Answer ... A trademark registration remains in force for 10 years from the date of filing the trademark application. It may be renewed indefinitely every 10 years thereafter. No evidence of use is required for maintenance of a trademark registration.

Answer ... A request to renew the trademark registration and confirmation of payment of the respective renewal fee.

Answer ... Non-use within three years of registration and liquidation of the trademark owner.

Answer ... The Federal Service for Intellectual Property (Rospatent) may not cancel a registration on its own.

Answer ... Any interested party may request the cancellation of a mark for non-use. A non-use action can be brought before the IP Court if the mark has not been used in the three consecutive years preceding the established pre-trial procedure, as outlined below.

Prior to filing a claim for non-use, a party with a legitimate interest must send a letter to the trademark owner asking it either to surrender its trademark rights through Rospatent or to assign the mark at issue to the claimant. The trademark owner has two statutory months to perform either action. If it fails to do so, the claimant has 30 days (following the expiration of the two-month period) to file suit for non-use with the IP Court.

During the trial, the claimant must demonstrate a legitimate interest in the cancellation, while the trademark owner must show use of the mark by disclosing relevant documentary evidence. If the claimant succeeds, the trademark registration will be cancelled from the effective date of the decision of the IP Court.

In addition, a revocation action based on liquidation of a trademark owner can be filed with Rospatent by any party at any point while the trademark remains valid. The revocation action must contain evidence of liquidation of the trademark owner.

Answer ... A decision to revoke a trademark based on liquidation of the trademark owner can be appealed to the IP Court.
