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

      “partes review. See 35 U.S.C. § 314; 37 C.F.R. § 42.4(a). Under 35 U.S.C. § 314(a), we may not authorize an inter partes review unless the information in the petition and the preliminary response “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons stated below, we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one claim. We therefore institute inter partes review as to all of the challenged claims of the ’655 patent and all of the asserted grounds of unpatentability in the Petition.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “III. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art: would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent, and two years of work experience with network devices and communication technologies. EX1003, ¶¶17–19. Additional education might compensate for less experience, and vice versa. Pet. 4 (citing Ex. 1003 ¶¶ 17–19).” slip op. at 6

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for petitioner

      “The ’655 patent Specification states that: The topology data table 21 of the online server 20 is mainly recorded with a link data 49 between each of the P2P devices 41– 46 within the P2P device community. The link data 49 refers to the connection relationship between the P2P devices 41–46, which includes, but is not limited to, the connection structure, connection data and/or locations of connection. Ex. 1001, 4:51–57. On this preliminary record, we agree with Petitioner that the term “link data” is a “connection relationship between the P2P devices.” This meaning is consistent with the ordinary meaning of the term within the context of the claim, that is, “link data” means data on the links (connections) between each of the P2P devices, where the Specification provides a more fulsome meaning that the term includes, at least, “the connection structure, connection data and/or locations of connection.” See id. at 4:55–57. We invite the parties to provide additional briefing on the construction of this term during trial.” slip op. at 8

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “Lee discloses that the P2P overlay is generated with the overlay generation unit 220 that generates the P2P overlay by analyzing information regarding “the corresponding application service, the peer, and the network,” where the network information “may include a network topology, a maximum bandwidth, a current network usage, [and] a transmission delay time, and the like.” Ex. 1005 ¶ 54. We determine that this disclosure provides support for Mr. Lett’s testimony that “Lee describes techniques for changing an overlay in response to changing network characteristics,” which could be beneficial. Ex. 1003 ¶ 48. Accordingly, on this preliminary record, we find this evidence is sufficient to support a rationale to combine Schwan and Lee. See KSR, 550 U.S. at 401 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious.”).” slip op. at 13
