Appeal No. 1999-0568
Application No. 08/447,594
1 based on an amount of unwritten write request data
cannot be taught or suggested by the applied prior art
because Barajas teaches flushing a memory based on the
amount of invalidation address signals rather than on an
amount of unwritten write request data. These two types
of information are not equivalent, and the examiner has
not presented a valid reason why it would have been
obvious to apply Barajas’ technique with respect to
invalidation address signals to a cache flushing system
based on unwritten write request data. Therefore, we do
not sustain the examiner’s rejection of claim 1 or of any
of the other claims on appeal.
