PCI [b]us 10 to the PCI Slave State Machine and
Combinatorial logic means 31 (emphasis added).
We find that Cohen’s data lines (10A) are separate from control
lines which are connected between the PCI bus and the access
grant register(PCI-RST#LINE) as well as the logic means on the
PCI bus interface chip(PCI control signal lines). Additionally,
Cohen provides no teachings related to a bus bridge driving 32
address data lines and using one of the 32 lines reserved to
select local buses for enabling the device. We disagree with the
examiner’s characterization of “selected control lines on the PCI
bus” as the address data lines since Cohen’s control lines are
dedicated control lines and are clearly separate from data lines
10A. Therefor, we find that the examiner has not met the burden
of providing a prima facie case of anticipation. Accordingly, we
reverse the rejection of claims 5, 10 and 15 under 35 U.S.C.
§ 102 over Cohen.
