face of appellant’s objection to the combination, that
“combining hardware with hardware is not of importance with
respect to the rejection” [answer-page 8]. We disagree.
Without some suggestion as to how the structures of Deroo and
Tsang would be combined, there would have been no reason for
the artisan to have done so. It appears to us that appellant
is correct when he contends that the examiner is attempting to
combine abstract “concepts” rather than practical
implementations. From a practical implementation view, there
would have been no reason for the artisan to modify Deroo with
Tsang and no clear direction as to how such a modification
would be made if there were some direction to do so.
Although Tsang does disclose an “on-the-fly” system, there
is no indication that it is even the same type of “on-the-fly”
system envisioned, and claimed, by appellant. Neither Tsang
nor Deroo discloses or suggests data transfers between a first,
SCSI Protocol Controller module and a second buffer memory
module, as claimed. Moreover, Tsang’s on-the-fly error
correction system does not appear to integrity check each word
and data block transferred from a first to a second module
