Drawn by a fast forum and an effective remedy, companies and their intellectual property lawyers are filing a record number of cases this year at the U.S. International Trade Commission as they seek to block patent-infringing products from entering the United States.

The commission, a quasi-judicial federal agency with broad investigative powers in trade matters, adjudicates complaints brought by domestic industries under Section 337 of the Tariff Act of 1930 that allege infringement of U.S. intellectual property rights, most often patent and trademark infringement by imported goods.
