Appeal No. 1997-0884
Application 08/260,148
circuit having both transmission and reception capability"
(specification, page 1, lines 14-15) and the following prior
art:
Lindmayer et al. (Lindmayer) 5,159,329 October 27,
1992
Bachhuber 5,365,225 November 15,
1994
(April 6, 1990)
Claims 1 and 2 stand rejected under 35 U.S.C. § 102(b) as
being anticipated by Lindmayer. The Examiner states (Final
Rejection, page 2): "Lindmayer shows the claimed method of
preventing the unauthorized learning of a code in a remote
control system. Lindmayer shows modifying the code by erasing
the code. See col. 3, lines 20-32."
Claims 1-5 stand rejected under 35 U.S.C. § 103 as being
unpatentable over the APA in view of Lindmayer or Bachhuber.
The Examiner states (Final Rejection, pages 2-3):
The admitted prior art shows that an IC can be configured
as a receiver to receive and store access codes. The IC
can also be configured as a transmitter to transmit
codes. Both Lindmayer and Bachhuber teach denying access
(erasing codes) based upon the security procedure desired
to prevent unauthorized access to the code. Therefore,
it would have been obvious to one of ordinary skill in
the art at the time of the invention to have utilized the
prevention technique taught by either Lindmayer or
Bachhuber to have prevented an unauthorized user from
gaining access to the stored codes in the above
acknowledged prior art system.
