          Appeal No. 96-2576                                                          
          Application 08/148,271                                                      


          776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert.                
          denied, 475 U.S. 1017 (1986); ACS Hospital Systems, Inc. v.                 
          Montefiore Hospital, 732 F.2d 1572, 1577, 221 USPQ 929, 933 (Fed.           
          Cir. 1984).  These showings by the examiner are an essential part           
          of complying with the burden of presenting a prima facie case of            
          obviousness.  Note In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d            
          1443, 1444 (Fed. Cir. 1992).                                                
          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.  Since the differences between the           
          claimed invention and the applied prior art in this case appear             
          to have been properly identified and argued by the examiner and             
          appellant, the question for disposition is whether the examiner’s           
          conclusion of obviousness is supported by the evidence of record            
          in this case and the analysis provided by the examiner.                     
          With respect to independent claim 1, appellant argues                       
          that the following recitations of the claim are not suggested by            
          the applied prior art: (1) the semiconductor chip has a plurality           

                                          5
