          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).                                                            
                                          5
