"Guerra IP has a great team of trademark practitioners who provide stellar quality services and are very easy to work with. Their service for the entire Latin American region, handled in association with their growing network of local best professionals, is particularly appreciated. This network is an advantage for their clients that may work with just one reliable service hub, which makes the works flow easily and more efficiently.” The team is led by Cristina Guerra in Porto Alegre. “Cristina is knowledgeable, responsive and practical. Along with deep know-how in the Brazilian and larger Latin American markets, Cristina is also well versed on China IP matters. From prosecution work to litigation, she is very reliable, responsive and easy to work with – it is difficult to imagine finding a better cooperation partner in the region. Even though there are larger IP firms in Brazil I would always choose Guerra IP, since working with them is much more personal, streamlined and of consistent quality across the entire firm. I highly recommend Cristina and her team and look forward to many more years of cooperation.”

"Southern Brazil's top IP outfit, Guerra IP also has a major presence in Rio de Janeiro and is a respected name across Brazil and internationally, too. Patrons benefit from easy partner access and a trademark service that is tailored and rigorous, but also price sensitive. Its appreciation of the business criticality of brands makes it well suited to transactional IP tasks and inspires its problem-solving approach to litigation, where costly proceedings are often avoided without compromising on results. Helping to instil this commercial approach, Cristina Guerra presides over the trademark department. One long-term client reports: “We have worked with her for over a decade and never been less than extremely satisfied with her performance and responsiveness.” Another adds: “Cristina has represented us in Brazil for 20-plus years; she takes prompt action and implements creative solutions.” She designs international strategic blueprints for Brazilian companies and manages the Latin American portfolios of large multinationals with a deft touch. When she links up with polished litigator and deal maker Ricardo Pinho, great things happen; the pair are currently overseeing wide-ranging trademark matters for a leading global cannabis company. Pinho is “one of the best IP attorneys in Brazil in terms of substantive knowledge and strategic expertise”.
