A Watchdog Without Rules: The Missing Standard in Mexico's New IP Office Committee Guidelines

How long Mexico's IP office has to decide and what changed in 2026

Before the April 2026 reform, the statute did not establish a binding maximum period for IMPI to grant or refuse a right. To be fair, an unopposed trademark application could be decided in approximately six months; nevertheless, years could pass without an answer from IMPI. For patents, the situation was more complex and delays could also last years.

The Decree published on April 3, 2026, effective April 4, introduced statutory maximum periods for final decisions for the first time. Article 111 Bis provides that the period for a final decision granting or refusing patents, utility models, and industrial designs may not exceed one year from the start of substantive examination. For distinctive signs—trademarks, advertising slogans, and trade names—the maximum is five months under Article 229 Bis, provided there are no office actions or third-party oppositions.

The question many applicants ask—"How long does a Mexican trademark application take?"—now has a statutory answer.

Five months for trademarks; one year for patents from the start of substantive examination.

The next question—"What can I do if the office misses that deadline?"—is precisely what Title Five Bis is intended to answer.

Before the reform, the only real path against administrative silence was judicial: proceedings based on violation of the constitutional right to petition. That path remains available and, I anticipate, will continue to be preferred by practitioners. There is now, in addition, an administrative route whose usefulness must be tested against the risk that it is merely another bureaucratic step.

The mandatory decision procedure

The mechanism appears in Articles 327 Bis, 327 Ter, and 327 Quater of the LFPPI. It operates only at the request of an interested party—never on the office's own initiative—and applies when IMPI exceeds the maximum periods without a final decision. After receiving a request, the Committee has three days to require the official responsible for the application to submit a report containing the formal examination and, where applicable, the substantive examination. The report must be filed within ten business days, and the Committee then has three days to rule on admissibility. If the request is well founded, it may require a final decision; a failure to comply may lead, where appropriate, to administrative liability proceedings.

One easily overlooked point has enormous value for applicants with old files. Under the Decree's transitional rules, the procedure also reaches applications that were pending before the reform once the Committee was constituted. It is not limited to applications filed under the new law; an applicant who has waited two or three years may, in principle, invoke it.

The missing standard in the Guidelines

This is where the instrument published on June 8 encounters its greatest problem. Article 327 Ter requires at least three representatives appointed by IMPI's Governing Board and—this is decisive—imposes no technical or scientific qualification on them. It does not require patent examiners, engineers, chemists, or experts in the subject matter of the file they will assess. Far from filling that statutory gap, the Guidelines reaffirm it by assigning the Committee to Governing Board representatives holding director-level, honorary positions. More importantly, they establish no substantive decision standard. They do not define "unjustified delay," distinguish negligence from legitimate complexity, state what makes an official's report sufficient, or explain how it must be assessed.

The Guidelines allow the heads of IMPI's Patent and Trademark Divisions to participate as invited officials with speaking rights. Their involvement may contribute specialized knowledge, but it does not fully resolve the problem: invited officials do not sit on the Committee as voting members, and the Guidelines do not explain how their technical views must be incorporated into the final determination.

Imagine an ordinary case. An applicant starts the procedure; the Committee requests the report; and the responsible official says the delay results from the file's technical complexity, the division's workload, and the large number of claims requiring a detailed novelty and inventive-step analysis. With what intellectual tool can a member without technical training refute that justification? How can that member determine that forty claims in a pharmaceutical chemistry file should have been decided within twelve months without the knowledge needed to assess the work involved? The uncomfortable answer is that the member cannot. If the explanation cannot be refuted, any delay, however chronic, can be presented as justified simply by invoking difficulty.

The body created to address delay ends up lacking the capacity to identify it.

Five hundred examiners: the government identifies the underlying problem

When Vidal Llerenas Morales was introduced as IMPI's new head on June 1, 2026, Economy Secretary Marcelo Ebrard announced, according to IMPI's official release, that the office would have 500 professionals in science, technology, engineering, and law serving as patent and trademark examiners.

That fact is revealing because it reinforces the diagnosis that a substantial part of the backlog results from available technical capacity. If the government's announced solution is to expand the examiner workforce significantly, it is reasonable to infer that insufficient specialized personnel form part of the institutional bottleneck. If that is the diagnosis, it is even harder to explain why the assessment of delay justifications is entrusted to a committee without a technical profile. This institutional-capacity problem should also be read together with IMPI's recent operational acceleration, because faster prosecution will be sustainable only if the technical quality of decisions is preserved.

Transparency and accountability: the Article 17 repository

A body charged with monitoring deadlines should, as a matter of basic coherence, itself be subject to oversight. Who can ensure that the Committee does not systematically accept the explanations it receives if no one can audit its decisions? Article 17 of the Guidelines calls for an electronic repository of the Committee's activities. That is the design's decisive test. Will the repository be public or merely internal? What will it contain—requests, reports, decisions, outcome statistics? How will it coexist with confidential information?

The final question is, in my view, the most important. Article 24 of the LFPPI imposes absolute confidentiality over unpublished pending files and provides that unpublished patent, utility model, and industrial design applications may be inspected only by the applicant or authorized persons. Yet the mandatory decision report must include formal and substantive examination of files that may still be unpublished. The repository is trapped between transparency, which justifies its existence, and confidentiality, which protects the inventor. Closing it to the public would create an unauditable oversight body; opening it indiscriminately could compromise unpublished applications. A possible solution—publishing decisions and statistics separated from confidential technical content—is another matter the Guidelines do not regulate, and the mechanism's credibility depends on that detail.

The deadline the Committee's own creation missed

One detail cannot be omitted because of its symbolic value. The Decree's transitional provisions ordered the Governing Board to constitute the Committee and issue the Guidelines within thirty days after the reform took effect. The effective date was April 4, 2026. The Committee was constituted on May 26 and the Guidelines were published on June 8. Was the deadline exceeded?

I calculated it under both possible readings and using both business and calendar days. The Committee's constitution and publication of the Guidelines exceeded the established period.

The mechanism designed specifically to monitor whether the authority complies with deadlines therefore began its existence by missing the deadline established by the reform itself—an unpromising sign for its effectiveness.
