Sonia Carlos Antonio is an intellectual property practitioner with more than four decades of experience in the field, having practiced since 1985. She is the managing partner of CNV IP Law Firm, where she advises Brazilian and international clients on a broad range of intellectual property matters. Her practice encompasses trademark and patent prosecution, portfolio management, enforcement, and related proceedings before the Brazilian National Institute of Industrial Property (INPI). Throughout her career, she has developed extensive experience advising foreign companies and law firms on Brazilian IP strategy and practice, with particular emphasis on the procedural and substantive aspects of intellectual property protection in Brazil.
Brazil is one of the world’s largest economies and one of the most important markets for companies seeking expansion in Latin America. However, many foreign applicants quickly discover that success before the Brazilian Patent and Trademark Office (the Instituto Nacional da Propriedade Industrial – INPI) requires more than simply filing an application. The Brazilian system combines procedural formalities, relatively long examination timelines, unique legal requirements, and several acceleration opportunities that are often overlooked by foreign applicants. Understanding these practical aspects can help businesses avoid unnecessary delays, reduce costs, and build stronger intellectual property portfolios.
