Appeal No. 95-0907
Application 07/774,757
applicability of messages to be received and transmitted by the
device under test, a combination of Rattan and Wang still would
not satisfy a central feature of the appellant's claimed
invention. Note that claim 1 requires a test sequencing means
for generating and supplying to the device under test a test
sequence of messages, "including messages requesting messages to
be transmitted by the device under test in response indicating
whether functions of predetermined definition are present or
absent in the device under test."
Evidently, the examiner presumed or speculated that Rattan's
system does generate and supply to its peripheral units (device
under test) such a sequence of messages, and did not explain
where in Rattan or Rattan in combination with Wang is such
disclosure or suggestion. In that regard, we do not find in
Rattan, Wang, or a combination thereof a suggestion for sending
messages which request return messages to be sent from the device
under test. Claim 1 further requires that the testing apparatus
analyze the return messages from the device under test for
determining conformity with the standard protocol. The examiner
has not shown where in Rattan arises a suggestion for messages
which are returned "in response" to requesting messages sent from
the testing apparatus.
