      “At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim. Resp. 32 (citing Pet. 16; Ex. 1004 ¶ 72) (first alteration added). At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments regarding the microprocessor. Although Patent Owner does not bear the burden to show patentability, we observe that Patent Owner does not suggest that there is another component in Olson’s external charging device that might perform the admittedly-disclosed power calculation. See Prelim. Resp. 32–33. Dr. Woods testifies that microprocessor 212 receives the measured current and the input voltage of the charging device, and, from those values, calculates power in. See Ex. 1003 ¶¶ 43–44 (citing, inter alia, Ex. 1004 ¶¶ 71–78, Fig. 14); see also Ex. 1004 ¶ 74, Fig. 14 (Olson stating that “[c]urrent measured by current measure block 226 is used in the calculation of power in along with the voltage of batteries 160,” and Figure 14 depicting the signal from measure block 226 as an input to microprocessor 212).

      “Petitioner contends that the challenged claims do not need construction to demonstrate unpatentability. Pet. 14. Petitioner, however, notes that the parties in the ITC proceeding identified above dispute the meaning of several claim terms. Id. (citing Ex. 1026). Petitioner specifically notes that “the parties dispute what is required of independent claims 1, 5, and 16 to ‘determin[e] how many pixels’ to filter in each block.” Id. (citing Ex. 1026, 6–7). Petitioner argues that “ITC Respondent Lenovo mathematical basis (no relationship) with the pixel values of the pixels in said neighboring block’” (id. (citing Ex. 1026, 6–7)), but Patent Owner “contends that no construction is necessary,” “and the ‘plain meaning’ does not foreclose some ‘mathematical basis’ existing as long as separate decision values are calculated for each block” (id. (citing Ex. 1027, 14–19)). Petitioner indicates that Ground 1 adopts Patent Owner’s broader construction from the ITC proceeding and Ground 2 adopts Lenovo’s narrower construction. Id. at 14–15. Patent Owner argues that “none of the asserted grounds disclose or render obvious the Challenged Claims under the plain meaning of the claims (which is [Patent Owner’s] proposed construction) or under Lenovo’s narrower proposed construction.” Prelim. Resp. 29. On the present record, we do not discern a need to construe explicitly any claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “Furthermore, we are not persuaded that modifying Aksu in view of Gonzalez in the manner proposed by Petitioner overcomes this problem. As noted above, Petitioner asserts that, in the proposed combination, one of ordinary skill in the art “would have understood that the Laplacian’s output would be compared directly to a threshold based on β—just like Aksu’s difference calculations—to determine how many pixels to filter.” Pet. 60 (citing Ex. 1019, 13:15–19; Ex. 1003 ¶¶ 406–410). We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed.

However, at this stage and absent argument to the contrary by the parties, we discern no material difference between the parties’ definitions. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

As to the second part, we understand Patent Owner to be referring to the purported benefit of linear control, and we determine that Patent Owner has not explained adequately why such a benefit should be read into the claim term “substantially different,” particularly where the quoted Specification support does not explicitly mention linear regulation.7 See Ex. 1001, 21:61–63 (“The induced voltage 7 To the extent that Patent Owner relies on its declarant’s testimony as an explanation of Patent Owner’s claim construction position, we remind Patent Owner about the prohibition on incorporation by reference.

Specifically, limitation 1.7 requires a driving circuit that is “configured and operable to produce said oscillating driving voltage at a transmission frequency” that is “substantially different” from the inductive couple’s resonant frequency. Ex. 1001, 28:43–46. In future briefing, the parties’ arguments regarding the prior art references should focus on that recited structure, i.e., a circuit that is configured and operable to produce the recited frequency.” slip op. at 21

      “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”).

      “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.

      “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.

Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986); Orthopedic Equip. Co. v. U.S., 702 F.2d 1005, 1011 (Fed. Cir. 1983).

Cir. 1992), it is incumbent on a petitioner, in advancing a permissible theory of obviousness, to explain why a skilled artisan would recognize to pick and choose certain aspects of a reference and combine them with other aspects of the reference, particularly so where the reference itself does not suggest such combination.

Petitioner disagrees, arguing that the Petition cites “voluminous disclosure” from Rousselle identifying the benefits of a central lock. Reply 18 (citing Pet. 35). We agree with Petitioner. The Petition provides several rationales, supported by Dr. Stein’s testimony, for making the alternative modification. Pet. 35–37. For instance, Petitioner argues that one of ordinary skill in the art would have been motivated to make this modification because Rousselle discloses the benefits of a central lock over Tsai’s individual leg locking system, such as making the canopy easier and more convenient for a single user to operate. Id. at 35–36 (citing Ex. 1002 ¶¶ 102–103; Ex. 1003, 3:38–47; Ex. 1005, 4:29–5:5, 8:5–33, Figs. 1, 2, 18, 19). Petitioner also argues that the proposed modification is the simple addition of one known element to another known element to obtain predictable results and uses a known technique to improve a similar device and yield predictable results. Id. at 36–37 (citing Ex. 1002 ¶¶ 105–107; KSR, 550 U.S. at 417). We have reviewed Petitioner’s arguments and evidence and find the reasons to combine persuasive. In sum, we determine that Petitioner’s proposed reasons to combine Rousselle and Tsai in accordance with the alternative modification are realistic, have rational underpinning, and are supported by expert testimony, which we find persuasive and credit.

      “We agree with Petitioner that Tsai’s disclosure of pulling the poles or legs apart to unfold the frame does not disparage central activation to the extent of discouraging one of ordinary skill in the art from investigating or considering Rousselle’s central lock in connection with Tsai’s shelter frame. See DePuy Spine, 567 F.3d at 1327 (holding a reference does not teach away “if it merely expresses a general preference for an alternative invention but does not ‘criticize, discredit, or otherwise discourage’ investigation into the manually pulling the four poles 1 outwardly.” Ex. 1005, 10:28–29 (emphasis added). As such, Tsai “merely expresses a general preference” for this technique (see DePuy Spine, 567 F.3d at 1327) and does not specifically require it. We agree with Petitioner that Tsai’s general preference for this technique does not teach away from any other method for unfolding the frame. Furthermore, Tsai’s statement that the shelter frame of Figures 16 and 17 is “somewhat difficult to unfold in that an extra person is sometimes needed to push the center strut C upwardly to its completely extended position” (Ex. 1005, 2:19–22) does not disparage all other center lock configurations, in particular the configuration taught by Rousselle. As Petitioner points out, Rousselle discloses that its collapsible shelter/tent with the central lock arrangement can be erected by a single person. Ex. 1003, 13:59–65. So, instead of requiring “an extra person,” the shelter frame of the combination of Tsai and Rousselle could be erected by a single person. Similarly, Tsai’s statement that the shelter frame of Figures 16 and 17 reduces headroom in the tent (Ex. 1005, 2:17–19) does not disparage all other center lock configurations. We agree with Petitioner that the inner units of both Rousselle and Tsai’s Figure 1 embodiment are different than the inner units shown in Figures 16 and 17, which are large scissors-type linkages located well below the canopy’s roof supported by center strut C. See Reply 11. In contrast, Rousselle discloses shelter/tent 10 in which collapsible frame 100 supports sheet-material cover 200. Ex. 1003, 6:30–32; Fig. 1(A). Unlike the shelter frame of Tsai’s Figures 16 and 17, Rousselle’s frame does not include an upwardly extending center strut propping up the sheet-material cover. Instead, sheet-material cover 200 rests directly on frame in which canopy supporting rods 3 (i.e., the “inner units”) form a canopy support for supporting the canopy material. Ex. 1005, 4:11–25, 7:15–20. Accordingly, neither Rousselle’s or Tsai’s frames present the headroom issue that Tsai identifies with respect to the prior art shelter frame of Figures 16 and 17.” slip op. at 27

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.
