IP Licensing Dispute With a China Counterparty: Enforcement Options

If a Chinese licensee has stopped paying royalties, underreported sales, or sublicensed your patent without permission, you have four realistic paths and none of them is a quick win. An IP licensing dispute with a China counterparty turns on enforcement, not on who is right. You can pursue a USITC border remedy, chase recognition of a US judgment inside China, use Hong Kong mediation under its new neutral-forum reforms, or negotiate a paid exit. Which one fits depends on where the infringer’s goods and money actually sit.

Start there. Filing a US lawsuit on reflex, then assuming the judgment collects itself, is the wrong first move.

Read the Contract Behind an IP Licensing Dispute With a China Counterparty

Before you weigh any remedy, pull the licensing agreement and find three clauses. The governing law clause tells you whose law applies. The dispute-resolution clause tells you whether you agreed to arbitration or to a named court. The audit clause tells you whether you can inspect the licensee’s books to prove underreporting.

That audit right is the quiet hero of royalty disputes. Underreporting is common. It is also hard to catch from the outside, because the only numbers you ever see are the numbers the licensee chose to send you. If your contract lets you put an independent auditor on the books on notice, use it before you escalate anything.

One structural fact changes everything downstream. If your clause sends disputes to arbitration, you are in far stronger shape than if it sends them to a US court. China has been a contracting state to the 1958 New York Convention since 1987, so a foreign arbitral award is generally recognized and enforced by Chinese courts. A US court judgment carries no such treaty. We cover the trade-offs in arbitrator impartiality in IP licensing deals and in alternative dispute resolution for small business owners.

USITC Section 337: The Border Remedy With Teeth

If the counterparty ships infringing products into the United States, the US International Trade Commission is often the sharpest tool a small business has. Section 337 investigations target unfair imports. The remedy is an exclusion order that directs Customs to stop the goods at the border. It does not award you money. It cuts off the US market, which is usually the leverage that ends the dispute.

The timeline is unusually fast for IP. The Commission sets a target date within 45 days of instituting an investigation, and cases typically conclude in roughly 16 months, per the Congressional Research Service overview of Section 337. A remedial order takes effect on issuance and becomes final 60 days later, subject to a policy review by the US Trade Representative, according to the USITC’s own Section 337 materials.

There is a catch that trips up licensors. You must prove a domestic industry: both articles that practice the IP and significant US investment tied to them. A licensing program can satisfy the economic side, but only if you can point to licensed articles that actually practice the patent. The Federal Circuit tightened this across 2024 and 2025, requiring a complainant to allocate investment to each asserted patent rather than lump it together, as Greenberg Traurig explains. Speed carries a price. The compressed schedule front-loads discovery and expert work, so fees run steep.

Getting a US Judgment Recognized in China

Suppose you win in a US court. Collecting inside China used to be close to hopeless. That shifted. In October 2024, the Wuxi Intermediate People’s Court enforced a California judgment worth about $73 million, the first time a Chinese court enforced a US money judgment on the basis of reciprocity, as documented in East IP’s case analysis. The underlying California award traced back to litigation over breach of contract and fraud, finalized on appeal in 2019, and it still took a separate Chinese recognition proceeding years afterward to turn that paper into an enforceable order.

The framework behind that ruling matters more than the headline. China’s Civil Procedure Law, amended in 2023, lets a court recognize a foreign judgment under a bilateral treaty or the principle of reciprocity, and Chinese courts have moved toward presumptive, or “de jure,” reciprocity, per DLA Piper. No US-China treaty exists. Reciprocity is the whole game.

Be candid about what this means for a small plaintiff. You first win a US judgment. Then you bring a separate recognition proceeding in a Chinese court, where public-policy exceptions and judicial discretion still apply and the calendar keeps its own pace. Finality is not optional. A Chinese court has already dismissed an application to enforce a US judgment that was still open to appeal, per China Justice Observer, so the order you carry across the Pacific has to be genuinely final before it is translated and authenticated for a court in Wuxi or Shanghai. That is a two-front effort measured in years. It is worth the spend only when the counterparty holds real assets in mainland China and your US case is already strong.

Hong Kong Mediation and the Neutral-Forum Reforms

Border orders and judgment fights are adversarial and slow. For many royalty disputes, a facilitated settlement is the faster route to actual cash, and Hong Kong has spent two years positioning itself as the neutral seat for US-China commercial matters. In May 2025, it became home to the International Organization for Mediation, the first intergovernmental body built to mediate international disputes, per the Brookings Institution. On May 28, 2026, the Hong Kong Judiciary announced a new International Commercial Court for complex cross-border cases, per Morrison Foerster.

Know one enforcement gap before you count on a mediated deal. The Singapore Convention on Mediation would make cross-border mediated settlements directly enforceable. Both the US and China signed it in 2019. Neither has ratified it, and only a small group of states has, per the UNCITRAL status record. So a Hong Kong mediated settlement is powerful, but its teeth still come from the contract you sign. Structure the deal so a breach converts into an arbitral award, which the New York Convention will carry into China. Our guide to preparing for IP licensing mediation covers how to walk in ready.

The Negotiated Exit Is Often the Realistic Winner

For a small business, a negotiated exit usually beats a courtroom victory on a spreadsheet. Every remedy above is leverage. A documented audit shortfall and a credible threat of losing US market access both push a rational counterparty toward paying. Trade that leverage for something you can bank now, whether a lump-sum catch-up on unpaid royalties or a license buyout with a real audit clause bolted onto whatever relationship survives. A signed settlement backed by an arbitration clause is worth more than a default judgment you cannot collect.

What to Do This Month

The order of operations matters more than the size of your claim. Move deliberately and keep the paper clean.

• Exercise your audit right and get independent numbers on the underpayment before you threaten anything.
• Map the counterparty’s footprint: goods entering the US point to Section 337, assets in China point to judgment recognition, an ongoing relationship points to mediation.
• Read the dispute clause to confirm whether you are headed to arbitration or court, because that decides how enforceable any win will be.
• Send a specific demand tied to the audit figure, with a short deadline and one clear ask.

Cross-border IP enforcement rewards preparation over speed. If you are staring at an unpaid royalty statement and a counterparty on the other side of the Pacific, a short consultation to map your leverage and pick one path costs far less than pursuing all four at once.
