patent practice

A European patent granted by the European Patent Office (EPO) can provide protection in up to 46 countries, including EPO member states, extension, and validation states. Under the London Agreement, the validation process is significantly simplified in certain jurisdictions; for instance, countries such as Germany, France, and Switzerland no longer require a translation of the patent specification to maintain the patent's effect. However, in most other jurisdictions, including Lithuania, specific national validation procedures must be completed within prescribed deadlines to ensure enforceable legal rights.

Validation Procedure

Our company offers the European patent validation service in Lithuania. The deadline for filing the validation request to Lithuanian Patent Office is 3 months from the publication of mention of grant of the European patent in the European Patent Bulletin. Failure to meet this deadline results in the permanent loss of patent rights in Lithuania — the European patent will have no legal effect in this jurisdiction from its filing date, with no possibility of reinstatement.

Validation Requirements

OFFICIAL FEES
Applicants must pay a publication fee to the State Patent Bureau (VPB), calculated based on the specification's length. Renewal fees are due annually. Please note that if a renewal fee is paid after the deadline, a 50% surcharge applies, provided the payment is made within a 6-month grace period.

TRANSLATION
There are also translation requirements for validation of European patent in Lithuania. It is necessary to submit translation of the claims into Lithuanian language to the Patent Office. The Patent Office verifies the conformity of the translation with the original text, and any discrepancies may lead to an Office Action.

LOCAL REPRESENTATION
In accordance with national law, foreign applicants must be represented by a registered Lithuanian patent attorney. Our firm provides full legal support and handles all communication with the State Patent Bureau of the Rebuplic of Lithuania on your behalf.

THE POWER OF ATTORNEY
The Power of Attorney simply signed and stamped by the patent proprietor has to be filed to the Patent Office for further proceedings in respect of European patent validation in Lithuania.

Unitary Patent System in Lithuania

Since the launch of the Unitary Patent (UP) system on June 1, 2023, which currently covers 18 countries including Lithuania, applicants before the European Patent Office (EPO) may opt for unitary protection instead of pursuing traditional national validation. While the Unitary Patent offers significant benefits, it is essential to weigh its strategic impact carefully. Notably, invalidation of a Unitary Patent results in the loss of rights across all 18 participating states simultaneously, rather than on a country-by-country basis. Given these considerations, securing traditional validation in Lithuania remains a highly advisable route for maintaining strong, predictable, localized protection. Our experienced patent team is ready to guide you through the EPO validation process in Lithuania to ensure your rights are fully preserved.
