The Mexican Institute of Intellectual Property (IMPI) has adopted administrative simplification measures, through amendments to the Law and examination agreements, aimed at expediting the prosecution of patent applications.
New examination scheme (effective March 12, 2026)
- Applies, in principle, to applications filed on or after March 12, 2026;
- However, cases filed prior to this date that have already entered substantive examination are also being dealt with under this scheme;
- Limits substantive examination of patents and utility models to a maximum of two office actions.
LFPPI Reform (effective April 4, 2026)
- Establishes that substantive examination must begin as soon as possible following publication;
- Results in accelerated initiation of examination for applications filed in 2026;
- Introduces the possibility of telematic meetings during substantive examination, either at the applicant’s request or at IMPI’s initiative through official action;
- Such meetings are consultative only and have no binding effect on the procedure.
These measures reflect IMPI’s policy objective of streamlining administrative processes. However, the limitation to two office actions and the accelerated examination timelines raise concerns regarding applicants’ procedural rights; particularly, the limitation to the right of audience and to the opportunity to adequately address substantive objections.

Advisory to applicants
Accordingly, applicants are strongly encouraged to submit any amendments or adjustments to the claims at the earliest possible stage, preferably once formal requirements have been satisfied, so that the subject matter of greatest interest is under examination from the first office action.
