Appeal 2007-2235 Application 10/138,617 discloses that “[t]he landfill’s aerobic operation is optimized by adjusting air injection and leachate application rates so that the waste mass temperatures remain stable preferably between approximately 120 degrees F. and approximately 140 degrees F. after aerobic conditions have been reached . . .” (id. at col. 6, ll. 57-62). Hudgins also discloses that “[t]arget waste mass moisture is roughly 40%-60% by weight following the initial saturation of the waste mass” (id. at col. 6, ll. 65-67). In comparison, Appellant discloses that the landfill should be maintained at “a temperature of from about 70° to about 180° F” (Specification 12, ¶ 45) and “preferably maintained at moisture levels between about 20% and about 60% moisture as a weight percentage of wet waste (id. at 13, ¶ 46). Because Hudgins discloses using water to maintain the same temperatures and moisture levels disclosed by Appellant as being optimal in a landfill bioreactor, on the current record it appears that Hudgins discloses adding water to the landfill at the same rate recited in claim 7. “[W]here the Patent Office has reason to believe that a functional limitation asserted to be critical for establishing novelty in the claimed subject matter may, in fact, be an inherent characteristic of the prior art, it possesses the authority to require the applicant to prove that the subject matter shown to be in the prior art does not possess the characteristic relied on.” In re Best, 562 F.2d 1252, 1254-1255, 195 USPQ 430, 433 (CCPA 1977) (quoting In re Swinehart, 439 F.2d 210, 213, 169 USPQ 226, 229 (CCPA 1971)). Appellant has not shown that the amount of water Hudgins adds to the landfill bioreactor is different than the amount recited in claim 7. 17Page: Previous 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Next
