1401.02 International Trademark Classification Adopted
As of September 1, 1973, the international classification of goods and services is the controlling classification used by the United States, and it applies to all applications filed on or after September 1, 1973, and their resulting registrations, for all statutory purposes. See 37 C.F.R. §2.85(a). Unless otherwise indicated, references in this manual to class refer to the international class.
Prior to September 1, 1973, the United States used its own classification of goods and services, which is different from the international classification. The prior United States classification continues to govern for all statutory purposes for trademark applications filed on or before August 31, 1973, and all registrations issued on the basis of an application filed on or before August 31, 1973, unless the owner of the registration amends the registration to adopt international classification. 37 C.F.R. §2.85(b).
If a registration issued under the United States classification system, the owner of the registration may voluntarily amend to reclassify under the international classification system, pursuant to §7(e) of the Trademark Act, 15 U.S.C. §1057(e), if the owner pays the required fee. 37 C.F.R. §§2.6 and 2.85(e)(3). See TMEP §1609.04.
Classification schedules are set forth in Part 6 of the Trademark Rules of Practice. See 37 C.F.R. §6.1 for the international classification schedule for goods and services, 37 C.F.R. §6.2 for the prior United States classification schedule for goods and services, 37 C.F.R. §6.3 for certification marks, and 37 C.F.R. §6.4 for collective membership marks.
