Appeal No. 97-2982 Page 10
Application No. 08/219,554
to connect to the same initiator and request status
information on the same target, that information
would not be available. Thus, the prior art system
of using one initiator for multiple processors is
disadvantageous in that if one processor receives
and subsequently clears all target status
information, other processors connected to that
initiator are unaware of any changes that may have
been made in the target's status. (Spec. at 3.)
Thus, a computer in ANSI cannot clear ATTENTION DATA without
disturbing the same ATTENTION DATA for any other computer as
claimed.
For the foregoing reasons, the examiner failed to show
that Fischer and ANSI teach or would have suggested clearing
of ATTENTION DATA as in independent claim 1 and its dependent
claims 2 through 5. Therefore, we find the examiner’s
rejection does not amount to a prima facie case of
obviousness. Because the examiner has not established a prima
facie case, the rejection of claims 1 through 5 over Fischer
in view of ANSI is improper. Therefore, we reverse the
rejection of the claims under 35 U.S.C. § 103.
