Appeal No. 96-0338
Application 08/095,179
Although we do not ascribe to appellants' views that
Kroschel actually teaches away from the claimed cepstrum
analysis means, we do agree with appellants' overall view that
cepstral coding and cepstral coefficients in Kroschel are
taught in the reference to apply only to word recognition
circuits as just outlined. We are not persuaded by the
examiner's arguments nor do we find any evidence among
Kroschel's teachings as a whole that it would have been
obvious to the artisan to have applied the cepstral coding
teachings specific only to word recognition methods to
substitute for the specified noise reduction methods at pages
84 and 85 of Kroschel's article.
