Appeal No. 1998-2664
Application No. 08/426,426
The examiner reasons through the noted pages of Deller as applied to the claims
on appeal, but recognizes that Deller does not teach the implementation of line spectral
coding with the use of a codebook.
As to this feature, the examiner asserts that a codebook implementation of line
spectrum frequencies (LSFs) is old and well known in the art of speech processing, since
such codebooks have provided an appropriate set of patterns which help minimize overall
distortion. For their part, appellants' position at page 3 of their brief merely urges the
reversal of the rejection of the claims on appeal because there is no suggestion of the use
of a codebook in Deller. It is noted that the feature of this codebook is relied upon as a
feature in each of independent claims 1, 7 and 10 on appeal.
As rightly noted by the examiner at page 5 of the answer, appellants have failed to
properly address the examiner's contention in the final rejection that such codebook
implementation of line LSFs is old and well known in the art of speech processing. On the
basis of the absence of any position by appellants as to this assertion by the examiner, we
take it as established. Inasmuch as this is the only argued feature with respect to
independent claims 1 and 10 on appeal, we sustain the rejection of these claims and
dependent claims 2 and 6 which have not been argued by appellants.
