FTC Favorably Cites Brattle Economist’s Testimony in FTC v. Polypore

Dr. John Simpson, a senior consultant in Brattle’s Washington, DC office, was cited in the Federal Trade Commission’s (FTC) opinion in the matter of Polypore International, Inc. (Polypore). This ruling stems from a 2008 FTC complaint alleging anticompetitive practices on the part of Polypore in its acquisition of Microporous Products L.P., a rival battery separator manufacturer. Dr. Simpson, a former FTC economist, served as the expert witness for the FTC. Key issues in the case included the definition of the product market and the analysis of post-acquisition competitive effects. On both of these issues, the FTC favorably cited Dr. Simpson’s testimony. The FTC unanimously found the Polypore transaction to be anticompetitive, ordering the company to be divested within six months to a buyer approved by the FTC. For more information, please see
