Appeal No. 1998-2914
Application 08/510,971
"connected" to the circuit arrangement, (4) how signals from
the reference marks make it possible to perform an
interpolation of the velocity of the sheet in time intervals,
(5) how the processing system performs a registration
operation in order to correct register errors and (6) how and
by what means a steering and regulation device "receives"
inputs from the control circuit. The examiner, however, has
presented no convincing line of reasoning as to why one of
ordinary skill in this art, armed with the appellants'
disclosure, would not be able to make and use the claimed
invention without undue experimentation.
As to contentions (1), (3) and (6), the block diagram of
Figs. 10 and 11 show the required hardware units and we do not
believe that it can be seriously contended that one of
ordinary skill in this art would not be able to provide the
necessary hard-wired circuitry and connections between these
units without undue experimentation. As to contention (2),
the specification adequately explains on page 17 that the
reference and register marks are placed within range of a
single optical scanning device 1 or 2 and on page 24 that:
