Intellectual Property

Trademarks represent one of the biggest assets of a company. In Brazil, ownership is acquired through a registration at the Brazilian Patent and Trademark Office (BPTO). In each country, however, the way of acquiring this right has peculiarities that require advice that is qualified and attentive to the challenges presented by a globalised market.
From cutting-edge technology and the pharmaceutical market to highly-segmented niches such as high luxury or biotechnology, we work with business guidance, seeking to understand our clients’ business in order to offer creative, objective and appropriate solutions for their needs.
We also have an extensive network of associates in more than 150 countries in the main global markets, which allows us to offer effective international assistance at optimised costs.
