King & Spalding attorneys have been involved in some of the largest, most complex and precedent setting Section 337 cases ever litigated at the U.S. International Trade Commission. Unique among firms, King & Spalding has specialized expertise in the disciplines necessary to litigate Section 337 investigations at the ITC:  broad-based patent litigation experience and technical expertise, extensive hearing experience at the ITC, expertise in international trade and the ITC’s  procedures, intellectual property appellate expertise, and  top-tier governmental relations expertise. We have represented clients in bet-the company litigation; one of our recent Section 337 investigations was described as one of the largest patent cases ever brought.

Our Section 337 Expertise

Our Section 337 patent litigation team combines significant litigation expertise with a strong technical background. Our attorneys have conducted numerous hearings at the ITC over the last 10 years. We also have tried more than 100 cases to judgment in the district courts, argued over 100 appellate cases, including before the U.S. Supreme Court, had more than 200 cases decided on summary judgment, conducted more than 60 Markman hearings and had over 500 cases settled favorably prior to trial. We are particularly deep in electrical, computer, and mechanical patent expertise, which comprise the majority of investigations at the ITC under Section 337. Our professionals include engineers, scientists and programmers with decades of industry experience across diverse industries and specialties, including more than 20 Ph.D.s, in a wide range of disciplines. Our Section 337 patent lawyers have been nationally recognized by Chambers, Managing IP Magazine, Best Lawyers in America, SuperLawyers, and IAM 1000, among others.  Our ranks include a Past President of the ITC Trial Lawyers Association, recommended by IAM 1000 “The World’s Leading Patent Practitioners” as a leading ITC Section 337 practitioner, and current Executive Committee member and officer of the ITC Trial Lawyers’ Association.

Our Section 337 international trade lawyers bring unique skills and perspectives to the domestic industry, remedy, importation, public interest, enforcement, international trade, and procedural aspects of Section 337 investigations. The group includes a roster of former government officials, including many former ITC officials. In addition, a former King & Spalding lawyer is currently a Commissioner on the ITC. Our international trade lawyers also have been active in Section 337 legislative initiatives, including crafting amendments to Section 337 in the Omnibus Trade and Competitiveness Act of 1988 and assisting Congress in 1994 to amend Section 337 so as to bring it into compliance with the GATT’s requirement of “national treatment.”

Our Government Relations lawyers have the experience and expertise to manage the government relations aspects of Section 337 investigations and to assist clients with relevant legislative initiatives. These include the public interest and presidential review aspects of Section 337 investigations.

Finally, our D.C.-based national appellate practice group specializes in intellectual property appeals before the U.S. Court of Appeals for the Federal Circuit, which hears Section 337 appeals. The head of our appellate practice, a former Principal Deputy in the Office of the Solicitor General, has been recognized by Chambers USA and is “highly  recommended” by Benchmark for handling Federal Circuit appeals.
