          Appeal No. 1997-1451                                                        
          Application 08/145,974                                                      


          application of impermissible hindsight derived from the                     
          appellant's own disclosure rather than upon some teaching,                  
          suggestion or incentive derived from the applied prior art.                 
          W. L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540,                 
          1551, 220 USPQ 303, 312-313 (Fed. Cir. 1983).  Accordingly, we              
          cannot sustain the examiner's § 103 rejection of the claims on              
          appeal as being unpatentable over Van Beersel in view of                    
          Weatherby and Wetmore.                                                      









               This decision of the examiner is reversed.                             
                                      REVERSED
