          Appeal No. 95-3290                                                          
          Application 08/062,156                                                      


          at least two responsibilities in setting forth a rejection                  
          under                                                                       
          35 U.S.C. § 103.  First, the examiner must identify all the                 
          differences between the claimed invention and the teachings of              
          the prior art.  Second, the examiner must explain why the                   
          identified differences would have been the result of an                     
          obvious  modification of the prior art.  In our view, the                   
          examiner has not properly addressed his first responsibility                
          so that it is impossible that he has successfully fulfilled                 
          his second responsibility.                                                  
          In our view, each of the independent claims recites                         
          subject matter that the examiner has asserted is taught by the              
          applied prior art, but we are unable to find such teachings in              
          the applied prior art.  Thus, there are differences between                 
          the claimed invention and the teachings of the applied prior                
          art which have gone unrecognized by the examiner.  Since the                
          examiner has not identified these differences, the rejection                
          fails to provide arguments as to why these differences would                
          have been obvious to one having ordinary skill in the art.                  
          Therefore, the prima facie case of obviousness has not been                 
          properly established for these claims.                                      
                                          6
