Appeal No. 1997-2681
Application No. 08/211,414
Claim 1
The Examiner reasons on page 5 of the Answer that APA
(Appellant’s Figure 1) teaches the claimed invention except
that the second filter (14), for information data, is not a
plurality of filters. The Examiner notes that filter
selection control means (15) is substantially taught since it
is responsive to the outputs of all filters (although plural
data information filters are missing) to allow the appropriate
filter to be active. To meet the claimed plurality of
filters, the Examiner cites Fischler, Figure 2, noting that a
zone code (18) is used to select an information data filter
(31-34) dependent on the selected zone to be reproduced. On
page 6 of the Answer, the Examiner notes that Fischler does
not teach selecting a data filter by recognizing the frequency
band in use in the picked up signal. To fulfill this
requirement, the Examiner cites Abbott’s filter 48 in Figure
4. The Examiner points out that Abbott’s filter 48 is adapted
to the zone [frequency] selected on the disk by recognition of
the incoming data stream (i.e., picked up signal). Thus, the
Examiner explains, it would have been obvious to one of
ordinary skill in the art at the time of invention to have
