Appeal No. 97-2879
Application No. 08/507,181
Kawasaki, the portable unit can be a cordless telephone
carried by a person (column 1, lines 14 through 19).
Blonder discloses a wrist-mounted telephone 2 with a
speaker 20 and a microphone 22 that is exposed when the
speaker is pivoted into an operable position (Figures 1 and
2). The wrist-mounted telephone normally operates at radio
frequencies, but Blonder states that “the device is equally
useful with infrared” (column 4, lines 14 through 17).
Appellant has not challenged the examiner’s conclusion
(Answer, page 7) that:
Therefore, it would have been obvious to one of
ordinary skill in the art at the time the invention
was made to substitute infrared transmission for
radio frequency and to provide a wristwatch form
factor for the portable telephone set in Kawasaki
since Blonder explicitly teaches the substitution
and the use of the wristwatch form for a portable
telephone set.
The examiner admits (Answer, page 7) that “Kawasaki does
not teach the transmission of the receiver’s identification
number within the acknowledgment signal transmitted in
response to the hailing message.” For such a missing
teaching, the examiner turns to Stoller. According to the
examiner (Answer, page 7):
