IMPI (Mexico's IP office) will examine patents for the world from January 2027 while carrying 133 thousand files of its own and more than tripling its examiner staff
Translated from the Spanish original.
On July 13, 2026, the Assembly of the Patent Cooperation Treaty Union approved by consensus the designation of the Instituto Mexicano de la Propiedad Industrial (IMPI, Mexico's industrial property office) as an International Searching Authority and International Preliminary Examining Authority. It will be the fourth office providing that service in Spanish, along with Spain, Chile and Brazil, and it is expected to begin operations in January 2027. As of June 15, 2026, the institute reported 133,211 files pending analysis: 56,211 patent files—of which 44,239 were in the technical examination phase, with the largest accumulation in biotechnology and chemistry—and some 77,000 distinctive sign files. The patent backlog has been falling: the management report of May 28, 2026 reports a drop from 55,377 to 43,740 files after a 74% increase in staff. That staff went from 112 examiners at the start of the administration to some 192, and with the call for 500 more, closed on June 27, 2026 with a monthly pay of 27,000 pesos, IMPI expects to exceed 700.
Strategic interpretation
SYSTEMIC (verified + inferred): the easy reading—an overwhelmed office takes on international work—does not hold up, which makes the signal better. IMPI (Mexico's IP office) is in fact building capacity: 74% more examiners, a falling patent backlog, and a designation WIPO does not grant without technical accreditation. The real tension is simultaneity. All that capacity is new: staff went from 112 to more than 700 in about two years, so in January 2027 international examination will fall on examiners with months of seniority, trained while 133,211 files are being cleared. The State wins, displaying accreditation; the foreign applicant wins, gaining a brand-new authority in Spanish; the domestic applicant, whose file has no penalty-backed deadline while the international one does, absorbs the risk. CONSEQUENCE (inferred): it falls first on the Mexican company with a pending patent in biotechnology or chemistry, since the accumulation is there. From this follows something hardly discussed: under scarcity, whatever has a mandatory calendar gets served first. Over 3-10 years, if staffing does not stabilize, Mexico would have built an international authority on a precarious contractual base, and the fast track to protect a Mexican invention would run through the international system, not the national one. WORLDVIEW: that technical capacity is accredited once and then exists. The designation certifies that IMPI can examine to an international standard; it does not say how many files it can get through, nor how long those who learned to do it will stay. WHAT TO WATCH: whether the 500 examiners end up in budgeted positions or on renewable fee-based contracts (the data point is not public, and it decides the signal); whether the 133,211 inventory falls or rises in IMPI's 2027 annual report; and whether the time to first examination in biotechnology and chemistry diverges from the response time as an ISA. That gap is the exact measure of the tension.
Imagen Radio, June 15, 2026, with the inventory breakdown (133,211 = 56,211 patents + ~77,000 distinctive signs) and the staffing figures. The ISA/IPEA designation of July 13, 2026 was checked against the legal note by Basham, Ringe y Correa. The patent backlog going from 55,377 to 43,740 and the 74% rise in examiners come from Santiago Nieto's management report of May 28, 2026. The sum 56,211 + 77,000 = 133,211 was recalculated by hand. The sources disagree on the nature of the hiring: one speaks of 500 plazas (budgeted positions) and another of initial honorarios (fee-based contracts) with an intention of permanence; it is not resolved here.
