          Appeal No. 96-1614                                                          
          Application No. 08/236,660                                                  


          1325, 231 USPQ 136, 137 (Fed. Cir. 1986); In re Sernaker, 702               
          F.2d 989, 991, 217 USPQ 1, 3 (Fed. Cir. 1983).  Accordingly,                
          we will consider a single claim from each rejection as                      
          representative of all the claims within that rejection.                     
          Although appellants’ representative addressed some different                
          claims within each rejection at the oral hearing, the                       
          arguments for separate patentability must appear in the brief               
          in order to obtain the benefits of separate patentability.                  
          As a general proposition in an appeal involving a                           
          rejection under 35 U.S.C. § 103, an examiner is under a burden              
          to make out a prima facie case of obviousness.  If that burden              
          is met, the burden of going forward then shifts to the                      
          applicant to overcome the prima facie case with argument                    
          and/or evidence.  Obviousness is then determined on the basis               
          of the evidence as a whole and the relative persuasiveness of               
          the arguments.                                                              
          See In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444                
          (Fed. Cir. 1992); In re Hedges, 783 F.2d 1038, 1039, 228 USPQ               
          685, 686 (Fed. Cir. 1986); In re Piasecki, 745 F.2d 1468,                   
          1472, 223 USPQ 785, 788 (Fed. Cir. 1984); and In re Rinehart,               
          531 F.2d 1048, 1052, 189 USPQ 143, 147 (CCPA 1976).  Only                   
                                          7
