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.
The DAS system is the responsibility of the WIPO IP Office Business Division (IPOBSD), working in coordination with the WIPO PCT Sector for questions relating to the IB as an accessing and depositing office.
