When you register a design, you identify the product in which your design is incorporated or to which it is applied. The Locarno Classification helps you assign that product to the appropriate class and subclass.
The classification consists of 32 main classes, listed below. It serves an administrative purpose and does not determine the scope of protection for your design.
Based on the 15th edition of the Locarno Classification (LOC 15), effective January 1, 2025. Last checked on October 27, 2026.
