What is the International Classification for Industrial Designs?

In 1968, the Locarno Agreement was signed by members of the Paris Convention to establish an international classification system for industrial designs, known as the Locarno Classification. This system is designed to set standards for the classification of industrial designs, using a two-level structure consisting of classes and subclasses in Arabic numeral order. The Locarno Classification comprises 32 classes, ranging from foodstuffs to graphic symbols and logos, surface patterns, and ornamentation. Each class is further divided into subclasses, and this system provides a useful framework for organizing and searching industrial design documents.
