Luiz Leonardos & Advogados

6th Floor, Av Rio Branco 80
Rio de Janeiro

Luiz Leonardos & Advogados mixes expertise and resourcefulness gained in almost 100 years of work devoted to intellectual property in Brazil with the advantages of a newly created framework, one that is more effective and personal in client interaction. Created as a direct result of the split of Momsen Leonardos & Cia into two firms on April 30, 2012, Luiz Leonardos & Advogados has 18 partners and more than 60 experienced professionals dedicated to all areas related to intellectual property.

Legal excellence and solid ethical conduct were the principles that guided Momsen for almost 100 years, and they continue to guide Luiz Leonardos & Advogados as a natural heir to this juridical background. All IT systems, database and controls were inherited, having been developed over decades, and continue to improve.

The experience acquired by the senior partners, who have 50 years of distinguished practice in IP, enabled the formation of a highly specialised team of attorneys, engineers, biologists and industrial property agents, who collectively bring extensive knowlegde across all fields.

Luiz Leonardos & Advogados provides all the assistance necessary to obtaining, maintaining and protecting intellectual property rights, not only in the administrative sphere, but also before the Brazilian Courts, with the traditional level of service known in intellectual property in Brazil.

Luiz Leonardos & Advogados emphasises transparency in its relationship with clients, third parties, service providers, and with all its peers in general, which is believed to be its strongest asset. The firm has also developed a state-of-the-art system that is designed to meet the constantly changing needs of IP control. Luiz Leonardos & Advogados’ goal is to assist clients through providing efficiency and value, and fulfil the demands of the current market.
