petition does not direct us to this disclosure in Lefkowitz, which is contained within 82 lines of text cited by Petitioner. PO Sur-reply 2; Pet. 91 (citing Ex. 1026, 4:62–6:7, Figs. 5–15). We also agree with Patent Owner that Lefkowitz’s disclosure quoted in Petitioner’s Reply is a description of Lefkowitz Figures 2 and 3, which are no more pertinent in providing any teaching as to the limitations of claim 1 than Lefkowitz Figures 14 and 15, which were substantively addressed during prosecution. PO Sur-reply 2; Ex. 1002, 53 (Examiner’s rejection citing Lefkowitz Figure 15 as showing ridges, valleys, planes, suspended PGR2021-00019 Patent 10,584,444 B2 17 portions, and void spaces); id. at 40–41 (applicant’s response reproducing Lefkowitz Figures 14 and 15 and arguing that they do not show suspended portions lying above a woven valley). The prosecution history does not support Petitioner’s assertion that the Examiner did not consider Lefkowitz’s teaching about the woven layer’s yarns not forming a flat surface and not residing in a single plane. The same teaching is provided in Lefkowitz Figures 14 and 15, which were expressly considered by the Examiner. Ex. 1002, 13, 36, 41 (notice of allowability in response to applicant’s amendment and remarks discussing Lefkowitz Figures 14 and 15). Next, Petitioner argues that the Examiner does not appear to have considered Lefkowitz’s teaching that “a coating of particles that bridge across interstices between support surfaces in the base fabric.” Pet. Reply 4 (quoting Ex. 1026, 8:55–57; emphasis is Petitioner’s). We agree with Patent Owner that the cited disclosure of Lefkowitz does not show Examiner error. Pet Sur-reply 3. The cited disclosure is no more pertinent in providing any teaching as to the limitations of claim 1 than Lefkowitz Figures 6, 9, 12, and 15, which show a nonwoven layer adhered to a woven base fabric, with fibers of the nonwoven layer bridging interstices between adjacent yarns of the woven base fabric. As discussed above, the Examiner expressly considered and allowed the claims over Lefkowitz Figures 14 and 15. Ex. 1002, 13, 36, 41, 53. Petitioner does not persuade us that the Examiner erred by allowing the claims after considering applicant’s argument distinguishing Lefkowitz. PGR2021-00019 Patent 10,584,444 B2 18 E. Sealey Anticipation 1. Merits Petitioner contends that Sealey discloses a papermaking belt having a nonwoven top layer laminated to a woven bottom layer. Pet. 70 (citing Ex. 1024, Abstract, ¶¶ 27, 136, 139). Petitioner contends that “[t]he weaving pattern of the woven layer would be understood as having ridges and valleys” and that “[t]he ridges are in a first x-y plane and the valleys are in a second x-y plane.” Pet. 72 (citing Ex. 1024 ¶¶ 138, 139, Figs. 8, 11). Petitioner contends that “[a] void is created between the valleys of the bottom woven layer and the top nonwoven layer.” Pet. 73 (citing Ex. 1024 ¶ 34, Fig. 11). Petitioner relies on Sealey’s disclosure that the nonwoven and woven layers “have non-planar, irregularly shaped surfaces that when laminated together only bond together where the two layers come into direct contact” and that “the partial and uneven bonding between the two layers results in formation of air channels 320 that extend in the X-Y plane of the fabric or belt 300.” Id. (quoting Ex. 1024 ¶ 139). Petitioner contends that “[a] person of ordinary skill in the art would appreciate that the air channels are voids.” Id. (citing Ex. 1024, Fig. 8). PGR2021-00019 Patent 10,584,444 B2 19 Petitioner provides the following annotation of Sealey Figure 8. Sealey Figure 8 is a photo showing air channels formed in the fabric or belt described in Sealey. Ex. 1024 ¶¶ 125, 139. In Petitioner’s annotation, Petitioner contends that a blue arrow identifies “an elevated suspension of the nonwoven layer that extends between the ridges (and over the valleys) of the woven layer.” Pet. 74. Patent Owner argues that Petitioner does not show where Sealey teaches a “plurality of woven ridges” or a “plurality of woven valleys,” as recited in claim 1, and does not identify the two “x-y plane[s]” recited in the claim. Prelim. Resp. 35–40, 47. Patent Owner argues that Sealey describes a substantially monoplanar woven layer. Id. at 45, 48 (Patent Owner’s annotation of Sealey Figures 8, 11 identifying essentially coplanar first and second surfaces). Patent Owner argues that the air channel shown in Sealey Figures 8 and 11 is “below any second x-y plane defined by a woven valleys” and “results from the ordinary spacing between yarns that would be present in any weave.” Id. at 47, 48. Relying on Sealey’s disclosure that the PGR2021-00019 Patent 10,584,444 B2 20 nonwoven layer extends “partially through” the woven layer, Patent Owner argues that Sealey does not disclose the claimed void spaces or suspended portions. Id. at 48–49 (citing Ex. 1024 ¶ 136, Fig. 8). We agree with Patent Owner that Petitioner’s contentions regarding Sealey and claim 1 are deficient. Petitioner does not identify where the claimed ridges, valleys, and planes are disclosed in Sealey. Pet. 70–75; Prelim. Resp. 35–39, 47. Although Petitioner asserts that, in Sealey, “[t]he weaving pattern of the woven layer would be understood as having ridges and valleys” and that “[t]he ridges are in a first x-y plane and the valleys are in a second x-y plane” (Pet. 72), Petitioner does not specify where such ridges, valleys, and x-y planes are disclosed. Petitioner directs us to Sealey’s disclosure of “air channels 320 that extend in the X-Y plane of the fabric or belt” (Pet. 73 (quoting Ex. 1024 ¶ 139)) and annotates Sealey Figure 8 with a blue arrow identifying an alleged “elevated suspension of the nonwoven layer” (Pet. 74–75). But Petitioner’s arguments and evidence are not sufficient to show that Sealey’s fabric or belt has the ridges, valleys, and x-y planes recited in claim 1. The deficiencies in Petitioner’s contentions for independent claim 1, as discussed above, are not remedied by its contentions for dependent claims 2, 4, 5, 8, 9, 11, and 13. Pet. 75–78. For these reasons, we determine that Petitioner has not shown it is more likely than not that Sealey anticipates claims 1, 2, 4, 5, 8, 9, 11, and 13. 2. Section 325(d) Applying the Advanced Bionics two-part framework, we determine that Sealey is the same as the art previously considered by the Office during examination. See Prelim. Resp. 21–23, 33–34 (Patent Owner’s § 325(d) PGR2021-00019 Patent 10,584,444 B2 21 argument concerning Sealey). The Examiner rejected application claim 17 (corresponding to claim 1 of the ’444 Patent) as anticipated by Sealey. Ex. 1002, 55. In response, applicant argued that “Sealey discloses a woven layer that is substantially monoplanar” and “there are no voids between the woven and nonwoven layers.” Id. at 42 (providing annotation of Sealey Figure 10 with red dashed line showing single plane). Following this response, the Examiner allowed application claims 17–26 and 34–36 (corresponding to claims 1–13 of the ’444 Patent). See id. at 13 (Examiner’s indication of allowable subject matter). Under the second part of the Advanced Bionics framework, we determine that Petitioner has not demonstrated persuasively that the Office erred in its evaluation of Sealey in a manner material to the patentability of the challenged claims. The Petition includes no substantive discussion of the prosecution history and does not address whether the Examiner erred in evaluating Sealey. For the first time in the Reply, Petitioner argues that the Examiner and Patent Owner do not appear to have considered Sealey’s teaching that “both the extruded polymer netting . . . and woven layer . . . have non-planar, irregularly shaped surfaces.” Pet. Reply 3 (quoting Ex. 1024, ¶ 139; emphasis is Petitioner’s). We agree with Patent Owner that Sealey paragraph 139 is a description of Sealey Figure 8, which was substantively addressed during prosecution. PO Sur-reply 4; Ex. 1002, 42. Applicant argued that, in Sealey, “there are no voids between the woven and nonwoven layers,” and “[t]he lack of voids is illustrated in FIG. 8 of Sealey.” Ex. 1002, 42. After considering this argument, the Examiner allowed the claims. Ex. 1002, 13, 36, 42 (notice of allowability in response to applicant’s amendment and remarks distinguishing Sealey). Thus, the prosecution history does not PGR2021-00019 Patent 10,584,444 B2 22 support Petitioner’s assertion that the Examiner did not consider Sealey’s paragraph 139 teaching about non-planar, irregularly shaped surfaces. Petitioner identifies no other error in the Examiner’s evaluation of Sealey. F. JP ’238 Anticipation 1. Merits Petitioner contends that JP ’238 discloses a papermaking belt with a batt layer laminated to a base material. Pet. 83 (citing Ex. 1025 ¶ 9).10 Petitioner contends that the base material includes top layer 21 made from a nonwoven material and bottom layer 22 that is a woven fabric having “ridges in a first x-y plane and valleys in a second x-y plane.” Pet. 84–85 (citing Ex. 1025 ¶¶ 11, 21–23, Figs. 1, 2). Petitioner contends that the top surface of top layer 21 “can contact a web” and the bottom surface of the bottom layer 22 “can contact a machine surface.” Pet. 85 (citing Ex. 1025 ¶¶ 19, 25–28). Patent Owner argues that JP ’238 discloses web and machine contacting surfaces formed by felt batt layers, not the woven and nonwoven layers, as required by claim 1. Prelim. Resp. 59–60 (citing Ex. 1025 ¶¶ 15, 16, Fig. 1). We agree with Patent Owner. Claim 1 recites in pertinent part: the top surface of the first layer forming a portion of the web contacting surface of the belt, and the bottom surface of the second layer forming the machine contacting surface of the belt, wherein the first layer comprises a nonwoven material and the second layer comprises a plurality of woven ridges. 10 In several instances, the Petition cites JP ’238 using Exhibit 1016 instead of Exhibit 1025. Pet. 83, 85, 89. We cite the correct exhibit number. PGR2021-00019 Patent 10,584,444 B2 23 Ex. 1001, 18:5–10. The above-quoted claim limitation requires that the top surface of the nonwoven layer forms a portion of “the web contacting surface of the belt” and the bottom surface of the woven layer forms “the machine contacting surface of the belt.” Id. Patent Owner provides the following annotation of JP ’238 Figure 1: Prelim. Resp. 60. JP ’238 Figure 1 shows papermaking belt 10. Patent Owner’s annotations correctly identify, from top to bottom, batt layer 30, first reinforcing material 21, second reinforcing material 22, and another batt layer 30. Id.; Ex. 1025 ¶ 29. Petitioner identifies layer 21 as the claimed first layer comprising a nonwoven material and layer 22 as the claimed second layer comprising a plurality of woven ridges. Pet. 85. As shown in JP ’238 Figure 1, however, layers 21 and 22 are sandwiched between batt layers 30. Ex. 1025, Abstract (batt layer is laminated on a substrate composed of multiple sheets of reinforcing materials); ¶ 4 (“The papermaking felt includes a base material and a bat[t] layer, and the bat[t] layer includes a wet paper placement side layer and a press side layer.”); ¶¶ 9, 15, 29. PGR2021-00019 Patent 10,584,444 B2 24 After reviewing the portions of JP ’238 cited by Petitioner, we find insufficient support for Petitioner’s contention that that the top surface of top layer 21 “can contact a web” and the bottom surface of the bottom layer 22 “can contact a machine surface.” Pet. 85 (citing Ex. 1025 ¶¶ 19, 25–28). JP ’238 discloses polishing the surface of the first reinforcing material on the wet paper web side to adjust the void volume (Ex. 1025 ¶¶ 19, 25, Fig. 4), but does not disclose that this polished surface contacts the web. The deficiencies in Petitioner’s contentions for independent claim 1, as discussed above, are not remedied by its contentions for dependent claims 2–4, 8, 9, 11, and 12. Pet. 86–89. For these reasons, we determine that Petitioner has not shown it is more likely than not that JP ’238 anticipates claims 1–4, 8, 9, 11, and 12. 2. Section 325(d) Applying the Advanced Bionics two-part framework, we determine that JP ’238 is the same as the art previously considered by the Office during examination. See Prelim. Resp. 28–30, 33–34 (Patent Owner’s § 325(d) argument concerning JP ’238). The ’444 Patent claims the benefit of a Patent Cooperation Treaty (“PCT”) application, which was examined by the PCT International Search Authority (“ISA”) in Singapore. Ex. 1001, code (86); Ex. 1002, 251–257. In a written opinion, the ISA determined that application claims 17–26 are novel and involve an inventive step over JP ’238. Ex. 1002, 254–256 (reference D1 is JP ’238). Specifically, the ISA’s written opinion states: D1 differs from claim 17 in that D1 fails to disclose that the top surface of the first non-woven layer forming a portion of the web contacting surface and the bottom surface of the second woven layer forming a portion of the machine contacting surface. D1, instead, discloses web and machine contacting surface PGR2021-00019 Patent 10,584,444 B2 25 formed by batt layers (Ref. 30, Fig. 1) comprised in the felt. Starting from D1, it is not obvious to modify the papermaking felt to devoid of the batt layers. None of the cited prior art, either taken alone or in combination, teaches or suggests the invention of claim 17. Claim 17 therefore involves an inventive step. Id. at 255–256.11 During the U.S. national phase, applicant submitted a copy of the ISA’s written opinion as part of its request to participate in the Global/IP5 Patent Prosecution Highway pilot program. Id. at 84, 87, 94– 100. Applicant cited JP ’238 in an Information Disclosure Statement (“IDS”) and provided a translation. Id. at 104, 210–226. The Examiner initialed the citation of JP ’238, indicating it was considered. Id. at 64. Under the second part of the Advanced Bionics framework, we determine that Petitioner has not demonstrated that the Office erred in its evaluation of JP ’238 in a manner material to the patentability of the challenged claims. The Petition includes no substantive discussion of the prosecution history and does not address whether the Office erred in evaluating JP ’238. For the first time in the Reply, Petitioner argues that “the claims were never rejected over JP ’238” and “[t]he mere fact that JP ’238 was cited in an IDS, but not applied in any rejections, is insufficient to trigger the 35 U.S.C. § 325(d) bar.” Pet. Reply 7. We agree with Patent Owner that Petitioner fails to address the substantive discussion of JP ’238 in the ISA’s written opinion. PO Sur-reply 5–6; Ex. 1002, 255–256. The written opinion provides specific reasons why application claim 17 (corresponding to claim 1 of the ’444 Patent) is novel and involves an inventive step over JP ’238. Ex. 1002, 255–256. Petitioner identifies no error in the ISA’s evaluation of JP ’238. 11 PCT application claims 17–26 correspond to claims 1–10 of the ’444 Patent. Ex. 1002, 18, 85. PGR2021-00019 Patent 10,584,444 B2 26 G. Anticipation by Alleged Sales 1. Merits As support for its contention that forming fabrics MS015, LB003, and LB004 were “on sale” before the effective filing date of the ’444 Patent, Petitioner submits the declaration of it employee, Denise Weyers (Ex. 1009), along with invoices showing sales of these fabrics to GP in 2013 and 2015 (Exs. 1003–1005). As support for its contention that forming fabrics MS015, LB003, and LB004 meet the limitations of challenged claims 1–4, 6, 7, 9, and 11–13, Petitioner submits a declaration of its employee Timothy Lamers. Ex. 1013. Mr. Lamers relies on analyses performed by Petitioner’s Customer Service Lab on samples of MS015, LB003, and LB004 returned by GP (Exs. 1010–1012) and on measurements and photographs prepared by Petitioner’s employee, Timothy Schmidt (Exs. 1014–1016). Exhibit 1014 shows measurements of the MS015 sample returned by GP, and Exhibits 1015 and 1016 show measurements of replicates of the LB003 and LB004 fabrics sold to GP. Ex. 1013 ¶¶ 9, 10. Petitioner contends that forming fabrics MS015, LB003, and LB004 each have a nonwoven top layer and a woven bottom layer. Pet. 15–22. Petitioner contends that “the interlacing of the filaments . . . of the bottom layer results in nonplanar valleys and ridges, this being clearly evident from the cross-sectional figures of MS015, LB003, and LB004.” Pet. 23 (citing Exs. 1013–1015). Petitioner presents annotated cross-sectional images, which Petitioner contends show “the ridges and valleys of the first and second x-y planes according to claim 1.” Pet. 23–26. One such annotated image is reproduced below. PGR2021-00019 Patent 10,584,444 B2 27 Pet. 24. Petitioner represents that the above figure is a cross-sectional image of MS015 forming fabric. Pet. 23–24. Petitioner’s annotations identify a first x-y plane, a second x-y plane, and a void. Petitioner relies on the same annotated cross-sections to show “the void regions and suspended portions.” Pet. 27–29. Patent Owner argues that Petitioner does not identify a “plurality of woven ridges” or a “plurality of woven valleys” in the alleged sale fabrics. Prelim. Resp. 35–38. Patent Owner argues that Petitioner’s images depict woven structures that are “substantially monoplanar” and that the alleged sales “do not disclose the nonwoven layer having any ‘void spaces’ or ‘suspended portions’ lying above woven valleys, as claimed.” Id. at 49–50. Patent Owner argues that Mr. Lamers’ testimony is biased, uncorroborated, unreliable expert testimony of a lay witness, and hearsay to the extent it relies on testing performed by another employee, Mr. Schmidt. Id. at 67–83. Patent Owner argues that Petitioner’s evidence shows delamination, adhesive failure, and damage to the MS015 sample and there are “serious PGR2021-00019 Patent 10,584,444 B2 28 doubts” as to whether it accurately represents the MS015 product as sold in 2013. Id. at 71–72. Patent Owner argues that Petitioner has not established that the re-creations of the LB003 and LB004 fabrics are the same as the fabrics that were sold before the filing date of the ’444 Patent. Id. at 72–73. After considering the parties’ arguments and evidence, we determine that the Petition does not meet the threshold for institution of a post grant review based these alleged sales for several reasons. First, we agree with Patent Owner that Petitioner does not identify a “plurality of woven ridges” or a “plurality of woven valleys” in the alleged sale fabrics. Prelim. Resp. 35–38; Pet. 23–26. Petitioner provides cross- sectional images of the MS015, LB003, and LB004 fabrics with lines drawn to identify what Petitioner contends are first and second x-y planes. Pet. 24–26. But Petitioner does not provide annotations or other contentions sufficient to identify a “plurality of woven ridges” or a “plurality of woven valleys” in the alleged sale fabrics. The paragraphs of Mr. Lamers’ declaration that address ridges and valleys do nothing more than identify the weave pattern, regurgitate the claim language, and refer to Petitioner’s annotated cross-sectional images. Ex. 1013 ¶¶ 20, 21, 42, 43, 63, 64. The line labeled “second x-y plane” intersects various features, and Petitioner and its declarants do not explain how or why they determined the position of the alleged “second x-y plane.” Absent such an explanation, we cannot determine whether Petitioner’s annotated images show “a plurality of woven ridges lying in a first x-y plane and a plurality of woven valleys lying in a second x-y plane below the first x-y plane,” as recited in claim 1. Furthermore, Petitioner does not provide any cross-sectional images of the MS015, LB003, and LB004 fabrics that are not obscured by Petitioner’s annotations. The line Petitioner identifies as a “first x-y plane” covers the PGR2021-00019 Patent 10,584,444 B2 29 interface between the nonwoven and woven layers, and the line Petitioner identifies as a “second x-y plane” overlaps features of the woven layer. Pet. 24–26. Petitioner’s obscured images make it difficult to assess whether the alleged sale fabrics embody the claim limitations. Second, we agree with Patent Owner that Petitioner has not shown persuasively that the samples it relies upon accurately represent the fabrics that were allegedly sold to GP in 2013 and 2015. In the case of MS015, Patent Owner is correct that Petitioner’s evidence shows delamination, adhesive failure, and damage to the sample that was measured and photographed. According to Mr. Lamers, the MS015 sample that was measured and photographed (Ex. 1014) is from the belt that was returned by GP. Ex. 1013 ¶ 9. Mr. Lamers testifies that to his “best understanding and belief, no other alteration or testing was made to the sample(s) from the point of sale to Georgia-Pacific as described in the Albany invoice (Ex. 1003) and the evaluation and measurement of heights” described in his declaration and Exhibit 1014. Id. Mr. Lamers’ testimony is contradicted by Exhibit 1010—the “MS015 Belt Analysis” prepared by Petitioner’s Customer Service Lab when the belt was returned by GP in 2013. Ex. 1013 ¶ 7. According to that report, the MS015 belt “ran well for roughly 4.50 hours, and then it started to delaminate in two areas on the backside of the belt.” Ex. 1010, 1. The report states that “[i]n the seams near the center of the belt, it appears that the TPU sheet [the alleged ‘nonwoven’ layer] has shifted while the adhesive did not move” and “[a]s a result the adhesive is evident in the center of the TPU holes.” Id. The report includes captioned photographs evidencing damage, wear, abrasion, delamination, adhesive failure, and attempted repairs. Id. at 3–7. Contrary to Mr. Lamers’ representation, Exhibit 1010 shows that the MS015 sample that was PGR2021-00019 Patent 10,584,444 B2 30 measured and photographed in Exhibit 1014 is not in the same condition as when it was sold in 2013. Petitioner makes no attempt to explain how and why the sample it tested accurately represents the fabric that was sold, when the sample was taken from a worn and damaged belt that experienced delamination and adhesive failure. In the case of LB003 and LB004, we agree with Patent Owner that Petitioner has not shown sufficiently that the recreations of the LB003 and LB004 fabrics are the same as the fabrics that were sold before the filing date of the ’444 Patent. Petitioner acknowledges that the images of LB003 and LB004 in the Petition are “replicate fabrics.” See, e.g., Pet. 18. Mr. Lamers testifies that under his “direct supervision and control, and with the knowledge of the manufacturing of LB003 and LB004, replicate fabrics of LB003 and LB004 were made by Albany for the purposes of this petition for post grant review.” Ex. 1013 ¶ 10. According to Mr. Lamers, “[t]hese replicates accurately represent the forming fabrics LB003 and LB004 sold to GP.” Id. We find that Mr. Lamers’ testimony is merely conclusory and deserves little weight. Mr. Lamers provides no explanation of how he reached the conclusion that the replicates accurately represent the sold fabrics. Aside from his testimony that both the replicates and the sold fabrics have a nonwoven layer thickness of 1.00 mm (Ex. 1013 ¶¶ 35, 56), Mr. Lamers makes no other comparison between the replicates and the sold fabrics. Aside from Mr. Lamers’ conclusory testimony, Petitioner presents no other evidence that the replicates accurately represent the fabrics sold to GP in 2015. The deficiencies in Petitioner’s contentions for independent claim 1, as discussed above, are not remedied by its contentions for dependent claims 2–4, 6, 7, 9, and 11–13. Pet. 30–43. For these reasons, we determine that PGR2021-00019 Patent 10,584,444 B2 31 Petitioner has not shown it is more likely than not that the MS015, LB003, and LB004 fabrics sold to GP anticipate claims 1–4, 6, 7, 9, and 11–13. 2. Section 325(d) Patent Owner argues that the alleged sales are cumulative to art and arguments already considered by the Office, including Lefkowitz and Sealey. Prelim. Resp. 23. Patent Owner argues that Petitioner’s cross- sectional images of MS015, LB003, and LB004 are “visually indistinguishable” from Lefkowitz Figure 6 and Sealey Figures 8 and 11. Id. at 23–24. According to Patent Owner, the alleged sale fabrics and Sealey both utilize a similar 5-shed weave pattern in the woven layer. Id. at 24. Petitioner responds that “even where the woven layers of the sales fabrics have the same or similar weave pattern as Sealey and Lefkowitz (e.g., 5-shed), larger distances are apparent in the sales weaves between warp and weft fibers versus Sealey and Lefkowitz.” Pet. Reply 5. Petitioner contends that “[t]hese larger distances result in different ridge and valley heights and first and second x-y planes, thereby impacting other claim elements as well, such as void spaces.” Id. Petitioner asserts that, because of this difference in void height, the alleged sales, but not Sealey and Lefkowitz, are relied upon as anticipatory references for dependent claims 6 and 7. Id. Applying the Advanced Bionics two-part framework, we find that Petitioner does not sufficiently distinguish the alleged sales from the disclosures of Sealey and Lefkowitz, which were expressly considered by the Examiner, as discussed above. Petitioner does not deny that “the woven layers of the sales fabrics have the same or similar weave pattern as Sealey and Lefkowitz.” Pet. Reply 5. Although Petitioner disputes Patent Owner’s PGR2021-00019 Patent 10,584,444 B2 32 contention that the alleged sale fabrics are “visually indistinguishable” from Sealey and Lefkowitz and mentions “varying aperture widths” and different “contact points” (id.), Petitioner does not identify any specific difference as it pertains the limitations of claim 1. For example, Petitioner does not provide annotations or other contentions sufficient to identify a difference between the alleged sale fabrics and the fabrics disclosed in Sealey and Lefkowitz as it pertains the recitations of a “plurality of woven ridges” and a “plurality of woven valleys” in claim 1. Turning to dependent claims 6 and 7, we are not persuaded by Petitioner’s attempt to distinguish the alleged sales from Sealey and Lefkowitz based on void height. Pet. Reply 5. Petitioner does not assert that the fabrics disclosed in Sealey and Lefkowitz have a void height outside the ranges recited in claims 6 and 7. See Ex. 1001, 18:33–37 (claims 6 and 7). Instead, Petitioner merely asserts that Sealey “does not provide specific measurements” for void height. Pet. 79. Petitioner’s argument does not persuade us that the alleged sales are not substantially the same as Sealey and Lefkowitz, as it pertains to dependent claims 6 and 7. Thus, with respect to the alleged sales, we find that substantially the same art or arguments were previously presented to the Office. Addressing the second part of the Advanced Bionics framework, Petitioner relies on the same arguments for the alleged sales as it presented for Sealey and Lefkowitz. Pet. Reply 4–5. For the reasons discussed above, we determine that Petitioner has not demonstrated that the Office erred in its evaluation of Sealey or Lefkowitz in a manner material to the patentability of the challenged claims. PGR2021-00019 Patent 10,584,444 B2 33 H. Eagles Anticipation 1. Merits Petitioner contends that Eagles discloses a papermaking belt having a top nonwoven layer laminated to a bottom woven layer. Pet. 51–52, 55–56 (citing Ex. 1017, Abstract, ¶¶ 86, 87, Figs. 4A, 4B). Petitioner contends that Eagles Table 2 lists commercial fabrics manufactured by Petitioner, including J5076, Prolux U5076, and Electrotech 55LD. Id. at 53–55 (citing Ex. 1017 ¶ 80). Petitioner submits a second declaration of Mr. Lamers describing these fabrics and similar fabrics manufactured by Petitioner (Ex. 1018) and measurements and photographs of the fabrics (Ex. 1019). Petitioner contends that J5076 fabric “has a 5-shed weave pattern” and that “[a] 5-shed weave pattern has ridges and valleys.” Pet. 53 (citing Ex. 1018 ¶ 8). Petitioner illustrates its contention with the following figure. Pet. 53–54 (citing Ex. 102312). The above figure shows a 5 shed weave pattern. Petitioner’s blue arrows identify what it contends are a ridge (top arrow) and a valley (bottom arrow). Id. Petitioner contends that “[a] person of ordinary skill in the art would appreciate that the woven structure (bottom layer) structures disclosed in 12 Reprint of J. Plantikow, Forming Fabric Design Technology Continues to Evolve at Rapid Pace, Pulp and Paper, Oct. 1984. PGR2021-00019 Patent 10,584,444 B2 34 Table 2 laminated to an extruded (top) nonwoven layer would result in a void between the two layers at least because of the nonplanar ridge and valley conformation of the bottom woven layer and the distinctive nature of each layer.” Pet. 57 (citing Ex. 1017 ¶¶ 54, 55, 60–63, Table 2). Petitioner further contends that “[t]he belt would also have suspended portions of the top layer elevated in the z-direction over the valley portions of the bottom layer.” Id. (citing Ex. 1017 ¶¶ 52, 86, 87, 97, Table 2). Patent Owner argues that Eagles does not expressly describe any ridges, valleys, void spaces, or suspended portions. Prelim. Resp. 52, 54. Patent Owner argues that the fabrics listed in Eagles Table 2 are substantially monoplanar, lacking woven ridges and valleys, and that Petitioner provides no evidence that a skilled artisan would have understood these fabrics to have ridges and valleys. Id. at 53–57. In addition, Patent Owner argues that Eagles does not indicate whether the fabrics listed in Table 2 were publicly available, and Petitioner has not alleged that the fabrics were on sale. Id. at 54, 55 n.7. Patent Owner argues that Petitioner has not shown that using one of the fabrics listed in Eagles Table 2 as the woven layer would necessarily or inherently result in the claimed void spaces and suspended portions when the woven layer is laminated to a nonwoven layer. Id. at 51–53, 57–59. We agree with Patent Owner that Petitioner has not shown sufficiently that Eagles anticipates claim 1. Petitioner’s evidence is not sufficient to support its contentions that “[a] person of ordinary skill in the art would appreciate that the woven structure (bottom layer) structures disclosed in Table 2 laminated to an extruded (top) nonwoven layer would result in a void between the two layers at least because of the nonplanar ridge and valley conformation of the bottom woven layer and the distinctive nature of PGR2021-00019 Patent 10,584,444 B2 35 each layer” and “[t]he belt would also have suspended portions of the top layer elevated in the z-direction over the valley portions of the bottom layer.” Pet. 57 (citing Ex. 1017 ¶¶ 52, 54, 55, 60–63, 86, 87, 97, Table 2). The cited portions of Eagles describe the top and bottom layers of a multilayer belt and how the layers are joined together. Ex. 1017 ¶¶ 52, 54, 55, 60–63, 86, 87, 97, Table 2. Petitioner does not direct us to any description in Eagles of ridges, valleys, void spaces, or suspended portions. Petitioner offers no testimony to support its assertion about what a person of ordinary skill in the art would appreciate. Mr. Lamers testifies that “[t]he J5076 fabric has a weave pattern with both ridges and valleys” (Ex. 1018 ¶ 9), but that testimony is from the perspective of an employee of Petitioner with inside knowledge about the design of its products. Id. ¶ 7 (“I am familiar with J5076 as I worked with this fabric design for the creation of Albany’s first laminated samples, which then lead to the first laminated production belt.”); id. ¶ 12 (“To arrive at this data [regarding void height], I reviewed J5076 product information from 2009 to the present.”). Mr. Lamers does not testify about the fabrics listed in Eagles Table 2 from the perspective of a person of ordinary skill in the art. Petitioner does not present evidence sufficient to show that a person of ordinary skill in the art would have known or appreciated that J5076 or any of the other fabrics listed in Eagles Table 2 has ridges, valleys, or a void height. Nor does Petitioner establish that the fabrics were on sale, in public use, or otherwise publicly available or that the information about the fabrics was publicly available. Furthermore, Petitioner does not show sufficiently that using one of the fabrics listed in Eagles Table 2 as the woven layer would necessarily or inherently result in the claimed void spaces and suspended portions when the PGR2021-00019 Patent 10,584,444 B2 36 woven layer is laminated to a nonwoven layer. Mr. Lamers determines void heights based solely on information about the woven fabrics. Ex. 1018 ¶¶ 11–16; Ex. 1019. Eagles discloses that the woven and nonwoven layers can be joined together using a variety of techniques, including an adhesive, heat welding, ultrasonic welding, and laser fusion. Ex. 1017 ¶¶ 86, 97. Petitioner does not show that each of these techniques would necessarily result in the void spaces and suspended portions recited in the claim. The deficiencies in Petitioner’s contentions for independent claim 1, as discussed above, are not remedied by its contentions for dependent claims 2–9, 11, and 12. Pet. 58–67. For these reasons, we determine that Petitioner has not shown it is more likely than not that Eagles anticipates claims 1–9, 11, and 12. 2. Section 325(d) Applying the Advanced Bionics two-part framework, we determine that Eagles is the same as the art previously considered by the Office during examination. See Prelim. Resp. 26–28, 33–34 (Patent Owner’s § 325(d) argument concerning Eagles). Applicant disclosed Eagles in an IDS, and the Examiner initialed the citation, indicating that Eagles was considered. Ex. 1002, 22, 30. Applicant also disclosed U.S. Patent No. 9,957,665, which issued from the application that published as Eagles, and the Examiner initialed the citation, indicating that the Eagles patent was also considered. Id. at 63. As discussed above, the ’444 Patent claims the benefit of a PCT application. Ex. 1001, code (86). Eagles was substantively addressed in an anonymous Third Party Observation during prosecution of the PCT application. Ex. 2002, 1–2. The Third Party Observation includes a list of PGR2021-00019 Patent 10,584,444 B2 37 the most relevant passages and drawings, as well as a brief explanation of the relevance of Eagles. Id. at 2. According to the Third Party Observation, Eagles discloses a multilayer belt for tissue-making, where “[t]he belt comprises a machine side bottom woven layer comprising yams interwoven to form ridges and valleys lying in different x-y planes.” Id. The Third Party Observation asserts that “per definition” a void exists between the extruded polymeric top layer and the woven bottom layer “because of the ridge valley construction of the woven layer coupled with the distinctive nature of each layer.” Id. According to the Third Party Observation, Eagles “inherently discloses a void height falling within the claimed range in view of the woven products and size of the warp threading in Table 2.” Id. The Third Party Observation asserts that Eagles discloses independent claim 17, which corresponds to claim 1 of the ’444 Patent. Id.; Ex. 1002, 18, 85. Applicant disclosed the Third Party Observation in an IDS. Ex. 1002, 31. The Examiner lined through the citation “because it is an incomplete citation (no author or date).” Id. at 14, 23. Nevertheless, the Examiner stated that the Third Party Observation “has been placed in the application file, and the information referred to therein has been considered as to the merits.” Id. at 14. Although Petitioner suggests that Eagles was not substantively examined (Pet. Reply 6), Petitioner’s suggestion is belied by the file history, which indicates that the Examiner substantively considered both Eagles and the Third Party Observation. Ex. 1002, 14, 22, 23. Petitioner argues that the Third Party Observation cited Eagles Table 2 “only in the context of inherently anticipated warp threading to establish a void height” and that Petitioner’s “evidence regarding weave patterns of the Table 2 fabrics” is “material information not considered by the examiner.” Pet. Reply 6. We PGR2021-00019 Patent 10,584,444 B2 38 disagree. As discussed above, Petitioner offers no testimony to support its assertion about what a person of ordinary skill in the art would appreciate from reviewing Eagles. Petitioner does not show sufficiently that using one of the fabrics listed in Eagles Table 2 as the woven layer would necessarily or inherently result in the claimed void spaces and suspended portions when the woven layer is laminated to a nonwoven layer. For these reasons, Petitioner does not show that its evidence regarding weave patterns of the Table 2 fabrics is material to patentability. Under the second part of the Advanced Bionics framework, we determine that Petitioner has not demonstrated that the Office erred in its evaluation of Eagles in a manner material to the patentability of the challenged claims. Petitioner does not attempt to demonstrate error apart from its challenge on the merits, which does not persuade us for the reasons discussed above. I. Obviousness Grounds 1. Merits Petitioner challenges dependent claims 3, 5–8, 10, 12, and 13 based on various obviousness grounds. Pet. 4–5. The deficiencies in Petitioner’s anticipation grounds with respect to independent claim 1, as discussed above, are not further addressed or otherwise remedied by Petitioner’s obviousness grounds for these dependent claims. Pet. 44–50, 67–69, 79–83. Furthermore, we agree with Patent Owner that the Petition lacks sufficient argument and evidence to show a motivation to combine the prior art relied upon to show obviousness. Id.; Prelim. Resp. 62–66. In some cases, Petitioner invokes design choice or routine, customary, or obvious choice, without providing an explanation or citing evidence to establish why PGR2021-00019 Patent 10,584,444 B2 39 a person of ordinary skill in the art would have made that choice. Pet. 48, 50, 68, 80, 83. In other cases, Petitioner provides no reasoning whatsoever to support Petitioner’s proposed combinations of prior art elements. Pet. 69 (claim 13; Eagles, alleged sales); Pet. 79, 81 (claims 3, 12; Sealey, Eagles). Merely stating that a claim limitation is a design choice does not make it obvious. Petitioner “must offer a reason for why a person of ordinary skill in the art would have made the specific design choice.” See Cutsforth, Inc. v. MotivePower, Inc., 636 F. App’x 575, 578 (Fed. Cir. 2016) (requiring the Board to offer such a reason); see also KSR, 550 U.S. at 418 (obviousness inquiry requires consideration of whether there was “an apparent reason to combine the known elements in the fashion claimed by the patent at issue”). Petitioner’s obviousness grounds are deficient for this reason, separate and independent from the deficiencies discussed above for Petitioner’s anticipation grounds. Accordingly, we determine that Petitioner has not shown it is more likely than not that dependent claims 3, 5–8, 10, 12, and 13 are unpatentable for obviousness. 2. Section 325(d) Patent Owner argues that Stone, which Petitioner relies upon as a secondary reference for claim 10, is cumulative of another reference— Aberg13—that was considered during prosecution. Prelim. Resp. 31. Petitioner disputes that contention, arguing that Stone does not disclose subject matter (non-discrete layers) applicant relied upon to distinguish Aberg. Pet. Reply 7. 13 Ex. 2001, Aberg et al., US 2011/0272112, published Nov. 10, 2011. PGR2021-00019 Patent 10,584,444 B2 40 We disagree that Petitioner has sufficiently distinguished the disclosure of Stone from that of Aberg. Patent Owner is correct that Petitioner relies on Stone for the same subject matter—polyphenylene sulfide (“PPS”) as a woven layer material—for which the Examiner relied on Aberg. Prelim. Resp. 31–32; Pet. 49–50 (asserting that claim 10 is unpatentable because it would have been obvious to make the woven layer from PPS, citing Stone (Ex. 1020)); Ex. 1002, 56–57 (Examiner’s rejection of application claim 2614 asserting that it would have been obvious to make a papermaking belt using the polymeric materials disclosed by Aberg for the woven layer, including PPS). Even if Petitioner is correct that applicant’s argument about Aberg does not apply to Stone (Pet. Reply 7), that does not sufficiently distinguish Stone. Petitioner relies upon Stone solely to teach the subject matter of dependent claim 10, which recites that the woven layer is formed from PPS. Pet. 49–50, 67–68, 82–83. Applying the Advanced Bionics two-part framework and for the reasons discussed above, we determine that the art relied upon in Petitioner’s obviousness grounds—the alleged sales, Eagles, Stone, and Sealey—is either the same or substantially the same as the art previously considered by the Office during examination. Under the second part of the Advanced Bionics framework, we determine that Petitioner has not demonstrated that the Office materially erred in its evaluation of this art. Petitioner does not attempt to demonstrate error apart from its challenges on the merits, which do not persuade us for the reasons discussed above. 14 Application claim 26 corresponds to claim 10 of the ’444 Patent. Ex. 1002, 18. PGR2021-00019 Patent 10,584,444 B2 41 III. SUMMARY AND CONCLUSION For the above reasons, we determine that Petitioner has not established that it is more likely than not that it would prevail in showing that claims 1–13 of the ’444 Patent are unpatentable on the grounds asserted in the Petition and that we should also exercise our discretion under 35 U.S.C. § 325(d) to deny the Petition, which provides an additional reason for denying institution. IV. ORDER It is ORDERED that, the Petition is denied, and no trial is instituted.
