Activities undertaken on behalf of CWS include:


WIPO Standards

The CWS develops WIPO Standards, which provide a single, common framework for working with intellectual property documents. They cover patents, trademarks, and industrial designs at all stages of the intellectual property prosecution process, as well as data dissemination.



We organize trainings from time to time on WIPO Standards and related topics, such as technological developments.  See our Trainings page for more information and a schedule of events.


Workshops & Other Events

We organize workshops for IP offices, observers, representatives of industry, and other interested parties on various aspects of IP information. The results are presented to the CWS for further consideration.


In addition to developing standards, the CWS produces other information resources in related areas.  Among them are:


WIPO Sequence Software Tool

WIPO Sequence is a global software tool for patent applicants to prepare amino acid and nucleotide sequence listings compliant with WIPO Standard ST.26, as part of a national, regional, or international patent application.


Blockchain and IP

Working with the IP community to explore the implications of blockchain technology on IP and find suitable models for blockchain usage in the IP space.


Authority File of published patent documents

The authority file of published patent documents allows interested parties to assess the completeness of available patent documentation from providing IPOs.
