electrodes and thereby generate an electric discharge between
said electrodes;
a dielectric arranged between said electrodes; and
a gas flow passage including an inlet port for supplying a
material gas into said gas flow space, and including an outlet
port for discharging the material gas from said gas flow space,
said gas flow passage being arranged so that the material gas
flows through said gas flow space in a direction transverse to a
longitudinal direction of said parallel grooves.
In the rejection of the appealed claims, the examiner relies

Appellants' claimed invention is directed to an ozone
generator comprising a pair of electrodes in spaced apart
relationship in order to form a space for gas flow therebetween.
At least one of the electrodes has a plurality of parallel
grooves, and the gas flow passage includes inlet and outlet ports
which allows for the gas to flow in a direction transverse to the
longitudinal direction of the parallel grooves. According to
appellants, unlike in the prior art, the present generator
provides for the gas to flow over the ridge portions of the
grooves "where a high density of discharge will be located during
