“At this juncture in the proceeding, and based on the current record, we do not agree with Patent Owner that “payout,” as claimed, should be limited to “the amount a player will win in relation to the amount wagered.” We recognize, as Patent Owner points out, that the examples provided in the Specification are listed in odds format. See id. at 2. The Specification, however, also states that “[a]ny suitable payouts can be used in some embodiments.” Ex. 1011, 5:18–21. This language suggests a broader interpretation of “payout” beyond just payout odds and we therefore decline to import the wager limitation into the claim term. Although the ’371 patent generally describes payouts in terms of odds, like 49:1, the intrinsic record lacks clear evidence necessary to limit the claims as Patent Owner proposes.” slip op. at 8

Patent Owner does not dispute this level of skill. See Prelim. Resp. 13–14 (“Evolution does not set forth an alternative level of skill for a person of ordinary skill in the art”). For purposes of this Decision, we adopt Petitioner’s proposal, which comports with the teachings of the ’371 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Based on the evidence before us, we find persuasive Petitioner’s contention that Kido’s accumulated jackpot paid when landing on a star mark reads on the claimed “a first selected position . . . to have an increased payout . . . greater than a first non-selected payout.” See Pet. 25–27, 30, 35, 36. As explained above, the current record does not support limiting the term “payout” to just the amount a player will win in relation to the amount wagered. As Petitioner notes, a payout that receives Kido’s accumulated Prog bonus payout is necessarily higher than a payout that does not receive the Prog bonus. Pet. 35–36 (“had the first selected position not been randomly selected, the player would only be eligible for the basic payout”). Further, Kido even describes its bonus routines and jackpots as payouts. Kido describes, for example, that “[w]hen the privilege unit 113 obtains the win information from the special game value award mark win determining unit 112, it awards, as a payout, the game value stored in the accumulated game value memory 117” and it describes the “jackpot (JP) amount” as “a special payout.” Ex. 1007 ¶¶ 119, 129.” slip op. at 14

“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. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the 1 Amendments to 35 U.S.C. § 103 enacted by the Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”) took effect in March 2013. The ’353 patent issued from an application filed in September 2004. See Ex. 1001, code (22). 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

“Kelly discloses that game processor 12 implements the functions of game unit 10 during a game process and includes several input and output functions (Ex. 1005, 9:15–18), including: The game processor controls the game apparatus by receiving inputs from a player, from other game apparatuses, from a server (described below), from a progressive bonus apparatus, and from other sources. The game processor also controls output signals to update the game process when appropriate. In addition, the game processor controls the redemption system of the present invention by calculating when prizes are awarded, calculating and updating prize lists and prize costs, and other functions, as described below. Ex. 1005, 9:18–27. As to the redemption system, Kelly discloses prize table 480 that is displayed to the operator. Ex. 1005, 34:64–65, Fig. 9a. In one embodiment, the operator can adjust prize characteristics for the game unit and any linked game units. Id. at 35:1–2. Kelly also discloses an alternative embodiment, however, in which selection of a specific prize from the table 480 can be based on random and/or statistical determination. Id. at 36:48–49. In this alternative embodiment, “random determination of whether a particular prize is to be awarded is also modified by statistical information to create a ‘best fit’ of prizes awarded according to the operator’s desired odds.” Id. at 36:63–66. awarded every 8,000 games, so if it is randomly determined that a third video console is to be awarded within, for example, the 3000th game, then a different prize, e.g., the next most valuable prize, can be awarded so that the desired odds are better met. Id. at 37:1–9. Thus, we find Petitioner has set forth sufficient evidence to show a reasonable likelihood that Kelly’s game processor can modify the variable parameters of the prizing structure to meet the mandated parameters of the desired odds, as called for in limitation [1.c.v].” slip op. at 23

“To remove Walker as prior art under §§ 102(a) and 102(e), Patent Owner must show either it reduced the invention to practice prior to Walker’s effective date, or that it invented prior to Walker’s effective date. In the case of the latter, Patent Owner must demonstrate conception prior to May 1, 2003, and reasonably continuous diligence throughout the entire critical period, which begins just prior to the Walker’s effective date and ends on the date of the invention’s actual or constructive reduction to practice. Patent Owner provides evidence purporting to show that it conceived of the invention prior to May 1, 2003. Patent Owner has not asserted that this evidence demonstrates actual reduction to practice, nor do we have sufficient evidence at this stage to make that determination. Further, Patent Owner’s earliest possible constructive reduction to practice (September 1, 2004) does not pre-date Walker’s effective date. Thus, at this stage, Patent Owner would need to show it invented prior to Walker’s effective date through evidence of conception and reasonable diligence to remove Walker as prior art. At this stage of the proceeding, without Patent Owner’s evidence of diligence, Patent Owner has not provided sufficient evidence to show that Petitioner fails to show a reasonable likelihood of prevailing in establishing that Walker is prior art. This issue of whether Walker is prior art to the ’164 patent will benefit from further development of the record during the trial proceeding.” slip op. at 31

“But the Detecting Limitations of claims 1, 19, and 20, merely require that a target be “detected.” The Detecting Limitations do not require that target detection be performed “aboard the reference UAV,” and claim 19 does not recite or require “machine learning.” Moreover, the Specification makes clear that the claims should not be limited to aspects of the disclosed embodiments, as Patent Owner proposes to do here. See, e.g., Ex. 1001, 2:56–59 (“The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims . . . .”) Patent Owner additionally fails to cite any lexicographic definition or clear and unambiguous disclaimer of claim scope sufficient to limit the claims in the manner it proposes.
