The Locarno Agreement, concluded at Locarno in 1968 and amended in 1979, establishes a classification for industrial designs (the Locarno Classification).
The competent offices of the Contracting States must indicate in official documents and in any publication they issue in respect of the deposit or registration of industrial designs the numbers of the classes and subclasses of the Classification to which the goods incorporating the designs belong.
The Locarno Agreement created a Union, which has an Assembly. Every State that is a member of the Union is a member of the Assembly. Among the most important tasks of the Assembly is the adoption of the biennial program and budget of the Union.
The Agreement also set up a Committee of Experts in which all members of the Union are represented. The main task of the Committee is the periodical revision of the Classification.
The Agreement is open to States party to the Paris Convention for the Protection of Industrial Property (1883). Instruments of ratification or accession must be deposited with the Director General of WIPO.
