Outline of the DAS

1. Multilateral Electronic Exchange of Priority Documents

The DAS offered by the WIPO has been available since April 2009, which allows electronic exchange of priority documents among multiple countries. This aims to simplify the procedures for filing applications claiming priority under the Paris Convention with several offices and organizations.

Priority documents are provided by an Office of First Filing electronically to Offices of Second Filing through the DAS when applicants undertake the prescribed procedures at the time of filing an application with participating offices and organizations in the DAS. Therefore, the applicant does not need to submit priority documents in paper form to the Offices of Second Filing.

2. Outline of the DAS

An applicant, who has filed an application with a DAS participating office and wishes to take advantage of the DAS, must provide the Office of Second Filing with Access Code (issued by the Office of First Filing) and other information. No further steps will be required for the applicant. A priority document will be transmitted from the Office of First Filing to the Office of Second Filing via the DAS.
