Term of protection and validity

An industrial model patent shall be effective for five years from the date of the industrial model application filing; the patent term may be extended by the patent authority upon a petition of a patentee, but no more than five years.

A petition on prolongation of a term of an industrial model patent  shall be filed with the patent authority before expiration of the patent. The patent fee payment for keeping a patent in force for each payable expired year and the subsequent year, which has begun on the date of decision on grant of a patent, shall be performed simultaneously with a patent fee payment for grant of a patent within two months from the date the applicant receives the decision to grant the patent.

The patent fee for keeping a patent in force shall be paid for each year of the patent term starting from the first year counting from the date of filing of an application with the patent authority.

The patent fee for each subsequent year of effect of a patent shall be paid within the current paid year of effect of the patent. The patent fee for any year of effect of a patent may be paid within six months from the date of subsequent unpaid year of effect of the patent. In such case, the patent fee rate will be increased by 50 per cent.

If the effect of a patent has been terminated due to failure to pay the patent fee for keeping the patent in force in due time, and the patent term has not expired, then, upon petition of the patent proprietor, the effect of such patent may be restored on condition of payment of arrears on the patent fee and the patent fee for restoration of the patent effect in the established amount.
