On 1 January 2017 the Estonian Patent Office joined the WIPO Digital Access Service (DAS), an electronic system for accessing priority documents. The DAS system allows applicants

  • to add the first application document (priority document) to WIPO digital database via Estonian Patent Office as depositing Office;
  • in case a priority exists, when filing an application, to present only an access code to the accessing Office to retrieve a document from WIPO digital database, not the document itself certifying the priority claim.

Service is applicable for national patent applications and utility model registration applications.

Access to priority documents is only available to patent offices participating in WIPO DAS system. The list of participating offices and user requirements can be found here: http://www.wipo.int/das/en/participating_offices.html.

Using the WIPO DAS access service is free of charge for the applicants.

To add a priority document to WIPO DAS database or access it, the applicant has to file a clearly expressed request with the Estonian Patent Office.

The request to add a priority document to WIPO DAS database has to contain the following data.

  1. Name of the applicant
  2. Type of legal protection of the invention (patent or utility model)
  3. Number of priority application
  4. Priority date
  5. Date of filing of the request and signature of the representative

After the document has been registered in WIPO DAS digital database, the Estonian Patent Office sends the access code to the applicant.
