line 3). The transponder is coupled to a changeable memory and,
in response to an interrogation signal code, data can be written
into or read from the memory (col. 3, lines 32-36). The
transponder can be miniaturized into, for example, the size of a
credit card (col. 4, lines 22-25), and can be placed on many
different objects (col. 2, lines 55-56). The exemplified use of
the transponder system is for paying tolls at automotive vehicle
toll booths (col. 3, lines 41-59).
The examiner argues that it would have been obvious to one
of ordinary skill in the art replace Purcell’s integrated circuit
memory element with Cardullo’s transponder and RF transceiver “to
provide a highly economical and reliable interrogation system
applicable under all environmental conditions which requires no
internal power source, is physically small in size and can be
placed on many different objects as taught by column 2, line 45 -
column 3, line 2 of Cardullo et al. and as suggested by column 9,
lines 41-50 of Purcell et al. regarding a similar transponder
placed on a print roll” (answer, pages 4-5). The accuracy and
reliability of the transponder system under all environmental
conditions indicated by Cardullo (col. 2, lines 64-67) clearly is
desirable in the exemplified use of the system for collecting
highway tolls. The examiner, however, has not provided evidence
