data independently (autonomously) from the part of the memory
controller that reads out data for the CPU. Therefore, the
issue is whether it would have been obvious to use autonomous
scrubbing means to provide data to a virus signature checking
operation.
The Examiner states (EA12): "The examiner's Final
rejection states that it would have been obvious to utilize
the scrubbing means to initially check for soft errors, as
taught by Ryan, and then subsequently check for virus errors,
as taught by Arnold and Watson because it would enable one of
ordinary skill in the art to perform well known scrubbing
operations prior to implementing Arnold's and Watson's
operations, thus allowing soft errors to be detected prior to
any viral detections."
This reasoning does not address the memory scrubber
providing data for virus signature detection. The combination
of Watson and Arnold with the memory scrubber of Ryan would
have suggested a hardware memory scrubber of Ryan that
operates independently from the virus signature detection
process of Arnold and Watson. The Examiner does not point to
any teaching or suggestion for the memory scrubber means
