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 Latvia, 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 Latvia. The deadline for filing the validation request to Latvian 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 Latvia — the European patent will have no legal effect in this jurisdiction from its filing date.

Validation Requirements
OFFICIAL FEES
Validating a European patent in Latvia requires payment of a publication fee (starting from
approximately 90 EUR). To maintain the patent in force, annual renewal fees must be paid to the
Latvian Patent Bureau (Patentu valde).
TRANSLATION
There are also translation requirements for validation of European patent in Latvia. It is necessary
to submit translation of the claims into Latvian 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 Latvian patent
attorney. Our firm provides full legal support and handles all communication with the Latvian Patent
Office on your behalf.
THE POWER OF ATTORNEY
The Power of Attorney is not required for European patent validation in Latvia.
Unitary Patent System in Latvia
Since the launch of the Unitary Patent (UP) system on June 1, 2023, which currently covers 18 countries including Latvia, 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 Latvia 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 Latvia to ensure your rights are fully preserved.
