         Appeal No. 1998-2981                                                      
         Application No. 08/763,390                                                


              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., Inc. v. Garlock                
         Inc., 721 F.2d 1540, 1548, 220 USPQ 303, 309 (Fed. Cir. 1983),            
         cert. denied, 469 U.S. 851 (1984).                                        


              Claims 1 and 5, which depend therefrom, recite use of two            
         regions of stress control material.  The first region is "in              
         contact with a cut end of the cable shield and [extends] along            
         the cable insulation" and the second region is "disposed in               

                                         7
