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
