The IMPI API for trademark search

The Instituto Mexicano de la Propiedad Industrial (IMPI) is the Mexican federal agency responsible for examining and registering trademarks, patents, industrial designs, utility models, and geographical indications in Mexico. Operating as a decentralized agency under the Secretaría de Economía (Ministry of Economy) and headquartered in Mexico City, IMPI administers the country's industrial property system under the Ley Federal de Protección a la Propiedad Industrial — the Federal Law for Protection of Industrial Property that entered into force on November 5, 2020 as part of Mexico's USMCA (T-MEC) implementation, replacing the prior Ley de la Propiedad Industrial.

Mexico is the largest trademark filing jurisdiction in Spanish-speaking Latin America by volume, with IMPI receiving roughly 150,000–200,000 trademark applications per year — historically around 140,000 in 2019–2020 and trending higher through the USMCA era. The Madrid Protocol entered into force for Mexico on February 19, 2013, making IMPI the designated office for international registrations covering MX; Madrid designations now sit alongside continued strong direct-national volume from both domestic Mexican applicants (typically S.A. de C.V. or S.A.P.I. de C.V. entities) and foreign holders filing through local representatives. The 2020 statute also introduced non-traditional marks (sound, scent, trade dress, holograms) and a "secondary meaning" doctrine, expanding what's registrable beyond the historical text-and-logo register. An opposition system was introduced by decree in 2016 — third parties have one month from Gaceta publication to file opposition, with no extension permitted, and opposition does not suspend the examination timeline.

IMPI exposes the register through several free public channels but no general-purpose REST API. MARCAnet (marcia.impi.gob.mx) is the longstanding External Consultation Service for Trademark Information — a web search UI covering text, owner, application number, and registration number, plus a dedicated phonetic search. MARCia is the newer AI-augmented tool layered on top of MARCAnet, adding Boolean text filtering and image search where you upload a logo and the system returns visually similar marks. SIGA (siga.impi.gob.mx) provides query forms for locating records from the Gaceta de la Propiedad Industrial, the official weekly electronic bulletin (biweekly in print) that publishes every prosecution event — new applications, oppositions, deferrals, registrations, renewals, and lapses. Signa is building its IMPI connector against MARCAnet, MARCia, and the weekly Gaceta supplements for Q4 2026; on launch it will normalize the Spanish-language register, the Federal Law's event vocabulary, and Madrid designations of Mexico into the same unified schema used for USPTO, EUIPO, INPI Brazil, and every other office.
