Background
The WIPO Digital Access Service (DAS, also known as the Priority Document Digital Access Service) is a system allowing priority documents to be exchanged directly between Offices instead of requiring the applicant to request and forward certified copies of patent applications to support priority claims.
The system provides for applicants and offices to securely exchange documents, meeting the needs of the Paris Convention for certification.
