Appeal No. 95-1655
Application 07/788,829
other decoder-drivers 5 and 6 operate to drive the LEDs indicated
in the figure. These decoder-drivers 5 and 6 essentially split
the bit output from the buffer register 3 in an effort to
respectively drive the LEDs 500 etc. and 600 etc. respectively.
Considering the collective teachings of the references, we
find there is no teaching in the prior art relied upon to cause
an 8-bit microprocessor to operate in a 4-bit output mode or some
form of a two step 4-bit output mode, such that the data output
from such a microprocessor may be split or paired between
respective control devices. Because Nishida has no such
microprocessor, the suggestion to do so to meet the above noted
language of each independent claim cannot come from Nishida, and
it is not present in the admitted prior art either. Thus, we
conclude that the collective teachings of the prior art, even if
properly combinable within 35 U.S.C. § 103, would not have led
the artisan to the subject matter of the claims on appeal.
