wireless identification device, having a housing 10, a battery
14, and circuitry 12, with a switch 15. Switch 15 controls
whether or not the circuit is connected to the battery, enabling
the device to operate. Since switch 15 enables receiver circuit
81, this allows for user control of when identification is sent.
The examiner employs Froschermeier to show an RF identifier
which utilizes a modulated backscatter system for saving battery
strength and concludes that it would have been obvious to have
utilized the user control switch of Walton in Froschermeier’s
backscatter identifier in order to provide user control over the
battery saving operation of the device. Appellant does not argue
to the contrary.
The examiner employs Kawauchi to show a switch comprising a
button having two thick film conductors, 2A and 2B, an insulative
ring, 7, and a conductive-faced diaphragm, 9, concluding that it
would have been obvious to have used the specific switch of
Kawauchi in the wireless identification device of Walton, to make
an effectively operated switch. Again, appellant does not
dispute this.
Appellant argues only the “push-on/push-off” nature of the
claimed switch, urging that since Walton’s switch is
automatically reset after a predetermined interval, the user
cannot push OFF the switch in Walton. As support for this
