      “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. Accordingly, Petitioner has not shown persuasively that claim 11 would have been obvious in light of Cognet and Ferrante for the reasons set forth in the Petition. slip op. at 41

      “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)). We adopt, for convenience, Petitioner’s definition, but our analysis does not change depending on which of the two articulations are applied here. H.” slip op. at 12

      “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.

      “Petitioner contends that a person of ordinary skill in the art at the time of the invention (“POSA” or “POSITA”) would have had “a bachelor’s degree and two or more years of experience or a master’s degree in organic synthesis or chemical engineering, with education substituting for experience and vice versa.” Pet. 15 (citing Ex. 1002 ¶ 16). Patent Owner took no position on the level of ordinary skill in the art in its Preliminary Response. Prelim. Resp. 8. In our Institution Decision, we adopted Petitioner’s definition. Dec. Inst. 6–7. In its Motion to Amend, Patent Owner states that it accepts the Board’s definition for purposes of this proceeding. MTA 24. We, therefore, see no reason to disturb our definition of the level of ordinary skill in the art as it appears to be consistent with the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Although neither party expressly proposes a construction for the term “conversion,” the parties appear to differ in their interpretations of that term. Petitioner interprets “conversion” to mean the percent conversion of the 1- alcohol. See Pet. Opp. RMTA 6–7 (interpreting “conversion” as percentage of remaining 1-alcohol); Ex. 1040, 109:2–11. Patent Owner, on the other hand, interprets “conversion” to mean the total percentage of alkenes that have been produced. Ex. 2010 ¶ 123 (interpreting “conversion” as percentage of total alkenes). During oral argument, counsel for Patent Owner conceded that “conversion can mean either.” Tr. 27:18–28:13. Without the benefit of briefing by the parties, we decline to expressly construe the term “conversion,” as our Decision would be the same under either interpretation, as discussed further below. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “2. Analysis A patent claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which said claimed invention pertains. See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of 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 skill in the art; and (4) objective evidence of nonobviousness.

Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. 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. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it. See Ex. 1047 ¶¶ 10, 25–26, 53; Ex. 2013, 2:10–18; Ex. 2014, 2:12–20; Ex. 2015 ¶ 3; Ex. 2025, 2:10–18; Ex. 2078, 267.” slip op. at 32

      “We adopt the same reasoning here, and conclude that the evidence of record and the Specification of the ’681 patent support construing the preamble’s recitation of a “method for treating a patient with an angiogenic eye disorder” as meaning administering a compound, i.e., the recited VEGF antagonist, to a patient for the purpose of improving or providing a beneficial effect in their angiogenic eye disorder. We find that, as in Eli Lilly & Co. v. Teva Pharms. Int’l GmbH, although the claims “encompass a clinical result, they do not require such a result.” (emphasis added). 8 F.4th 1331, 1343 (Fed. Cir. 2021). We consequently reject Patent Owner’s proposed construction that the language of the preamble reciting a “method for treating an angiogenic eye disorder” requires not only an intent to treat, but, additionally, a high degree of efficacy on par with monthly Lucentis.

      “We adopt Petitioner’s proposed construction of the claim terms “initial dose,” “secondary dose,” and “tertiary dose.” Petitioner proposes adoption of the definitions expressly set forth in the Specification of the ’681 patent, viz., that the initial dose is the dose “administered at the beginning of the treatment regimen,” and is followed by the secondary doses that are “administered after the initial dose,” and the tertiary doses are “administered after the secondary doses” and may be distinguished from the secondary doses “in terms of frequency of administration.” Ex. 1001, col. 3, ll. 36–44. Patent Owner does not expressly dispute Petitioner’s construction, other than to argue that, by 2011, a person of ordinary skill in the art would have understood “initial” and “secondary” doses to correspond to loading doses and “tertiary” doses to correspond to maintenance doses. PO Resp. 13 (citing Ex. 2056 ¶ 66; Ex. 2349, 6–11. Patent Owner contends that the purpose (and expected effect) of loading doses was to achieve visual acuity gains and retina drying, and the goal of less frequent maintenance doses was to maintain the efficacy achieved with loading doses. Id. at 14 (citing Ex. 2056 ¶ 66). As we have explained above, we do not find persuasive Patent Owner’s argument that the definition of these terms requires a high, or otherwise defined, degree of efficacy. As we stated in the -00881 and -01225 Decisions: Based on those express definitions in the Specification, we do not find cause to construe the terms differently. In particular, we do not find that the Specification requires the “tertiary doses” to maintain any efficacy gain achieved after the initial and secondary doses, or that the term suggests any specific level of efficacy. The Specification unequivocally states that “[t]he terms ‘initial dose,’ ‘secondary doses,’ and ‘tertiary doses,’ refer to the temporal sequence of administration of the VEGF antagonist.”” slip op. at 18

      “If a claim limitation is directed to printed matter, the second step of the Praxair analysis is to determine whether the printed matter is functionally related to its “substrate.” Praxair, 890 F.3d at 1032. Printed matter that is functionally related to its substrate is given patentable weight. Id. (citing DiStefano, 808 F.3d at 850). However, “[w]here the printed matter is not functionally related to the substrate, the printed matter will not distinguish the invention from the prior art in terms of patentability.” Id. (quoting In re Ngai, 367 F.3d 1336, 1339 (Fed. Cir. 2004)). More specifically, printed matter is functionally related to its substrate when the language changes not mere thoughts or outcomes, but provides action steps that the method requires. See C R Bard Inc. v. AngioDynamics, Inc., 979 F.3d 1372, 1381 (Fed.

Ben Venue Laboratories, Inc., 246 F.3d 1368, 1376 (Fed.

In the -01225 IPR, we adopted the same definition of a person of ordinary skill in the art for the challenged claims of the ’681 patent, concluding that that definition was consistent with the level of skill in the art.

      “and DTS are provided in optional fields of packetized elementary stream packets. Ex. 1005, 7:19–25. Further, “[t]he video DTS . . . indicates the time when the picture needs to be decoded by the STD” (Ex. 1005, 7:47– 49), and on the current record, we understand Petitioner to cite the DTS parameters encoded in the transport stream for enhancement layer pictures as teaching the claimed coded information representing a desired delay time. Pet. 33. Among other examples, Petitioner (Pet. 34) and Dr. Reader (Ex. 1005 ¶ 201) cite Chen-736’s example of the formula DTSEi = DTSLi +1.5F, where F is a time interval based on the frame rate (Ex. 1005, 8:9–20), as indicating that DTSEi represents the start of decoding of the ith picture in the enhancement layer being delayed 1.5F relative to the start of decoding of the ith picture frame of the base layer. Pet. 36 (citing Ex. 1003 ¶ 201); see Pet. 35–40 (citing additional examples of serial and parallel decoding with similar DTS calculations). At this stage, we find Petitioner’s position that the claim’s recitation that the coded information must “represent” the desired delay time to be a reasonable reading of the plain language of the claim such that a DTS value can represent the desired delay time even if it requires calculation. Pet. 35 n.8. Even if Chen-736’s use of F-based offsets as time intervals “is different than the concept of a desired delay between decoding” and Chen-736 recognizes the distinction between PTS and DTS (Prelim. Resp. 14–15), on the current record, these arguments do not rebut Petitioner’s mapping of Chen-736 to the claim language. Similarly, Patent Owner’s argument that Chen-736 teaches a DTS for all picture signals, including the base viewpoints and non-base viewpoints (Prelim. Resp. 16), does not rebut Petitioner’s mapping of Chen-736’s enhancement-layer DTS to the claim language. At this stage, on the current record we determine Petitioner has sufficiently shown that Chen-736 teaches or reasonably suggests this claim element.” slip op. at 12

See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art). Petitioner’s proposed definition appears overly restrictive, as it requires a graduate degree in a narrow field of engineering or equivalent experience. We find that a bachelor’s degree with the accompanying experience proposed by Patent Owner more closely aligns with the prior art of record and the ’659 patent. We note, however, there is some overlap in the proposed levels of ordinary skill in the art because Patent Owner’s proposal includes “at least” a bachelor’s degree, which would encompass Petitioner’s master’s degree as well.

      “We disagree with Patent Owner’s claim construction. By using the word “or,” the plain and ordinary meaning of “prone, kneeling, or standing” is that only one must be satisfied to meet the claim. See, e.g., SkinMedica, Inc. v. Histogen Inc., 727 F.3d 1187, 1199 (Fed. Cir. 2013) (“The disjunctive ‘or’ plainly designates that a series describes alternatives.”). Furthermore, and although claims are read in light of the specification, limitations in a specification are not read into a claim. In re van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). Even if the Specification describes embodiments in which the user can begin in a prone position and then transition to a kneeling or standing position, as Patent Owner points out (see Prelim. Resp. 20), the claim does not recite the term “transitioning,” and we do not read the terms “each of” or “substantially flat surface” into this claim limitation. For example, the claim does not recite a “substantially flat” top surface and Patent Owner’s attempt to infer this structure into the claim is not supported under the law. See id. at 29–30.

Prelim. Resp. 19–21 (citing Ex. 1001, Abstr., 4:13–17, 4:33–40; Ex. 2006 ¶ 18). We do not agree with Patent’s Owner proposed construction because even if the Specification discloses that all three positions are possible, that is not what the plain language of the claim requires. Claim 1 recites “or,” which means that a user can be disposed on the top surface of the flotation device in any one of the three positions. See, e.g., SkinMedica, Inc. v. Histogen Inc., 727 F.3d 1187, 1199 (Fed. Cir. 2013) (“The disjunctive ‘or’ plainly designates that a series describes alternatives.”).
