          Appeal No. 00-0833                                                          
          Application 08/985,676                                                      
               The Examiner bears the burden of establishing a prima                  
          facie case of obviousness based upon the prior art.  The                    
          Examiner can satisfy this burden only by showing some                       
          objective teaching in the prior art or that knowledge                       
          generally available to one of ordinary skill in the art would               
          lead that individual to combine the relevant teachings of the               
          references.  The patent applicant may then attack the                       
          Examiner's prima facie determination as improperly made, or                 
          the applicant may present objective evidence tending to                     
          support a conclusion of nonobviousness.  In re Fritch, 972                  
          F.2d 1260, 1265, 23 USPQ2d 1780, 1783 (Fed. Cir. 1992)                      
          (quoting In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598               
          (Fed. Cir. 1988).                                                           
               In rejecting claims under 35 U.S.C. 103, the examiner is               
          to establish a factual basis to support the legal conclusion                
          of obviousness.  In order to establish a prima facie case of                
          obviousness there must be some teaching, suggestion or                      
          motivation in the prior art to make the specific combination                
          that was made by the applicant.  In re Dance, 160 F.3d 1339,                
          1343, 48 USPQ2d 1635, 1637 (Fed. Cir. 1998).  Based on the                  
          record before us, the examiner has failed to set forth a prima              
          facie case of obviousness.                                                  
                                          6
