TransWeb, a filtration media supplier, brought a Walker Process fraud claim again 3M, alleging that 3M attempted monopolization by seeking to enforce certain patents against TransWeb. Aside from 3M, TransWeb is the only other supplier of fluorinated filtration media that is used effectively in oil-resistant respirators certified by the National Institute for Occupational Safety and Health, and federally mandated for use certain workplaces. Compass Lexecon expert Brad Reiff testified on behalf of TransWeb regarding the competitive effects of 3M’s actions and damages. On November 26, 2012, a unanimous jury returned a verdict in favor of TransWeb on the attempted monopolization claims, and awarded treble past damages, including attorney’s fees incurred by TransWeb in defense of 3M’s patent claims. Dr. Reiff was supported by Kirupa Ramaiah in our Chicago office. Compass Lexecon worked with Harold Barza, Michael Williams and Adam Wolfson of Quinn Emanuel Urquhart & Sullivan, LLP.
