Why can a single effective judgment of the Unified Patent Court (UPC) simultaneously constrain multiple European countries after its implementation, and what is the risk exposure of Chinese companies

The binding scope of the effective judgment of the Unified Patent Court (UPC) covers all EU member states that have ratified the Agreement on the Unified Patent Court. Currently, there are 17 countries plus one candidate country. Chinese companies may be trapped in multiple markets by a single judgment if they sell, exhibit or use overseas warehouses in any of these countries. The risk exposure is not determined by the amount of compensation awarded, but by the immediacy and cross-border enforcement of the injunction.

Why can a single verdict simultaneously govern more than ten countries

UPC is not just another ordinary court newly established by the European Union. It is a supranational judicial institution established under the Unified Patent Court Agreement (UPCA), which consolidates European patent infringement lawsuits that were previously scattered among national courts into one system. As of 2026, the member states that have ratified and are bound by the agreement include Germany, France, Italy, the Netherlands, Belgium, Sweden, Denmark, Finland, Austria, Portugal, Spain, and a total of 17 countries. There are also countries that have signed but not ratified the agreement. UPC's territorial jurisdiction is divided into central courts, local courts, and regional courts. First instance judgments automatically take effect within the territory of these countries and do not require separate applications for recognition and enforcement in each country. This is completely different from the situation faced by Chinese companies in the past - in the past, when they were sued in Germany, the judgment was usually only enforced within Germany, and the Netherlands and Italy had to file separate cases.

There are two types of patents involved: traditional European patents (authorized by the European Patent Office (EPO) and effective in various countries) and unitary patents. Unified patents are naturally under the exclusive jurisdiction of UPC, while traditional European patents may be subject to opt in or opt out by patent owners to enter UPC jurisdiction. In practice, many Chinese companies' European patent layouts are traditional European patents left over from history, without opt out, resulting in passive falling into the UPC range. We generally recommend that customers conduct a rights status inventory within 2026, so as not to wait until they receive a lawsuit and realize that they have not exited the window.

The ban is an automatic cross-border measure, not a case of winning against one country

The most lethal remedy of UPC is the cross-border ban. Once the court determines that infringement is established, it may issue an injunction covering all bound member states, prohibiting imports, sales, offers for sale, use, and inventory. For cross-border e-commerce sellers, this means that a judgment by a German court may directly result in the same ASIN being simultaneously delisted from sites in France, Italy, and Spain, and goods in overseas warehouses may also be seized. In terms of compensation, UPC can award damages, return profits, reasonable licensing fees, and support temporary measures and evidence preservation. The review criteria for temporary injunctions vary slightly among different courts, but the overall pace is faster than that of federal courts in the United States. From filing to hearing temporary measures, it often takes several months, depending on the court schedule and the complexity of the case.

Many customers may think 'sell first, wait for the other party to sue' when they first encounter it. Under the UPC system, this approach is costly because once the ban is implemented, sales will be suspended in multiple countries, and peak season stocking will directly become unsold inventory. Refer to the explanation on risk management in the European market in the overseas intellectual property section, the core logic is that the infringement risk in Europe is a "one-time exposure to multiple countries", not cumulative by country.

UPC and EUIPO are two separate systems, don't confuse them

Sellers often confuse UPC with the European Union Intellectual Property Office (EUIPO). EUIPO manages the authorization and invalidation of EU trademarks (EUTM) and registered EU designs (RCD), while UPC manages patent infringement and patent invalidation lawsuits. The cross-border rights protection of trademarks and designs still go through the EUIPO invalidation procedure or national courts, and do not belong to UPC. But there are intersections between the two: if the appearance design involves both technical functions, it may be dragged into patent disputes; If the defendant counterclaims the patent in a trademark infringement lawsuit, it may also trigger UPC jurisdiction. For enterprises doing business in multiple European countries, the risks of trademarks, designs, and patents should be evaluated separately, and not just focused on one aspect. The relevant cross-border layout can refer to the intellectual property legal services of the United States and the European Union.

Invalid countermeasure: UPC Central Court is the main battlefield

After being sued, the defendant's common countermeasures are to file a counterclaim for patent invalidity with the UPC Central Court, or to file an objection/invalidity with the EPO. The patent invalidation judgment of UPC in the first instance also has cross-border effect, which can cancel the involved patent in all bound countries at once. But pay attention to the timeline: there is a deadline requirement for filing counterclaims in UPC litigation, and if it is delayed, the court may first deal with the infringing part. In addition, the EPO objection procedure is only open within 9 months after authorization, and after expiration, it can only be invalidated by EPO or other countries, with increased costs and cycles. We usually advise clients to conduct invalid searches simultaneously during the warning letter stage, fixing the evidence in the front end instead of waiting for the court to temporarily search for prior art.

The 'urgency' requirement of the ban may disappear if delayed

UPC's temporary measures require applicants to demonstrate urgency. If the patentee is aware of infringement and fails to take action for a long time, the court may consider it not urgent and dismiss the temporary injunction. Conversely, the defendant can also use this point as a defense. In practice, some companies do not respond, evaluate, or continue to distribute goods after receiving a warning letter. As a result, the other party applies for temporary measures on the grounds of "continuous infringement and expanded damage", making it easier for the court to determine urgency. Providing a substantive response within 30 days of receiving a letter is a common recommendation among many European lawyers, not a mandatory rule, but it can significantly reduce the passive situation. For comparison of procedures involving multiple European countries, please refer toIntellectual property legal services in other countries.

Costs and guarantees: Cross border bans are not free

The cost structure of UPC litigation is different from domestic litigation in various countries. The court fees are divided according to the disputed amount, plus the legal fees of both parties. For a medium complexity cross-border infringement lawsuit, the total cost is usually in the tens of thousands of euros, depending on the technical field, amount of evidence, and whether to appeal. Temporary injunctions usually require the applicant to provide a guarantee, the amount of which is determined by the court, to cover the losses incurred by the defendant due to the erroneous injunction. For the defendant, if the injunction is revoked, they can claim guarantee compensation, but it is not easy to prove the loss. As defendants, Chinese companies need to reserve costs for inventory handling, channel breaches, and platform compliance in addition to litigation costs.

Where exactly does the risk exposure of Chinese enterprises fall into

The first is the product side: technology-based products sold simultaneously in multiple European countries, especially in consumer electronics, home appliances, and new energy accessories LED、 The communication module has a high probability of being covered by UPC bans. The second is the channel side: platforms such as Amazon, eBay, OTTO, etc. usually quickly take down and may freeze account funds after receiving bans. The third is the subject side: if the Chinese parent company is directly the defendant, the judgment can be enforced against its European assets; If sold through a European subsidiary, the parent company may also be added. The fourth is the supply chain side: contract factories and overseas warehouse service providers may be required to stop processing the goods involved. For companies targeting the European market in 2026, it is recommended to create a list of at least which SKUs, sites, and warehouses will be affected once the UPC ban is implemented. This is much more useful than putting out fires afterwards.
