Founded in 2013 PATENTREE provides specialised IP services. The firm’s partners and associates have extensive experience in IP prosecution in all fields of intellectual property.

PATENTREE’s professionals are highly qualified and have in-depth experience in drafting, prosecuting and enforcing patents in Europe, the United States and other jurisdictions. Our firm is characterised by our unfailing commitment to excellence and strong IP strategies. Whether the work entrusted to us is patent drafting, patent searches, prosecution, oppositions, freedom-to-operate reports or patent validation, it is quality checked to ensure that it meets the highest standards.

We are a ground-breaking firm in Portugal and currently the only patent firm employing several qualified European patent attorneys. We specialise in both electromechanical and chemical technology fields.

For the fifth consecutive year, PATENTREE has been recognised by the IAM Patent 1000 as a leading patent firm in Portugal employing leading patent individuals. In 2019 a Financial Times and Statista special report on leading European patent law firms listed PATENTREE among Europe’s top 150, awarded with Gold and Silver status. We are known for our team of responsive advisers, our ability to communicate effectively with scientists and investors, as well as for our success rate in prosecution, opposition, intervention and appeal cases. We strive to do our best to help our client protect their IP rights. We work closely with clients in order to fully understand their technology and to provide solutions specifically tailored to their needs.

We are a dynamic team of molecular biologists, bioengineers, mechanical and electrotechnical engineers. Among our team of professionals, some are former scientists, patent and trademark examiners, as well as IP consultants. They are dedicated to raising IP awareness in Portugal and to continuously be involved in providing patent law training courses in Portugal and abroad. We have been involved in providing tutoring for the University of Strasbourg Centre for International Intellectual Property Studies, as well as for the Institute of Professional Representatives before the EPO.

PATENTREE’s professionals have extensive experience before the patent and arbitration courts – in particular, as experts and technical assistants who have received the European patent litigation certification. Our professionals also have extensive experience and in-depth skills in patent searching. We use multiple world-class databases and tools when preparing reports in relation to patentability, freedom to operate and infringement.
