China withdraws anti-suit injunction policy following adverse WTO ruling secured by the European Union

Executive Summary

The European Commission's Directorate-General for Trade published a release on 1 April 2026 confirming that China has announced withdrawal of its anti-suit injunction policy following a WTO ruling finding that policy in violation of WTO rules. The development resolves a longstanding bilateral trade dispute with direct implications for standard-essential patent litigation strategy, cross-border IP enforcement, and the jurisdictional posture of EU-based rights holders operating in Chinese courts.

Key Regulatory Signals

• Anti-Suit Injunction Exposure Eliminated: Chinese courts' practice of issuing anti-suit injunctions to block foreign litigation over standard-essential patent licensing disputes is formally withdrawn, removing a primary litigation risk for EU-domiciled patent holders and licensors with active or prospective proceedings in non-Chinese jurisdictions.
• SEP Licensing and FRAND Negotiations Rebalanced: Parties engaged in standard-essential patent licensing negotiations with Chinese counterparties should reassess their litigation leverage and forum strategy, as the coercive threat of Chinese anti-suit injunctions blocking EU or UK court proceedings is no longer operative under the announced policy change.
• WTO Dispute Settlement Mechanism Validated: The ruling and China's compliance response confirm that WTO adjudication remains a functional enforcement channel for IP-adjacent trade disputes, relevant to legal and regulatory strategy teams monitoring multilateral enforcement options.
• Cross-Border IP Enforcement Posture Requires Review: Compliance and legal teams managing international IP portfolios should audit existing litigation holds, forum selection clauses, and licensing agreements structured in anticipation of Chinese anti-suit injunction risk, as the underlying threat architecture has materially changed.
• Reciprocal Regulatory Monitoring Warranted: The EU's successful WTO challenge may prompt reassessment of analogous trade instrument disputes; affected parties should monitor whether China pursues compensatory or retaliatory trade policy adjustments in adjacent sectors.

Regulatory Delta

The EU-China anti-suit injunction dispute originates from a pattern of Chinese court orders, most prominently from the Wuhan Intermediate People's Court beginning in 2020, which blocked foreign courts from adjudicating FRAND licensing rate disputes involving Chinese implementers of standard-essential patents. The current item represents a structural resolution rather than incremental escalation, as China's announced withdrawal of the policy in response to a binding WTO ruling constitutes a compliance act under the multilateral dispute settlement framework rather than a unilateral concession or bilateral negotiated outcome. This outcome aligns with the EU's broader Digital Decade and Single Market IP enforcement agenda, and follows the EU's 2023 SEP Regulation proposal. The confirmation that WTO dispute settlement produced a binding and complied-with outcome in an IP-trade intersection case is itself a precedent of note, as prior enforcement actions in this domain had not produced equivalent formal withdrawal commitments from China.

Materiality Classification

High — China's withdrawal of anti-suit injunction policy following a binding WTO ruling materially alters SEP licensing leverage and cross-border IP enforcement strategy for EU-domiciled patent holders engaged with Chinese counterparties.

Time Horizon

Immediate — China's announced policy withdrawal takes effect now; SEP licensors and licensees with active or pending Chinese court proceedings must immediately reassess forum strategy and litigation holds.

Intelligence Outlook

Monitor DG Trade and WTO dispute panels for follow-on proceedings as the EU evaluates further IP trade enforcement actions against China. Watch for Chinese legislative or regulatory responses that may attempt to re-establish functional anti-suit injunction capacity through alternative mechanisms.
