Bateman is a partner in the Washington D.C. office of Kenyon & Kenyon, LLP. He has had experience in a wide variety of intellectual property litigation matters concerning patents, trademarks, copyrights, and trade secrets, and has practiced before the Court of Appeals for the Federal Circuit, numerous federal district courts, and the U.S. International Trade Commission (ITC).

Mr. Bateman's practice has focused on patent litigation concerning biochemical and computer technology, but he has been involved with matters related to a wide range of products, including pertussis vaccines, birth control pills, potassium supplements, coronary stents, drapery hooks, eyeglass lenses, gasoline pumps, and electrical connectors. He has litigated many different types of cases, with a particular emphasis on actions brought under the Hatch-Waxman Act. In addition, he has extensive knowledge regarding section 337 investigations at the ITC.

Cases in which Mr. Bateman has worked include Texas Instruments, Inc. v. United States Int'l Trade Comm’n, 988 F.2d 1165 (Fed. Cir. 1993), in which the Federal Circuit affirmed the ITC's decision that four American semiconductor companies could continue to import integrated circuits that TI had alleged infringed its patent; and Calmar, Inc. v. Emson Research, Inc., 850 F. Supp. 861 (C.D.Cal. 1994), in which the Court found that the patent owner had failed to properly mark its product, thereby minimizing any possible damages which Kenyon's client, Emson, would even possibly have to pay.
