          Appeal No. 1999-0246                                                        
          Application 08/641,629                                                      

               Appellants bear the burden of showing that the evidence                
          on which the examiner relies is insufficient to establish a                 
          prima facie case of obviousness or that appellants have                     
          provided evidence which rebuts the prima face case of                       
          obviousness.  See In re Rouffet, 149 F.3d 1350, 1355 47 USPQ2d              
          1453, 1455 (Fed. Cir. 1998):                                                


                    To reject claims in an application under section                  
               103, an examiner must show an unrebutted prima facie                   
               case of obviousness.  See In re Deuel, 51 F.3d 1552,                   
               1557, 34 USPQ2d 1210, 1214 (Fed. Cir. 1995).  In the                   
               absence of a proper prima facie case of obviousness,                   
               an applicant who complies with the other statutory                     
               requirements is entitled to a patent.  See In re                       
               Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444                     
               (Fed. Cir. 1992).  On appeal to the Board, an                          
               applicant can overcome a rejection by showing                          
               insufficient evidence of prima facie obviousness or                    
               by rebutting the prima facie case with evidence of                     
               secondary indicia of nonobviousness.  See id.                          
          Appellants challenge the sufficiency of the evidence on which               
          the examiner's prima facie case is based.                                   
          E.  The merits of the rejection                                             
               Smitt discloses a computer network 11 which includes a                 
          control and switching device 17 for selectively coupling a                  
          remote                                                                      



                                        - 5 -
