Wake up to the Sun! Germany Deposits Instrument of Ratification of the UPC Agreement

By Matthew Howell, Partner and Will Morgan, Partner

Germany has today deposited its instrument of ratification of the UPC Agreement, triggering the start of the Sunrise Period for the Unified Patent Court (UPC).

Sunrise Period begins on 1 March 2023

The Sunrise Period will begin on 1 March 2023 and 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.

UPC and UP come into effect on 1 June 2023.

The UPC Agreement will come into effect on 1 June 2023 (the first day of the fourth month after Germany’s ratification). From that date it will be possible to obtain Unitary Patents and to bring actions at the Unified Patent Court in respect of European patents that have not been opted out.

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.
