Appeal 2006-2948 Application 10/194,872 of both Appellants' and Bloice's processes. Certainly, it would have been a matter of obviousness for one of ordinary skill in the art to determine the specific point in the process when a countermeasure must be employed, and it would have been within the level of one of ordinary skill in the art to determine the optimum point in the process for effecting a countermeasure against the continuous deterioration of the felt's permeability. In re Boesch, 617 F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980). As a final point, we note that Appellants base no argument upon objective evidence of nonobviousness, such as unexpected results, which would serve to rebut the prima facie case of obviousness established by the Examiner. In conclusion, based on the foregoing, the Examiner's decision rejecting the appealed claims is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 CFR § 1.136(a)(1)(iv) (2004). AFFIRMED clj Todd T. Taylor Taylor & Aust, P.C. 142 S.
