ITC Section 337 Investigations
The US International Trade Commission (ITC) is one of the most popular venues for U.S. companies and foreign companies with a U.S. market presence to litigate their intellectual property disputes in what is known as Section 337 investigations. Companies must understand the unique requirements and steps involved in a Section 337 investigation since there are several key differences between these investigations and traditional district court litigation.
Although the ITC cannot award monetary damages, it can issue exclusion orders to prevent infringing products from entering the United States or cease-and-desist orders to stop the sale of infringing products already in the U.S. Litigating in the ITC is an aggressive, high-stakes approach that requires a skillful team with the technical knowledge and trial experience to achieve results for both complainants and respondents.
