Litigation and Antitrust


Joseph Ostoyich is co-chair of the firm’s Litigation Department in Washington, D.C. He has more than two decades of experience representing some of the world’s leading companies in price fixing, monopolization and the full gamut of antitrust litigation in U.S. courts and in investigations and merger reviews by the Department of Justice, the Federal Trade Commission, the European Commission and government authorities around the world. He has represented clients in bet-the-company competitor and class action lawsuits, including more than a dozen different class action clusters in the paper, chemical, foundry, energy, transportation and agricultural commodities industries.

Mr. Ostoyich recently obtained a defense verdict as lead trial counsel in an eight week bench trial against the Federal Trade Commission on charges that his client conspired to fix prices directly and through an industry association. The Commission’s decision to dismiss six of its own counts marked the first time in two decades that the Commission ruled against its own claims. This win earned Mr. Ostoyich and the trial team recognition as “Legal Lions” in Law360’s Weekly Verdict: Legal Lions & Lambs (February 14, 2014).

Additional recent litigation wins include obtaining a zero dollar judgment on behalf of a client facing a multibillion dollar monopolization suit brought by its main rival and winning summary judgment in a price fixing case charging his client with participating in a decade-long conspiracy to fix natural gas prices. In both cases, his cross examination of the opposing experts led the courts to exclude their testimony.

Mr. Ostoyich is recognized as a leading antitrust lawyer in Chambers USA, rated “Preeminent” by Martindale-Hubbell, and has been named a D.C. Super Lawyer for Antitrust. The Legal 500 stated that Mr. Ostoyich “provides clients with a considerable pedigree in relation to a range of federal and state private antitrust litigation.”

He is a member of the Antitrust Council of the U.S. Chamber of Commerce and frequently speaks at industry conferences and client retreats about antitrust law developments. He has written and edited several dozen articles and analyses of the antitrust laws and, most recently, co-authored a chapter on the law and economics of antitrust damages in a leading treatise.

Representative Engagements

  • City of Moundridge, KS v. Exxon Mobil Corporation. As lead counsel for ExxonMobil, Mr. Ostoyich won summary judgment in a case charging the company and several competitors with conspiring to fix the price of natural gas. The district court found the testimony of plaintiffs’ expert to be entitled to “no weight” because it was “wholly unsupported and speculative” and the D.C. Circuit affirmed.
  • ZF Meritor LLC and Meritor Transmission v. Eaton Corporation. Represented Eaton and obtained a final judgment of zero dollar damages and an order excluding the opposing damages expert as “insufficient and unreliable” in a monopolization case claiming several billion dollars in damages.
