A diplomatic conference, attended by countries which were members of the Paris Convention for the Protection of Industrial Property, was held in Locarno, Switzerland, and adopted the Locarno Agreement on October 6, 1968. This established an International Classification for Industrial Designs (Locarno Classification).
- a list of classes and sub-classes;
- an alphabetical list of goods which constitute industrial designs, with an indication of the classes and sub-classes into which they fall;
- explanatory notes.
The original list of classes and subclasses was attached to the Locarno Agreement when it was adopted.
The Locarno Classification has been revised several times by a committee of experts.
The twelfth edition was published in June 2018 and came into force on January 1, 2019. It replaces the previous editions.
There is more about the Locarno Classification on the World Intellectual Property Organization (WIPO)
website.
