              Application No. 08/252,896                                                                                


                                                   BACKGROUND                                                           

                     The appellants’ invention relates to a multi-port switching system and method for a                
              computer bus.  An understanding of the invention can be derived from a reading of                         
              exemplary claim 1, which is reproduced below.                                                             
              1.     A multi-port switching system for a computer bus, said multi-port switching system                 
              being operative for selectively coupling one of  n  bus initiator devices to a bus target                 
              device, said switching system comprising:                                                                 
                     a plurality m of initiator buses, wherein m and n are integers, and wherein n is                   
              greater than m,                                                                                           
                     a plurality m of switching circuits,                                                               
                     each of said switching circuits having a bus initiator interface that is coupled                   
              through an initiator bus to a subset of said n bus initiator devices, each of said switching              
              circuits having a bus target interface that is coupled to said bus target device through said             
              computer bus,                                                                                             
                     each of said switching circuits being responsive to one of said subset of said n bus               
              initiator devices connected to said bus initiator interface for coupling said one bus initiator           
              device to said bus target device by way of said bus target interface and said computer                    
              bus; and                                                                                                  
                     each of said switching circuits generating a busy signal to a remainder of said                    
              other switching circuits while said one bus initiator device is coupled to said bus target                
              device.                                                                                                   
                     The prior art reference of record relied upon by the examiner in rejecting the                     
              appealed claims are:                                                                                      
              House et al. (House)               5,274,783                          Dec. 28, 1993
