              Appeal No. 2003-0405                                                                   Page 10                  
              Application No. 09/635,183                                                                                      


              (2) the processing system executing "a strategy comprising operating the friction brakes                        
              to apply at least some of the reduction in regenerative braking torque as friction brake                        
              torque" as recited in claim 2; and                                                                              
              (3) the processing system executing "a strategy comprising operating the friction brakes                        
              to apply the entire reduction in regenerative braking torque as friction brake torque" as                       
              recited in claim 3.                                                                                             


                      In our view, the above-quoted limitations of claims 2 and 3 are readable on                             
              Kidston when Kidston executes his strategy of ramping down the regenerative blended                             
              brake torque, as shown in Figure 9 with respect to curve 133 starting with the ABS                              
              event indicated.  As this ramp down of regenerative blended brake torque occurs, the                            
              friction brakes will correspondingly ramp up as shown in Figure 9 with respect to curve                         
              136 to produce the total requested brake torque (curve 130 in Figure 9).  At the end of                         
              this strategy of ramping down the regenerative blended brake torque and the ramping                             
              up of the friction brake torque, Kidston will execute his strategy of eliminating                               
              regenerative brake torque and utilizing only friction brake torque as shown in Figure 9.                        
              We find that the processing system of Kidston does                                                              
              (1) execute a strategy comprising reducing, but not completely eliminating, the torque                          
              that is being applied to the drivetrain as regenerative braking torque when a wheel-                            
              condition-initiated triggering event occurs (see Kidston's regenerative braking torque
