Litigation

We are proud to announce that Inventa has been recognized in the annual Leaders League ranking of the best firms in Portugal. This year, we have been distinguished as a Leading Firm in both “Trademark Prosecution” and “Patent Prosecution,” and as a Recommended Firm in the “IP Litigation” category. These distinctions reflect outstanding contributions of our team members, including Vítor Palmela Fidalgo, Vítor Sérgio Moreira, João Pereira Cabral, and Joana Fialho Pinto.

With deep expertise in intellectual property law and a role as an expert at the UPC Mediation and Arbitration Centre, Vitor Palmela Fidalgo shares the challenges and priorities of advising clients on IP matters both locally and internationally, and explains how the Unified Patent Court (UPC) is shaping patent litigation, enforcement, and broader IP trends in Portugal and across Europe.

Artificial intelligence (AI) is the ultimate buzzword at the moment. But from a patent-based perspective, it is more than just the new fad: it is a pointer to technological developments and signals what consumers should expect from new products coming to the market in the near future.

When it all started

We are proud to share that Inventa has once again been recognised in the 2025 edition of the IAM Patent 1000, a leading guide dedicated to identifying top patent professionals worldwide. In the Prosecution category for Portugal, Inventa was highlighted for its continued excellence and expertise in the field.
