ITC Section 337
Notable Representations, Key Contacts
“A Section 337 investigation is not mere litigation among private parties.”
Certain Gel-Filled Wrist Rests and Products Containing Same, Inv. No. 337-TA-456, Order No. 10
The ITC is a trade court empowered to investigate and remedy many kinds of unfair acts and competition in the importation of articles into the U.S. The ITC’s combination of unique rules, extreme speed, and powerful remedies makes it an attractive venue for prospective complainants looking to quickly exclude unfair actors from the U.S. market. For respondents, this same combination of factors means that hiring knowledgeable, experienced ITC counsel is critical to countering a complainant’s inherent initial advantage in this unforgiving forum.
Why Section 337
The ITC is a federal agency with broad authority to investigate and remedy unfair acts and competition in the importation of articles into the US. If a violation of the statute is found, the ITC can issue powerful, enterprise-threatening remedies: an exclusion order that blocks product from being imported into the US and a cease and desist order that prevents the further sale or distribution of product already into the US, such as articles stored in a warehouse.
Compared to state or Federal court, section 337 investigations move very quickly. Litigants can expect the Commission’s final determination in around 17 months, with broad yet expedited fact and expert discovery over the course of six to seven months and a five-day evidentiary hearing at around nine months. By way of comparison, an equivalent district court case can take years just to get to trial.
And Section 337 is not just about patents. The ITC can institute an investigation based on a wide range of alleged “unfair acts,” including trade secret misappropriation, trademark and trade dress infringement, false advertising, and other unfair competition tied to imported products. Importantly, even unfair acts occurring exclusively abroad, such as the foreign misappropriation of trade secrets, can support a complaint when the act is tied to in an importation into the US.
