UPC Strategy in Milan: Central Division Forum Choice, Timing, and Opt-Out Guide for Italy-Based European Patent Disputes

The Unified Patent Court has reshaped the strategic landscape for European patent disputes, and Italy now occupies a far more influential position within that system. With Milan serving as part of the UPC’s central division structure, patent owners, challengers, in house legal teams, and external counsel need to think more carefully about where to file, how quickly to act, and whether a European patent should remain within UPC jurisdiction or be opted out.

There is no universal answer. The right approach depends on the strength of the patent, the commercial footprint of the dispute, the urgency of enforcement, the value of cross border relief, and the level of risk a business is prepared to accept. The aim is not simply to choose a court, but to choose the forum and sequence that best support the broader commercial objective.

Features of new UPC 

The Unified Patent Court (UPC) is divided into several locations to ensure effective coverage across the entire territory of the European Union. The structure includes three Central Divisions located in Paris, Munich, and, since June 2024, Milan. These central divisions handle the main and most complex cases.

In addition to the Central Divisions, there are several Local and Regional Divisions distributed across the various Member States. Local Divisions are located in cities such as Vienna, Düsseldorf, and also Milan, among others. Each Local Division handles patent disputes that primarily involve companies and individuals from its own country.

Composition and Nationality of Judges

The UPC is composed of judges from various EU Member States, reflecting the Union’s legal and cultural diversity. The composition of the court includes both legally qualified judges, who are legal experts with deep knowledge of patent law, and technical judges, who are specialists in the various technical and scientific fields relevant to patents.

Among the judges, a significant number are of Italian nationality. The presence of Italian judges not only in the Local Divisions but also in the Central Divisions ensures that the Italian judicial system is well represented, facilitating the understanding of local specificities and contributing to the consistency of decisions at the European level.

Types of Judges: Legal and Technical

The UPC operates with a hybrid system that includes both legal (professionally qualified) judges and technical judges. Legal judges are legal professionals with specific experience in patent matters, while technical judges are European Patent Attorneys—specialized in patents—with expertise in scientific and technological fields. This combination ensures that the court’s decisions are based not only on a solid interpretation of the law but also on a thorough understanding of the technical aspects of the patents under examination.

Languages and Applicable Law

The UPC operates primarily in three languages: English, French, and German. However, for Local Divisions, it is possible to use the official language of the country in which the division is located. As for applicable law, the court applies both European law and the national law of the Member States, ensuring a harmonized and consistent approach to resolving patent disputes.

Who May Represent Parties

Lawyers and certified European patent attorneys (patent section) may represent parties before the UPC, provided they have completed a specific qualification course, the European Patent Litigator certification. This selection ensures that only qualified professionals can represent the parties, thereby maintaining a high level of expertise and professionalism in the proceedings.

Why Milan Matters Now

The UPC is built around local divisions, regional divisions, a central division, and a Court of Appeal. That structure matters because venue is not just an administrative detail. It can influence the pace of proceedings, the tactical pressure available to each party, the scope of remedies, and the overall shape of the dispute. Milan’s role in the post Brexit allocation of central division responsibilities has therefore elevated Italy from an important national venue to a more visible part of the European patent litigation map.

That shift is especially relevant for high value disputes, including matters in the pharmaceutical and life sciences sectors. For multinational businesses, Milan is now part of strategic forum planning rather than a peripheral consideration. A case heard within the UPC framework may affect several participating markets at once, which means decisions about filing, settlement, and defence must be made with a wider territorial lens.

Forum Choice After Milan

After Milan’s rise within the UPC framework, the core question is no longer simply whether to litigate in Europe, but where a dispute can be shaped most effectively: before the UPC or before the Italian national courts. The UPC offers the possibility of a single decision with effect across multiple participating states. That can materially change settlement leverage where infringement spans several countries, supply chains are cross border, or commercial pressure needs to be applied quickly and broadly.

Italian courts remain highly relevant. They may be the better choice where the dispute is concentrated in Italy, where a party prefers narrower territorial exposure, or where domestic procedural familiarity offers a strategic advantage. In practical terms, forum selection should be guided by factors such as the desired scope of injunctions, speed to interim and final relief, exposure to central revocation risk, language and procedural demands, likely costs, and the degree of predictability a party believes it can achieve.

Milan should therefore be seen as part of a larger forum choice toolkit. It is important, but not automatic. In some disputes the UPC will provide the stronger route; in others, Italian national litigation will remain the more controlled and commercially proportionate option.

Enforcement Timing & Litigation Sequencing

Timing has become more important under the UPC because the system is designed for concentrated and relatively fast moving proceedings. Early action can create significant commercial pressure, particularly where a product launch, expansion plan, licensing milestone, or competitive market entry is imminent. A claimant that files first may be able to shape the narrative of the case, define the initial procedural posture, and force the other side into a defensive response.

At the same time, validity strategy must be considered from the outset. A party pursuing infringement needs to be prepared for a rapid validity challenge, while a potential defendant may wish to consider whether an early revocation strategy can shift leverage or limit the claimant’s momentum. This is especially important in high value sectors such as life sciences, complex technology, and SEP related disputes, where litigation strategy is often closely tied to licensing and market timing.

Delay can be costly. It may reduce flexibility, increase the chance of parallel proceedings, and allow the opposing party to seize tactical control through a defensive filing or an application for interim relief. Sequencing is therefore not a procedural afterthought. It is a central strategic lever that should be mapped before the dispute escalates whenever possible.

Opt Out Strategy for European Patents

An opt out removes a European patent from UPC jurisdiction, provided the patent remains eligible and no UPC action has already been started. During the transitional period, this remains one of the most important strategic choices available to patent proprietors. It allows rights holders to keep infringement and validity disputes in national courts rather than expose the patent to UPC wide adjudication.

The trade off is clear. Remaining inside the UPC may allow broader territorial enforcement and stronger cross border leverage. But it also exposes the patent to central revocation, meaning a single successful attack can have system wide effect across participating states. For that reason, many businesses treat the opt out decision as a risk allocation exercise rather than a mere procedural election.

Opting out may be sensible for crown jewel patents, assets with known validity vulnerabilities, or portfolios where tighter defensive control matters more than broad enforcement reach. Staying in the UPC may be more attractive for patents that are commercially important, technically robust, and likely to be enforced against multi country infringers. In most portfolios, the best answer is not a blanket rule but segmentation: different patents should follow different strategies depending on value, vulnerability, geography, and business use.

Timing is critical. An opt out should be considered early and supported by clean ownership records, complete internal coordination, and a clear understanding of whether any UPC filing by another party could close the window. Once a UPC action is underway, strategic flexibility may narrow significantly.

Practical Checklist for Businesses

When an opt out may be worth considering. An opt out is often attractive where a patent faces meaningful revocation risk, where the business wants tighter control over forum selection, or where national litigation is commercially sufficient. It can also make sense for especially valuable assets that the owner is unwilling to expose to a single central validity challenge.

When UPC litigation may be the stronger option. The UPC is often most compelling where pan European relief matters, infringement stretches across several participating states, or speed and leverage are commercially decisive. It can also be powerful where the patent is considered robust enough to withstand central scrutiny and where a coordinated enforcement campaign is likely to produce settlement pressure.

When Italian national courts may be preferable. National litigation may be the better fit where the dispute is primarily Italy based, where narrower risk is desirable, or where the business wants the familiarity and contained exposure of a domestic forum. This can be particularly sensible if Italian relief alone is enough to solve the commercial problem.

Questions to ask before filing or opting out. How important is cross border relief? How strong is the patent if central validity is tested? Is speed more valuable than risk containment? Are there parallel negotiations, supply arrangements, or disputes in other jurisdictions that could be affected by the chosen forum? Does the portfolio contain patents that should be treated differently from one another?

Ultimately, forum choice should be made patent by patent and dispute by dispute, not through a one size fits all policy. A short strategic review before filing, enforcing, or opting out can often prevent avoidable mistakes and improve leverage from the outset.

Conclusion

Milan’s increased importance within the Unified Patent Court framework has made European patent forum choice more strategic, more nuanced, and more commercially significant. Businesses can no longer treat the UPC as a simple alternative to Italian national litigation. The right route depends on the patent, the enforcement objective, the revocation risk, and the wider business context.

In some cases, the UPC will offer the strongest path to fast, cross border relief. In others, Italian national courts or a carefully timed opt out will better preserve control and reduce exposure. The key is to assess the dispute early, align litigation planning with business goals, and make forum decisions deliberately rather than reactively.
