Brazil Utility Model (Modelo de Utilidade): A Practical Alternative to a Patent

Brazil offers two routes for protecting a technical invention: the full invention patent and the utility model, known in Portuguese as the modelo de utilidade (literally a "model of utility"). The utility model is not simply a weaker patent. It is a distinct instrument with its own subject matter and its own bargain, aimed at incremental, practical improvements to the shape or arrangement of an object rather than at complex or pioneering inventions. For a company shipping mechanical products into Brazil, or refining a tool, fitting or device in ways that are genuinely useful but unlikely to clear the higher bar of an invention patent, it can be a sensible part of the protection mix.

This page explains what a Brazilian utility model covers, how the Brazilian INPI examines it, the shorter term it carries, the strategic trade-offs against a full patent, and how it compares with utility models in other countries. One point to settle at the outset: Brazil's national office is the Instituto Nacional da Propriedade Industrial, the Brazilian INPI, which is a different body from the French institute of the same initials. Everything below concerns the Brazilian office. Portuguese is the filing language, and foreign applicants are generally required to act through a local representative in Brazil.

What a Brazilian utility model protects

A Brazilian utility model protects an object of practical use, or a part of one, that presents a new shape or arrangement and, through that configuration, delivers a functional improvement in its use or manufacture. Three threads run through that description and each matters. First, the subject is a tangible object: a tool, a fitting, a mechanical part, a piece of equipment, or a defined part of one. Second, the protected contribution is in the shape or arrangement, the physical configuration, not in an abstract idea. Third, that new configuration must produce a real functional gain, an improvement in how the object works, is used, or is made, rather than a purely aesthetic change. Decoration and ornamentation are the territory of industrial design protection, not the utility model.

The right also requires what Brazilian law frames as an inventive act, the ato inventivo, a threshold that is generally understood to sit below the inventive step (atividade inventiva) demanded of a full invention patent but above mere triviality. The configuration must not be an obvious or commonplace variation to a person working in the field, yet it does not need to represent the leap that a patent requires. Treat the precise statutory wording and the way the inventive act is assessed as points to confirm with the Brazilian INPI's guidance or with local counsel, because the exact reading is jurisdiction-specific and is applied case by case.

A practical consequence of the subject-matter limits is that processes, methods, chemical compositions and substances generally fall outside the utility model. If your contribution is a manufacturing method, a formulation or a process improvement rather than a new physical configuration of an object, the utility model is usually the wrong instrument and the invention patent route is the one to consider. For the broader picture of both rights, see our overview of patents in Brazil.

How the Brazilian INPI examines it

Unlike the utility-model systems in some countries, which register the right with little or no substantive scrutiny, the Brazilian utility model is subject to examination by the Brazilian INPI. The application passes through filing and publication and then, on a request made within a set statutory window, a substantive examination in which the office assesses the application against the requirements for a utility model, including novelty, the inventive act and industrial application, as well as the formal and subject-matter conditions. The length of that window is a fixed statutory figure that changes over time, so confirm the current period for requesting examination with the Brazilian INPI rather than relying on a remembered number. In other words, the validity questions are tested by the office before grant rather than deferred to a later dispute.

That examination is a meaningful difference from a lightly registered right. It means a granted Brazilian utility model has been scrutinised on its substantive merits, which tends to make it a more solid right to hold and to enforce, though no grant is ever immune from a later validity challenge. It also means the timeline to grant includes an examination queue. Brazil has historically had long pendency for patents and trade marks, with reforms and measures aimed at reducing the backlog over recent years; treat any specific waiting time as variable and confirm the current position with the Brazilian INPI rather than relying on a fixed figure. The procedural steps, including how to request examination and the deadlines that attach to each stage, are set out at a practical level in our guide to how to file a patent in Brazil, which covers the utility model route alongside the invention patent and expresses each statutory window as a range plus an official-source pointer rather than a hard figure.

Official fees apply at the various stages of filing, examination and maintenance; confirm the current amount with the Brazilian INPI or local counsel rather than working from any quoted figure, as fees change and vary by route. Because filings in Brazil proceed in Portuguese and foreign applicants act through a local representative, local attorney time is a genuine and usually unavoidable cost driver to factor into any budget.

The shorter term and the strategic trade-offs

The headline trade-off is term. A Brazilian utility model carries a shorter protection period than a full invention patent. As a general guide, a utility model in Brazil runs in the region of fifteen years measured from the filing date, against roughly twenty years for an invention patent, so it is meaningfully shorter; confirm the exact term and the way it is measured with the Brazilian INPI or local counsel, since the precise figures and rules change and are applied case by case. Brazil's term framework has itself been in flux at the margins: in 2021 the Brazilian Supreme Court, the Supremo Tribunal Federal, struck down the provision that had guaranteed a minimum term running from the grant date. That ruling removed the minimum-from-grant floor; the ordinary terms measured from the filing date are the stable point, and the firm general message is simply that a utility model is shorter than an invention patent, which is what should drive the strategic decision.

A shorter term suits an invention with a shorter useful commercial life, which is often the case for an incremental mechanical improvement that a competitor will design around or that the market will move past within a few years. The lower inventive threshold is the other side of the bargain: a configuration that is new and usefully improved, but not inventive enough to support a full patent, can still be protectable as a utility model. That makes the utility model well matched to incremental improvements to the shape or arrangement of an object, and poorly matched to complex inventions, processes, or contributions you expect to commercialise over a long horizon, for which the invention patent is the better home.

There is one Brazil-specific wrinkle worth keeping in view even though it bites mainly on patents rather than utility models. Pharmaceutical patent applications in Brazil are subject to a prior-consent step, the anuencia previa, involving ANVISA (the Agencia Nacional de Vigilancia Sanitaria, Brazil's health surveillance agency) in addition to examination by the Brazilian INPI. The scope and operation of that prior-consent mechanism have shifted over time through joint INPI and ANVISA guidelines, so treat it as a point to confirm with counsel when planning life-sciences filings. It underlines that subject matter drives the route as much as strategy does.

How it compares with utility models elsewhere

Utility models exist in many jurisdictions but the rules differ enough that the Brazilian version should not be assumed to behave like any other. Two contrasts stand out. The first is examination. Some countries, Germany and Japan among the well-known examples, grant a utility model through registration with little or no examination of novelty or inventive step before grant, deferring the validity question to a later challenge or to a separate evaluation step. Brazil instead examines the utility model substantively at the office, which generally yields a more tested right at the cost of a longer path to grant. The second contrast is subject matter: many utility-model systems, including Brazil's, confine the right to the physical shape or structure of an object and exclude processes and methods, but the precise boundaries vary, so a contribution that qualifies in one country may not qualify in another.

Brazil's wider international posture has also shifted in ways that affect how you protect an invention there. Brazil acceded to the Madrid Protocol for trade marks in 2019, and around the same time Brazilian practice adopted multi-class applications and co-ownership, and it has joined the Hague System for industrial designs, in force from 1 August 2023 (confirm the current procedure before relying on it). Neither of those directly governs the utility model, but together they signal a system that is steadily aligning with international filing routes. If you are protecting the same invention across several countries, plan the Brazilian utility model as one node in a wider strategy rather than in isolation, and weigh it against pursuing an invention patent through the international route.

A note on using this

IPEnvoy is not a law firm and does not provide legal advice. The above is general information about the Brazilian utility-model system as administered by the Brazilian INPI, written to help you frame the right questions, not to decide your filing. Subject-matter scope, the inventive-act threshold, examination procedure, fees and the term of a utility model are jurisdiction-specific and change over time, so confirm the current position with the Brazilian INPI's official website and a qualified local IP professional before you file or rely on it.
