Do I have to prove the legal interest for filing a nullity action against a Russian patent?
According to Russian patent legislation, any person who became aware of violations of patent law can file an invalidation action to the Russian Patent office (or to the court in case the violation relates to the list of the inventors/applicants) during the term of validity of the patent. However, only a person having legal interest in invalidating the patent can file an invalidation request after the expiry of the patent.
