PATENTREE was founded in 2013 with the mission of providing specialized Intellectual Property (IP) services, with a strong focus on patents. Our partners and associates bring over 20 years of professional experience across all areas of IP, ensuring clients benefit from both technical depth and strategic insight.

We are recognized for our excellence in drafting, prosecuting, and enforcing patents in Europe, the United States, and other jurisdictions worldwide. Whether entrusted with patent drafting, prior art searches, oppositions, freedom-to-operate analyses, or validations, our work is always subject to rigorous quality checks to guarantee the highest professional standards.

PATENTREE stands out in Portugal as a pioneering firm, currently the practice with the largest team of qualified European Patent Attorneys. We specialize in electromechanical and chemical technologies, combining industry knowledge with strong strategic capabilities.

Our approach is client-centered. We are known for being responsive, for communicating effectively with scientists, entrepreneurs, and investors, and for our high success rates in prosecution, opposition, and appeal cases. By working closely with our clients, we ensure their IP strategies are tailored to both protect and leverage their innovations.

Our team is diverse and multidisciplinary, including molecular biologists, bioengineers, mechanical engineers, and electrotechnical engineers. Many of our professionals are former scientists, IP examiners, or consultants, giving us a unique ability to bridge law, technology, and business. We also contribute actively to IP education, providing training in Portugal and abroad, including tutoring roles at the University of Strasbourg and the Institute of Professional Representatives before the EPO.

In addition, we offer extensive expertise in patent searching, supported by world-class databases and tools, delivering precise and actionable reports on patentability, freedom-to-operate, and infringement. With certified European patent litigators on our team, we also provide strong support before patent and arbitration courts.

At PATENTREE, we combine legal excellence, technical expertise, and strategic vision to ensure that our clients’ intellectual assets are fully protected and maximized.
