on cache capacities of interest (col. 6, lines 66-68). The
equivalence classes have similar collected access operation
statistics. Appellants do not argue this limitation.
As to the limitation of "effectively applying a different
fileserver buffer management policy to files in each of said
fileset categories," the Examiner concludes that using the
same replacement algorithm (e.g., LRU) for different
partitions in Mattson is applying a different buffer
management policy as disclosed at pages 5-6 of the
specification (FR3). Appellants admit that "the Examiner is
correct that a partitioning of a cache into two or more
partitions and the storing of separate file sets in each cache
partition does apply a different buffer management policy to
each of the file sets stored in the separate cache partitions"
(Br8). Appellants argue (Br10): "In Claim 1, the different
buffer management policies correspond with different ranges of
read/write ratios and the buffer management policy assigned to
each file is the buffer management policy that corresponds to
the range of read/write ratios covering the read/write ratio
of that file. An equivalent limitation may be found in
Claim 9." Claim 9 is broader than claim 1 and does not
