With an unparalleled understanding of the inner workings of INPI, Montaury Pimenta, Machado & Viera de Mello is one of the most prolific prosecution outfits in Brazil. “Amazingly responsive and flexible with fees, it gives the impression of exclusivity to its clients.” Leading by example is trademark chief Eduardo Magalhães Machado, who has a flair for the fine print of brand management and licensing agreements. He has built up a first-rate team, including Clarissa Jaegger, a trusted portfolio adviser on many key accounts. With a professional command of five languages, she is well equipped to provide cross-border counsel – as are Joana de Mattos Siqueira and Luiz Edgard Montaury Pimenta. The firm’s foreign department head and president of ASIPI’s Trademark Committee, Mattos Siqueira is a truly well-connected practitioner whose constructive relationships with governmental and judicial authorities deliver benefits for multinationals such as Uber. The same may be said of Montaury Pimenta, the current president of the Brazilian Intellectual Property Association. He is a vital cog in the firm’s litigation practice alongside Ana Paula Affonso Brito, who proposes “business-minded, creative solutions in a fast manner”. Finally, Marianna Furtado de Mendonça makes her first entry in the WTR 1000 for 2021, having put in polished contentious performances for the likes of Hard Rock Café. “She really cares for her clients, putting in extra hours without ramping up ridiculous billing rates. Her legal, practical and commercial acumen results in balanced and successful strategies.”
