1. About Patente Law in Brazil
The Brazilian patent system is governed mainly by the Industrial Property Law, known as Lei de Propriedade Industrial. This framework covers patents for inventions and utility models, as well as related rights and procedures handled by the national patent office INPI. In Brazil, patents generally provide exclusive rights to the inventor for a set term, subject to examination and payment of maintenance fees.
Inventions (patentes) and utility models (modelos de utilidade) have different term lengths, with a typical term of 20 years for inventions and 15 years for utility models, measured from the filing date. This duration is designed to balance innovation incentives with public access. The patenting process includes filing, substantive examination, possible office actions, and, when granted, enforcement against infringers.
Brazil follows a first to file approach for patent applications and relies on INPI to evaluate novelty, inventive step, and industrial applicability. While Brazil allows domestic and international filings, foreign applicants must work through the national route or a PCT process that enters the Brazilian national phase via INPI. For up-to-date procedures, fees, and forms, consult INPI's official resources.

4. Frequently Asked Questions
What is a patent in Brazil and what protections does it provide?

How long does the Brazilian patent examination usually take?
