On 16 September 2026 the Unified Patent Court in Munich issued an injunction against Netflix. The order extends the effect of a UPC injunction to all 18 participating Member States without requiring the plaintiff to post enforcement security. Netflix must immediately cease offering the contested streaming software in those jurisdictions. The ruling clarifies the discretionary nature of security under Article 31 of the UPC Agreement.

Full News Breakdown

DivX brought a patent infringement action before the UPC, alleging that Netflix’s streaming platform incorporated the patented method for frame‑jump navigation. The Munich division examined both the validity of the DivX patent and Netflix’s request for enforcement security, ultimately granting a cross‑border injunction.

• Case Name: DivX v Netflix

• Applicant/Plaintiff Arguments: DivX claimed Netflix’s software embodied the patented method and sought a pan‑EU injunction.

• Respondent/Defendant Arguments: Netflix contested the patent’s validity and asked that DivX provide enforcement security.

• Court's Reasoning: The panel affirmed the patent’s validity, found infringement, and held that security is discretionary, not mandatory.

How Does This Affect You?

Practitioners previously faced uncertainty about whether a UPC injunction could automatically extend across all participating Member States without a security requirement. The court now confirms that cross‑border injunctions are permissible and that the plaintiff bears the burden of posting security only at the court’s discretion. Rights‑holders can enforce pan‑EU bans more readily, while defendants face heightened exposure to immediate market‑wide prohibitions. The analysis below addresses three audience groups.

For Lawyers & Advocates

• Pending UPC infringement actions now present a concrete risk of an immediate EU‑wide ban, making a multi‑state injunction viable under the Agreement.

• Client pleadings that incorporate a detailed analysis of Article 31 reflect the discretionary nature of security and influence cost‑allocation and settlement calculations.

• Licensing and settlement agreements that contain a clause triggering automatic suspension of the disputed feature across all participating states align with the potential effect of a UPC injunction.

• The Munich decision serves as precedent for arguments concerning the imposition of security in future UPC proceedings, illustrating the panel’s reasoning on discretionary enforcement.

• The reduction of a procedural hurdle shifts the focus to substantive validity challenges and rapid compliance planning.

For Law Students

The judgment illustrates how the UPC balances patent enforcement with procedural safeguards in the internal market.
It hinges on the discretionary nature of enforcement security under Article 31 of the UPC Agreement.
The decision is particularly relevant for the study of:

• EU patent law and the Unified Patent Court system

• Procedural rights of parties in cross‑border infringement actions

• The interaction between patent exhaustion and market access

• Comparative analysis of national versus unitary patent enforcement

• The role of discretion in EU procedural instruments

Comparing DivX v Netflix with Huawei Technologies v ZTE (CJEU 2020) and Samsung Electronics v Apple (UPC 2022) shows how courts navigate patent exhaustion and validity standards across the EU internal market, highlighting the evolving balance between enforcement efficiency and defendant protections.

For Businesses

• A clause in product‑release checklists can trigger immediate suspension of any feature potentially covered by a UPC‑validated patent across all participating states.

• Standard‑terms agreements that include a rapid‑compliance provision for UPC injunctions specify notice periods and remediation steps.

• Incorporating potential cross‑border injunction exposure into risk‑adjusted cash‑flow forecasts and reserve calculations reflects the financial impact on multinational media groups.

• Updating internal monitoring systems to flag software updates that could fall within the scope of UPC‑covered patents enables swift remedial action.

Key Takeaways

• The UPC can now grant pan‑EU injunctions without a mandatory security requirement, confirming that Article 31 provides only discretionary discretion.

• Patent litigators now factor the possibility of immediate, multi‑state bans into client counseling, budgeting, and settlement strategies.

• Courts and enforcement authorities can enforce EU‑wide injunctions swiftly, without awaiting a separate security order, which tightens the enforcement timeline.
