UK will not participate at the Unitary Patent Court System.
Paragraph 5 of the UK’s most recent negotiating objectives reads:
“It is a vision of a relationship based on friendly cooperation between sovereign equals, with both parties respecting one another’s legal autonomy and right to manage their own resources as they see fit. Whatever happens, the Government will not negotiate any arrangement in which the UK does not have control of its own laws and political life. That means that we will not agree to any obligations for our laws to be aligned with the EU’s, or for the EU’s institutions, including the Court of Justice, to have any jurisdiction in the UK.”
Since The CJEU already made it clar that the UPC Agreement requires to respect EU law and the CJEU’s jurisdiction, this means the end of UK’s will to participate in the UPC and maybe it means the end of the UPC at all.
