          Application No. 09/069,192                                                  


          in support of the rejection, and to the brief (Paper No. 10,                
          filed May 22, 2000) and reply brief (Paper No. 13, filed                    
          September 27, 2000) for the appellants' arguments                           
          thereagainst.                                                               


                                       OPINION                                        
               In reaching our decision in this appeal, we have given                 
          careful consideration to the appellants' specification and                  
          claim 1, to the applied prior art, and to the respective                    
          positions articulated by the appellants and the examiner.                   
          Upon evaluation of all the evidence before us, it is our                    
          conclusion that the evidence adduced by the examiner is                     
          insufficient to establish a prima facie case of obviousness                 
          with respect to the claim under appeal.  Accordingly, we will               
          not sustain the examiner's rejection of claim 1 under 35                    
          U.S.C. § 103.  Our reasoning for this determination follows.                


               In rejecting claims under 35 U.S.C. § 103, the examiner                
          bears the initial burden of presenting a prima facie case of                
          obviousness.  See In re Rijckaert, 9 F.3d 1531, 1532, 28                    
          USPQ2d 1955, 1956 (Fed. Cir. 1993).  A prima facie case of
