PATENT REGISTRATION IN BRAZIL
Patent Registration in Brazil
Brazil is Latin America’s largest economy and one of the region’s most important innovation markets, making patent filing in Brazil strategically important for businesses, startups, and inventors. Patent protection is administered by Brazil’s National Institute of Industrial Property (INPI) and generally moves through prior art search, application drafting and Portuguese submission, formal review, publication, substantive examination, and grant. A granted invention patent is valid for up to 20 years from the filing date, and a utility model patent is valid for up to 15 years from the filing date, subject to payment of required fees.
Patent Filing Process in Brazil: Steps and Timeline
The table below outlines the complete patent filing process in Brazil, from initial search through grant and maintenance.
| Step | Stage | Estimated Timeline |
|---|---|---|
| 1 | Prior Art Search | Approx. 1–3 weeks for a preliminary search; longer for complex technologies. |
| 2 | Application drafting and Portuguese preparation | Approx. 2–4 weeks, depending on invention complexity and claim scope. |
| 3 | Filing with INPI | Usually 1–2 days once documents are ready; for PCT national phase, entry must be made within 30 months of the earliest priority date. |
| 4 | Formal review | Timing varies, usually within the first months after filing depending on INPI workload and completeness of filing. |
| 5 | Publication in the Industrial Property Gazette (RPI) | Confidentiality lasts up to 18 months from the filing date, unless early publication is requested. |
| 6 | Request for substantive examination | Must be filed within 36 months from the filing date. |
| 7 | Substantive examination and office actions | Often takes several years, depending on backlog, technology area, and response speed. |
| 8 | Grant and maintenance | Grant timing varies; annuities continue throughout the life of the application and patent. |
Detailed Explanation of Each Step
Step 1: Patentability Search & Strategy
Before filing, it is advisable to search prior art in INPI and international databases to assess novelty, inventive step, and industrial applicability. This helps determine whether the invention is better filed as an invention patent or utility model. A search usually takes one to three weeks.
Step 2: Application Drafting & Portuguese Translation
The patent application includes a specification, claims, abstract, and drawings if applicable. Portuguese is required for filing, and foreign applicants should ensure the application is properly translated before submission. Drafting usually takes two to four weeks.
Step 3: Filing with INPI
Applicants can file directly in Brazil or enter through the PCT national phase. The PCT national phase deadline is 30 months from the earliest priority date. Foreign applicants should use a Brazilian patent attorney or agent for prosecution before INPI.
Step 4: Formal Review
INPI reviews the filing for completeness, required documents, and payment evidence. If any items are missing, INPI may issue a communication requiring correction within a stated period. The exact timing depends on the filing and INPI workload, so it should not be presented as a fixed 2–6 months period.
Step 5: Publication in the Industrial Property Gazette
After filing, the application is kept confidential for up to 18 months from the filing date, unless early publication is requested. This is the correct rule to state instead of a fixed publication timing that varies by processing stage.
Step 6: Request for Substantive Examination
The applicant must request substantive examination within 36 months from the filing date. For that request, INPI uses code 203 for invention patents and code 204 for utility models. Missing this deadline is a critical risk and may result in the application being shelved.
Step 7: Substantive Examination & Office Action Responses
INPI examines novelty, inventive step, and industrial applicability. The examination phase can take several years, and office actions must be answered within the deadline set by INPI. A general estimate such as “2–5 years” should be presented only as an approximation, not as a guaranteed timeline.
Step 8: Grant, Annuities & Maintenance
If granted, the patent is valid in Brazil for 20 years for an invention patent and 15 years for a utility model, counted from the filing date. Annual fees are due starting from the 24th month after filing, and continued non-payment may lead to lapse.

No. Foreign individuals and companies must appoint a patent attorney or agent registered in Brazil to file, prosecute, and receive official INPI communications on their behalf.
Substantive examination must be formally requested within 36 months of the filing date (or international filing date for PCT applications). Missing this deadline shelves the application permanently.
Yes. Brazil is a PCT member state, and national phase entry must occur within 30 months of the earliest priority date, with no general extension available.
