Unified Patent Court stopped by German Constitutional Court!

On March 20, 2020, the German Federal Constitutional Court (Bundesverfassungsgericht) issued its decision that the Act of Approval to the Agreement on a Unified Patent Court to confer sovereign powers on the Unified Patent Court is void, because - although the Parliament (Bundestag) unanimously approved the Act by the 35 members present - it did not approve the Act with the required "qualified majority" of 2/3 of all members.

Importantly, the Court's decision rejected all other objections to German ratification in the Complaint, saying, in paragraph 91, "Otherwise it [the Complaint] is inadmissible."

A press release summarizing the findings of the court can be found here.

Consequences of this decision:

  • The German ratification is still missing and the Unitary Patent and Unified Patent Court system cannot start without it.
  • Whether the government is making a new attempt for ratification can currently not be foreseen. Even if the ratification process is started again, it remains uncertain whether it will achieve the required two-thirds majority in both houses - Parliament (Bundestag) and Federal Council (Bundesrat).
  • After the UK recently announced that it no longer intends to be part of the Unified Patent Court System, this certainly is a severe setback for the project of the Unified Patent Court and hence the whole Unitary patent system.
  • For now, the UP/UPC project is stopped and it is currently not foreseeable for how long.

Update regarding COVID-19 and operations at Kuhnen & Wacker

As we continue to monitor the current COVID-19 situation in Germany and globally, we would like to update you on Kuhnen & Wacker operation business.

At the present time, Kuhnen & Wacker is operating business as usual and we will continue to attend to client needs.
Moreover, we have respective contingency plans in place for any disruption that may occur in our firm.

At Kuhnen & Wacker, the health and safety of our staff and their families are our priority, so we have implemented additional measures to help reduce the spread of the virus.
In addition, should any of our staff be required to work remotely, we have a secure IT system in place to ensure business continuity.

Situation with the Patent Offices:

  • The European patent office (EPO) announced that time limits expiring on or after March 15, 2020 are extended for all parties and their representatives to 17 April 2020. In accordance with Article 150(2) EPC this applies also for international applications under the PCT. The above period may be further extended by the publication of another notice if the dislocation extends beyond the aforementioned date.
    For more information, please see here
  • The German Patent and Trademark Office (DPMA) informed recently that in response to the corona situation all time limits set by the Office are generally extendable by request. However, legally determined (statutory) time limits are, in principle, not extendable. However, a Restitution-in-Integrum (Reinstatement) could be requested which is then decided on a case-by-case basis.
    For more information, please see here.
  • The EUIPO (European Union Intellectual Property Office responsible for managing the EU trade mark and the registered Community design) has taken a similar measure. The Executive Director of the EUIPO announced that they would be "extending all time limits expiring between 9 March and 30 April, that affect all parties before the Office to 1 May 2020".
