Validation/Extension of European Patents

A European patent filed under the European Patent Convention may be extended to/validated in Lithuania within 3 months after the EPO publication of grant of patent.

From the day of entry into force of the European Patent Convention in the Republic of Lithuania, an international patent application designating or electing the Republic of Lithuania pursuant to paragraph 1 of Article 45 of the Patent Cooperation Treaty shall be deemed to be a European patent application.

After Lithuania's joining the EPC applications for EP can be filed through the Lithuanian State Patent Bureau except for extension of PCT to European patents.
