Reform of Mexico's Federal Law for the Protection of Industrial Property (LFPPI)

On April 3,2026, the Decree reforming the Federal Law for the Protection of Industrial Property (LFPPI) was published, bringing with it several significant changes with which the government seeks to modernize the system for protecting inventions in Mexico and align it with international standards.

This reform allows for the claim of the entitlement of a patent or registration that was improperly granted, as well as the inventor's right to be mentioned in the publication of an application or granted right.

It enables the reinstatement of priority rights outside the period established by the Paris Convention, which must be requested within two months of the expiration date.

It introduces the concept of "provisional applications," similar to that known, for example, from the United States.

It reduces to one year the period for resolving the substantive examination of a patent application, during which only two official actions will be issued, according to a new provision, instead of the four previously established. It establishes a Specialized Technical Committee to which complaints can be submitted if the established time frames for granting industrial property rights are not met.

It also provides for the issuance of supplementary patent protection certificates in cases of unjustified delays in issuing the corresponding marketing authorization.
