B. The subject matter of the invention
3. The application is entitled "Electronic ballast for
fluorescent lamps". (Paper 1 at 1.) The ballast has a
transistor inverter connected in parallel to a rectifier and
center-tapped, series-connected filter capacitors. The lamp
circuit connects the capacitors to the inverter via an inductor.
A fluorescent lamp is connected in parallel with a capacitor,
which is connected in parallel with a resistor. (Paper 1 at 2;
Fig. 1.) Claim 66, reproduced below, is representative of the
claims on appeal.
66. An arrangement comprising:
a DC source operative to provide a DC voltage
at a set of DC terminals;
a ballast circuit connected with the DC
terminals; the ballast circuit having a pair of ballast
terminals which, when connected to a proper load
circuit, will supply a load current to this load
circuit; the ballast circuit being further
