Sean M. Tepe


Sean M. Tepe practices in the area of civil and criminal antitrust litigation and investigation and counsels clients on antitrust issues generally and on issues at the intersection of antitrust and intellectual property in particular.

Mr. Tepe has represented clients in a variety of industries, including automotive, chemical, mining, pharmaceutical, securities, technology and transportation, in litigation or before government agencies.

Notable representations include:

  • Norfolk Southern Railway Co., in a multi-defendant price-fixing class action litigation;
  • China Minmetals Corp., a Chinese state-owned metals and minerals corporation, in a class action litigation that has implicated the extraterritorial application of the U.S. antitrust laws;
  • Amylin Pharmaceuticals, Inc., in bringing a claim against a former business partner alleging efforts to allocate a market for pharmaceuticals;
  • Actavis, Inc., in class action suits challenging so-called “reverse payment” settlements of patent infringement litigation; and
  • leading industrial companies in criminal investigations before federal and state grand juries for alleged bid-rigging and price-fixing.

In addition, Mr. Tepe advises clients on issues concerning patent and technology licensing and on developments in antitrust law that impact sectors of the economy where intellectual property rights play a leading role. He has authored articles commenting on such developments, including articles nominated for the Institute of Competition Law’s 2014 Antitrust Writing Awards. One of those articles, “Thoughts on Google’s FTC Settlement,” won Best Business Dominance Article and was co-authored with Alec Y. Chang, Matthew P. Hendrickson, Sharis A. Pozen and Steven C. Sunshine.

Mr. Tepe has devoted time to pro bono work in support of the rights of workers. He has supported the labor trafficking claims of welders and pipefitters who were fraudulently recruited from India to Gulf Coast shipyards after Hurricane Katrina and forced into guarded, squalid labor camps. He also has represented Chinese restaurant workers seeking to recover wrongfully withheld overtime pay and gratuities.
