Overview of the patent registration procedure in Estonia:
After completion of the filing procedure an Estonian patent application undergoes a formal examination lasting 1 month. On condition that an applicant submits all required documents, a notification about positive result of the formal examination will be issued. Estonian legislation stipulates that the substantive examination is carried out automatically upon publication of the application. At this, no request has to be filed to the Patent Office. If an invention meets the requirements of patentability, the grant decision will be issued. A patent will be issued after payment of the registration fee.

The procedure of the patent registration in Estonia takes from 2 to 3 years.

Foreign applicants must be represented before the Office by a registered Estonian patent attorney.

What is required for filing a patent application in Estonia:

  • filing instructions comprising applicant's and inventor's names, addresses and citizenships;
  • a filing number and a date of a priority application or a PCT application;
  • a specification with claims, abstract and drawings;
  • a copy of the amendments, if any;
  • a Power of Attorney simply signed and stamped by the applicant(s); legalization and notarization are not required unless it is signed by a proxy-holder. The executed PoA may be provided to the Estonian Patent Office within 2 months from the application filing date.

For conventional applications it is necessary to provide a certified copy of a priority document if priority is claimed. It may be provided to the Estonian Patent Office within 16 months from filing an application.
