“been obvious over the 1946 Cyclopedia and Wong. Weighing the parties’ arguments and evidence, we find Petitioner provides sufficient rational underpinning for its assertion that it would have been obvious in view of Wong to implement a cross-wise extending beam to reinforce the 1946 Cyclopedia’s NSC ore car’s end slope sheet. Pet. 52–53; Prelim. Resp. 28– 30. In response to Petitioner’s assertion that “[t]he upper, outboard end of [Wong’s slope sheet 26] is reinforced by a cross-wise, L-shaped beam positioned under the slope sheet,” Patent Owner argues that “Wong does not provide reinforcement, but simply shows two sheets being connected for lading containment and load transfer.” Pet. 52; Prelim. Resp. 29. At this stage, we find Petitioner has the better position. Although we agree with Patent Owner that Wong shows two sheets connected to one another, that does not negate Petitioner’s correct observation that Wong shows an upper end of its end slope sheet 26 resting on an L-shaped structure, which apparently would reinforce end slope sheet. Pet. 52; Ex. 1003 ¶ 56. reason to look to Wong in the first place,” we again find that Petitioner has the better position at this stage. Prelim. Resp. 29. For example, Wong’s disclosure of “hopper railcar 10” (Ex. 1006, 3:6–9) and the 1946 Cyclopedia’s disclosure of “Freight Cars: Hopper Ore” (Ex. 1004, 27–28; Ex. 1054, 27–28) support Petitioner’s position that “Wong and the 1946 Cyclopedia are in the same field.” Pet. 52; see also id. at 76 (“Wong discloses a rail road hopper car (‘hopper railcar’ 10)”), 18–19 (“The ore-car section of the 1946 Cyclopedia—entitled ‘Freight Cars: Hopper Ore’— contains drawings and a photograph of an ore car manufactured by Patent Owner NSC.”); Ex. 1003 ¶ 56 (“Wong and the 1946 Cyclopedia are in the same field of hopper railcars”) (citing Ex. 1004, 27–28; Ex. 1006, code [57]).

“to further support the upper, outboard end of the slope sheet with a crosswise, L-shaped beam as in Wong,” and one of ordinary skill in the art would have been motivated to do so, because of “the benefits of reinforcing the slope sheet at its upper end, where its connection with another structure creates a stress concentration.” Pet. 63 (citing Ex. 1003 ¶ 108).

“A. Legal Standards — Petitioner’s Burden “In an [inter partes review], 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.

Thus, we apply the pre-AIA version of § 103. grounds for the challenge to each claim”)). This burden of persuasion never shifts to the patent owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). B. Legal Standards — Obviousness A patent claim is unpatentable under 35 U.S.C. § 103(a) 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 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 ordinary skill in the art; and (4) objective evidence of nonobviousness, if made available in the record, which has not happened here.

“(iii) Analysis Based on the present record, we determine Petitioner’s contentions regarding the third step of claim 1 are supported sufficiently by the cited disclosures in Weese and Dr. Peterson’s testimony to justify institution of review. In particular, Weese describes obtaining a plurality of second images of the patient’s internal organs (i.e., PET image I0 in Fig. 1, and PET image I10 in Fig. 3) using a second imaging technique (i.e., PET). See Ex. 1005, Figs. 1, 3, and 6, ¶¶ 47–49, 58–59, 72. In particular, PET image I0 in Figure 1 may be a reconstructed “volume image[]” composed of a plurality of “quasi two-dimensional” “slice images” that, when combined, represent a three-dimensional region inside the patient. Id. ¶¶ 48, 58, 61; see also Pet. 56–57. PET image I10 in Figure 3 may be a similarly reconstructed volume image composed of a plurality of slice images.4 See 4 We do not rely here on Petitioner’s alternative theory that Weese discloses a “plurality” of second images because PET images I0 and I10 are “superposed” images encompassing “several states of motion.” Pet. 58. Ex. 1005 ¶¶ 61, 83–84. Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Also, it appears that PET images I0 and I10 are obtained while also obtaining second movement measurements of the patient’s internal organs using a second sensor system (i.e., motion acquisition unit 12 and motion sensor 15 / S1) which is independent from the PET imaging technique. See Ex. 1005, Figs. 1 and 6, ¶ 65 (“[T]he respiratory motion is determined during the acquisition of the PET projections P1 by means of a respiratory motion sensor provided on the patient and therefrom the frequency function f(r) or, more generally, a state of motion function F1 is derived for the construction of the motion model M2.”). Furthermore, Weese describes how frequency function f(r) is utilized to facilitate image comparison between CT and PET images at common motion states. See id. ¶¶ 31, 49–51, 70–71, 75–77, 79–80, 83; see also Ex. 1003 ¶¶ 214–216 (Dr. Peterson’s supporting testimony). Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Patent Owner’s two opposing arguments are unavailing, based on the present preliminary record. First, Petitioner relies on reconstructed PET images I0 and I10 as satisfying the “plurality of second images” recited in claim 1, not PET projections P1 from which PET images I0 and I10 are derived. See, e.g., Pet. 56, 58 (“I0 and I10 disclose and render obvious a ‘plurality of second images’ in two ways” — “I0 and I10 may be ‘volume images’ formed using ‘known’ techniques,” and “I0 and I10 are ‘superposed’ PET images encompassing ‘several states of motion,’ which” slip op. at 18

“Pursuant to 35 U.S.C. § 324(a), the Director may not authorize a post-grant review unless the information in the petition, if unrebutted, “would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” See 37 C.F.R. § 42.4(a) (“The Board institutes the trial on behalf of the Director.”).

“ordinary skill in the art would have had “an educational background of, or practical experience equivalent to, a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent training, and approximately three years of experience with electronic payment systems, vending machine technologies, or distributed network systems,” where “[l]ack of work experience can be remedied by additional education, and vice versa.” Pet. 20 (citing Ex. 1003 ¶¶ 20–26). Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on the record presented, including our review of the ’423 patent and the types of problems and solutions described in the ’423 patent and cited 2 Petitioner states that it “takes no position on the proper priority date for the [c]hallenged [c]laims” and “uses the earliest possible priority date claimed, December 18, 2013,” for purposes of its asserted grounds. Pet. 14. prior art, we agree with Petitioner’s definition and apply it for purposes of this Decision. See, e.g., Ex. 1001, 1:42–2:21 (stating that “[t]he present application relates to the field of payment processing systems” and describing the functionality of payment accepting units in the “Background” section).” slip op. at 7

“B. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.200(b). Petitioner states that, “for purposes of [its] Petition, the Board need not construe any claim terms to resolve the parties’ disputes, and the claims should be given their ordinary and customary meaning.” Pet. 20. Patent Owner agrees that “[n]o constructions are necessary” to decide the issues disputed by the parties. Prelim. Resp. 2–3. We conclude that no express interpretation of any claim term is necessary to determine whether to institute a post-grant review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)).” slip op. at 8
- PTAB / AIA Trials › §315(e) estoppelNot reached
“For the reasons explained below, we conclude, on the merits and based on the current record, that Petitioner has shown that it is more likely than not that claim 1 is unpatentable as claiming patent-ineligible subject matter under 35 U.S.C. § 101. See Pet. 77–84. Accordingly, we need not determine at this time whether collateral estoppel applies based on the Board’s decision in PGR2021-00093. The parties, however, should address the issue in their papers during trial, with citations to relevant authority. In particular, the parties are encouraged to address (1) how the collateral estoppel requirement that the issue be “identical to one decided in the first action” applies in the context of an asserted ground under 35 U.S.C. § 101, and (2) the parties’ apparent disagreement as to whether collateral estoppel may be applied in such circumstances on a “limitation-by-limitation basis.” See Pet. 72, 75 (quoting Google LLC v. Hammond Dev. Int’l, Inc., 54 F.4th 1377, 1381 (Fed. Cir. 2022)); Prelim. Resp. 20–21; see also Kroy IP Holdings, LLC v. Groupon, Inc., – F.4th –, No. 2023-1359, 2025 WL 2178321, at *4 (Fed. Cir. Aug. 1, 2025) (Dyk, J., dissenting) (“In subsequent Board proceedings, it is well established that collateral estoppel applies to claims adjudicated by the Board to be unpatentable and also to ‘related claims that present identical issues of patentability,’ i.e., patentably indistinct claims. . . . ‘It is well established that patent claims need not be identical for collateral estoppel to apply.’” (citing MaxLinear, Inc. v.
