Appeal No. 2000-0459 Application 08/838,584 polyolefin composition. The examiner has not established why the skilled artisan would have selected from this laundry list, the combination of components set forth in claim 29, especially when Seltzer’s use of stearates is not required (column 16, lines 54- 60). More importantly, the examiner has not explained why one of ordinary skill in the art would have selected the disclosed stearates in conjunction with the other components recited in claim 29. Absent appellants’ disclosure, we are unable to find the required reason, suggestion or motivation that would lead the skilled artisan to select appellants’ combination of components from Seltzer or Bohshar, or to modify Caselli in view of Seltzer or Bohshar. Therefore, we determine the examiner has not made out a prima facie case with respect to the teachings of Seltzer and Bohshar. We only find a prima face case to the extent the examiner relies upon Caselli, for the reasons set forth below. Appellants admit that the SANDOSTAB P-EPQ stabilizer of Caselli is within the definition of component a) recited in claim 29. (brief, page 8). Appellants also admit that the HALS compound disclosed in Caselli corresponds to their claimed component c). (brief, page 8). With respect to appellants’ claimed component b), appellants argue that the sodium stearate disclosed in Caselli is merely optional and is “added before or after rather than as part of the stabilizer composition” of Caselli, and appellants refer to column 8, lines 44-53 of Caselli. (brief, page 9). Appellants also argue that Caselli teaches that calcium stearate, which is outside the definition of their component b), may be used in place of sodium stearate. (brief, page 9). 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
