“PATENTREE is a great choice for patent prosecution in Portugal. Its attorneys have extensive technical backgrounds and have the necessary knowledge to understand inventions quickly, which helps clients address potential objections. It is an outstanding IP firm.” Priding itself in offering cost-effective and comprehensive services, PATENTREE has a strong European patent practice, with numerous highly accomplished attorneys who are well versed in prosecuting at the EPO. “Under Luís Ferreira’s leadership, the team works like a well-oiled machine. His prowess in electrical engineering shines through with his deep understanding of technical issues and clear advice. He really wants to understand the invention and bring new angles that positively impact the overall quality of the patent text. A true ally throughout the patent process, Luís is a uniquely intelligent attorney.” A specialist in chemistry and pharmaceutical patent cases, Anabela Carvalho can resolve even the most difficult substantive patent issues. “Anabela has in-depth knowledge of the IP registration processes and registration strategy, as well as extensive knowledge in appeal procedures. She works excellently with clients and provides helpful guidance to navigate complex patent prosecution cases.” Working alongside her is technology expert Ricardo Abrantes, who is respected by patrons for his business-oriented and strategic legal advice in materials and mechanical patent cases.
