standard power (col. 7, lines 50-60).
This is the opposite from that of the
subject invention. In fact, there is
no incentive for the Boyles et al.
system to transmit the secure data at
a reduced power. [brief, page 6].
We do not agree that the teachings of Boyles are as limited as
argued by appellant.
Boyles teaches one embodiment in which a remote control
transmitter can be adjusted to a substandard or a standard
range of transmission by adjusting the output power level of
the transmitter [column 7, lines 40+]. Boyles further teaches
that this transmitter can be tuned down (power lowered) and
the vehicle armed by standing proximate to the vehicle so that
the [arming] signal does not reach the intercepting equipment
of a thief [column 8, lines 5-9]. In our view, the artisan
would have understood these passages of Boyles to suggest the
obviousness of transmitting either secure data or operational
commands at either a high output power level or a low output
power level depending on the level of security desired by the
user. Thus, we do not agree with appellant’s argument that
there is no incentive in Boyles to transmit secure data at a
