          Appeal No. 96-0950                                                          
          Application No. 07/727,932                                                  


          through column 10, line 27.  For example, the occupation bus is             
          in a 1 state during an exchange of data between a sending                   
          processor and a receiving processor and is in the 0 state when              
          the data bus is at rest.  Column 4, line 65 through column 5,               
          line 2.                                                                     
               Katzman discloses in Figure 1 a centralized controller 37              
          for arbitrating requests for bus access among competing                     
          processors 33.  The centralized controller 37 includes processor            
          select logic 85 (Figure 3) which determines the priority of data            
          transfers.  Controller 37 has a separate select line 63 (Figure             
          2) to each processor.  Controller 37 awards bus access to one               
          processor by sending a signal over that processor’s individual              
          select line.  Column 81, lines 16 through 68.                               
                                     DISCUSSION                                       
          Claims 1-6 and 11-13                                                        
               Claims 1-6 and 11-13 recite a data gathering system having             
          transfer control means for (1) checking a number of data on a               
          data bus and (2) determining an order of transfer by the                    
          respective transmitting processor of said plurality of                      
          transmitting processors.                                                    
               The examiner states that Quinquis has means for performing             
          function (1) and that it would have been obvious to incorporate
