          Appeal No. 2000-2294                                                        
          Application No. 08/511,425                                                  


               As indicated by the cases just cited, the Examiner has 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.                                                  
               With respect to the appealed independent claims 59, 62,                
          and 69, the Examiner has never attempted to show how each of                
          the claimed limitations is suggested by the teachings of the                
          applied prior art.  Instead, the Examiner has taken the                     
          position (Answer, page 9) that Appellants’ invention basically              
          consists of three elements, a test wafer, an interconnect                   
          media, and a product wafer.  To this basic combination of                   
          elements, the Examiner has added bits and pieces from various               
          secondary references to address such features as temperature                
          control and blocking  circuitry.  Nowhere, however, does the                
          Examiner address the specific language of the claims.  For                  
                                          14
