recompression network when a subsampling network is activated, a
feature set forth in each of the appealed independent claims 1
and 6.
After reviewing the Canfield reference in light of the
arguments of record, we are in general agreement with Appellants’
position as stated in the Brief. Initially, we are in agreement
with Appellants that the Examiner’s attempt (Answer, page 4) to
draw a correspondence between Canfield’s variable length and
fixed length compressors (Canfield, Figure 3) and the claimed
recompression and subsampling networks is without merit. While
we do not dispute the Examiner’s assertion that both types of
networks are ultimately directed to the goal of achieving data
reduction, this does not necessarily lead to the conclusion that
they have the same structure or operate in the same manner to
produce the data reduction result.
We recognize that the Examiner at page 5 of the Answer, has
expanded the stated position of obviousness by referring to a
portion of Canfield (column 2, lines 24-28) which discloses a
dual mode data reduction network in which data recompression and
horizontal decimation (subsampling) are selectively employed.
According to the Examiner (Answer, page 5), this “selective
employment” disclosure can be interpreted as suggesting that
