DEFINITION

Classification: 502/326

Of platinum group metal and of iron group (i.e., Ru, Rh, Pd, Os, Ir, or Pt and Fe, Co or Ni):

(under subclass 325) Composition in which there is at least one metal, oxide, or hydroxide from each of the iron group and the platinum group.

(1) Note. To be classifiable here, a patent must claim for example iron oxide and platinum; a mixture of iron and nickel or a mixture of rhodium and palladium are not proper for this subclass.
