See Pet. 1. We determine that the preamble of claim 7 is not limiting because it does not recite essential steps or structure and is not necessary to give life, meaning, and vitality to the claim. See Shoes by Firebug LLC v. Stride Rite Children’s Group, LLC, 962 F.3d 1362, 1367 (Fed.

At least at this stage, there is no dispute between the parties as to whether Josiam or the ’595 patent are entitled to the claimed priority. See Prelim. Resp. 1 fn.1, 12 fn. 2.

“combination of the disclosures of Chen and Wu and articulates reasons why a skilled artisan would be motivated to combine the relevant teachings of Chen and Wu. See Pet. 42–85. This challenge to the patentability of the claims of the ’595 patent (Ground 2 of the Petition) is detailed and supported by the cited evidence. With regard to this ground and the asserted combination of art, Patent Owner argues that “[s]imilar to Grounds 1A and 1B, Chen and Wu do not show that ‘the bandwidth field of HE-SIG-A is used to obtain information of the unassigned resource unit’ as both the bandwidth field in HE-SIG-A and a subfield in HESIG-B need to be used for explicitly indicating the unassigned resource unit.” Prelim. Resp. 15. The quoted passage is limitation 7.5 and the “explicitly indicat[ing]” element is in limitation 7.7.16 See Ex. 1001, 54:3–4, 54:9–12; see also Pet. vii (showing claim 7 with limitations numbered and labeled). Thus, Patent Owner disputes the same limitations with a similar argument as for the earlier grounds in disputing the showing in the Petition for this ground. With regard to the disputed limitations, the Petition provides that, from a combination of the teachings and suggestions of Chen and Wu, a skilled artisan would understand that “the bandwidth field of HE-SIG-A indicates where in the overall bandwidth the non-allocated RU is located by defining the number of 20MHz channels and the arrangement and length of the HE-SIG-B content channels.” Pet. 60 (citing Ex. 1003 ¶ 178). The Declaration of Dr. Buehrer provides: 16 Limitation 7.7 recites: “the unassigned resource unit is explicitly indicated with the information of the unassigned resource unit based on the bandwidth field and the at least one subfield.” Ex. 1001, 54:9–12; Pet. vii (emphasis added). 178. Chen-Wu renders obvious using the bandwidth field of HE-SIG-A to obtain the information of the unassigned resource unit. As one example, a POSITA would have understood the Chen-Wu combination as rendering obvious that RU non-allocation information in HE-SIG-B indicates the location of a non-allocated RU within a 20MHz channel, while the bandwidth field of HE-SIG-A indicates where in the overall bandwidth the non-allocated RU is located by defining the number of 20MHz channels and the arrangement and length of the HE-SIG-B content channels. SAMSUNG-1008, [0101], [0098]; SAMSUNG-1009, [0036]; SAMSUNG-1010, 10. 179. Chen teaches that “RU allocation may be determined based at least in part on the PAID, channel bandwidth, and the HE-SIG-B.” SAMSUNG-1008, [0101], [0098]. I note that the Applicant did not dispute the Examiner’s finding that Chen teaches this limitation. See SAMSUNG- 1002, 68, 102 (citing SAMSUNG-1008, [0093], [0098], [0103], Fig. 14). 180. Moreover, Wu teaches “a fixed format common field in the HE-SIGB is defined for each operation bandwidth. Therefore, the length and format of the common field are predefined [based on the bandwidth]. In this approach, there is no [additional] indication needed in the HE-SIG-A.” SAMSUNG-1009, [0036]; SAMSUNG-1010, 10. As I explained above for [7.2] and [7.4], a POSITA would have understood Chen’s HE-SIG-A as including a bandwidth field that indicates the operation bandwidth of the PPDU. See [7.2], [7.4]. 181. For example, if the bandwidth field of HE-SIG-A indicates a PPDU bandwidth of 80 MHz, and the resource unit allocation field of the common field of HE-SIG-B indicates that the 20 MHz corresponding to the fourth channel is partitioned into 106, 26, and 106-tone resource units, the resource unit non-allocation information may indicate that the 26-tone resource unit is not assigned to any user through, e.g., a bitmap per Chen. SAMSUNG-1008, [0075], [0089]-[0093], Figs. 4, 12- 14; SAMSUNG-1009, [0035]-[0043], Figs. 2-4; SAMSUNG- 1010, 2-6, 10-14. Ex. 1003 ¶¶ 178–181 (alterations in original) (footnote omitted). We determine that this testimony of Dr. Buehrer is supported and reasonable and sufficiently persuasive and credible to support institution. We also note that Patent Owner does not, at least at this stage, provide any contradictory expert testimony.17 We have considered Patent Owner’s arguments relating to the disputed limitations and this ground and found them not to be as well-supported as the Petitioner’s showing for essentially the same reasons as discussed above with regard to Ground 1A. Based on the current record, we determine that there is a reasonable likelihood that Petitioner will prevail with respect to the unpatentability of claims 1–12 of the ’595 patent based on a combination of the teachings and suggestions of Chen and Wu.” slip op. at 29

“We disagree. Although claim 1 recites step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Here, nothing in the express claim language precludes performing step 1d before step 1b. The claim does not expressly recite signaling the device(s) previously “identified as available.” Nor does the claim otherwise specify that step 1b must precede step 1d. For example, the claim does not contain temporal terms like “then,” “next,” or “further.” Although Patent Owner points out that a term of step 1d (i.e., “the” one more available devices) derives antecedent basis from step 1b, this alone does not require performing step 1b before step 1d. PO Resp. 5, 10; Sur-reply 11.

“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

“Petitioner proposes “a person having at least a Bachelor’s Degree in electrical engineering, computer science, or computer engineering, or undergraduate training in an equivalent field and at least two years of relevant experience in electronic gaming technology.” Pet. 10 (citing Ex. 1003 ¶¶ 22–26). Petitioner further notes that “[a]dditional graduate education could substitute for professional experience, and significant work experience could substitute for formal education.” Id. 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

“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 “first payout . . . wherein the first payout is higher.” See Pet. 33–35. 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 first payout that receives Kido’s accumulated Prog bonus payout is necessarily higher than a second payout that does not receive the Prog bonus. Pet. 35.

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. 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
