The International Trade Commission (ITC) is an increasingly popular venue for intellectual property rights enforcement. Under 19 U.S.C. § 1337 (Section 337), the ITC conducts investigations and provides relief for intellectual property rights holders by barring the importation or sale after importation of goods that infringe upon a utility patent, design patent, trademark, or copyright, or goods that are made using misappropriated trade secrets.

Section 337 authorizes the ITC to investigate a wide variety of unfair methods of competition and unfair acts in the importation of goods. At the conclusion of a Section 337 Investigation, the ITC can issue an exclusion order barring goods from being imported into the United States, and barring the sale of existing inventories of imported goods in the United States, requiring their destruction or removal from the country. 

An exclusion order is a unique and powerful remedy that poses a daunting problem for foreign manufacturers, who risk losing access to the U.S. market, and for domestic importers and sellers, who risk a disruption of their supply of goods found to infringe. Moreover, the ITC can issue a general exclusion order barring all products from any source. As such, Section 337 Investigations are often “bet-the-company” litigations for respondents. 

Section 337 Investigations are fast paced, with evidentiary hearings (trials) often occurring less than one year after an investigation is instituted, as detailed in our exemplary timeline of a Section 337 Investigation. Developments in patent law over the last several years have made litigation in U.S. district court less attractive for patent owners, and have caused a renewed interest in the ITC as the venue of choice in the United States for asserting IP rights.

The exclusion order remedy is enforced by U.S. Customs and Border and Protection (CBP) at U.S. ports of entry. Violations of an exclusion order are addressed before the ITC in enforcement proceedings. Requests to import goods that design-around the intellectual property in an exclusion order are addressed by the CBP under 19 C.F.R. § 177 (often referred to as Rule 177 proceedings) or the ITC in an advisory opinion proceeding.

Practical Representation Focused on Client Business Objectives

Intellectual property rights holders considering relief under Section 337, and companies accused of violating Section 337, need knowledgeable counsel to navigate the complex issues, short time frames and high stakes associated with these investigations. Our team of veteran litigators work to achieve our clients’ business objectives in a cost-effective manner.




    Successfully defended a client in the first-ever “100-day” hearing initiated under the ITC’s new pilot program designed to resolve patent infringement allegations within 100 days. The ITC determined that there was insufficient economic investments in the United States relating to the asserted patents to establish a domestic industry and terminated the investigation.


    We obtained the first-ever delay of an ITC exclusion order for our client based on public interest considerations in a decision, Inv. No. 337-710, that is routinely cited by others seeking similar relief. With the extra time, we were able to obtain approval for our client to import a “design around” alternative without disrupting its supply chain.
