Appeal No.1996-3237
Application 08/266,431
16 of Carbine performs a comparison between circuit states and
expected circuit states, it does not perform the claimed
comparison of circuit states to each other at two different
points in time. Thus, Carbine does not teach or suggest the
claimed comparison, and the examiner has not addressed the
question of why it would have been obvious to compare two
states of Carbine’s circuit with each other.
It should be noted that the plurality of circuit
states output in Carbine are intended to be compared to a
corresponding plurality of expected circuit states so that the
exact point at which an error first occurred can be
pinpointed. Although the circuit of Carbine will detect an
error caused by a circuit being locked in a stuck state, it
does not detect this type of error in the manner recited in
the claimed invention.
Since each of claims 6-9 recites that the comparison
is between two different states of the circuit under test, and
since the examiner has not addressed this difference between
the claimed invention and the teachings of Carbine, the
