The Mexican trademark regime underwent a key structural transformation with the 2018 reform to the former Industrial Property Law (LPI), which was later ratified and consolidated under the current Federal Law for the Protection of Industrial Property (LFPPI), effective since November 5, 2020. One of the most substantive requirements for trademark owners in Mexico is the mandatory filing of a Declaration of Actual and Effective Use before the Mexican Institute of Industrial Property (IMPI).
1. Statutory Deadlines: When Must the Declaration of Use Be Filed?
Under Article 233 and applicable transitional provisions of the LFPPI, Mexican law imposes two strict, non-extendable procedural moments to declare the actual and effective commercial use of a registered trademark:
- 3-Year Triennial Declaration: Must be filed within 3 calendar months immediately following the third anniversary of the trademark registration grant date.
- 10-Year Decennial Declaration: Must accompany the formal application for trademark registration renewal every 10 years.
2. Statutory Expiration (Caducidad de Pleno Derecho)
3. Remedial Action Plan: What to Do if the Deadline Lapsed?
If no third party has filed an identical mark, run clearance searches on MARCANET/SIGA, submit a new application (de novo), and formally claim the original date of first commercial use in Mexico.
If a third party filed during the interim, initiate formal Opposition or Administrative Nullity proceedings before IMPI by demonstrating senior good-faith commercial use in Mexico.
