Appeal No. 96-1145
Application 08/203,768
This is an appeal from the examiner’s final rejection of
claims 13-26. Claims 1-11, which are the only other claims
remaining in the application, stand withdrawn from
consideration
by the examiner as being directed toward a nonelected
invention.
THE INVENTION
Appellants’ claimed invention is directed toward a method
for producing diamond crystals on seed particles which are
separated from a carbon source by a plurality of alternating
zones of carbon-rich and carbon-lean metallic solvent
extending from the carbon source to the seed particles. 2
Claim 26 is illustrative and reads as follows:
26. A method of producing diamond crystals which
includes the steps of placing a reaction vessel in the
reaction zone of a high temperature/high pressure apparatus,
wherein said reaction vessel includes a reaction volume and a
2Appellants state that the carbon-rich zones typically
contain about 3.5-5 wt% carbon, and the carbon-lean zones
typically contain substantially no carbon, i.e., less than
400 ppm carbon, and that the carbon may be dissolved in the
metallic solvent or admixed therewith (specification, page 4).
