DEFINITION

Classification: 516/97

The material primarily contains elemental platinum group metal, copper, silver, or gold, or compound thereof:

(under subclass 78) Subject matter in which said discontinuous solid phase primarily inorganic* material* primarily contains elemental platinum group metal, copper, silver, or gold, or one or more compound thereof.

(1) Note. "Primarily contains elemental platinum group metal, copper, silver, or gold, or compound thereof" means that 50% or more of the solid inorganic* material*, by weight, volume, molecule, or atom, contains elemental platinum group metal, copper, silver, or gold, or one or more compounds thereof, alone or in combination.
