The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Recommended - Individuals: transactions

With a century-long legacy of protecting and enforcing IP rights, Kasznar Leonardos is a go-to for patent prosecution, litigation and transactions. Combining regulatory and IP know-how to superb effect, the side performs exceptionally well in the courtroom: star quarterbacks Gabriel Francisco Leonardos and Claudio Roberto Barbosa neatly side-step potential pitfalls and present cogent, coherent arguments to carry the day. Leonardos’ additional facility for getting IP-rich deals inked feeds into his contentious practice; while Barbosa is “ingenious in coming up with strategies to solve legal and technical puzzles”: “Even in the most trying situations, he never loses his cool and gives logical and balanced advice.” Further transactional strength comes from former president of the Brazilian Association of Intellectual Property (ABPI) and senior stateswoman Elisabeth Kasznar Fekete, who marries IP knowledge with a refined commercial sensibility. She speaks seven languages and understands the numbers game better than anyone, thanks to a career spent matchmaking between high-flying patent owners. The prosecution wing is in the safe hands of João Luis D’Orey Facco Vianna, Gustavo José Ferreira Barbosa, Tatiana Almeida Silveira and Priscila Kashiwabara. Medical doctor Vianna is a fan favourite in the life science and biotechnology sectors: “His academic background, and his ability to listen and learn who the client is and what it wants, make his input worth its weight in gold.” Barbosa heads the electronics, computer sciences, aeronautics and industrial designs division, and is a precision prosecutor with an enviable track record of reversing rejections before INPI. Silveira’s specialises is chemistry; her combination of technical nous and regulatory know-how is a boon for foreign clients entering the Brazilian market. Making her first appearance in the IAM Patent 1000, Kashiwabara is a “fantastic strategist and provides exactly the sort of advice in-house counsels are looking for: quick, direct to the point and practicable”.
