The EPO joined DAS on November 1, 2018 (blog article). At the time, EPO’s participation as a Depositing Office was limited to patent applications that had been filed as national (regional) applications in EPO. From the outset, however, EPO had said that eventually it would also become a Depositing Office with respect to applications filed in RO/EP. Now this welcome development is that RO/EP will be a Depositing Office in DAS from April 1, 2019.
