          Appeal No. 1998-1317                                                        
          Application No. 08/522,112                                                  


               We will not sustain the rejection of claims 8-9 under 35               
          U.S.C. § 103.                                                               
               The Examiner has failed to set forth a prima facie case.               
          It is the burden of the Examiner to establish why one having                
          ordinary skill in the art would have been led to the claimed                
          invention by the express teachings or suggestions found in the              
          prior art, or by implications contained in such teachings or                
          suggestions.  In re Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6              
          (Fed. Cir. 1983).  “Additionally, when determining                          
          obviousness, the claimed invention should be considered as a                
          whole; there is no legally recognizable ‘heart’ of the                      
          invention.”  Para-Ordnance Mfg., Inc. v. SGS Importers Int’l,               
          Inc., 73 F.3d 1085, 1087, 37 USPQ2d 1237, 1239 (Fed. Cir.                   
          1995), cert. denied, 117 S.Ct. 80 (1996) citing W.L. Gore &                 
          Assocs. v. Garlock, Inc., 721 F.2d 1540, 1548, 220 USPQ 303,                
          309 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984).                    
               On pages 6-9 of the brief, Appellant argues that                       
          Guberman, Huttenlocher, Stroke and Davida fail to teach                     
          Appellant’s claimed limitations.  In particular, Appellant                  
          argues that neither Guberman or Huttenlocher discloses                      

                                          4
