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.
