Section 337 Investigations
Comprehensive representation from pre-filing analysis through discovery, the evidentiary hearing, Commission review, remedy proceedings, and appeal — for complainants and respondents alike.
International Trade
Counsel on antidumping, countervailing duty, five-year sunset reviews, Section 201 safeguard actions, and other trade remedy proceedings before the Commission.
“Section 337 is a distinctive area of international trade and intellectual property law — its procedures, remedies, and strategic considerations differ significantly from conventional federal-court litigation.”
For a complainant, the objective may be to stop infringing imported products from entering the United States and protect an important U.S. market. For a respondent, the objective may be equally consequential: preserving access to the U.S. market and protecting a critical product line or supply chain. In either circumstance, decisions made at the outset of an investigation can influence the course of the entire proceeding.
Adduci LLP's Section 337 practice is grounded in decades of experience before the United States International Trade Commission — understanding Section 337 not simply as a form of patent litigation, but as a specialized international trade remedy with its own procedures, jurisprudence, institutional history, and strategic demands.
