DEFINITION

Classification: 117/79

Unusable portion contains a metal atom (e.g., diamond or CBN growth in metal solvent):

(under subclass 78) Subject matter in which the unusable residual portion of the precursor* contains free metal*, metal* alloy, or intermetallic compound.

(1) Note. Although Class 117 is proper for original placement of single-crystal* diamond making, a mandatory search and cross-reference is found in Class 423, subclass 446, which is the locus for all diamond making processes (other the than coating processes for Class 427) and products, whether or not a chemical reaction is involved.
