According to Russian law, the grounds for invalidating an invention (utility model) patent in Russia include the following:
An invalidation action can be brought during the term of the patent’s validity by any person who has become aware of the above patent law violations.
Moreover, a cancellation action can also be filed after the expiration of the term of the patent by any person having legal interest in invalidating the patent.
A legal action according to item 5 above should be brought to court; in all other cases, an opposition against the patent grant is filed with the Russian PTO’s Chamber for Patent Disputes.
The Rospatent decision is appealable to the Intellectual Property Court and, further on, to the Presidium of the same Court as a cassation instance.
A Eurasian patent can be challenged in any member state in accordance with this state’s national procedure after the expiration of the 6-month period provided for filing a notice of opposition with the Eurasian Patent Office (administrative revocation of the Eurasian patent).
Sojuzpatent’s patent attorneys and litigation lawyers represent the client’s interests before the Chamber for Patent Disputes, the Eurasian Patent Office, and Russian courts, including the Intellectual Property Court and the Supreme Court of the Russian Federation.
