Unitary Patent System

Regulations (EU) No. 1257/2012 and No. 1260/2012 of December 17, 2012 implementing enhanced cooperation in the area of the creation of unitary patent protection set up the European Unitary Patent System. These regulations entered into force on January 20, 2013 and are applicable since June 1, 2023 which is the entry into force of the Agreement on a Unified Patent Jurisdiction establishing the Unified Patent Court.

To date, 17 Member States have ratified the UPC Agreement (including the 3 Member States with the highest number of European patents in force in 2012: Germany, France and Italy). It is expected that further Member States will ratify the UPC Agreement in the coming years.

The unitary patent system makes it possible to get patent protection in up to 24 EU Member States by submitting a single application with the European Patent Office, thus simplifying the procedure and making it more affordable for applicants.

The Unified Patent Court (UPC) is an international court established by the participating EU Member States to deal with infringement and validity cases of unitary patents as well as European patents, thus eliminating costly parallel proceedings and increasing legal certainty. The unified patent jurisdiction will consist of a first level court in Paris (with a section in Munich) and a court of appeal in Luxembourg, as well as local divisions in several countries. From June 1, 2023, and for a transitional period of at least seven years, national courts will continue to have concurrent jurisdiction for "classic" European patents and supplementary protection certificates.

 The UPC's Court of Appeal and Registry are based 1, rue du Fort Thüngen, L-1499 Luxembourg, in the immediate vicinity of the Court of Justice of the European Union and the European Public Prosecutor's Office, thus reinforcing Luxembourg's position as the European Union's judicial center.

Priority

Priority registrations are permitted in Nigeria.

The application for priority registration must be made within 12 months of the earlier application in the convention country. The applicant must furnish the Registry with a copy of the earlier application within a 3-month period after filing in Nigeria. Once completed, the registration in Nigeria equates to an application made in the convention country of origin.
