Overview of Patent Registration in Latvia
When considering patent protection for biopharmaceutical inventions in Latvia, it is crucial to understand the overall process and requirements for patent registration. The Latvian Patent Office is responsible for handling patent applications, and the process involves several key steps, including formal and substantive examinations[5].
Patentability Criteria
For a biopharmaceutical invention to be patentable in Latvia, it must meet specific criteria:
Novelty
The invention must be new and not publicly disclosed before the filing date, except for a 6-month novelty grace period if the disclosure occurs at an international exhibition or by third parties in bad faith[1].
Industrial Applicability
The invention must be capable of being used in an industry. This criterion is verified during the substantive examination phase[5].
Inventive Step
Although not explicitly examined by the Latvian Patent Office during the substantive examination, the inventive step is a critical aspect of patentability. Applicants must ensure their invention is not obvious to a person skilled in the art[5].
Formal Examination
The formal examination is the initial step after filing the patent application. The Latvian Patent Office checks if all required documents are submitted, including the applicant's and inventor's names, addresses, and citizenships, as well as the specification with claims, abstract, and drawings. A Power of Attorney and a certified copy of the priority document (if priority is claimed) must also be provided within specified timeframes[1].
Substantive Examination
During the substantive examination, the Patent Office verifies if the invention corresponds to the requirements of industrial application, unity of the invention, biotechnological invention requirements, claim formatting rules, sufficiency, and added matter. However, the examination does not include assessing novelty, inventive step, and industrial application in detail[5].
Scope of Claims
For biopharmaceutical patents, the scope of claims is critical. In Latvia, claims must be clear and concise, and they must relate to the invention described in the specification. Here are some key points:
Claim Formats
Claims can be formatted to cover the use of a product for a specific purpose, but they must adhere to specific rules. For example, claims related to the use of a known product for a new medical purpose can be accepted if they are properly formulated, such as "use of X for the treatment of Y"[3].
Second Medical Use Inventions
Latvian patent law, similar to other jurisdictions, allows for the patenting of new medical uses of known products. However, the claims must be carefully drafted to focus on the new use rather than the product itself[3].
Enforceability of Patents
Validity Term
Patents in Latvia are valid for 20 years from the filing date. For pharmaceutical and agrochemical patents, an additional 5-year extension can be obtained through a Supplementary Protection Certificate (SPC)[1].
Court Proceedings
Patents issued in Latvia can be appealed in court if there are disputes over their validity or infringement. Foreign applicants must be represented by a registered Latvian patent attorney in such proceedings[1].
Compliance with Competition Law
Biopharmaceutical companies operating in Latvia must also comply with competition law. Recent developments in the pharmaceutical sector highlight the importance of adhering to competition rules to avoid fines and mandatory obligations. For instance, agreements that restrict competition, such as those on compensatory drug markups, can lead to significant penalties[2].
Representation and Filing Requirements
Foreign applicants must be represented by a registered Latvian patent attorney when filing patent applications. The application must include all necessary documentation, such as the Power of Attorney, which can be provided within three months from the application filing date[1].
Publication and Registration
After a positive formal examination, the patent application is published within 18 months from the filing date or the first earlier priority date. Once the substantive examination is completed and the state fee is paid, the patent is registered in the State Patent Register, and a notification is published in the Official Gazette of the Patent Office[5].
Opposition and Appeals
Third parties can oppose the grant of a patent within nine months from the publication date, claiming that the invention lacks novelty. The opposition process involves a state fee and can lead to the revocation of the patent if the opposition is successful[5].
International and European Patent Considerations
While Latvia does not allow entry into the national phase of a PCT application, applicants can consider European patent options, including the new Unitary Patent system. The Unitary Patent provides uniform protection across EU member states, but it does not replace national or traditional European patents[4].
Key Takeaways

- Enforceability: Patents are valid for 20 years, with possible extensions for pharmaceutical and agrochemical patents.
- Compliance: Adherence to competition law is crucial to avoid penalties.
- Representation: Foreign applicants must be represented by a registered Latvian patent attorney.
- Publication and Registration: Patents are published and registered after successful examinations and payment of fees.
