Mr. Ewing also handles class action and other civil antitrust suits in US courts. His clients appreciate his forward-thinking approach and his ability to translate complex legal and factual situations into concrete choices that help clients make the best possible decisions for their businesses.

He counsels clients about other kinds of business initiatives, such as long-term, exclusive or reciprocal supply or distribution arrangements, responses to industry de-regulation, and antitrust compliance programs. His industry experience includes electronics components, auto parts, plastics and various industrial chemicals, air transportation, food, pharmaceuticals, travel reservation systems, express package delivery services, gas and oil pipelines, electricity, medical equipment, construction equipment, and telecommunications.

Representative Matters

  • Defending Japanese auto parts maker in ongoing DOJ investigation of multinational cartel and in follow-on class action civil damages claims in In re Automotive Parts Antitrust Litigation, (E.D. Mich.) (Steel Tubes).
  • Defending National Milk Producers Federation in ongoing US class action civil damages claims in Matthew Edwards et al. v. National Milk Producers Federation et al., (N.D. Cal.), and First Impressions Salon, Inc. v. National Milk Producers Federation et al., (S.D. Ill.). These cases under state and federal laws involve an unusual theory of joint efforts to raise prices by subsidizing reduced output, as well as application of an antitrust exemption for agricultural cooperatives.
  • Defending MonoSol RX in civil antitrust enforcement actions by 46 states in Wisconsin et al. v. Indivior Inc. et al., (E.D. Pa.). The states allege a novel theory that a supplier conspired with a manufacturer to delay entry of generic pharmaceuticals by providing a new form for the branded pharmaceutical.
  • Defended LG Chem, Ltd. in DOJ and EC investigations and class action civil damages claims in In re Lithium Ion Batteries Antitrust Litigation, (N.D. Cal.).
  • Defended individuals in various DOJ investigations of international cartels, including capacitors, and certain auto parts.
  • Defended FedEx Corp. in civil conspiracy claims in AFMS LLC v. United Parcel Service Co. and FedEx Corp, (C.D. Cal.), helping to secure a complete dismissal before trial despite superficial similarity to binding, unique precedent. The success of this matter was due in large part to our close collaboration with the client’s very strong in-house legal department.
  • Advised major US trade association on various activities to respond to strong political and commercial pressures, including intensive White House scrutiny and price-regulatory initiatives in the US and abroad.
  • Advised various clients in food, apparel, major facilities construction, military equipment, and other sectors on pricing, distribution, and bidding practices.
  • Advised Japanese manufacturer on restructuring long-time business arrangements into multinational joint venture with German industrial machinery manufacturer in highly concentrated global markets.
