“Petitioner misstates the Decision’s reasoning. As is clear from the previous discussion, we determined that Petitioner’s articulated reasons for combining EP’536 with CN’180 lacked a rational underpinning, not because “EP’536 does not relate to ‘air bags,’” but because the means by which EP’536’s device inflates differs fundamentally from that of CN’180’s device.

“EP’536 with CN’180 lacked a rational underpinning because EP’536’s inflation mechanism differs fundamentally from CN’180’s inflation mechanism. Dec. 17–18. As we stated, whereas CN’180’s fall-protection belt uses an airbag that requires an external source of pressurized air to inflate, EP’536’s garment does not need an external inflation device because “the gas generating agent 18 in each envelope automatically generates gas and inflates the envelopes in response to rising temperatures.” Id. at 18 (citing Ex. 1004 ¶ 15; Ex. 1005 ¶¶ 5, 19). This difference reflects the fundamentally different purposes of the two devices: CN’180’s device is designed to provide “fall protection” to, e.g., “elderly people,” (Ex. 1005 ¶ 1, 3), whereas EP’536’s device provides “adaptive thermal insulation” for, e.g., garments worn by fire fighters. Ex. 1004 ¶¶ 1–3, 250. Because of the different means by which EP’536’s and CN’180’s devices inflate and the different purposes for doing so, we were not persuaded that one of ordinary skill in the art would have combined the references as Petitioner proposed. Dec. 18. We further noted that the modification would not have improved the reusability of EP’536’s device “by having only one mechanism to recharge,” because EP’536’s “gas generating agent does not need any ‘mechanism to recharge.’” Dec. 18. Instead, we noted EP’536’s teaching that its gas generating agent “automatically recombines or condenses in response to a temperature decrease to return the envelopes, and therefore the garment, to its original thickness, at which point the gas generating agent is ready for subsequent reactivation.” Id. (citing Ex. 1004 ¶¶ 139–141). Finally, we determined that replacing EP’536’s envelopes with CN’180’s airbag “would have made EP’536’s invention unsuitable for its intended purpose: providing a protective garment with ‘adaptive thermal insulation.’” Dec. 19. We stated that “Petitioner does not suggest, and we have found nothing in the record to establish, that CN’180’s airbag would provide this feature.” Id. at 20.” slip op. at 3

“rationales for combining EP’536 and CN’180. Reh’g Req. 6–7. First, Petitioner asserts that we “improperly rejected Petitioner’s ‘simple substitution’ evidence in view of [the Board’s] incorrect conclusion that EP’536 does not disclose an ‘external source of inflation [EP’536’s dosing aids].’” Id. at 6 (citing Dec. 18–19). This argument is unpersuasive at least because, as we discussed above, EP’536’s dosing aids do not constitute an external source of inflation. Petitioner further argues that we incorrectly evaluated its “obvious to try” rationale because, contrary to our analysis, Petitioner did in fact identify a problem to be solved by its “finite number of solutions”: “simplify[ing] the design and reduc[ing] the number of required inflation mechanisms.” Id. at 6–7. The Petition’s entire “obvious to try” discussion is as follows: [A] POSITA would have found it obvious to try a one-piece airbag 10 with strip-shaped inflation units 12 in the EP’536- CN’180 airbag system because it would have been a selection from a finite number of identified predictable solutions (i.e., using one chamber with connected individual inflation units 12 versus multiple individual envelopes 20). 5 Petitioner also argues that dosing aids are “needed in order to make the disclosed device reusable.” Reh’g Req. 5–6. This is incorrect, as EP’536 conveys that the reusability of the device is a result of the gas generating agent condensing or recombining when temperatures fall. Ex. 1004 ¶¶ 139– 141. Even if it were true, however, it is unclear how it would support Petitioner’s argument. Pet. 16. As is evident, Petitioner did not identify a design need, market pressure, or other problem that would have been addressed by its identified “solutions,” and therefore we were not persuaded by this rationale. Dec. 19. Petitioner’s attempt to cure this deficiency in its Rehearing Request is tardy. We cannot misapprehend or overlook an assertion that Petitioner fails to make in the Petition. It is also insufficient. Petitioner does not provide any evidence of a known design need or market pressure to “simplify [EP’536’s] design” or reduce the number of “required inflation mechanism” it uses.” slip op. at 7

“Ex. 1003 ¶ 179. But Dr. Kim does not cite to any additional supporting evidence or provide any technical reasoning to support his statements. The notion that one can reduce the time between measurements by, e.g., reducing the number of frequencies measured, has intuitive appeal and appears mathematically correct. However, the absence of technical reasoning and supporting evidence diminishes the persuasiveness of Dr. Kim’s testimony that the POSA would made such modifications to reduce the time between measurements. Dr. Kim does provide some technical reasoning in connection with his discussion of eliminating all reference channels as a way to get the time resolution down to the levels required by, e.g., claim 14, which recites a millisecond time resolution of “less than 5 milliseconds.” See e.g., Ex. 1003 ¶ 172 (“A POSA seeking to study biological cell phenomena occurring on the order of a few milliseconds would have recognized that after measuring the reference network channels at the start, the reference network channels would not need measured again for some time, e.g., because temperature and other drift factors do not change appreciably on a millisecond time scale.”). However, even if we were to credit this testimony, Dr. Kim still lacks support and reasoning for the selection of the other parameters in his noreference-channel calculations. See, e.g., id. ¶ 173 (positing, but not providing technical reasoning for using, a no-reference-channel impedance system with 16 wells, a single 10kHz measurement frequency, and 16 daughter boards that measure simultaneously rather than sequentially).” slip op. at 29

“We disagree that Dr. Durham does not possess the necessary level of skill in the art to qualify as an expert in this case. Looking at the specification of the ’689 patent and the prior art of record, we think Masaba sets the bar too high. We acknowledge that one of ordinary skill in the art should have some education and/or experience in the mechanical art of conveying aggregate materials, but we do not think opining on the ’689 patent and asserted prior art necessarily requires that person to have the amount of education and experience that Masaba advocates. The ’689 patent relates generally to an “aggregate transferring system for receiving aggregate from a vehicle and elevating the aggregate to a higher vertical level for deposit into, for example, a silo.” Ex. 1001, 1:15– 18. And, as described in the ’689 patent and discussed later, the transferring system is an assembly of known types of conveyors, such as a belly-dump truck conveyor, a bucket elevator, and an articulated belt conveyor, for transferring the aggregate horizontally and vertically from a belly-dump truck to the discharge point, such as a silo. Without doubt, Dr. Durham has enough education and experience to reliably opine on the combination of known parts.” slip op. at 8
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction needed
“We reject this argument for several reasons. First, nowhere does the plain language of the claims specify how the aggregate is conveyed or moved from the conveyor extension assembly’s inlet to its outlet, be it passively by means of gravity or actively by means of a conveyor belt. Instead, the claims simply use those verbs according to their plain and ordinary meaning, which is “to transfer or deliver” or “to cause to go or pass” from one place to another. See Ex. 3001, 253 (defining “convey”), 760 (defining “move”).10 Second, the specification of the ’689 patent similarly uses these terms in a plain and ordinary sense, without ever attributing to them some sort of special meaning. See, e.g., Ex. 1001, 4:9–12 (“The apparatus 10 is suitable for performing the transfer of aggregate from 10 We reference the original pagination of the dictionary in which these definitions appear. one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate.”). The ’689 patent specification also makes clear that active conveyance of the aggregate is an option and not a requirement of the claimed invention, stating that the conveyor extension assembly “may further include a conveyor belt 150.” Ex. 1001, 10:60–66 (emphasis added). Limiting claim elements 1[h] and 1[i] to a device “for actively conveying” or “for actively moving aggregate” would improperly import limitations from the specification into the claims. Thus, based on the intrinsic evidence, we determine that claim elements 1h and 1k are properly construed to encompass passive and/or active movement of the aggregate via the conveyor extension assembly.” slip op. at 20

“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. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 11

“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. 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. 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
