Committee on WIPO Standards (CWS)

The CWS is the collaborative international forum for discussing and reaching agreement on WIPO Standards, including their revision and development. It also deals with other matters relating to industrial property information and documentation.

The Committee was created by WIPO member states at the General Assembly held in 2009 and it currently meets annually.

Our brochure gives you an overview of what WIPO Standards are and how they can help you.

Task forces and e-forums

The CWS establishes Task Forces consisting of policy makers and experts nominated by Committee members and observers to address specific tasks, such as the development of WIPO Standards.

Dedicated e-forums (Wikis) are provided by WIPO to facilitate the discussions of Task Force members.


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.
