The Priority Document Access Service (DAS) offers a simple and secure digital alternative to filing paper copies of priority documents with multiple patent offices. This service is administered by the International Bureau of the World Intellectual Property Organization (WIPO).
Through the service a patent applicant claiming priority can have an electronic certified copy of their original application included in a secure digital library. This allows participating offices to access the document and removes the need to separately provide the document to each patent office in which a patent application is filed.
Participation in the service is voluntary for both patent offices and applicants. Priority documents can still be supplied to the International Bureau using other means (such as mail or fax). The International Bureau can also ask us to supply certified copies of priority documents.
How the Priority Document Access Service works
If your priority document was filed in Australia (as either a provisional, standard or innovation specification), the process for using DAS includes the following steps:
- You must submit a request for us to send a certified copy of your priority document to WIPO's digital library.
- Following receipt of the request, we will create a certified copy of the priority document and electronically transfer it to WIPO via a secure data exchange.
- The document will be held by WIPO in a secure database. WIPO will acknowledge receipt of the document by supplying you with a unique access code.
- Use the access code to authorise participating offices to access the priority document.
Where a patent application is filed in Australia (and relies on foreign priority) there is no requirement to provide a certified copy of a foreign priority document, unless it is requested by us. However, if we later request access to the document, you will be able to meet this obligation by advising us that the priority document is available from the DAS.
Further information on using DAS for PCT applications can be found on WIPO’s web site.
The standard fee for creating a certified copy of a priority document will still apply when using DAS. However, by using this service applicants may not need to order and pay for multiple copies of the one priority document.
We do not charge any additional fees for sending the priority document to, or retrieving it from, WIPO's digital library using DAS.
