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.

Patent Owner next contends that Kido does not disclose a first payout that is “for the spin of the roulette wheel.” Prelim. Resp. 29. Patent Owner’s argument is premised on the cumulative nature of Kido’s Prog bonus – it builds with every spin of the roulette wheel until won. Id. (“Each time the wheel is spun, 0.5% of the amount wagered is added to the progressive jackpot, and thus, the jackpot’s value reflects multiple spins of the roulette wheel.”). Thus, according to Patent Owner, the value of the jackpot is determined using multiple spins of the roulette wheel and is not “for a spin of the roulette wheel” as claimed.” Id. at 30. The claims, however, only require a first payout that is higher than a second payout. Nothing prohibits the higher payout from accumulating from prior spins of the roulette wheel because, when it is actually won, it will be for that last spin of the roulette wheel. Ex. 1005, 8:35–36 (“indicating that the first player is to be paid at the first payout for the spin of the roulette wheel”). Regardless of how Kido’s Prog bonus accumulated, it is paid for a spin of the roulette wheel – at that juncture Kido discloses each claim element. Anticipation occurs when a prior art reference discloses every element of a patent claim at a point in time, as Kido does with a single spin of the roulette wheel that pays the Prog bonus. As persuasively explained by Petitioner, “the steps of Figure 12 (including A13) occur within a single round of roulette, for a single spin of the roulette wheel, until the routine ‘returns to the step of A1 and is transited to a next game.’” Pet. 39 (quoting Ex. 1007 ¶ 233).” slip op. at 13

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

“proceeding, we disagree with Patent Owner’s assertion that the applicable rules and guidance require Petitioner to do more. In pertinent part, Rule 42.104(b) requires that a petition set forth: “(3) How the challenged claim is to be construed. . . . [and] (4) How the construed claim is unpatentable.” 37 C.F.R. §§ 42.104(b)(3), (4). The Consolidated Trial Practice Guide8 explains: If a petitioner believes that a claim term requires an express construction, the petitioner must include a statement identifying a proposed construction of the particular term and where the intrinsic and/or extrinsic evidence supports that meaning. On the 8 Consolidated Trial Practice Guide (November 2019), available at https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf, hereinafter as “CTPG.” other hand, a petitioner may include a statement that the claim terms require no express construction. CTPG 44. Under the circumstances of this case, the applicable rule and our Practice Guide permit Petitioner to rely on the plain and ordinary meaning of these claim terms. After all, as Petitioner points out, that is the construction that Patent Owner proposes for these terms in the district court case.9 See Ex. 1029, 2. Moreover, Petitioner contends that even under Petitioner’s proposed construction from the district court case, the prior art teaches these claim limitations. Pet. 8, 15–17 (explaining how Dongare allegedly teaches implementation “in physical circuits, without software intervention”), 49–52 (similar arguments for Khawand and Rosenthal), 74–75 (similar arguments for Ohkawa). Because, as discussed below, we agree with Petitioner that, on the current record, Dongare teaches these claim limitations even under the construction that Petitioner proposes in the district court, we need not expressly construe these claim terms. 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)). If Patent Owner believes these terms should be construed differently, Patent Owner may propose a construction and identify where the intrinsic and/or extrinsic evidence supports its construction.

“According to Petitioner, “no express constructions are required in this proceeding.” Pet. 4. Patent Owner “agrees that the terms of the ’728 Patent have their plain and ordinary meaning.” Prelim. Resp. 7. However, Patent Owner contends that Petitioner construes the claim language “during the driving period” to mean “throughout the driving period.” Id. at 10 (claim language found in claims 1, 13, 24, and 25). Patent Owner contends Petitioner consistently uses the term “during” rather than “throughout” in the analysis of the challenged claims. Id. Patent Owner does not provide support for any specific construction or explain why any claim construction would be necessary for resolution of this proceeding. Based on the current record, we determine the differentiation asserted by Patent Owner between the use of “during” and “throughout” does not require express interpretation as the terms “during” and “throughout” are synonymous.8 Upon review of the record, we determine that no claim terms require express construction for purposes of this Decision.

“Based on our review of the preliminary record, we conclude Petitioner has explained with supporting evidence how the combination of Callopy, Curry, and Thompson teaches or suggests claim 1, sufficiently to justify institution of review. That is, Petitioner explains how a person of ordinary skill in the art would have been motivated to supplement the risk assessment capabilities of Callopy-Curry with the well-known accident detection techniques of Thompson’s WreckWatch application to reduce vehicular accidents and casualties. For the purposes of institution, Petitioner has articulated a reasoned explanation why a POSITA would have been motivated to modify Callopy’s wireless device with Curry’s calculation techniques, and Thompson’s accident detection capabilities. The Petitioner has explained in detail that Curry contemplates the need for multi-modal operation for nuanced driving conditions, and that the incorporation of Callopy would be a natural modification that aligns with standard insurance evaluation methods. Petitioner further explains the implementation of Curry’s scoring system, which is capable of logging data and processing safety statistics, in combination with Callopy’s system leads to enhanced sensor-based driving evaluation in the determination of a driver’s risk profile for insurance purposes. Petitioner further explains in detail how Thompson’s implementation further provides motivation for Curry’s initiatives to “reduce traffic-related fatalities and injuries” and that a POSITA would seek the well-known accident detection technique of Thompson to achieve this. Petitioner identifies that the combination of Callopy, Curry, and Thompson not only can be achieved without any changes to underlying hardware, but also provides the functionality of recording sensor data relating to driving, calculating driving safety statistics, and detecting driving-related incidents. Moreover, as discussed, Petitioner has provided citations to the references along with corroborating testimony from Dr. Michalson that support its arguments for why and how a POSITA would have combined the prior art disclosures with a reasonable expectation of success.

“arguments and evidence for purposes of institution that would support determining that a person of ordinary skill in the would have been motivated to combine the teachings of Shin and Aoyama. As one example, Amazon contends that the proposed combination is merely the addition of one known element (i.e., “Aoyama’s natural language processing and information retrieval”) to another known element (i.e., “Shin’s voice processing and response device”) to obtain predictable results (i.e., “identifying a user’s intent and providing information responsive to such intent”). Pet. 19–20 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 83). As another example, Amazon contends the proposed combination also represents the addition of one known element (i.e., “Aoyama’s word replacement” feature) to another known element (i.e., “Shin’s distance-based content abbreviation/simplification”) to obtain predictable results (i.e., “using word replacement to simply content for distant users”). Id. at 25–26 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 100). Amazon also presents sufficient arguments and evidence for purposes of institution that would support determining there is a reasonable expectation of success in making the proposed combination. Id. at 20 (citing Ex. 1002 ¶ 84), 27–28 (citing Ex. 1002 ¶ 102; Ex. 1011 ¶¶ 97, 98 Fig. 7). To the extent SoundClear argues that Amazon is required to identify a problem a person of ordinary skill in the art would have sought to solve when combining the teachings of Shin and Aoyama, we do not agree. See Prelim. Resp. 31–32. This line of argument runs contrary to the principles of law articulated in KSR. In KSR, the Supreme Court emphasized “an expansive and flexible approach” to an obviousness evaluation. KSR, 550 U.S. at 415; see also Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1363 (Fed. Cir. 2018) (“KSR did not impose a rigid requirement to identify . . . a problem to be solved in the art . . . .”).

“Based on the preliminary record, we discern no deficiency in Amazon’s characterizations of Shin, Aoyama, or the general background knowledge in the art. In addition, for purposes of institution, we are persuaded by Dr. Stern’s testimony concerning the relevant disclosures in Shin and Aoyama. At this stage of the proceeding, SoundClear argues that Shin does not teach limitations 1[b]—“a voice classifying unit configured 1[b][i] to calculate a distance between the user and the output-content control device by a proximity sensor 1[b][ii] to classify the voice into either a first voice or a second voice based on the calculated distance.” See Prelim.

Limitations 1[b]—“a voice classifying unit configured to 1[b][i] calculate a distance between the user and the output-content control device by a proximity sensor to 1[b][ii] classify the voice into either a first voice or a second voice based on the calculated distance” In the Preliminary Response, SoundClear contends that Shin fails to teach voice classification because “Shin is incapable of distinguishing [between] multiple voices.” Prelim. Resp. 21. More specifically, SoundClear argues that Shin cannot teach classifying a voice into a first voice or second voice because “Shin never refers to a ‘first user’ or ‘second user’ or ‘multiple users.’” Id. (citing Ex. 1003 generally); see also id. at 26– 27 (arguing that Amazon misstates the record because Shin never discloses a “first voice” nor a “second voice”). Instead, SoundClear asserts that Shin only contemplates a single user (i.e., user 10) when calculating the distance between the user and an electronic device (e.g., Shin’s electronic device 100). Id. at 21–22 (citing Ex. 1003 ¶¶ 37, 38). Based on the preliminary record, Amazon presents sufficient evidence that would support a finding that Shin teaches “a voice classifying unit configured to calculate a distance between the user and the output-content control device by a proximity sensor to classify the voice into either a first voice or a second voice based on the calculated distance.” Pet. 10–14. Shin discloses that “processor 120 may determine an output scheme of corresponding content based on a distance between a user and the electronic device 101.” Ex. 1003 ¶ 53. Shin’s processor 120 accomplishes this distance calculation by using distance detection module 180, which may include various sensors, such as a proximity sensor. Id. ¶ 66; see also id. ¶ 153 (disclosing an embodiment where electronic device 901 includes sensor module 940, which, in turn, includes proximity sensor 940G). Shin’s Table 3 illustrates how the distance between the user and electronic device 101 determines the output scheme. Id. ¶ 86, Table 3. For instance, Shin’s Table 3 illustrates classifying the user’s voice input as a “first voice” when the distance between the user and electronic device 101 is between 1 to 2 meters, and classifying the user’s voice input as a “second voice” when the distance between the user and electronic device 101 is less than 1 meter.
