Overview
The Unitary Patent system (also known as the European patent with unitary effect) was introduced to create a streamlined patent protection mechanism across participating European Union (EU) member states. Supported by Regulation (EU) No 1257/2012 and Regulation (EU) No 1260/2012, as well as the Agreement on a Unified Patent Court (UPC), this system officially entered into force on June 1, 2023. By filing a European patent through the European Patent Office (EPO) and subsequently requesting unitary effect, patent proprietors can enjoy uniform protection and enforcement in all participating EU countries, reducing administrative burdens.
The Unitary Patent coexists with existing national patent systems and the traditional European patent bundle validation system. Once granted by the EPO and registered for unitary protection, the Unitary Patent is administered centrally, with renewal fees paid annually to the EPO.
EU Member States
The following 18 EU member states currently participate in the Unitary Patent system: Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Romania, Slovenia, and Sweden.
Other EU countries may join the system upon ratifying the UPC Agreement. The Unitary Patent operates alongside existing national systems and the traditional European patent system.

Under the Unitary Patent scheme, patents are granted by the European Patent Office following the usual examination procedures outlined in the European Patent Convention. Upon grant, the patent proprietor may request unitary effect within a limited time frame.
- Requirements: The applicant must first secure a European patent from the EPO, then submit a request for unitary effect to obtain uniform coverage in participating EU states.
- Renewal Period: A Unitary Patent remains in force for up to 20 years from the filing date, subject to annual renewal fees payable to the EPO.
- Examination: The EPO conducts both formal and substantive examinations of European patent applications; once granted, the single request for unitary effect replaces the need for individual national validations.
- Member State Implications: Infringement and revocation proceedings are addressed before the Unified Patent Court, which holds jurisdiction across member states that ratified the UPC Agreement.

Understanding the Unitary Patent
Effective since June 1, 2023, the Unitary Patent introduces a new way to obtain patent protection across much of the EU with a single application.
