DEFINITION

Classification: 428/675

(under subclass 674) Subject matter in which the copper-base component is adjacent a component which contains 40 percent or more of cobalt, copper, or nickel.

(1) Note. Where the adjacent component contains less than 40 percent cobalt or copper, but the combination of these two metals is 40 percent or more, the patent is classified in this subclass (675); where this same situation exists with regard to the combination of copper with nickel, see subclass 671.

(2) Note. Patents classified herein are not cross-referenced to subclasses 668, 678, or 680 on the basis of the Cu/Co-Ni interface.
