In doing so, the diaphragm prevents the passage of milk from reaching the air pump and facilitates generation of negative pressure during operation.

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

“Mr. Bauer further testifies: For electric-powered breast pumps, the only two options for providing electricity to the pump was either via a wire plugged into an outlet or via a battery, as would have been well-known to a POSITA. It would have been obvious for a POSITA to utilize a battery as the power source for Furrer’s pump as it was one of the two available options and would have provided known benefits. Ex. 1003 ¶ 93. As to why this a person of ordinary skill would have chosen the option of a battery powered breast pump, Mr. Bauer testifies that: Selection of battery power for Furrer’s pump would have beneficially provided a portable system that was usable during travel. Additionally, such a configuration would have allowed the user to move freely about a room, or be positioned in a location within a room without being tethered to a wall plug, allowing the user to, for example, sit or lay in the most convenient location while using the system without having to worry about being close to an outlet. Such mobility provided by selecting battery power for Furrer’s pump would have particularly aligned with Furrer’s suggestion for a ‘hands-free’ and discrete solution. Id.

“A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Patent Owner’s argument is unpersuasive at least because Dinka expressly describes using VoIP technology on computer terminals 102. Ex. 1006, 5:45–48 (“A plurality of computer terminals 102 are shown coupled to the Internet 101, each comprising a network interface for communicating over the Internet.”), 6:7–8 (“Each computer terminal 102 is installed with a communication client application 110.”), 6:23–26 (“The communication client applications 110 [of computer terminals 102] and 113 [of television sets 103] are preferably peer-to-peer clients for setting-up and conducting VoIP calls according to peer-to-peer principles as discussed above.”). Thus, Dinka does not lead a skilled artisan in a direction divergent from the path taken in the ’347 patent. Moreover, “[a] reference may be read for all that it teaches, including uses beyond its primary purpose.” In re Mouttet, 686 F.3d 1322 1331 (Fed. Cir. 2012). Thus, even though Dinka expresses a preference for conducting VoIP calls using a television set, a skilled artisan still would have considered Dinka’s teaching of using computers for such calls. See id. at 1334 (“This court has further explained that just because better alternatives exist in the prior art does not mean that an inferior combination is inapt for obviousness purposes.”).

Ag Pro, Inc., 425 U.S. 273, 282 (1976))).

The Board instituted review of claims 1–22 on all asserted grounds after finding a reasonable likelihood that claims 1–22 would have been obvious over Beel and Dinka.

“In sum, on the current record, Petitioner has shown a reasonable likelihood that claim 1 would have been obvious over Beel and Dinka. f) Claims 2–22 The parties present their arguments for independent claim 11 along with those for claim 1. Pet. 44–45; Prelim. Resp. 19, 23. Claims 2–10 and 22 depend, directly or indirectly, from claim 1. Claims 12–21 depend, directly or indirectly, from claim 11. Patent Owner does not present separate arguments for claim 11 or the dependent claims. We have analyzed Petitioner’s arguments and evidence for claims 2–22 (Pet. 36–46) and, on the current record, conclude that Petitioner has shown sufficiently that claims 2–22 would have been obvious over Beel and Dinka.” slip op. at 25
- Skill levelSkill level petitioner adoptedDecided for petitioner
“III. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner, relying on the testimony of Dr. Almeroth and alleged admissions by Patent Owner in litigation, contends that a person of ordinary skill in the art would have had “a Master of Science (M.S.) degree in electrical engineering or computer science, and five years of work experience in a related field” and that “[a]dditional educational experience could substitute for some of the work experience.” Pet. 8 (citing Ex. 1002 ¶¶ 36–37). “Patent Owner does not dispute Petitioner’s proposed level of skill in the art at this time.” Prelim. Resp. 6. For purposes of this Decision, we adopt Petitioner’s description of the level of ordinary skill in the art, as it is consistent with the technology described in the ’346 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 7

“Patent Owner accepts the Petition’s claim construction for the purposes of” the Preliminary Response. Prelim. Resp. 5–6. In light of Patent Owner’s acceptance, and because the proposed constructions are, on this record, consistent with the evidence cited by Petitioner, we, too, accept Petitioner’s proposals for “providing simulations or translations, as required,” and “data transformations,” as recited in claim 1, for purposes of this Decision. Based on the record before us, we do not find it necessary to provide express claim constructions of any other claim terms. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’”) (quoting Vivid Techs., Inc. v. Am.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“Patent Owner argues that Dr. Almeroth does not provide a reason why a skilled artisan would have been motivated to combine Beel and Dinka, and that, instead, he “summarily concludes that Skype’s status as ‘well-known’ somehow would have motivated the combination of Dinka with Beel.” Prelim. Resp. 16. We disagree. Dr. Almeroth testifies that Skype, as taught in Dinka, would have been an example of the type of application that would have run on Beel’s system and that applying Dinka’s teachings would have improved Beel’s similar system in the same manner as it improved Dinka’s, with predictable results. Ex. 1002 ¶¶ 117, 132. See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007) (“[W]hen a patent ‘simply arranges old elements with each performing the same function it had been known to perform’ and yields no more than one would expect from such an arrangement, the combination is obvious.” (quoting Sakraida v.
