          Appeal No. 1997-3027                                                        
          Application 08/301,926                                                      


          patenting rejection of claim 1 was withdrawn upon the filing                
          of a terminal disclaimer, note Advisory Action, Paper No. 10.               
                    Rather than reiterate the arguments of Appellants                 
          and the Examiner, reference is made to the brief and answer                 
          for the respective details thereof.                                         
                                       OPINION                                        
                    After a careful review of the evidence before us, we              
          will not sustain the rejection of claims 1 through 13 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 reasonable teachings or suggestions                
          found in the prior art, or by a reasonable inference to the                 
          artisan contained in such teachings or suggestions.  In re                  
          Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6 (Fed. Cir. 1983).                
                                                                                     
                    The Examiner reasons that APA (Appellants’ Figure 2)              
          teaches the claimed invention except for the use of two                     
          Schottky diodes, instead of one.  Fraser is then cited for the              


                                          3
