          Appeal No. 1997-0281                                       Page 6           
          Application No. 08/351,874                                                  


               We begin by noting the following principles from In re                 
          Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956 (Fed. Cir.               
          1993).                                                                      
               In rejecting claims under 35 U.S.C. Section  103,                      
               the examiner bears the initial burden of presenting                    
               a  prima facie case of obviousness.  In re Oetiker,                    
               977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir.                   
               1992). Only if that burden is met, does the burden                     
               of coming  forward with evidence or argument shift                     
               to the applicant.  Id.  "A prima facie case of                         
               obviousness is established when the teachings from                     
               the prior art itself would appear to have suggested                    
               the claimed subject matter to a person of ordinary                     
               skill in the art."  In re Bell, 991 F.2d 781, 782,                     
               26 USPQ2d 1529, 1531 (Fed. Cir. 1993) (quoting In re                   
               Rinehart, 531 F.2d 1048, 1051, 189 USPQ 143, 147                       
               (CCPA 1976)). If the examiner fails to establish a                     
               prima facie case, the rejection is improper and will                   
               be overturned.  In re Fine, 837 F.2d 1071, 1074, 5                     
               USPQ2d 1596, 1598 (Fed. Cir. 1988).                                    
          With these in mind, we analyze the appellant’s argument.                    


               The appellant argues, “Breakover diodes and Zener diodes               
          are distinct devices with completely different architectures                
          and operating different architectures and operating                         
          characteristics. As such, breakover diodes and Zener diodes                 
          cannot be used interchangeably and are, in fact, suited for                 
          completely different applications."  (Dolmovich Decl., ¶ 3.)                
               He adds, “the rejections ... are improperly based on a
