UPC-Agreement : the Unitary Patent & the Unified Patent Court

According to the European Patent Office [link], the Unitary Patent and the Unified Patent Court are the building blocks that will supplement and strengthen the existing centralised European patent granting system.

They are meant to offer users of the patent system a cost-effective option for patent protection and dispute settlement across Europe. The new system starts on 1 June 2023.

General Overview

The introduction on June 1, 2023, of the European patent with unitary effect is accompanied by the creation of the Unified Patent Court (UPC) hearing certain actions relating to this new type of patent and some other similar titles. For an overview, follow this link

The transitional period and the Opt-Out

During a transitional period of (at least) seven years, an action for infringement or revocation of a European patent without unitary effect (or an SPC based on such patent) may be brought before a national court or the UPC, at the option of the claimant.

However, the patent owner can avoid the jurisdiction of the UPC, and in particular the possible invalidation of his patent for all UPC States by a single court decision, thanks to an “opt-out” to be filed as soon as possible. The benefit of the “opt-out” applies to the patent in question (and, if applicable, to the SPC based thereon) for its entire term of validity.

To find out more about how the “opt-out” mechanism works, its benefits and risks and how to activate it, follow this link

The entry into force of the system calls for an overview of:

  • the main rules that will determine the “internal” competences among the EU Member States parties to this agreement (“UPC States”). For more information, follow this link
  • the main rules that will determine its “international” jurisdiction, i.e. in relation to EU Member States that have not ratified the UPC Agreement, and “third” (non-EU) States. For more information, follow this link
