          Appeal No. 1999-2568                                                        
          Application No. 08/640,096                                                  


          disclosed therein are not configured as drivers, but as low                 
          impedance paths to ground when they are gated on (column 1,                 
          lines 39 through 52).  As each of the gates is turned on, the               
          current from single driver 14 is diverted from the current                  
          sensing device 15 to ground.  Thus, we agree with the                       
          appellants (reply brief, page 2) that “Belluche is incapable                
          of meeting the functional limitations” of the claims.  The                  
          anticipation rejection of claims 1 through 3, 7 and 8 is                    
          reversed because of the lack of “a single trip propagation                  
          delay” (claim 1), and “a plurality of drivers disposed along a              
          bus” (claim 7) in Belluche.                                                 
               Turning lastly to the obviousness rejection of dependent               
          claims 2, 4 through 6, 9 and 10 based upon the sole teachings               
          of Belluche, this rejection is reversed for all of the reasons              
          that the anticipation rejection of claims 1 through 3, 7 and 8              
          was reversed.                                                               









                                          7
