IMPI Issues New Regulations: Optimizing the Administration of Substantive Examination for Patents

Release Time：2026-03-25 11:21Author：Views：16

The Mexican Institute of Industrial Property (IMPI) published an announcement in the Official Gazette on March 11, revising the examination rules for utility models and patents. The revision is intended to improve the supervision and service quality of industrial property by simplifying administrative procedures and strengthening communication mechanisms.

The revision introduces a core adjustment to Article 11 of the original agreement. First, in the substantive examination of applications for the registration of patents or utility models, IMPI may issue a maximum of two office actions to the applicant to advance the examination process and improve the application documents.

In the meantime, the revision adds a remote meeting communication mechanism. Applicants may take the initiative to apply for a remote video meeting with examiners during the substantive examination period; IMPI may also proactively propose a meeting after issuing the first office action to analyze patentability-related issues based on the prior art, establishing a direct and efficient technical communication channel for both parties.

This agreement shall take effect on March 12, 2026. Applications filed prior to this date shall still be examined in accordance with rules in force at the time of filing, so as to avoid any disruption to the ongoing examination application.

This revision will further harmonize the industrial property supervision system, align with the optimization of supervision policies, and facilitate the comprehensive implementation and improvement of administrative simplification measures.
