          Appeal No. 1997-0917                                                         
          Application 08/309,565                                                       


          instruction from the controller or the contents of the                       
          configuration register to select one of the data lines and                   
          applying the data received directly from the source output                   
          port of the multiplexer means thereto.                                       
               The Examiner relies on the following reference:                         
          Li                       5,058,001                      Oct. 15,             
          1991                                                                         
               Claims 1 through 13 stand rejected under 35 U.S.C. § 103                
          as being unpatentable over Li.                                               
               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,                 
                                           4
