Barred at the Border: What a Section 337 Case at the ITC Means for Your Business

If you sell imported products in the United States, a single filing at a federal agency in Washington can put your entire import business at risk. That filing is a Section 337 complaint asking the U.S. International Trade Commission to block your products at the border. The stakes are high, the schedule is fast, and the rules are unlike ordinary court litigation.

This article explains what a Section 337 investigation is, what the ITC can do to your business, and why respondents need experienced trial counsel quickly.

What is a Section 337 case?

Section 337 is a federal statute, codified at 19 U.S.C. § 1337. It makes it unlawful to import products into the United States that infringe a valid and enforceable U.S. patent. The same law also covers other unfair practices in import trade, including infringement of registered trademarks, copyrights, and mask works, and misappropriation of trade secrets.

The U.S. International Trade Commission (USITC, or ITC) enforces Section 337. The ITC is an independent, quasi-judicial federal agency in Washington, D.C., that conducts trial-type proceedings rather than operating as a regular court.

A Section 337 case begins when a company (the “complainant”) files a complaint under oath. It accuses one or more “respondents” (often a foreign manufacturer, a U.S. importer, or a downstream distributor) of importing infringing products. The ITC decides whether to institute an investigation. Once instituted, the case is assigned to an Administrative Law Judge (ALJ).

Patent owners like Section 337 because it targets the border. If the accused products come from overseas, the ITC can order U.S. Customs to keep them out.

What can the ITC actually do to my business?

This is the part that makes Section 337 powerful. The ITC cannot award money damages. It offers a different remedy, and for many businesses a more painful one.

The primary remedy is an exclusion order. An exclusion order directs U.S. Customs and Border Protection to stop the infringing products from entering the country. A “limited” exclusion order applies to the named respondents’ products. A “general” exclusion order can, in certain circumstances, bar the products no matter who imports them.

The ITC can also issue a cease-and-desist order. That order bars a respondent from selling off inventory already inside the United States, and from marketing, distributing, or otherwise dealing in the infringing goods here.

Violating a cease-and-desist order carries civil penalties of up to $100,000 per day, or twice the value of the imported articles, whichever is greater.

Because the remedy is a border block rather than a monetary award, a Section 337 case can shut down a product line even where the potential damages in court would be modest. That leverage is exactly why complainants choose the ITC.

At Harness IP, we have successfully guided clients through the ITC process for precisely this reason. Consider an overseas manufacturer, for example, where obtaining service of process in a district-court action or collecting any damages may prove difficult. The ITC provides a comparatively rapid, injunction-style remedy that can stop the imports at the border even when monetary recovery is unlikely.

How fast does it move?

Section 337 is built for speed. Within 45 days after an investigation is instituted, the ALJ sets a “target date” for the ITC’s final determination. Target dates are commonly set at roughly 16 to 18 months from institution, though they vary by case.

Discovery opens almost immediately and moves quickly. Depositions, document production, and expert reports are compressed into months, not years. There is an evidentiary hearing (essentially a trial) before the ALJ.

After the hearing, the ALJ issues an initial determination on whether Section 337 has been violated. Under ITC practice, the initial determination is generally issued about four months before the target date.

The initial determination is not the last word. A party may petition the Commission to review it, generally within 12 days of service. The Commission (the ITC’s presidentially appointed commissioners) can review and adopt, modify, or reverse the ALJ’s decision. If the Commission declines to review, the initial determination becomes the Commission’s final determination.

What is the Presidential review period?

Even after the Commission finds a violation and issues remedial orders, one more step remains. ITC orders are effective when issued, but they become final only after a 60-day Presidential review period.

During those 60 days, the orders can be disapproved for policy reasons. That authority has been delegated to the U.S. Trade Representative. Disapproval is rare, but the window exists. If the orders are not disapproved within 60 days, they take full effect and infringing imports are barred.

A respondent who loses at the ITC can appeal the Commission’s final determination to the U.S. Court of Appeals for the Federal Circuit.

What is the “domestic industry” requirement?

A complainant cannot use Section 337 unless it protects a genuine U.S. industry. This is the “domestic industry” requirement, and it is often the strongest defense a respondent has.

The statute has two parts. The complainant must show a domestic industry “exists or is in the process of being established” relating to the articles protected by the patent. Under 19 U.S.C. § 1337(a)(3), that industry is shown by activity in the United States tied to the patented technology, through one or more of:

• significant investment in plant and equipment;
• significant employment of labor or capital; or
• substantial investment in the patent’s exploitation, including engineering, research and development, or licensing.

That is the “economic prong.” There is also a “technical prong”: the complainant must show its own products (or its licensees’ products) actually practice the asserted patent. A complainant whose U.S. presence is thin, or whose products do not practice the patent, may fail this requirement — and the whole case can turn on it.

How is an ITC case different from a district-court lawsuit?

A Section 337 case and a patent lawsuit in federal district court can involve the same patent and the same parties, yet they are not the same proceeding. Key differences:

• Remedy. The ITC issues exclusion and cease-and-desist orders. It does not award money damages. A district court can award damages but takes longer.
• Speed. The ITC runs on a fixed target date, usually well under two years. District-court patent cases often take longer.
• Domestic industry. A district-court plaintiff need not prove a domestic industry. An ITC complainant must.
• Reach. The ITC’s orders act at the border and reach imported goods directly. District-court injunctions against foreign sellers can be harder to enforce.

The two often run in parallel. A patent owner may file at the ITC and in district court at the same time. A respondent can ask the district court to stay its case while the ITC proceeds. Positions taken in one forum can affect the other, so the two cases must be managed as one coordinated strategy.

Why do I need to act fast, and with experienced trial counsel?

The ITC’s compressed schedule punishes delay. Discovery and expert work begin almost immediately, and there is little room to get organized after the fact. Decisions made in the first weeks — on claim construction positions, prior art, domestic-industry challenges, and public-interest arguments — shape the outcome.

Many Section 337 respondents are non-U.S. companies. A foreign manufacturer sued in the United States, whether at the ITC or in district court, needs U.S. trial counsel who can litigate the case here and coordinate across both forums.

If your company has been named in a Section 337 complaint, or believes one is coming, the time to build the defense is now.
