What is INPI Brazil?
The Instituto Nacional da Propriedade Industrial (INPI) is the Brazilian federal autarchy responsible for examining and registering trademarks, patents, industrial designs, and geographical indications in Brazil. Operating under the Ministry of Development, Industry, Trade and Services and headquartered in Rio de Janeiro, INPI administers the country's industrial property system under Law Nº 9.279/96 — the Lei da Propriedade Industrial that established Brazil's modern trademark framework.
Brazil's Madrid Protocol membership entered into force on October 2, 2019 (Brazil deposited its instrument of accession with WIPO three months earlier), which fundamentally changed INPI's filing mix. Pre-2019, every foreign trademark holder seeking Brazilian protection had to file directly with INPI through a local representative. Post-accession, holders can designate Brazil through a single WIPO international registration. Madrid designations now account for a growing share of new INPI filings, alongside continued strong direct-national volume — INPI processes roughly 300,000 trademark applications per year, making it one of the largest trademark registries in Latin America and among the busiest in the Global South.
INPI publishes the Revista da Propriedade Industrial (RPI) every Tuesday, a weekly official bulletin with every prosecution event (publications, deferrals, oppositions, registrations, renewals, lapses) of the prior seven days. There is no general-purpose public REST API for the trademark register. INPI offers Busca Web (busca.inpi.gov.br) as a web search UI and a narrow eINPI API for a handful of authenticated services, but neither supports full-featured programmatic search. The INPI Brazil register is on the Signa roadmap and is not on Signa yet. Brazilian marks reach Signa today through WIPO Madrid designations.

Unique features
- Madrid Protocol member since October 2, 2019 — Brazil was the 105th contracting party; international registrations designating BR have grown sharply since accession
- Portuguese-language register — mark text, goods/services descriptions, and status labels are all in Brazilian Portuguese (status codes like Deferido, Indeferido, Arquivado, Sobrestado, Caduco)
- Weekly Revista da Propriedade Industrial (RPI) — every Tuesday INPI publishes all prosecution events of the prior week in a single official bulletin
- Largest LatAm registry by filing volume — roughly 300,000 trademark applications per year, several times the volume of Mexico, Argentina, or Chile
- Sixty-day opposition window from RPI publication — one of the shorter windows globally, with strict in-Portuguese filing requirements
- Local representative required for foreign applicants on direct-national filings — the local agent requirement persists even post-Madrid for non-IR routes
- Industrial Property Law Nº 9.279/96 — the unified statute covering trademarks, patents, designs, and geographical indications under a single examination framework
- No general-purpose public API — Busca Web is a web UI and the eINPI API only covers a narrow set of authenticated services, so bulk access means scraping the web tool or parsing the weekly RPI
