Mold & Tool Co. v. Great Lakes Plastics, Inc., supra.
Timewell is directed to a method and apparatus for
electrically conditioning electrode means positioned in an
electrolyte (see col. 2, ll. 21-24). Timewell discloses use of a
saltwater electrolyte with production of hydrogen at the cathode
and relatively little oxygen at the depassivated anode (col. 3,
ll. 28-31; col. 4, ll. 49-66). Pons, as previously discussed, is
directed to the electrolysis of water to produce hydrogen, oxygen
and heat but the examiner has failed to identify any portion of
Pons that teaches the equivalency of aluminum and palladium as
isotopic hydrogen storage cathodes (see the Answer, page 13,
citing page 32 of Pons). Sobieralski is directed to the
production of zinc powder from the electrolysis of lead-
containing zinc halide solutions (abstract; col. 2, ll. 25-32).
The cathode materials disclosed by Sobieralski are taught to be
equivalents since they do “not detrimentally effect the operation
of the process or the properties of the produced zinc to an
