          Application No. 08/703,932                                                  


                                       OPINION                                        
               In reaching our decision in this appeal, we have given                 
          careful consideration to the appellants' specification and                  
          claims, to the applied prior art references, the declaration                
          of James E. Heider (Paper No. 6, filed January 16, 1996) 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 is insufficient to                   
          establish a case of obviousness with respect to the claims                  
          under appeal.  Accordingly, we will not sustain the examiner's              
          rejection of claims 1, 4 to 16, 22 and 23 under 35 U.S.C. §                 
          103.  Our reasoning for this determination follows.                         


               A case of obviousness is established by presenting                     
          evidence that would have led one of ordinary skill in the art               
          to combine the relevant teachings of the references to arrive               
          at the claimed invention.  See In re Fine, 837 F.2d 1071,                   
          1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988) and In re Lintner,               
          458 F.2d 1013, 1016, 173 USPQ 560, 562 (CCPA 1972).
