WIPO Standards

WIPO Standards provide a single, common framework for working with the information contained within industrial property documents.

They cover patents, trademarks, and industrial designs and are used at all stages of the industrial property prosecution process, as well as for data dissemination.


We organize workshops for IP offices, observers, representatives of industry, and other interested parties on various aspects of IP information.

The results of our workshops are presented to the CWS for further consideration.
