Appeal No. 1996-3350 Application 08/187,114 article to recover into conforming engagement with the electrical apparatus (column 3, lines 54-60). Similarly, Nelson teaches that excellent elastic memory is desired for the PST, as measured by the permanent set, as well as several other physical performance criteria (column 4, lines 32-60). Accordingly, the elastic properties of the tubular elastic sleeve would have been recognized as result-effective variables by one of ordinary skill in the art, depending on the size of the cables being spliced, the sealing pressure and the recovery time desired. Optimization of such properties would have been well within the ordinary skill in the art. See In re Boesch, 617 F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980). See Nelson, column 4, lines 3-7, where Nelson teaches the specific monomer systems to prepare the elastomers that will provide the necessary physical characteristics for his PST. For the foregoing reasons, we determine that the properties of the elastic sleeve recited in claim 13 on appeal would have been result-effective variables readily optimized by one of 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
