WIPO Digital Access Service for Priority Documents

It is recalled that, by using the WIPO Digital Access Service for Priority Documents (DAS), a PCT applicant can request the International Bureau (IB) to retrieve a copy of an earlier application from DAS for use as a priority document, instead of providing or arranging for the provision of a certified copy.  Note that in order to be able to make use of the DAS service, it is the office with which the earlier application was filed that needs to be a DAS depositing Office, and not necessarily the receiving Office with which the international application is filed.

Netherlands Patent Office

The Netherlands Patent Office has notified the IB that, with effect from 1 June 2018, it will commence operation as both a depositing and an accessing Office of DAS. 

As a depositing Office, it will deposit all national and international patent applications filed on or after 1 June 2018 which the applicant specifically requests be made available to DAS.  As an accessing Office, it will recognize priority documents available to it through DAS for the purposes of any application for which the time limit for furnishing the priority document has not expired by 1 June 2018.
