Michael Mayer

Practice Areas

Michael is a trial lawyer who represents companies and individuals in antitrust and complex commercial litigation matters in federal and state courts around the country. He has broad experience in class action defense, intellectual property matters, grand jury proceedings, and responding to government investigation claims of anticompetitive practices and consumer fraud. Michael is also an adjunct professor at Northwestern Pritzker School of Law where he teaches a course regarding pretrial strategies.

As a Chambers USA ranked antitrust attorney, Michael Mayer has secured victories for his clients in some of the largest and most significant antitrust disputes in the country, many involving class actions and white-collar criminal matters and investigations. In his commercial trial practice, he represented a beef producer in the US$6 billion “pink slime” litigation against ABC. The case has been called the largest defamation case in U.S. history, and it was resolved favorably after four weeks of trial. In addition to his antitrust and commercial litigation practice, Michael also specializes in partnership and trusts and estates disputes, particularly those involving the allocation of family business assets and partnership breakups. He has litigated estate and family disputes for over 20 years both for the estate and on the opposite side—when a family member challenges a will or trust and makes fraud claims directed towards the estate’s assets.

Michael has been recognized by several prominent publications for his antitrust and complex litigation work including Chambers USA, The Legal 500 US, Benchmark Litigation US, and Lawdragon.
