The Office of Unfair Import Investigations (OUII) participates as a full party representing the public interest in adjudicatory investigations conducted under section 337 of the Tariff Act of 1930. These investigations most frequently involve allegations of patent or trademark infringement. Allegations of copyright infringement, misappropriation of trade secrets, passing off, false advertising, and antitrust violations also can be litigated in these investigations. In addition to the investigation of a complaint under section 337, the Commission may conduct an enforcement proceeding to determine whether the importation or sale of a specific product violates an existing Commission order. Also, the Commission may issue advisory opinions regarding whether certain anticipated conduct would violate an outstanding Commission order.


The mission of the Office of Unfair Import Investigations is to investigate and assess the sufficiency of complaints filed under section 337 of the Tariff Act of 1930, participate as a party representing the public interest in section 337 investigations, identify relevant issues and develop relevant information in such investigations, and conduct appropriate preliminary investigations under section 603 of the Tariff Act.
