What is the structure of the Unified Patent Court?

The UPC will consist of a decentralised Court of First Instance, with local and regional divisions located in the contracting Member States, a central division and a common Court of Appeal seated in Luxembourg. The Registry will be set up at the seat of the Court of Appeal. The training centre for judges will be located in Budapest; the patent mediation and arbitration centre will be located in Lisbon and Ljubljana.

The UPC panels will sit in a multinational composition and consist of both legally and technically qualified patent judges. The procedure is designed in a way that judgments at first instance can be expected within approximately one year of filing the action.
