Eurasian Patent for Inventions

A regional patent route for obtaining one Eurasian patent for an invention effective across the Eurasian Patent Convention member states.

A Eurasian patent application is a key route for obtaining patent protection for an invention across the member states of the Eurasian Patent Convention. One granted Eurasian patent may provide protection in Azerbaijan, Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Turkmenistan.

A single Eurasian application is filed and examined by the Eurasian Patent Office, resulting in one regional patent framework rather than separate national procedures from the outset.

This route is typically used where protection is required across multiple Eurasian jurisdictions and centralised administration is commercially advantageous.

Why Use the Eurasian Route

The Eurasian route is generally chosen where applicants need coordinated patent protection across several Eurasian states through one filing framework and one office.

One Application

Only one Eurasian patent application is filed instead of separate national applications in each member state.

One Patent

One granted Eurasian patent may be effective across all eight contracting states covered by the system.

Centralised Maintenance

Maintenance is handled through the Eurasian Patent Office without separate annual payments in each country.

Russian-Language Filing

Application materials need to be translated into one working language only — Russian.

Accelerated Examination

Accelerated examination may be available and may reduce the timeline to approximately one month.

Stable Regional Framework

The Eurasian system operates through an international organisation independent from political or economic conditions in individual contracting states.

When the Eurasian Route Is Usually Chosen

The Eurasian route is usually considered where an applicant needs protection in several Eurasian jurisdictions and wants to avoid parallel national procedures from the outset.

It may be especially practical for technologies intended for regional manufacturing, distribution, licensing or long-term commercial use across connected Eurasian markets.

The route may also be attractive where centralised prosecution, Russian-language filing practice and unified maintenance through one Eurasian patent attorney are important for portfolio administration.

Important: Where only one country is commercially relevant, direct national filing may still be more appropriate. The Eurasian route should be assessed together with the applicant’s filing geography, budget and commercial plans.

How the Application Can Be Filed

There are two principal routes for filing a Eurasian patent application, depending on the applicant’s jurisdictional position under the Convention.

Direct Filing with the Eurasian Patent Office

Applicants from states that are not members of the Eurasian Patent Convention may file directly with the Eurasian Patent Office.

Filing through a National Patent Office

Applicants from contracting states may file through the national patent office of the relevant member state.

Required Documents

The application package must contain the core patent materials and supporting filing documents required by the Eurasian Patent Office.

Application Materials

The filing set includes the description, claims and abstract. These materials are filed in Russian. The applicant may provide the translation, or translation support may be arranged as part of filing assistance.

Power of Attorney

A power of attorney from the applicant is also required for representation in the procedure.

Procedure

After filing, the Eurasian patent application proceeds through several procedural stages within the Eurasian Patent Office.

Filing Date and Formal Examination

The Office establishes the filing date and carries out formal examination of the application materials.

Search and Substantive Examination

A patent search is performed, followed by substantive examination of the invention.

Decision on Grant or Refusal

Following examination, the Office issues a decision either to grant the Eurasian patent or to refuse the application.

Important: We support the application throughout the full prosecution process and inform the client in advance about expected costs and procedural steps.

Searches and Filing Preparation

Preliminary patent searches may be important before filing a Eurasian patent application because substantive examination evaluates novelty, inventive step and industrial applicability against the worldwide state of the art.

Search results may help identify close prior art, clarify essential technical features, prepare claim strategy and assess whether the proposed invention should be further developed before filing.

For PCT-based strategies, search and examination materials from the international phase may also be considered when planning entry into the Eurasian regional phase.

Important: A preliminary search does not guarantee grant of a Eurasian patent, but it may help reduce uncertainty and prepare a stronger application strategy.

After Grant

Once a positive decision has been issued, several final steps must be completed before the granted patent is issued to the applicant.

Payment of the Grant Fee

The official fee for patent issuance must be paid.

Preparation of Final Materials

Application materials corrected during examination are prepared in their final form.

Patent Issuance

The granted Eurasian patent is issued and forwarded to the applicant.

Maintenance

Maintenance of a Eurasian patent begins annually from the 4th year after filing.

We monitor deadlines, remind clients in advance and calculate the relevant maintenance fees as part of ongoing portfolio support.
