UPC Litigation

Our European Patent Attorneys and Attorneys-at-law, registered as UPC representatives, act in this capacity for both claimants and defendants in all types of actions falling within the jurisdiction of the Court: infringement actions, revocation actions, actions for declarations of non-infringement, provisional measures, seizures, claims for damages, etc.
Thanks to their dual technical and legal expertise, our team offers an integrated and tailored approach, perfectly aligned with the specific challenges of each case.

The Unitary Patent system offers the unique possibility to obtain, enforce and invalidate patents in all EU member states in central proceedings at the Unified Patent Court (UPC). The potential rewards for patent proprietors are substantial, but so are the associated risks.

At CASALONGA, we have been actively involved in the UPC’s development for many years. Our team – composed of European patent attorneys and experienced litigators – has advised legislators, taken part in working groups, and thoroughly prepared for the new system.
Most of our attorneys are qualified to act before the UPC and are proud to represent clients before the Court, ensuring full compliance and seamless representation.

Integrated Legal & Technical Expertise

We strategically pair our attorneys-at-law with European patent attorneys on each case to deliver both legal precision and deep technical insight. With teams based in France and Germany, we tailor our approach to each case’s jurisdictional and technological complexity.

Mastery of UPC Procedure

Our team includes professionals who contributed to shaping the UPC and its Rules of Procedure. This insider knowledge ensures we can navigate the procedural nuances of the central, local, and regional divisions with confidence and precision.

Local Presence Where It Matters

With offices in Paris, Munich, and Düsseldorf, we are ideally positioned to represent clients before the most active divisions of the UPC.

What is the UPC?

UPC in a nutshell

  • - The UPC has exclusive jurisdiction to decide on infringement and validity of European patents and Unitary patents: the UPC replaces the national courts for European patents.
  • - During a transitional period of 7 years, it is still possible to choose either the UPC or the national courts.
  • - Opt out: during the transitional period, it is possible to register, for a specific European patent application or a specific European patent, a declaration that only national courts shall be competent for this European patent application or European patent, during the entire life of the patent.
  • - The opt out may be withdrawn at any time under certain conditions.

The UPC system is undeniably complex, with a multitude of interconnected elements. Our UPC visual guide breaks the complexity down and provides an easy-to-understand graphic overview over all important proceedings, including relevant timelines.
