7). Appellant points out that although Sugiyama increases or
decreases the number of taps of an individual sub-filter, there
are no details provided as to how such change in their numbers is
performed (brief, page 7). Finally, Appellant argues that
neither reference teaches or suggests that system resources are
selectively allocated for storing the weighting coefficients
(brief, page 8). Appellant adds that the X-register 60 of Horna,
as relied on by the Examiner, is a shift register for storing
input samples involving no selectivity even in storing the
samples and differs from the claimed selective allocation of
system resources (id.). Furthermore, Appellant argues that even
if the Examiner meant to refer to H-register 65a of Horna or
substitute the registers with random access memory, there still
would have been no teaching related to dynamically varying the
size of the storage element (reply brief, page 2).
In response to Appellant’s arguments, the Examiner points to
column 4, lines 37-43 of Sugiyama for teaching a step of
selectively increasing or decreasing the number of taps used by
the adaptive filter (answer, pages 10 & 11). Additionally, the
Examiner repeats the discussion of Horna related to register 60
in figure 4 and concludes that the references “disclosed the
