As agreed by the WIPO Member States during the 13th edition of the Committee on WIPO Standards (CWS), the transition period for the exchange of priority documents using Standard ST.92, will start on July 1st, 2026 and will end on June 30th, 2028.
The WIPO Digital Access Service (DAS) is an electronic system allowing priority documents and similar documents to be securely exchanged between participating intellectual property (IP) offices. The system enables applicants and offices to meet the requirements of the Paris Convention for certification in an electronic environment.
The Service is intended for use with documents related to patents, industrial designs and trademarks.
