DEFINITION

Classification: 526/135

(under subclass 90) Subject matter wherein the specified material contains a transition metal compound in admixture with at least one nonmetal-containing material having at least one atom of nitrogen, phosphorus, oxygen, sulfur, selenium, tellurium, or halogen.

(1) Note. Nitrogen gas, per se, is not a basis for classification herein. Such claims are classified elsewhere on some other basis.

(2) Note. Patents which disclose air but do not specifically claim air as a needed component of the composition are excluded herefrom and will be classified elsewhere on some other basis.
