The Board denied rehearing, leaving institution denied because Petitioner did not show a reasonable likelihood of prevailing on claims 1–22 under the challenged obviousness grounds.

“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. Dec. 17–18. Petitioner did not acknowledge this critical difference in the Petition, and continues not to do so in its Rehearing Request.” slip op. at 5

“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
- Obviousness (§103) › KSR rationalesMotivation not foundNot shown unpatentable
“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
