          Appeal No. 2001-2212                                                        
          Application No. 09/019,409                                                  


          particular art would have suggested to one of ordinary skill in the         
          art the obviousness of the invention as set forth in claims 1-3,            
          6, 7, and 12-20.  Accordingly, we affirm.                                   
               Appellants have nominally indicated (Brief, page 5) that the           
          appealed claims do not stand or fall together and have made several         
          arguments in response to the Examiner’s obviousness rejection.  We          
          will address these arguments accordingly and will consider the              
          appealed claims separately only to the extent that separate                 
          arguments are of record in this appeal.  Any dependent claim not            
          argued separately in the Brief will stand or fall with its base             
          claim.  Note In re King, 801 F.2d 1324, 1325, 231 USPQ 136, 137             
          (Fed. Cir. 1986); In re Sernaker, 702 F.2d 989, 991, 217 USPQ 1, 3          
          (Fed. Cir. 1983).                                                           
               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 Appellants 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         
                                          4
