Appeal No. 96-3156
Application 08/304,333
communication between the master cylinder and the brake, and in a
second mode or position provides modulation of fluid pressure at
the wheel brake while providing a constantly open fluid
communication channel between the master cylinder and the
artificial pedal feel device. Independent claim 7 is similar
except that in the second position, the valve provides modulation
of fluid pressure at the wheel brake while the master cylinder is
out of communication with the brake.
THE REFERENCES
The references of record relied upon by the examiner in
support of a rejection under 35 U.S.C. § 103 are:

(British Patent Document)
With reference to Figure 1, Steiner, the examiner’s primary
reference, pertains to a fluid brake system similar to
appellants’ system in that in a first default mode the system
operates to provide for unboosted operation of the wheel brakes
(14, 16, 17, 18) by a master cylinder (13), and in a second mode
the system operates to provide for power brake operation of the
wheel brakes. In the unboosted first mode, function control
valve (39) is positioned in the illustrated left hand or “O”
