Eurasian Patent

  • General Information
  • Filing procedure
  • Remarks


The Eurasian Patent Convention entered into force on August 12, 1995, after ratification by four countries. The Convention allows the filing of one patent application in the Russian language with an automatic designation of all Member States.

The following nine States have so far ratified the convention: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova (denunciation of the Convention with effect from April 26, 2012), the Federation of Russia, Tajikistan, Turkmenistan.

After the grant of a Eurasian Patent, the patentee shall indicate in which Member States he desires to maintain the patent. Fees are then due with respect to each Member State. As of January 1, 1996, it is possible to designate the Eurasian regional phase in a PCT application, (as for the EP-regional phase), the designation including all countries for which the Convention is in force at that point in time. The Eurasian Patent Office also accepts direct applications. The Office is located in Moscow where a complete examination is carried out, including grant and issuance of a single patent document. After-grant aspects (validity, infringement, etc.) are handled by the national authorities.
