      “We question, therefore, whether someone having an education in textile engineering or physics, but no experience in the field of hunting blinds, would be consistent with the level of skill portrayed by the ’535 Patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We note that Petitioner’s expert’s experience, education, and qualifications are rooted in textiles, fibers and physics, and sophisticated subjects related thereto. See Ex. 1007 ¶¶ 14–20. But his deposition revealed that he has little or no experience in the field of hunting blinds. See Ex. 2038, 8–14.5 5 The same might be said of Patent Owner’s expert. See Ex. 2031, ¶¶ 6–7; Ex. 1023, 16. However, our obviousness analysis leaned lightly, if at all, on her declarations and testimony.” slip op. at 12

      “1. Mesh Material In the Petition, Petitioner asks that “the term ‘mesh material’” be interpreted in accordance with “a plain and ordinary usage.” Pet. 25. Per Petitioner, the “plain and ordinary” meaning of the term “mesh material” is “a woven material of open texture with spaced holes therein.” Id. Per Petitioner, “[o]ther typical terms used to describe a mesh-like material” are “a screen material, or a netting material, which are believed to be synonyms.” Id. Patent Owner does not dispute that a mesh material would have an open texture with spaced holes therein. See PO Resp. 18. We find that Petitioner’s proposed construction aligns with the ’535 Patent’s specification. See Ex. 1001. The drawings in the ’535 Patent depict the mesh material 26 as having an array of uniformly spaced circular holes forming a net-like structure (see id., Fig. 1A, 1B, 4, 9) or an array of uniformly spaced rectangular openings (see id. Fig. 8) forming a screen-like structure. The embodiments of the mesh material 26 listed in the ’535 Patent (e.g., a mesh banner material, scrims, a network of fibers, etc.) are materials having net-like or screen-like structures. See id. at 6:47–7:28.6” slip op. at 14

      “Our construction aligns with the claim language; Petitioner’s proposed construction does not. See Ex. 1001, 10:4–19. The independent challenged claims set forth “one or more panels of mesh material” and then set forth “said one or more panels comprising: a first side with a camouflage pattern; and a second side with a dark color coating.” Id. at 10:4–11. The recited “said one or more panels” corresponds to the previously recited “one or more panels of mesh material,” not panels comprising a material that was only a “mesh” prior to printing/coating. See id. Also, the independent challenged claims set forth that “the one or more panels of the mesh material define an outer surface of the camouflage structure.” See id. at 10:18–19, 1:23–24 (emphasis added). And the panel(s) defining a hunting blind’s outer surface would include the dark color coating. Our construction aligns with the ’535 Patent’s specification; Petitioner’s proposed construction does not. See Ex. 1001. The ’535 Patent repeatedly describes the relevant panel material in the hunting blind (i.e., post printing/coating) as a mesh material. See id., Abst., 1:19–5:34, 6:47–7:28, 9:16–54, Figs. 1A, 1B, 9. The ’535 Patent expressly describes and depicts the mesh material 26 as including the camouflage pattern and the dark-color coating. See id. at 1:52–56, 3:24–25, 3:31–33, Figs. 1A, 1B. The ’535 Patent says that “panels” of this coated mesh material 26 “are used to form” a hunting blind. Id. at 3:22–26. The ’535 Patent says that “[m]esh material is presented for a hunting blind with a camouflage pattern printed on a first side and a second side with a color coating.” Id. at Abst. The ’535 Patent says that “mesh material of interwoven fabric is provided for a hunting blind including a camouflage pattern printed on a first side and a second side with a dark color coating.” Id. at 1:19–22; see also id. at 1:44–49. Our construction aligns with the ’535 Patent’s prosecution history; Petitioner’s proposed construction does not. See Ex. 1006. As mentioned above, throughout prosecution of the ’535 Patent, the same prior art material was mapped to the claimed panel(s) of mesh material. See Ex. 1006, 64–72, 122–106. The mapped-to prior art mesh material was described during prosecution as an “interwoven fabric” with “a pattern” printed on a first side and “a dark color coating” on a second side. Ex. 1006, 64; see also id. at 122. And the mapped-to prior art mesh material (i.e., which included not only the interwoven fabric but also the printed pattern and the dark color coating) had a “net-like structure” with an array of uniformly spaced “net holes” that are “not closed.” Ex. 2021, 4:1–5, see also id. at 2:58–3:6, 4:34–45, Figs. 1, 2a. Thus, we understand that claimed panel(s) of mesh material must have” slip op. at 17

      “However, Patent Owner does not bear the burden of proving Strength’s camouflage material 10 does not have holes. Rather, Petitioner bears the burden of proving that Strength’s camouflage material 10 does have holes. And Petitioner’s arguments that undermine Patent Owner’s position that Strength’s camouflage material 10 does not have holes, concurrently undermine Petitioner’s position that Strength’s camouflage material 10 does have holes. Per Petitioner, “Strength is silent on whether visible holes exist in the fabric” (Pet. Reply 8) and “the Strength reference doesn’t discuss anything about holes” (Tr. 14). Petitioner’s expert testified that it was his “understanding that Strength is silent” on “whether or not there are holes.” Ex. 2038, 44. Petitioner contends that Strength’s silence about the presence/ absence of holes hinders Patent Owner from proving that Strength’s camouflage material 10 does not have holes. See Pet. Reply 8. We agree. But this same silence likewise hinders Petitioner from proving that Strength’s camouflage material 10 does have holes.” slip op. at 35

      “It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016) (quoting 35 U.S.C. § 312(a)(3)). Here, however, not until its Reply does Petitioner belatedly suggest that Ferrante’s disclosure of bone screws with self-tapping ends equally meets the limitation of claim 10 (with respect to the first member) as with claim 11 (with respect to the second member), and that both claims are obvious in light of “evidence” from Ferrante “that it was well known to equip bone screws with self-tapping ends.” Reply 26–27. We do not discern these arguments in the Petition, and consider them waived. See Netflix, Inc. v. DivX, LLC, 84 F.4th 1371,1377 (Fed. Cir. 2023) (“While the Board should not take an overly mechanistic view of a petition and decline to address an argument because the petitioner did not present it with ideal vigor and clarity, the Board should also not have to decode a petition to locate additional arguments beyond the ones clearly made.”). In sum, Petitioner’s error in failing to first address limitations of claim 10 in the Petition specific to the Cognet/Ferrante combination indicates a failure to meet the particularity requirements for what must be in the petition and cannot be left to be filled in on reply. See 35 U.S.C. § 312(a)(3); 37 C.F.R. §§ 42.22(a)(2) (requiring, among other things, “a detailed explanation of the significance of the evidence”), 42.104(b)(4)–(5) (requiring that petition “specify where each element of the claim is found in the prior art patents or printed publication relied upon” and, regarding submitted evidence, state “the relevance of the evidence to the challenge raised, including identifying specific portions of the evidence that support the challenge”). Microsoft, 2022 WL 989403, at *6.

      “We also find persuasive Mr. Dominguez’s explanation that one of ordinary skill in the art would have understood “bore” as including stepped diameter holes, sometimes described as a bore having a counterbore. See generally Ex. 1018 ¶¶ 4–29; Reply 3–10. Three of Mr. Dominguez’s illustrative examples are reproduced in the annotated figures below. The above figures show Mr. Dominguez’s annotated illustrations from the Jackson (Ex. 1019, Fig. 3), Brånemark (Ex. 1021, Fig. 4), and Ray (Ex. 1025, Fig. 1) references as discussed at paragraphs 10, 12, and 13, respectively, of Mr. Dominguez’s Second Declaration. With reference to the above figures, Mr. Dominguez testifies that “Jackson describes a bone repair set screw in which ‘[t]he bore 27 comprises a first bore section 31, a second bore section 32,’ etc. delineated by shoulders 41, 42, etc. (Ex. 1019, 5:24– 43)” (Ex. 1018 ¶ 10); “Brånemark describes an osseous implantation device having body 1ʺ with first and second holding portions 21ʺ, 31ʺ and ‘an inner through bore with a first portion 4ʺ in the first holding portion and a second portion 5ʺ in the second holding portion.’” Ex. 1021, 4:44–46” (id. ¶ 12); and Ray discloses surgical calipers including “handle 12 having ‘stepped cylindrical bore 14,’” wherein “[c]ollar 20 of a shaft inserted in the bore ‘rests against a step of the bore 14’ (2:14–15)” (id. ¶ 13). Patent Owner responds that Mr. Dominguez’s examples “that allegedly show a single bore encompassing two or more stepped-diameter holes or a counterbore . . . . are specific to these references and divorced from the disclosures of the ’166 patent.” Sur-Reply 7. Insofar as the ’166 patent makes no mention of the term “bore” outside the claims, and Mr. Dominguez’s examples are all taken from the field of orthopedic surgery, we do not find this argument persuasive. Patent Owner further appears to contend that exemplary references to a “cylindrical stepped down bore” or a “stepped cylindrical bore” are too specific to be within the scope of the term “bore.” Sur-Reply 7–8. As these terms merely describe species within a larger genus, and Patent Owner presents no cogent reason to exclude them, we do not find this argument availing. Relatedly, we are also not persuaded by Patent Owner’s argument that “the prior art treats a ‘bore’ as an element that is distinct from a ‘counterbore.’” Id. at 8. Rather, we credit Mr. Dominguez’s testimony that “[a] counterbore is not a structure unto itself, a counterbore is part of a larger structure” as exemplified by numerous examples including Laps (Ex. 1028 ¶ 33 (sensor assembly wherein “bore 16 includes a counterbore 18”)); Martinez (Ex. 1029, 3:61 (surgical cutting instrument wherein “bore 56 has a counterbore 64”)); Zang (Ex. 1030, 2:49 (bone anchor having a “bore [that] includes a counterbore”)); Ledet (Ex. 1022, 29:3–5 (vertebral fixation plate having “through holes . . . . countersunk, or counterbored to accommodate the head of a bone screw”)); Seo (Ex. 1031, 3:45 (chair leg employing “counterbored bore 23”)); and Exner (Ex. 1032, 2:16 (extrusion press including “counterbored axial bore 6”)). Ex. 1018 ¶¶ 17–23. That a reference may refer to a figure as showing “bore 103” with “counterbore 105 . . . formed on one end” does not indicate that they are distinct structures as Patent Owner contends, but merely that the focus of each term is directed to the entire bore or to a particular aspect of the bore, i.e., its counterbore.

      “Patent Owner subsequently proposed an alternative definition, as a person having “[a] Bachelor’s Degree in biomedical and/or mechanical engineering or similar training and . . . at least three years of experience with implant devices used for internal fixation of bones.” POR 5 (citing Ex. 2012 ¶¶ 32–33). According to Patent Owner, “[t]his hypothetical person would be capable of performing various design tasks and would understand the basic mechanical features and operation of orthopaedic implant devices [and] have an appreciation for orthopaedic fusion techniques and the medical issues and concerns faced by a doctor/surgeon charged when performing operations to implant orthopaedic devices.” Id. Despite some differences in wording, Patent Owner asserts (and Petitioner does not contest) that any “distinction between the parties’ proposed definitions of a POSITA does not affect the arguments set forth herein.” Id. (citing Ex. 2012 ¶ 34). Consistent with this view, we find the parties’ constructions equally applicable in light of the prior art of record and the disclosure of the ’166 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” as evidence of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)).

      “one of ordinary skill in the art would understand that “bore,” as used in the context of claims 1 and 12, encompasses a multi-diameter passage, and in particular, one having stepped longitudinal cross sections such as that shown in Cognet’s Figure 1. See generally DI 11–13. For the reasons that follow, we conclude that one of ordinary skill in the art would have understood “bore” as such. Relying on the testimony of Mr. Dominguez, Petitioner initially proposed a construction of “bore” as “a usually cylindrical hole made by or as if by the turning or twisting movement of a tool.” Pet. 16 (citing Ex. 1002 ¶ 58). Petitioner’s proposal relied on Mr. Dominguez’s testimony that “[a] bore is a cylindrical hole made by the spinning rotation of a twist drill cutting tool. It is typically made by removing material from a solid or hollow object, similar to a tunnel or orifice.” Ex. 1002 ¶ 58. Pointing to its annotation of Cognet’s Figure 1, above, Patent Owner argued that that the term “bore” excludes a tunnel made by “two adjacent bores.” See Prelim. Resp. 21–25. In view of the then-available evidence, we provisionally construed “bore” as a hole or passage made by or as if by the turning or twisting movement of a tool such that its interior walls have cylindrical lateral cross-sections, and which do not exclude holes or passages having tapered or stepped longitudinal cross-sections.

This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway.

      “Marshall (alone and with Phillips and Webb) when addressing the claims added during prosecution that ultimately issued as the Challenged Claims.” Pet. 68. As pointed out by Petitioner, “Marshall was never considered by the Examiner” against the claims that ultimately issued as claims 1–13 of the ‘050 Patent. Pet. 67, see also Ex. 1008, 263–289, 323–353. As also pointed out by Petitioner, “even when the Examiner considered Marshall” against claims that were subsequently cancelled, “he considered Marshall only as a secondary reference.” Pet. 67, see also Ex. 1008, 203–236, 263–289, 323–353. Patent Owner argues that Petitioner “fails to provide an adequate explanation as to how the examiner erred.” Prelim. Resp. 22. Patent Owner contends that Petitioner’s explanation “makes no sense,” and is “both conclusory and uncompelling.” Id. We disagree with Patent Owner’s characterization of the Petitioner’s position, especially because it is supported by prosecution history of the ’050 Patent. (See Ex. 1008, 203–236, 263–289, 323–353.) Patent Owner also argues that the prosecution history of the ‘050 Patent “establishes that the Examiner reviewed Marshall thoroughly and applied it against the claims, some of which he rejected and other he later allowed.” Id. at 21. To support this argument, Patent Owner points to findings made by the Examiner during prosecution of the ‘050 Patent. See id. at 20. These findings, however, related to the Examiner’s rejections against claims that were subsequently cancelled. See Ex. 1008, 203–224. And these findings were made in conjunction with Marshall being applied as a secondary reference to reject those claims. See id. The Examiner rejected those claims over a combination of three prior art references (Kessler, Delany, and Tidwell), and added Marshall, in lieu of using official notice, to show that it was known in the art to configure a processor to execute computer executable instruction stored in a memory. See id. at 211–214. Thus, these findings do not contradict Petitioner’s position that overlooking Marshall as primary obviousness reference in connection with the Challenged Claims was a material error. The prosecution history does not sufficiently show that the Examiner considered Marshall, Philips, Web, or the combinations of these references asserted in the Petition, with respect to the claims that issued as the ’050 Patent. In particular, the Examiner asserted as Reasons for Allowance that the prior art did not teach” slip op. at 15

    • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

      “Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). Petitioner, supported by the testimony of Dr. Ravetch, contends that Bowdish is analogous art. Pet. 36–37 (citing Ex. 1003 ¶ 128). In this respect, Dr. Ravetch testifies: A POSA looking for the amino acid sequences encoding eculizumab would have easily found Bowdish, and considered it to be analogous art to Bell and Evans for at least three reasons: (1) it provides express disclosures about the structure of the antibody “5G1.1,” (2) it identifies “Alexion Pharmaceuticals” as the inventors’ addressee that is the same as the assignee for Evans, and (3) it cites to the same Evans patent as does Bell for the structure of 5G1.1. Thus, a POSA would have been motivated to combine the teachings of Bowdish and Evans in view of Bell to arrive at the claimed sequence. Ex. 1003 ¶ 128. On the present record before us, it appears that Bowdish is both reasonably pertinent and within the same field of endeavor as the ’809 patent for the reasons identified by Dr. Ravetch, because it is directed to the construction of a humanized monoclonal antibody comprising a TPO mimetic peptide graft into the heavy chain CDR3 of antibody framework 5G1, and because it uses “the parental 5G1.1” sequence as a control for FACs analysis of the TPO mimetic antibody. See Ex. 1004 ¶¶ 191–193. Moreover, it is reasonable that an ordinarily skilled artisan seeking to understand the Alexion anti-C5 antibody disclosed in, for example, Bell or Hillmen or Hill as a treatment for PNH, would look to other Alexion prior art for guidance.” slip op. at 42

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightMotivation foundDecided for petitioner

      “overarching argument that Petitioner’s positions are fatally flawed by hindsight or that “[a] POSA as of March 15, 2007[,] would have understood that Alexion had developed a humanized antibody named ‘eculizumab,’ . . . [b]ut a POSA at that time would not have known that “eculizumab” had the sequence claimed in the ʼ809 patent.” See Prelim. Resp. 4, 7, 9. It appears that Petitioner’s positions here consider only the disclosures of the prior art and how the person of ordinary skill in the art would have read prior art references in view of one another. Regarding Patent Owner’s foundational preliminary argument that all prior art pointed exclusively to Thomas for the structure of eculizumab, rather than to Evans or Tacken or Mueller PCT, for example, we are unconvinced. We find Patent Owner’s position mischaracterizes Bell’s incorporation of Thomas by wholly ignoring that, in the very same sentence, and preceding the cite to Thomas, Bell also incorporates Evans by reference. Ex. 1007 ¶ 52. Bell incorporates Evans as disclosing “[p]articularly useful anti-C5 antibodies . . . h5G1.1-mAb, h5G1.1-scFv and other functional fragments of h5G1.1,” and “[m]ethods for the preparation” of these. Id. It appears that the ordinarily skilled artisan, like Bell’s inventors, would not have looked solely to Thomas for eculizumab’s structure. Moreover, the ’809 patent itself states that Evans, which is a part of Bell, discloses “a preferred whole antibody (now named eculizumab),” and how to produce it. See, e.g., Ex. 1001 12:34–37. Thus, even the ’809 patent, like Bell, acknowledges that Evans is an important reference regarding eculizumab, its structure, and how to make it.” slip op. at 43
