How to Register a Trade Mark in Brazil with the Brazilian INPI: A Practical Guide for Foreign Businesses

Registering a trade mark in Brazil follows the familiar arc: you file, an examiner reviews, third parties get a window to oppose, and a certificate issues on payment of the relevant fees. The local context is what matters. Brazil's national office is the Brazilian INPI (Instituto Nacional da Propriedade Industrial), which is a separate body from the French INPI of the same initials; everything in this guide concerns the Brazilian office. Filing is in Portuguese, foreign applicants generally act through a Brazil-based representative, and the system changed shape when Brazil joined the Madrid Protocol (in force October 2019). This guide walks through the process under Brazilian law and explains where the real risks sit. It is general information, not legal advice.

Who can apply

Any natural person or legal entity may apply to register a trade mark in Brazil, whether Brazilian or foreign. There is no need for a Brazilian company or a local establishment to file, although applicants are generally expected to have a lawful activity that relates to the goods or services claimed.

The practical constraint for foreign applicants is representation. An applicant who is not domiciled in Brazil generally must appoint a representative based in Brazil, who is empowered to receive service and to act before the Brazilian INPI, including in administrative proceedings. In most cases foreign businesses work through a local trade mark attorney or agent rather than filing from abroad. Treat this as a structural feature of the system, factor it into your timeline from the outset, and confirm the current requirement for your circumstances with a qualified local professional.

Searching and clearance before you file

Brazil does not force you to search before filing, but filing blind is a false economy. The Brazilian INPI examines applications against earlier marks, and a conflicting prior registration or application is a common ground for refusal. A pre-filing clearance search lets you weigh that risk and adjust the mark or the specification before you commit.

The Brazilian INPI provides official online search facilities, and a professional search through a local representative adds interpretation that a raw database lookup cannot. Treat any search as a snapshot rather than a guarantee: recently filed applications may not yet be fully visible, and examiner judgement varies. Where a result is ambiguous, that is exactly the kind of nuance to put in front of a qualified local firm. For the broader picture of how Brazilian trade marks fit together, see the Brazil trade marks pillar.

Classification and multi-class filing

Brazil uses the international Nice Classification of goods and services, the same framework used in most jurisdictions. The class structure is set internationally and is revised periodically, so confirm the current edition and the classes that fit your goods or services with the Brazilian INPI or your representative. Drafting the specification deliberately matters: prefer terms the Brazilian INPI recognises where possible, because non-standard descriptions can attract office actions and slow examination.

One change is worth flagging for anyone working from older guidance. Historically Brazil required a separate application per class. Around the time Brazil acceded to the Madrid Protocol (in force October 2019), the system moved towards multi-class applications and co-ownership of marks, with the practical mechanics phased in through the office's electronic filing system rather than switched on at a single date. The detail of how multi-class filings are administered and charged continues to be refined, so confirm the current position and the fee structure with the Brazilian INPI or your local representative rather than relying on a fixed account here.

Filing in Portuguese

Portuguese is the language of the Brazilian INPI. Applications, responses to office actions, and submissions in opposition or other proceedings are made in Portuguese, and supporting documents in another language may need a translation. This is one of the main reasons foreign applicants work through a Brazil-based representative who can both file correctly and manage correspondence as it arrives. Build the translation and local-handling step into your plan rather than treating it as an afterthought.

The application and examination process

An application to the Brazilian INPI includes the applicant's details, a clear representation of the mark, and the list of goods or services classified under Nice. If you claim priority from an earlier foreign application under the Paris Convention, you must do so within the priority period, which for trade marks is generally six months from the first filing, and provide the supporting documents within the time the rules allow. Both the priority period and the documentary deadlines are time-sensitive, so confirm the current figures with the Brazilian INPI or your representative rather than relying on the general position stated here.

After filing, the process broadly runs through formal checks, publication, an opposition window, substantive examination on absolute and relative grounds (such as distinctiveness and conflict with earlier marks, which the office assesses of its own motion against earlier marks), and then grant on payment of the relevant fees. Official fees apply at filing and at grant; confirm the current amounts with the Brazilian INPI or local counsel rather than relying on any figure. Where the office raises an objection, you are given a period to respond, and an adverse decision can generally be appealed within the period set by the rules. These periods are time-sensitive and version-specific, so confirm the exact current deadline with the Brazilian INPI or your representative as soon as an action issues.

Publication and opposition

Brazil publishes applications in the official IP gazette, and there is a defined period during which third parties may file an opposition before substantive examination concludes. Opposition is the main pre-grant route for an earlier rights holder, or other interested party, to challenge a mark. If an opposition is filed, the applicant is given an opportunity to respond before the examiner decides.

If no opposition is filed, or an opposition does not succeed, the application proceeds to grant once the relevant grant fees are paid. Registered marks can later be challenged through administrative nullity or, on non-use grounds, through forfeiture proceedings, but those are post-grant tools rather than part of the initial opposition window. Because the deadlines and grounds are specific and time-limited, monitoring the gazette and acting quickly matters, and a local firm can run watch services and file within the deadlines.

Registration, fees and renewal

A trade mark is granted once examination is passed and the grant fees are paid; the registration is evidenced by a certificate. A Brazilian registration runs for a fixed term and is renewable, typically for successive equal periods, provided each renewal is filed and paid within the applicable window. The precise term, the renewal window, whether renewals can continue indefinitely, any post-expiry grace period, and the associated charges are version-specific, so rather than relying on any figure here, confirm the current term and renewal rules with the Brazilian INPI or through your representative. Diarise renewals well ahead: missing the window risks loss of the registration.

Historical timelines

Brazil has a reputation for long pendency in both trade marks and patents, and the backlog was a genuine planning factor for many years. The Brazilian INPI has invested in reducing it, and processing times have generally improved, though they still vary with the workload, whether an opposition is filed, and whether the office raises objections. Treat any single duration as a planning assumption rather than a commitment, file early, and confirm current processing expectations on the Brazilian INPI's official channels or through your representative.

As background on the wider system, a few features show why confirming the current position matters, though none of them changes the trade mark route. Pharmaceutical patent applications in Brazil have required prior consent (anuencia previa, prior approval) from ANVISA, the health regulator, in addition to the Brazilian INPI; ANVISA's role here applies to pharmaceutical product and process applications and has been narrowed and clarified over time, so confirm the current scope with counsel rather than treating ANVISA as a blanket second examiner. Brazil also recognises a utility model (modelo de utilidade, a protection for incremental technical improvements) and acceded to the Hague designs system (the Geneva Act reported in force in August 2023, a point to verify before relying on it). In 2021 Brazil's Supreme Federal Court (the STF) struck down the rule that had guaranteed a minimum term to patents that had taken years to grant, an example of how Brazilian IP rules can shift.

Filing directly versus the Madrid Protocol route

Foreign businesses generally reach Brazil by one of two routes: a direct national filing through a Brazil-based representative, or an international registration designating Brazil through the Madrid Protocol, administered by WIPO. Brazil has been a Madrid member since the system came into force for it in October 2019, so designating Brazil is now a practical way to add Brazilian protection to a wider international programme.

Each route has trade-offs. A direct national filing lets you tailor the specification to Brazilian practice from the start and respond to office actions through a representative already on the file. A Madrid designation can be more economical when you are filing in several countries at once and lets you manage a portfolio centrally, but the specification is inherited from your base application, and any objection or opposition raised in Brazil still has to be handled locally. For the Brazil-specific mechanics of the Madrid route, see our guide to the Madrid Protocol in Brazil, and for the wider system see our overview of the Madrid Protocol.

IPEnvoy is not a law firm and does not provide legal advice; this is general information. Official requirements, fees, and processing times are set by the Brazilian INPI and change over time, so confirm the current position on the Brazilian INPI's official website and with a qualified local IP professional before you file.
