Testimonials

  • ‘I met the Gusmão & Labrunie team about fifteen years ago, and during this years I appreciated the valuable professional skills of the team, their proactivity, the very high knowledge of the legal environment, the rigorous approach, being client-oriented without the aim to necessarily provide the answer the client wants to hear from them, offering a realistic picture and studying together with the client the best way. I deem Gusmão & Labrunie as the most reliable and with the highest-profile IP firm in Brazil.’

  • ‘Professionalism, technical knowledge of the role and availability.’
