UPC turns three: statistics, milestones, and trends

Three years ago, on 1 June 2023, the UPCA entered into force, marking the launch of what is arguably the most ambitious project in European judicial cooperation in recent decades: the Unified Patent Court.

Three years ago, on 1 June 2023, the UPC opened its doors, marking the launch of what is probably the most ambitious patent dispute resolution project globally. The UPC rapidly became a center of gravity in virtually all of the multijurisdictional patent litigation campaigns filed around the world since then. Its jurisdiction covers 18 EU Member states and through its long-arm jurisdiction according to the CJEU BSH v Electrolux decision even all of the meanwhile 40 EPC Member States and thus a market which is significantly larger than the U.S. market.   

We at BARDEHLE PAGENBERG have been involved from the very beginning, we have been appearing in about 25% of all of the proceedings filed since then and we are deeply grateful for the opportunities this has created to contribute our share to the development of the system. Some exemplary landmark cases we have been involved in include:  

The 10x Genomics v. NanoString (UPC_CFI_2/2023) case complex that was filed on the very first day. It rapidly became a landmark in the Court's early history. Notably, it arose in the Pharma & Life Sciences sector, an area widely expected to adopt a cautious, wait-and-see approach toward the new system. Instead, the case brought high-stakes biotech litigation to the UPC from the outset. As the UPC's first inter partes preliminary injunction proceedings, the case required the Court to address fundamental questions for the first time, including PI requirements, claim construction, inventive step and whether amended claims could be relied upon in PI proceedings. It also produced a series of procedural firsts: the first oral hearing before the UPC (Munich Local Division), the first inter partes PI to be granted, and the first hearing before the Court of Appeal

Philips v. Belkin (UPC_CFI_390/2023), also filed on the first day. It was the first SEP-case (though the defendants did not raise a FRAND defense) and the first case on the merits that went through both instances of the UPC. In substance, the decisions issued in first instance and by the Court of Appeal clarified several important questions, such as the liability of directors for patent infringements by their companies, the proportionality of recall and destruction claims as well as the competence of the UPC in light of parallel national proceedings. Consequently, the case received widespread attention and was honored as “Impact Case of the Year 2026” by Managing IP. 

Dolby v. Beko (UPC_CFI_135/2024; UPC_CFI_477/2024). It was the first case in which the Local Division Düsseldorf issued a decision on a FRAND defense. The Local Division applied the same principles that had already been set forth in Panasonic v. Oppo and Huawei v. NetGear by the local divisions in Mannheim and Munich. In substance, the Court dismissed the FRAND defense because defendants had failed to engage in good faith negotiations and were thus found to be unwilling. Given the shortcomings in the defendants’ conduct, the Court did not have to decide the highly relevant and still open question, whether the owner of a patent that conveys market dominance, but for which no FRAND declaration has been issued (because the patent owner was not involved in the standard-setting), is subject to the FRAND obligations as set forth in Huawei v. ZTE. 

The litigation complex Amgen v. Sanofi/Regeneron (UPC_CFI_14/2023; UPC_CFI_1/2023; UPC_CFI_505/2023). It included several landmark decisions: 

  1. After Amgen lodged its infringement complaint before the Local Division Munich on Day 1 of the UPC and the counterclaim for revocation was subsequently bifurcated and combined with the standalone revocation case before the Central Division Munich, Amgen obtained a decision from the Court of Appeal which overturned the first-instance decision of the Central Division. In substance, the Court of Appeal fully maintained the validity of the patent-in-suit and issued a landmark decision, providing detailed headnotes on how to assess inventive step, sufficiency, added matter, and claim construction under the UPC framework. The case was recognized as “Europe Impact Case of the Year 2026” by Managing IP.
     
  2. Also worthy of highlighting is the landmark decision of the Local Division Düsseldorf in Sanofi/Regeneron v. Amgen setting forth, for the first time, requirements and factors for the assessment of infringement of second medical use claims. The decision was eagerly awaited by practitioners, as case law in the member states is scarce. The Local Division Düsseldorf did not simply transfer national liability concepts to the UPC but chose to develop its own multifactorial standard of liability for the infringement of second medical use claims. Based on this standard, Amgen was able to achieve a complete dismissal of Sanofi/Regeneron’s infringement action. 

Alexion Pharmaceuticals v. Amgen (UPC_CFI_124/2024). The UPC Local Division Hamburg rejected Alexion’s application for a preliminary injunction against the sale of Amgen’s biosimilar BEKEMV, thereby issuing important guidelines that the UPC must be convinced of the validity of a patent in suit with a “sufficient degree of certainty”  and that a decision on provisional measures cannot be based solely on the UPC's view of the validity of the patent in suit, but must also consider the likelihood that the EPO will revoke the patent in parallel opposition proceedings. The Court of Appeal upheld the decision and additionally elaborated on the boundaries for the correction of alleged inaccuracies in a patent claim by means of claim interpretation, and that statements by the applicant during the grant proceedings, and in particular the TBA’s endorsement thereof, can be seen as an indication of the view of the person skilled in the art at the filing date. The other panel of the Court of Appeal eventually developed a strict benchmark that applies to applications for rehearing cases because of alleged procedural defects. The case was recognized as Europe Impact Case of the Year 2025 by Managing IP. 

Ballinno v. UEFA/Kinexon (UPC_CFI_151/2024). A case particularly close to some of our hearts at BARDEHLE PAGENBERG: helping to ensure that the 2024 European Championships in Germany could proceed without patent litigation stealing the show. Just two months before kickoff, Ballinno sought a preliminary injunction based on an offside-detection patent to block the Video Assistant Referee (VAR) system at Euro 2024. The application was rejected by the Hamburg local division in time for the tournament to proceed. On the legal side, the decision clarified key questions on urgency: urgency under Rule 211.4 RoP is to be assessed on a case-by-case basis rather than by a rigid “one-month” rule, and applicants must file complete and persuasive evidence from the outset, as courts will not invite parties to cure evidentiary gaps mid-proceedings.

Let’s now turn to the current state of play in terms of statistical data. The reported figures represent a complete census of all available decisions. Given the still small number of decisions, particularly at divisional level and for the Court of Appeal, these figures are purely descriptive in nature. The population sizes are in many instances insufficient to support reliable inferential analysis or meaningful generalization.

Use of the UPC

Case distribution by Local Division 

The German Local Divisions lead the UPC's docket at both procedural levels, accounting for 70% of preliminary injunction filings and 76% of infringement main actions. Munich is the most frequently chosen Local Division in both categories. The Hague and Milan each account for 10% of preliminary injunction proceedings; The Hague and Paris have attracted 9% and 6% of infringement main actions, respectively.  

Nationality of parties in CFI proceedings 

US entities were the most frequent applicants in preliminary injunction proceedings (44%) and the most frequent defendants in standalone revocation actions (57%). German entities were the most commonly named defendants across both preliminary injunctions (33%) and infringement main actions (29%). In standalone revocation actions, Dutch and French entities took the lead as claimants (22% and 20% respectively).  

Proportion of Contracting UPC Member States for which remedies are sought (infringement main actions) 

Germany (92%) and France (89%) were covered in virtually every infringement main action. Italy and the Netherlands followed at 65% and 63%. Smaller Contracting Member States were included significantly less often, with Romania (12%) and Malta (14%) at the lower end. 

Value in dispute in CFI proceedings

The pronounced difference between median and average values across all proceedings points to a relatively small number of very high-value cases inflating the average. This underlines that parties are making use of the UPC’s unified cross-border procedures not only for ordinary disputes, but also for particularly high-value matters, such as the Amgen v. Sanofi case complex.

CFI Top technical fields (overall) – IPC class (3 digits)

Medical or veterinary science; hygiene (A61) leads across all proceeding types, followed by electric communication technique (H04) (driven substantially by standard-essential patent disputes) and furniture; domestic articles or appliances; coffee mills; spice mills; suction cleaners in general (A47), reflecting several high-profile consumer product cases.

Speed and procedure

Average duration of CFI proceedings (from filing to order/decision)

The UPC delivers preliminary injunction decisions in an average of 112 days (~3.7 months). Infringement main actions average 16.2 months and standalone revocation proceedings 14.0 months.

Success rates: CFI preliminary injunction proceedings (42 decisions)

60% of applications were granted. In those cases where they were denied, the most common reason was insufficient proof of infringement (42%), followed by invalidity being considered more likely than not (32%). Enforcement security was ordered in 35% of successful cases; 15% of grants were issued ex parte.

Success rates: CFI infringement main proceedings (84 decisions – 67 counterclaims)

Patents were maintained as granted in 52% of counterclaim proceedings, maintained in amended form in 16%, and fully revoked in 31%. Lack of patentability was the dominant revocation reason (63%), with added subject-matter accounting for 34%. Claimants succeeded on infringement claims in 44% of cases (figure affected by the revocation outcome).

Revocation rates: CFI standalone revocation proceedings (29 decisions)

In standalone revocation proceedings, patents were amended (38%) more often than maintained as granted (24%). In counterclaim proceedings, the vast majority of patents survived unchanged (52% maintained vs. 16% amended). Added subject-matter features more prominently here (45%) relative to infringement main actions (34%), whilst no insufficient disclosure was present in any standalone revocation action.

Comparison of actors:

Comparison of Local Divisions: Preliminary injunction proceedings

Munich and The Hague shared the highest grant rate1) (67%), whilst Hamburg was the fastest division at an average of just 94 days. The Hague ordered enforcement security most frequently (33% of successful cases), yet Hamburg ordered none during the reporting period.

Comparison of Local Divisions: Infringement main actions

Düsseldorf and The Hague both maintained2) patents in 71% of counterclaim proceedings; Düsseldorf recorded the highest infringement rate at 60%. Paris so far had the sharpest contrast: a 71% revocation rate, the lowest infringement rate (30%), but the shortest average duration at 14 months. Munich had a relatively high revocation rate of 47%. Enforcement security was ordered only in Munich and Mannheim (6% each).

EPO opposition proceedings vs. UPC revocation

The patent in suit faced EPO opposition proceedings as well as UPC invalidity proceedings (either sequentially or in parallel; conditional counterclaims and default judgements not included) in 15% of infringement main actions (total: 84 cases) and 41% of standalone revocation actions (total: 29 cases). The higher rate in standalone revocation cases indicates that patentees in those proceedings have so far faced coordinated challenges across multiple fora more often than for counterclaims.

The data show that there are several cases in which a patent was revoked by the EPO for added subject-matter even though it was maintained by the UPC. Therefore, there appear to be some early indications that the EPO seems to be stricter when it comes to assessing added subject matter – even though the legal standard of “direct and unambiguous disclosure” is nominally the same.

Regarding inventive step, no difference is apparent from the data even though the UPC formally relies on a holistic approach to assessing inventive step, while the EPO employs the problem-solution approach. That said, two cases illustrate that divergent outcomes on inventive step between the EPO and the UPC can occur. In proceedings concerning EP 3 435 866 (DexCom v. Abbott), the EPO maintained the patent in opposition, whereas the UPC Local Division Paris revoked it – the divergence was driven by a different reading of the same prior art document (Berman), leading to different assumed distinguishing features and a different objective technical problem. In proceedings concerning EP 2 493 466 (Sanofi v. Stada et al.), the EPO Board of Appeal (T 0136/24, June 2025) maintained the patent, while the UPC Local Division Munich fully revoked it in December 2025 – both panels applied the same legal principle (that a clinical trial nearing completion is not per se an indicator of success or failure), yet reached opposite conclusions when weighing the cumulative factual evidence regarding the skilled person's reasonable expectation of success. In both cases, the divergence appears to stem from differences in judgment rather than from the different methodological frameworks applied by the EPO and the UPC.

CoA

The Court of Appeal overturned3) 39% of first-instance preliminary injunction decisions (18 cases) and 50% of infringement decisions (6 cases). Appellants succeeded in 56% of PI appeals and 50% of infringement appeals. Average duration was 159 days for PI cases and 356 days for infringement.

Some early conclusions

In its first three years, the UPC has established itself as a fast, effective, and internationally accepted go-to forum for global patent dispute resolution.

The German Local Divisions have received the large majority of proceedings, with Munich as the most frequently chosen division. In our experience, this is driven by market dynamics and reflects the preferences of a diverse user base.

US entities were the leading claimants in preliminary injunctions proceedings and the primary targets in standalone revocation actions, underlining the Court's global reach. Proceedings were resolved swiftly: preliminary injunctions in under four months, main actions in approximately 14–16 months.

While the data show that the UPC is interesting for innovators, the validity of the asserted patents was assessed with varied outcomes. In infringement main actions, 47% of the patents are fully revoked or maintained only in amended form; in standalone revocation, that figure rises to 76%.

A very happy birthday UPC, well done so far, long live the Court!

1) Percentage rates based on small case counts should be interpreted with caution, as a single additional decision can significantly alter the reported rates.
2) The same caveat applies here.

The population size is insufficient to support reliable inferential analysis or meaningful generalization.
