Old U.S. Trademark Classes

Trademark applications filed at the United States Patent and Trademark Office (USPTO) before September 1, 1973, were originally categorized according to a national classification system. International classes have since been assigned to all such registered marks, but the original U.S. classes are still also included in the database. For applications filed on and after September 1, 1973, a list of corresponding U.S. classes is generated automatically by the USPTO based on the international classes for the registration.
