          Appeal No. 2000-0482                                                        
          Application 08/569,256                                                      


                    composition or device, or carry out the                           
                    claimed process; and (2) whether the prior                        
                    art would also have revealed that in so                           
                    making or carrying out, those of ordinary                         
                    skill would have a reasonable expectation                         
                    of success.  Both the suggestion and the                          
                    reasonable expectation of success must                            
                    be founded in the prior art, not in the                           
                    applicant’s disclosure.                                           
          In re Vaeck, 947 F.2d 488, 493, 20 USPQ2d 1438, 1442 (Fed. Cir.             
          1991)(citation omitted).                                                    
                    The examiner relies on each of the primary references             
          as disclosing a mold release composition comprising one or more             
          of components A and C3 of the claimed invention.  Examiner’s                
          Answer, Paper No. 20, mailed July 27, 1999, page 3, paragraph               
          (10).  The examiner acknowledges that the primary references do             
          not disclose component B, i.e., a polytetrafluoroethylene (PTFE)            
          having a number-average molecular weight of 50,000 to 500,000.              
          However, the examiner maintains that it would have been obvious             
          to have used component B in the compositions of the primary                 
          references in view of Wagner which discloses a PTFE release agent           
          having a molecular weight of 30,000 to 200,000.
