Appeal No. 2002-1281
Application No. 08/857,711
examiner correctly recognizes that APA teaches everything but
appellants’ improvement over APA.
That improvement is the use of a selectively operable second
transponder having a second code and a fourth coil, wherein the
fourth coil is wrapped around the second transponder. Moreover,
the claims require a relay connected to normally disable the
second transponder and prevent transmission of the second code to
a controller when the passive anti-theft system is in operation,
but to enable the second transponder, by opening terminal ends of
the fourth coil, to allow transmission of the second code to the
controller when the remote starting system is in operation.
In order to provide for this improvement over APA, the
examiner turns to Cantrell for a teaching of using a resistor key
for providing a code to a decoder module, allowing operation of a
vehicle if the correct code is provided. A second resistor key,
located in the vehicle, is used by Cantrell to produce a second
code to the decoder module and this second resistor is
selectively enabled/disabled by a relay in response to a remote
control signal in order to start the vehicle remotely without
activating the security system.
The examiner turns to Nysen for a transponder with a second
antenna or loop placed about the transponder for extending
