International Class Law and Legal Definition

International class is an internationally agreed system in which international classes are assigned to trademarked goods and services. "Goods" are grouped into 34 classes. The classes are generally sorted by the material from which the goods are made and the use to which the goods are put. "Services" are grouped into 11 classes that are generally sorted by the type of service provided. The purpose of the system is to enable trademarks to be searched and compared for possible conflicts. In the U.S., international classes are assigned to a mark under the International Classification of Goods and Services (Nice Agreement) since 1973.
