transmitter, the receiver had to be sent to the manufacturer
(col. 2, lines 19-23). The invention in Drori allows the
receiver to be electronically programmed by the user without
opening the transmitter and without coding the transmitter or
changing or encoding the receiver (col. 2, lines 34-41).
Drori states (col. 7, lines 52-58):
The transmitter 10 generally comprises the encoder 16 which
may be suitably encoded by the manufacturer so that the user
is not required to encode the same. For this purpose, small
switches may be provided on the encoder, or other means
known in the art could be provided on the encoder for
specifically generating an encoded signal.
One of ordinary skill in the art, reading this passage in
conjunction with the background of the invention, would
appreciate that this refers to the security code or "signature"
code and that although, for simplicity, the user is not required
to encode the transmitter, the user is not precluded from
defining the code. The passage indicates that any means known in
the art could be used to encode the transmitter, where we find
that the "signature" code, when set by a user, corresponds to the
claimed "user defined code" set during a "user defined code
setting mode." Drori teaches that when the user desires to match
a transmitter 10 to a receiver 14, the receiver is placed in the
program mode (col. 17, lines 8-17), which we find corresponds to
the claimed "user defined code setting mode." The receiver
stores the "signature code" from the transmitter, which
