          Appeal No. 95-4096                                                          
          Application No. 08/188,660                                                  


          bus being an efficient transfer medium for bursty, or high                  
          speed, data appears to be a weak motivation for attempting to               
          use a packet-switched bus in Dashiell when Dashiell does not                
          indicate that the data therein is high speed data of the type               
          of interest in Baxter and there is no indication that the                   
          system of Dashiell would work with a packet-switched bus.  The              
          examiner fails to take into account that the completely                     
          different types of buses do not easily permit the substitution              
          of one for the other without an attendant, more-than-routine,               
          modification of other parts of the system.                                  
               Instant claim 2 clearly calls for the transactions                     
          comprising “a request packet followed at an indeterminate                   
          later time by a reply packet...”  Clearly, the Dashiell system              
          operates in a completely different manner.  There is no                     
          request packet therein which is followed at an indeterminate                
          later time by a reply packet.                                               









                                          9
