DEFINITION

Classification: 523/511

Organic chalcogen other than metallocarboxylate salt, e.g., diethylene glycol, etc., DNRM:

(under subclass 500) Subject matter wherein the organic DNRM contains a chalcogen atom other than as part of a metallocarboxylate salt, e.g., diethyleneglycol, etc.

(1) Note. Chalcogen for purposes of this subclass is limited to oxygen, selenium, or tellurium.

(2) Note. See the Class 520 Glossary for a definition of the term "metal".
