Louis Mastriani, a former senior investigative attorney in the U.S. International Trade Commission (ITC) Office of Legal Services (currently known as the Office of Unfair Import Investigations), counsels and assists clients in domestic and worldwide licensing and enforcement programs for intellectual property rights, with an emphasis on high-technology patent portfolios. For more than 40 years, Lou has been involved in unfair competition investigations before the ITC under Section 337, and intellectual property litigation in federal district courts. He also has represented clients in numerous antidumping and countervailing duty investigations at the ITC and the U.S. Department of Commerce, and cases before the U.S. Court of International Trade and the U.S. Court of Appeals for the Federal Circuit. He has also been involved over the years in interacting on behalf of domestic and foreign clients with U.S. Customs in matters involving the administration and enforcement of ITC exclusion orders, protection of intellectual property rights, as well as valuation and classification matters, including appeals to the U.S. Court of International Trade and the U.S. Court of Appeals for the Federal Circuit. Lou also counsels domestic and international clients with respect to compliance with export controls and sanctions protocols, as well as representing them in connection with investigatory and enforcement proceedings. Prior to entering private practice, he served as legal counsel to an ITC Commissioner before becoming a senior investigative attorney in the Office of Legal Services (currently known as the Office of Unfair Import Investigations). As a senior ITC investigative attorney, Lou assisted in revising and drafting the Commission's Rules of Practice and Procedure with respect to Section 337 investigations. While at the ITC, he also litigated numerous Section 337 investigations on behalf of the public interest involving patent, non-patent, and antitrust issues, including self-initiated section 603 investigations. The U.S. Trade Representative appointed Lou as both a panelist and a chairman on bi-national panels convened pursuant to the North American Free Trade Agreement to provide review of antidumping and countervailing duty decisions. Lou has lectured extensively and published articles on international trade issues and intellectual property protections.
