In order to keep the Nice Classification up to date, it is continuously revised and a new edition is published every five years. The revision is carried out by a Committee of Experts set under the Nice Agreement. All States party to the Agreement are members of the Committee of Experts. Part I lists, in alphabetical order, all the goods in one list and all the services in another list. Part II lists, in alphabetical order for each class, the goods or services belonging to that class.
Bilingual versions are also available.
Complete texts of the seventh edition of the Nice Classification have also been prepared and published in other languages by industrial property offices.
