UPC News – The Sunrise Period Begins Today

By Matthew Howell, Partner

The UPC Sunrise Period begins today, 1 March 2023, following Germany’s deposit of its instrument of ratification of the UPC Agreement on 17 February 2023.

The Sunrise Period will last for three months.

During this period, European patent holders and applicants can opt their European patents and European patent applications out of the exclusive jurisdiction of the UPC before the Court opens for business on 1 June 2023.

How can HLK Assist?

HLK offers an opt out service to help applicants and proprietors of European patent rights reduce the administrative burden of opting out their rights.

If you are interested in this service, or if you have any queries regarding opting out or any other aspect of the Unitary Patent and Unified Patent Court system, please contact our team at
