The Unified Patent Court (UPC) is a new supranational court with jurisdiction over patent disputes in EU member states that have ratified the UPC Agreement. Operational since June 2023, the UPC was created to address a fundamental problem with European patent litigation: the cost and inefficiency of parallel national proceedings. Before the UPC, enforcing a European patent against infringement across multiple EU states required separate litigation in each national jurisdiction (different courts, different procedural rules, different evidentiary standards, and the real risk of inconsistent decisions on the same patent and the same alleged infringement in different countries). The UPC provides a single forum for pan-European patent enforcement and validity proceedings, with a single decision covering all participating member states.
The UPC has jurisdiction over two categories of European patents: Unitary Patents, which are automatically subject to UPC jurisdiction with no possibility of opt-out; and European bundle patents (European patents validated nationally in UPC member states) unless a valid opt-out has been filed before UPC proceedings are commenced. The opt-out for European bundle patents was available from sunrise registration before the UPC opened, and remains available during the seven-year transitional period ending approximately in 2030. After that, European bundle patents in participating states will be subject to UPC jurisdiction regardless of opt-out status.
The UPC consists of a Court of First Instance and a Court of Appeal. The Court of First Instance has three types of divisions. The Central Division, which sits in Paris and Munich (with a sub-registry for certain technology classes previously assigned to London), handles revocation actions filed centrally and declarations of non-infringement. Local Divisions, established in participating member states that have requested them, handle infringement actions filed in the territory where the infringement occurred or where the defendant is domiciled. Regional Divisions serve groups of member states that have established joint divisions: the Nordic-Baltic Regional Division covers Sweden, Estonia, Latvia, Lithuania, and Finland.
The Court of Appeal is located in Luxembourg and hears appeals from all first-instance divisions. It provides a uniform appellate standard across the UPC's jurisdictions, ensuring that divergent interpretations of patent law at the local level can be corrected and harmonised. Decisions of the Court of Appeal on questions of EU law may be referred to the Court of Justice of the EU.
Infringement actions are filed at the local or regional division where the infringement occurred or where the defendant is domiciled. The UPC's procedural rules are designed for speed: the default target for first-instance proceedings is a written procedure and oral hearing within 12 months of filing. This is significantly faster than most national patent court systems in Europe, where first-instance proceedings typically take 2 to 5 years.
Revocation actions can be filed at the Central Division or as a counterclaim in infringement proceedings at any division. The UPC applies the European Patent Convention's validity standards, supplemented by the court's own procedural rules. A central revocation action that succeeds at the UPC revokes the patent across all participating states simultaneously, the same centralised risk that applies to Unitary Patents through the central division, and which applies to opted-in European bundle patents through the same mechanism.
The UPC also has powers to grant pan-European injunctions, orders for preservation of evidence, and orders for inspection of premises, remedies that in the pre-UPC era would have required separate applications in each national jurisdiction. This enforcement arsenal significantly increases the leverage available to patent holders against infringers operating across multiple EU markets.
The opt-out decision is one of the most strategically important patent management questions for any company with a European patent portfolio in the transitional period. Filing an opt-out excludes a European bundle patent from UPC jurisdiction, preserving national court jurisdiction only. Once filed, the opt-out can be withdrawn (the patent re-opts in), but only if no national court proceedings have been commenced, and once any UPC action has been brought, the opt-out right is lost for that patent.
The opt-out decision depends on each patent's risk profile. For valuable patents in technically contested fields where invalidity attacks are likely, opting out preserves territorial fragmentation: an attacker must pursue invalidity in each national court separately, increasing cost and risk. For patents where the commercial priority is enforcement rather than invalidity defence, remaining in (or opting in for previously opted-out patents) enables pan-European enforcement through a single UPC action.
The opt-out decision is fact-specific for each patent. For patents in technically competitive fields where well-resourced parties may mount invalidity attacks, opting out preserves territorial fragmentation as a defensive strategy. For patents covering commercially significant technology where the priority is efficient pan-European enforcement, remaining in the UPC system provides enforcement efficiency that national litigation cannot match. We advise on the opt-out decision based on your specific portfolio, competitive landscape, and the risk/benefit profile of each patent.
The UPC has a Court of First Instance (with a Central Division in Paris and Munich, plus local and regional divisions across member states) and a Court of Appeal in Luxembourg. Infringement actions are filed at the relevant local or regional division. Revocation actions and declarations of non-infringement are handled by the Central Division. The Court of Appeal provides a uniform appellate standard across the full UPC jurisdiction.
The UPC targets first-instance proceedings within 12 months of filing, significantly faster than most European national patent courts, where first-instance decisions typically take 2 to 5 years. This speed is a significant advantage for patent holders seeking injunctive relief against ongoing infringement. It is also a factor to consider for defendants, who will face an accelerated timetable with limited flexibility to delay proceedings.
Yes. The UPC can grant pan-European injunctions covering all participating member states in a single order, without the need for separate applications in each national jurisdiction. It can also grant provisional measures (preliminary injunctions, orders for preservation of evidence, and inspection orders) pending the outcome of full proceedings. This enforcement arsenal significantly increases the leverage available to patent holders and the potential exposure faced by defendants compared to the pre-UPC national litigation environment.
