Appeal No. 2002-0747 Page 11 Application No. 09/006,982 important to their invention and solves problems present in the art (specification, pages 2-12). On the other hand, the examiner has not adduced any evidence in support of his assertions that the claimed “co-location” of the air source and the delivery devices and the use of a plurality of cassettes are “old and well known in the art,” and that positioning the delivery devices in a plurality of cassettes is merely a duplication of known parts for a known purpose. The mere fact that the prior art structure could be modified does not make such a modification obvious unless the prior art suggests the desirability of doing so. See In re Gordon, 733 F.2d 900, 902, 221 USPQ 1125, 1127 (Fed. Cir. 1984). In the present situation, we fail to perceive any teaching, suggestion or incentive which would have led one of ordinary skill in the art to modify the Watt device in such a manner as to meet the terms of claim 1. Watt fails to establish a prima facie case of obviousness with regard to the subject matter recited in claim 1. This being the case, we will not sustain the rejection of claim 1 or, it follows, of claims 2 and 8-18, which depend from claim 1. Claims 3-7 stand rejected as being unpatentable over Watt in view of Spengler, which was cited for its disclosure of “several representative ranges which may be used to assist in determine [sic] proper length & diameter which encompass those set forth in the claims” (Answer, page 10). The examiner goes on to opine that one of ordinary skill in the art would therefore have had the “suggestion/motivation” to “optimize the [Watt] device with these known dimensions in the art in order to produce a more efficient &Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
