Appeal No. 95-0143
Application 07/865,849
over the combination of Pogue and Clark is improper because those
of ordinary skill in the art would not be motivated by Pogue or
Clark to modify the Pogue apparatus as suggested by the
Examiner’s proposed modification. Appellants point out that
Pogue fails to teach storing in the lock an identification number
of a lock as well as storing in the lock any encryption code
associated with the lock. Appellants further point out that
Pogue does not teach storing in the key a list of lock
identification numbers and corresponding encryption codes.
Finally, Appellants point out that Pogue does not teach a key
including means for receiving the identification number of a lock
and a seed number from the lock and means for encrypting the
received seed number with an encryption code retrieved from the
key memory corresponding to the received identification number to
generate an encrypted seed number as recited in Appellants’ claim
1.
The Examiner argues that Clark teaches storing a list of
lock identification numbers and corresponding encryption codes in
the key. The Examiner argues on pages 3 and 4 of the answer that
it would have been obvious to modify the Pogue system so that the
key would store a list of lock and corresponding encrypting codes
for the ability to operate multiple locks.
