Appeal No. 2002-1280
Application 08/995,996
"does not specifically teach a user defined code setting function
in the transmitter, where the user actually sets the codes from a
key input" (FR3; EA4), but "Karasawa et al. teach (see column 14
lines 16-41 and fig. 21) setting user defined codes (in the
transmitter) for locking devices in order to perform control
operation from a key input or keypad" (FR3; EA4). "Therefore it
would have been obvious to one of ordinary skill in the art to
use user defined codes in the transmitter and receiver to control
an apparatus remotely by inputting user defined code setting
function as evidenced by Karasawa in the transmitter, in order to
provide a security system and to set or update codes in the
receiver for the purpose of controlling access permission as
discussed by Drori, to control locking devices remotely to
increase security" (FR4; EA4).
Analysis
After consideration of appellant's arguments, we agree with
the examiner that it would have been obvious to set the signature
code in the transmitter of Drori by a user with a keypad as
taught by Karasawa. The motivation is found in Drori's express
teaching that "other means known in the art could be provided on
the encoder for specifically generating an encoded signal"
(col. 7, lines 56-58) and, thus, it is not necessary to decide
whether the examiner's stated motivation would be sufficient.
