          Appeal No. 1998-2189                                                        
          Application 08/097,372                                                      

          Thus, the Examiner has failed to establish a prima facie case               
          of obviousness as to the reasons to combine.                                
                                     CONCLUSION                                       
               Because the Examiner (1) failed to show the limitation of              
          "said clock signal being exclusively driven by the first                    
          processor means," and (2) provided no explanation of how Bush               
          and Costes should be combined to produce the claimed subject                
          matter, we conclude that the Examiner has not established a                 
          prima facie case of obviousness as to claim 1 and its                       
          dependent claims 2-9.  Independent claim 10 stands or falls                 
          together with claim 1.  Independent claim 13 contains a                     
          limitation in addition to the limitations of claim 1 and, so,               
          is also patentable over the combination of Bush and Costes.                 
          Accordingly, the rejection of claims 1-10 and 13 is reversed.               
                                      REVERSED
