Unified Patent Court (UPC)

The Unified Patent Court (UPC) has transformed European patent litigation, creating a central forum for patent enforcement and validity challenges across participating EU Member States. As UPC case law continues to develop, businesses and practitioners closely monitor decisions that shape litigation strategy, procedural practice, and the interpretation of substantive patent law.

This category tracks key UPC developments, including infringement actions, revocation proceedings, preliminary injunctions, procedural rulings, and judgments from both the Court of First Instance and the Court of Appeal. Our contributors analyse significant decisions and emerging trends, highlighting their practical implications for patent owners, challengers, in-house counsel, and litigation teams.

For professionals involved in European patent disputes, portfolio management, or freedom-to-operate assessments, this section provides timely commentary and expert analysis of the latest UPC decisions and the evolving body of UPC case law.
