          Appeal No. 2002-1280                                                        
          Application 08/995,996                                                      

               Appellant argues that there is no motivation in the                    
          references to modify Drori, a single receiver in a vehicle                  
          receiving control signals from multiple transmitters, in view of            
          Karasawa, which teaches controlling multiple receivers with a               
          single transmitter (Br15-16; RBr8).                                         
               Drori teaches that "other means known in the art could be              
          provided on the encoder for specifically generating an encoded              
          signal" (col. 7, lines 56-58).  This provides express motivation            
          for using known ways of setting a code in Drori, such as the                
          keypad input taught in Karasawa.                                            
               Appellant argues that a distinction between the present                
          invention and Drori is that the transmitting unit, upon reception           
          of the user defined code from the user, not only sets that code             
          in the transmitting unit but also automatically transmits the               
          code to the receiver to set the code (Br11; Br12; Br14; Br20).              
               The limitation in question is: "a user defined code setting            
          mode in which said transmitter is responsive to user entry into             
          the transmitter by means of such data input keys of a user                  
          defined code for setting and storing the user defined code in the           
          transmitter and for transmitting the user defined code."  The               
          limitation that a user defined code is set and stored in the                
          transmitter is clearly met by the combination.  However, it does            
          not appear that combination meets the limitation of "transmitting           
          the user defined code" in a user defined code setting mode.  The            

                                       - 10 -
