          Application No. 08/922,521                                                  


          rejection, we make reference to the final rejection (Paper No.              
          4, mailed January 19, 1999) and the answer (Paper No. 13,                   
          mailed March 22, 2000) for the examiner's complete reasoning                
          in support of the rejection, and to the brief (Paper No. 12,                
          filed December 23, 1999) and reply brief (Paper No. 14, filed               
          May 11, 2000) for the appellants' arguments thereagainst.                   


                                       OPINION                                        
               In reaching our decision in this appeal, we have given                 
          careful consideration to the appellant's specification and                  
          claims, to the applied prior art, and to the respective                     
          positions articulated by the appellant 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 claims under appeal.  Accordingly, we will not sustain the              
          examiner's rejection of claims 1 to 6 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
