          Appeal No. 97-1931                                                          
          Application 08/364,826                                                      


          implemented at the retail level.  In other words, Dworkin cannot            
          be distinguished based only on the size of the purchaser or the             
          size of the order.  The artisan would have recognized that the              
          same principles apply regardless of the size of the order to be             
          made.  Therefore, in considering the obviousness of the claimed             
          invention with respect to Dworkin, the operation of Dworkin must            
          be considered as it would apply to the same type of retailer-               
          wholesaler relationship as disclosed by appellants.                         



          We now consider the specific rejection of each of the                       
          claims under 35 U.S.C. § 103.  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                



                                          7
