Appeal No. 1997-2681
Application No. 08/211,414
We agree with the Examiner. The APA clearly teaches
selection between filters based upon the reproduced signal
from the disk wherein the servo data filter or the information
data filter is selected to be active. Thus, the APA clearly
teaches the filter control means is responsive to the outputs
of the different filter means. Appellant implies that claim 2
requires the filter to be programmed in response to the
outputs of the filters. We find that claim 2 recites no such
requirement. Claim 2 recites that “said second filter means
includes means for programming the band of said second filter
means to a frequency band corresponding to the frequency band
of said information data in said picked up signal.” (emphasis
added). As the Examiner points out, this requirement is met
by Abbott wherein it states filter “40 is programmed so that
it is optimized for the data transfer rate of the selected
data zone 70 from within which the
transducer head 26 is reading data.” (column 10, lines 19-22).
We find this clearly meets the corresponding to language of
claim 2.
Accordingly, we will sustain the Examiner’s rejection of
claim 2.
