      “Also, to the extent Masaba relies on extrinsic expert testimony, we note that Masaba’s expert cites absolutely no support for his understanding of the claims, much less explains why we should adopt his understanding over the plain and ordinary meaning of “conveying aggregate” and “moving aggregate.” See Ex. 2004 ¶ 34. Absent supporting citations, such extrinsic testimony is entitled to little, if any, weight.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “We disagree that Dr. Durham does not possess the necessary level of skill in the art to qualify as an expert in this case. Looking at the specification of the ’689 patent and the prior art of record, we think Masaba sets the bar too high. We acknowledge that one of ordinary skill in the art should have some education and/or experience in the mechanical art of conveying aggregate materials, but we do not think opining on the ’689 patent and asserted prior art necessarily requires that person to have the amount of education and experience that Masaba advocates. The ’689 patent relates generally to an “aggregate transferring system for receiving aggregate from a vehicle and elevating the aggregate to a higher vertical level for deposit into, for example, a silo.” Ex. 1001, 1:15– 18. And, as described in the ’689 patent and discussed later, the transferring system is an assembly of known types of conveyors, such as a belly-dump truck conveyor, a bucket elevator, and an articulated belt conveyor, for transferring the aggregate horizontally and vertically from a belly-dump truck to the discharge point, such as a silo. Without doubt, Dr. Durham has enough education and experience to reliably opine on the combination of known parts.” slip op. at 8

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction needed

      “We reject this argument for several reasons. First, nowhere does the plain language of the claims specify how the aggregate is conveyed or moved from the conveyor extension assembly’s inlet to its outlet, be it passively by means of gravity or actively by means of a conveyor belt. Instead, the claims simply use those verbs according to their plain and ordinary meaning, which is “to transfer or deliver” or “to cause to go or pass” from one place to another. See Ex. 3001, 253 (defining “convey”), 760 (defining “move”).10 Second, the specification of the ’689 patent similarly uses these terms in a plain and ordinary sense, without ever attributing to them some sort of special meaning. See, e.g., Ex. 1001, 4:9–12 (“The apparatus 10 is suitable for performing the transfer of aggregate from 10 We reference the original pagination of the dictionary in which these definitions appear. one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate.”). The ’689 patent specification also makes clear that active conveyance of the aggregate is an option and not a requirement of the claimed invention, stating that the conveyor extension assembly “may further include a conveyor belt 150.” Ex. 1001, 10:60–66 (emphasis added). Limiting claim elements 1[h] and 1[i] to a device “for actively conveying” or “for actively moving aggregate” would improperly import limitations from the specification into the claims. Thus, based on the intrinsic evidence, we determine that claim elements 1h and 1k are properly construed to encompass passive and/or active movement of the aggregate via the conveyor extension assembly.” slip op. at 20

See id. at 24–25. Only in disputing Solaris’s Ground 3 does Masaba advocate that the claim term “trailer structure” should be construed under § 112(f), and then only in conjunction with dependent claims 3 and 21. See PO Resp. 58. As such, we address Masaba’s proposed construction in our analysis of Ground 3. We now turn to Solaris’s grounds of unpatentability.” slip op. at 12

      “on embodiments of Yeh with concentric sand screens having nine shunt tubes (six transport tubes and three packing tubes) (Yeh Figures 4A–B) and eccentric sand screens with four shunt tubes (two transport tubes and two packing tubes) (Yeh Figures 8A, 8C). See Pet. 32–37, 39, 41–43. Yet, Petitioner’s reasoning as to why “a higher-pressure shunt tube assembly necessitated greater wall thickness” rests on an unspoken one to one comparison between the shunt tubes of the different systems. See id.; see also Ex. 1003 ¶¶ 291–297 (Petitioner’s declarant comparing possible transport tubes of different pressure regions without considering or addressing any difference in the number of transport tubes). However, the embodiments relied on by Petitioner have different numbers of shunt tubes, and thus the greater wall thickness does not appear to be “necessitated” in the way inferred by Petitioner. Further, Petitioner’s analysis would seem to be most appropriate when comparing two concentric sand screens for different pressure regions, or two eccentric sand screens for different pressure regions. relies on Yeh’s teachings related to a horizontal well bore of 5000 feet for the “concentric screen → crossover tool → eccentric screen” arrangement, as well as, for why the concentric screen needs to be rated for a high pressure. Pet. 32–37, 39, 41–43. Petitioner also refers to these features for why one of skill in the art would combine the teachings of Yeh and Yeh2. Id. at 32. However, on cross-examination, Petitioner’s declarant agreed that it is concentric sand screens having a 6x3 shunt tube design that would provide the noted benefits of being rated for a higher pressure and being more robust (as relied on in the Petition), as compared to eccentric sand screens. Ex. 2013, 42:20–43:8; Sur-reply 4–5. This also exposes another issue with Petitioner’s arguments. Though Petitioner identifies that one of skill in the art would be aware that material choice, wall thickness, and pipe diameter all impact burst pressure of a pipe (Pet. 42 (citing Ex. 1017, 24 (Equation (14))), the Petition essentially ignores the fact that the claims do not require a single pipe in isolation. The claims require two shunt tube assemblies, each surrounding a base pipe within a wellbore. It is uncontested that a wellbore provides a confined space for such a system and thus any change in wall thickness of one pipe can result in a significant impact in the function of the other pipes. We find the testimony of Petitioner’s declarant (see, e.g., Ex. 1003 ¶¶ 290–297) unpersuasive when discussing wall thickness because it focusses on basic considerations of a standalone pipe, without sufficient consideration of the claimed completion assembly with its required pipe and tube structure.

Petitioner does not provide a citation to Yeh or a citation to where the Petition relies on the same number of shunt tubes between concentric and eccentric screens. The deposition cited by Petitioner discusses Yeh at column 16, lines 26 through 35. However, the Petition does not cite or rely on these teachings of Yeh. Thus, we decline to consider this late argument.4 See 35 U.S.C. § 312(a)(3) (requiring the petition to identify “with particularity . . . the grounds on which the challenge to each claim is based, and the evidence that supports the grounds”); 37 C.F.R. § 42.104(b)(5).” slip op. at 18

      “Thus, we agree with Petitioner that the combination of Yeh and Yeh2 teaches determining the shunt tube system operating pressures associated with the distal end of the production zone, but also more generally, determining the operating pressures along the entire production zone. With this knowledge of the system operating pressures, Petitioner argues that one of skill in the art would have selected eccentric screens for the distal end of the production zone “at any point at which the slurry pressure dropped below the pressure capacity of the eccentric screen shunt tubes.” Pet. 66 (citing Ex. 1005, 30:16–20; Ex. 1003 ¶ 388). In other words, knowing that the pressure decreases as you approach the toe, Yeh’s low-pressure rated eccentric screens could be used from some point prior to and covering the toe. determined pressure.” PO Resp. 37–38. We disagree. As discussed above, the record supports Petitioner’s position that one of skill in the art would have “understood the need to determine the shunt tube system operating pressure throughout the horizontal wellbore.” Ex. 1003 ¶ 383; see also Pet. 64–65. We find convincing Petitioner’s argument that one of skill with this understanding of the system pressures would select a shunt tube system rated to not only address the distal end, but also to address the needs of the adjacent region, so long as the pressure rating supported such a selection. See Pet. 65–67; Ex. 1003 ¶¶ 385–388.” slip op. at 22

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “At this stage of the proceeding, we are persuaded that Petitioner has established a reasonable likelihood that a person of ordinary skill would have combined the teachings of Yerazunis and Fiore for the reasons arguments do not directly address the specific combination proposed by Petitioner nor the specific motivations provided by Petitioner. For example, as explained further below in our analysis of claim 1, the gun embodiment of Yerazunis does not stop recording video after a triggering event. See Ex. 1017, 17:50–59. Moreover, Fiore’s file-based approach would provide the benefits highlighted by Petitioner regardless of whether Yerazunis stops recording video after a triggering event or continues recording to the next event. Similarly, the argument that Fiore does not selectively write protect data does not address Petitioner’s combination, which relies on Yerazunis, not Fiore, for teaching selectively write protecting data. Patent Owner’s argument also does not explain why a person of ordinary skill would not use Fiore’s file-based approach in implementing Yerazunis’s video recording device. Finally, Patent Owner’s argument that Fiore does not store individual segments within the circular buffer does not address Petitioner’s reliance on Yerazunis’s gun implementation in which individual segments are stored in the circular buffer. See Pet. 28 (“Yerazunis does disclose that in a gun camera embodiment, ‘the head pointer 104 and the tail pointer 102 . . . defining the area(s) of the circular buffer memory, are stored in a table to allow later retrieval of the video data pertaining to each firing of the gun.’” (quoting Ex. 1017, 17:50–56)); see also Pet. 30–32, 38–39.” slip op. at 22

      “of Yerazunis in combination with Fiore. On this record, Petitioner has demonstrated the similarities in the data recording systems of Yerazunis and Fiore. Petitioner asserts a reasonably sufficient basis for establishing the “specified frame data associated with [the] firing event” to be preserved as the disclosure of a designated segment that is write-protected. Based on the current record, we find Petitioner’s evidence more persuasive than Patent Owner’s assertion that Yerazunis preserves the entire buffer—not designated segments. Again, Petitioner admits Yerazunis does not expressly refer to “indexing write-protected segments as second files” but further establishes with sufficient basis that a person of ordinary skill in the art would understand the tagging features of Yerazunis aligns with the concept of indexing. Further, Petitioner shows that eventually it will be necessitated to locate or retrieve the data, providing further motivation for indexing, which is not only disclosed in Fiore, but demonstrated as well known in the art. See Pet. 28–29. Petitioner demonstrates the combination of Fiore and thus, on the current record, we are not persuaded by Patent Owner’s argument that Yerazunis only preserves post-recording data. Patent Owner further does not provide sufficient basis of reasoning that the “memory designation scheme” of Yerazunis which uses “unused block[s] of memory” establishes there is no write-protected segment. In consideration of the above, we are persuaded for purposes of this Decision that Petitioner has cited sufficient evidence to demonstrate that person of ordinary skill in the art would have had a rational basis to combine the teachings of Yerazunis and Fiore and this combination teaches these limitations of element 4.” slip op. at 33

See Williamson, 792 F.3d at 1350 (identifying words such as “mechanism,” “element,” “device,” and others as verbal constructs that do not connote sufficiently definite structures). Indeed, the Specification discloses all of the “components” recited in claims 1, 8, and 15, including the “comparing component,” can be “implemented as a computer having tangible computer-readable media for carrying or having computer-executable instructions or data structures stored thereon.” Ex. 1001, 5:35–43. Thus, like the word “module,” a recognized nonce word, each of the recited “components” is nothing more than “a generic description for software or hardware that performs a specified function” and their recitation “operate[s] as a substitute for ‘means’ in the context of § 112, para. 6.” Williamson, 792 F.3d at 1350. Accordingly, we construe the “comparing component” limitation recited in claims 1, 8, and 15 as a meansplus-function limitation whose function is “generating a comparison signal.”2” slip op. at 14

      “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)). 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.

      “Finally, we are reminded that “a sufficient description of the genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350. “[F]unctional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. Here, however, the challenged claims are directed to methods using a wide range of different types of compounds purported to be “IL-15/IL-15R inhibitors” that are not part of a known or readily identifiable class, do not target the same biological pathway, do not have any common structural features, and do not appear to always function as inhibitors. See Ex. 1018, Abstr., 1575–77, 1579; Ex. 1046, 189:4–19, 191:15–192:15, 193:18–196:22, 198:21–199:21, 197:12–198:19, 200:1–8, 207:11–14, 203:3–10, 207:15–21, 236:12–24; Ex. 1047 ¶¶ 19–23, 56, 63–64, 80–85.

      “598 U.S. at 610. A “specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. 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
