Lithuanian IP: Key Highlights
Lithuania is a member of the World Intellectual Property Organization and a party to key international IP treaties, including the Paris Convention, the Patent Cooperation Treaty, the Madrid System, the Hague Agreement, and the Berne Convention. As an EU Member State, Lithuania provides a modern and harmonized IP framework, offering protection at both national and EU levels.
- EU-Wide Protection Options: Rights holders can benefit from European Union trademarks (EUTM), Community designs, and European patents via EPO, allowing streamlined protection across the EU through unified procedures.
- Dedicated IP Institutions: The State Patent Bureau of the Republic of Lithuania (VPB) manages patents, trademarks, and industrial designs, while IP disputes are addressed by Vilnius Regional Court and the Appeals Division of VPB.
- Digital and Accessible IP Services: Lithuania offers fully electronic filing, WIPO-integrated Madrid e-filing, public online registers, and digital case management systems, ensuring transparency, efficiency, and ease of access for both domestic and international applicants.

-
What are the official fees for IP registration in Lithuania?Official fees vary depending on the type of IP, number of classes (for trademarks), and whether expedited procedures are used. Fee schedules are published by the Lithuanian Patent Office. For a detailed calculation of costs for your specific intellectual property, please contact our specialists.
-
Do foreign applicants need a local patent attorney to file IP in Lithuania?Yes. Non-resident applicants must appoint a local representative or patent attorney to file patents, trademarks, or industrial designs, and to receive official communications from the Lithuanian Patent Office.

-
Are copyright and related rights protected automatically in Lithuania?Copyright and related rights are automatically protected in Lithuania as soon as qualifying works exist in a tangible form. While no formal registration is required, unofficial registration or deposit procedures can be used to establish evidence of authorship and creation date in enforcement or disputes.

Does a European patent provide protection in Lithuania?Yes. A European patent can be validated in Lithuania through the Lithuanian Patent Office. Validation requires payment of national fees, submission of the necessary documents including Lithuanian translations, and compliance with formal national procedures.
-
Is it mandatory to use a registered trademark in Lithuania?No. Lithuanian law does not require immediate use of a registered trademark. However, if a trademark is not used continuously for five years after registration, it may be subject to cancellation for non-use upon request of an interested party.
-
Can customs authorities enforce IP rights at the border in Lithuania?Yes. As an EU Member State, Lithuania applies EU customs regulations, allowing authorities to suspend goods suspected of infringing registered IP rights — including trademarks, designs, patents, and copyrights — at the border.
