The Unified Patent Court (UPC)

The Unified Patent Court (UPC) is a court common to the participating 18 EU Contracting Member States. The UPC is exclusively competent for disputes concerning the infringement or revocation of Unitary Patents and classic European patents validated in the participating countries. The UPC is a decentralized system comprising local, regional, and central divisions across Europe (e.g. Belgium has a local division in Brussels). This court exists since June 1st, 2023.

Prior to June 1, 2023, national courts were solely responsible for infringement and/or invalidity actions relating to European patents in their respective territories, leading to parallel court procedures in case infringement takes place on a pan-European level.

The UPC aims to provide a simpler and more efficient judicial system with one court having jurisdiction across all participating EU countries for all European patents and Supplementary Protection Certificates (SPC) obtained based on European patents.

During a transitional period of seven years, which may be prolonged by up to a further seven years, an infringement or revocation action based on a classic European patent may be brought before national courts or before the UPC. Patent proprietors wishing to avoid the risk of central revocation of their classic EP patents by the UPC can opt-out any of their granted EP patents and supplementary protection certificates (SPCs) from the UPC’s exclusive competence during the transitional period.

UPC - Advantages

Consolidated enforcement across multiple states

Patent proprietors no longer need to litigate the same infringement case in parallel proceedings across different national courts. A single UPC decision on validity and infringement takes effect across all participating Member States, reducing cost and eliminating the risk of conflicting judgments. However, the UPC has the downside that a revocation decision means that a single UPC judgment invalidates the patent in all participating states simultaneously, removing protection everywhere at once.

Developing European case law and legal certainty

Over time, the UPC is building a coherent body of European patent jurisprudence, eliminating the diverging interpretations that previously arose from fragmented national court systems. This predictability (which is still largely being created) benefits all parties in understanding how their patents will be enforced.

Unified remedies: injunctions and damages across borders

Patent proprietors can obtain injunctive relief and damages awards that apply uniformly across the UPC territory in a single proceeding, providing effective enforcement of valid patents without multiple litigation campaigns.

Flexible revocation proceedings for third parties

Third parties can challenge patent validity through a dedicated UPC revocation action at any time during the life of a patent, independent of the EPO opposition procedure and its time limits.

More efficient and balanced litigation system

The consolidated framework reduces overall litigation costs and provides faster and more efficient judicial procedures, creating a more balanced system serving both patent proprietors (clearer enforcement) and third parties (accessible revocation routes).
