          Appeal No. 95-2623                                                          
          Application 08/084,623                                                      


          It is our view, after consideration of the record                           
          before us, that the collective evidence relied upon and the                 
          level of skill in the particular art would have suggested to                
          one of ordinary skill in the art the obviousness of the                     
          invention as set forth in claims 22-26.  Accordingly, we                    
          affirm.                                                                     
          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).                                                            
          With respect to independent claim 22, it is the                             
          position of the examiner that the collective teachings of                   
                                          4
