          Appeal No. 1997-2107                                                        
          Application No. 08/309,577                                                  


               These circumstances lead us to the determination that the              
          examiner's conclusion of obviousness is based upon                          
          impermissible hindsight derived from the appellant's own                    
          disclosure rather than some teaching, suggestion or incentive               
          derived from the applied prior art.  It follows that the                    
          examiner's § 103 rejection of claims 1 and 9 as being                       
          unpatentable over Hardman is improper and cannot be sustained.
