The UK Government has finally confirmed that it wants to remain part of the Unified Patent Court (UPC) Agreement after the UK leaves the EU. However, there is no indication yet as to how EU designs and trade marks will be handled after the UK leaves the EU.

 

The future relationship between the United Kingdom and the European Union: 151. The UK has ratified the Unified Patent Court Agreement and intends to explore staying in the Court and unitary patent system after the UK leaves the EU. The Unified Patent Court has a unique structure as an international court that is a dispute forum for the EU’s unitary patent and for European patents, both of which will be administered by the European Patent Office. The UK will therefore work with other contracting states to make sure the Unified Patent Court Agreement can continue on a firm legal basis.
