and I/0 adaptors with Queue Descriptors for each I/0
device in the Mailboxes (see columns 5-7) for
storing ATTENTION DATA (see Module Attention and
Device Attention on columns 7-8 and 29, line 45 et
seq.) when a UNIT ATTENTION condition exists. The
commands to be sent and received between the hosts
and targets such as ATTENTION DATA, CHECK CONDITION,
giving a warning, resending the warning, REQUEST
SENSE, getting the sense key, checking UNIT
ATTENTION are SCSI standard commands which are
followed by Fischer as shown on column 24, lines 53-
54. Fischer teaches the basic structure of the
inventive system fo [sic, for] claims 1-10, but
doesn't provide all of the details of SCSI operation
attributed to the various elements as claimed by the
Applicant. Fischer describes that when the
controller detects an error during a device
operation the Queue Descriptor which is in memory
for each decvice [sic] is checked as shown on column
32, lines 42-64. Fischer describes that EACH HOST
has memory allocated for EACH TARGET for SCSI
commands. The commands to be sent and received
between the hosts and targets such as ATTENTION
DATA, CHECK CONDITION, giving a warning, resending
the warning, REQUEST SENSE, getting the sense key,
checking UNIT ATTENTION are SCSI standard commands.
(Id.)
The examiner also opines that the claimed memory structure
“would appear to be equivalent to the structure disclosed by
Fischer at column 2, lines 44-48.” (Supplemental Examiner’s
Answer at 2.) The examiner reasons, “[s]ince Fischer suggests
SCSI operation in accordance with the ANSI standard, the
artisan would have ben [sic, been] motivated to implement SCSI
