Benjamin D. Brown is a Partner at Cohen Milstein, and Co-Chair of the firm's Antitrust practice group. Mr. Brown is also a member of the firm’s Executive Committee.

Mr. Brown, who previously served in the Antitrust Division of the United States Department of Justice, brings to his role extensive experience leading complex litigation, particularly antitrust class actions.

Mr. Brown has been appointed by federal courts to serve as co-lead counsel for plaintiffs in numerous important matters, such as In re Plasma-Derivative Protein Therapies Antitrust Litigation (N.D. Ill.); Carlin, et al. v. DairyAmerica, Inc. (E.D. Cal.); and Mixed Martial Arts (MMA) Antitrust Litigation (D. Nev.). He has led cases through trial and argued appeals and stands ready to take cases through to the finish line.

Mr. Brown is also an adjunct professor at Georgetown Law School, where he teaches Complex Litigation, a course that explores the policy and procedures implicated by aggregated, high stakes, multi-party litigation, especially class actions.

Mr. Brown is also a leader in the area of takings cases, claims that are brought under the Fifth Amendment of the U.S. Constitution for the unconstitutional taking of property without compensation. He also represents individuals or groups in litigations and confidential arbitrations involving complex commercial disputes, particularly those involving regulated markets. 

Currently, Mr. Brown is litigating a number of large, complex antitrust and price manipulation lawsuits, where he plays a prominent role and leads all aspects of the litigation, from deciding on the claims to be brought, the strategy to be pursued and charting the course of the case. Notable matters include:

  • Mixed Martial Arts (MMA) Antitrust Litigation (D. Nev.): Cohen Milstein is co-lead counsel in a class action on behalf of MMA fighters alleging that Zuffa LLC – commonly known as the Ultimate Fighting Championship or “UFC” – has unlawfully monopolized the markets for promoting live professional MMA bouts and for purchasing the services of professional MMA fighters.  The district court denied the defendant’s motion to dismiss the case in September 2015 and discovery is ongoing.  Mr. Brown is co-lead in this class action.
  • Allen, et al. v. Dairy Farmers of America, Inc. (D. Vt.): Cohen Milstein served co-lead counsel in a class action lawsuit on behalf of Northeast dairy farmers against Dairy Farmers of America (DFA) and Dean Foods Company charging a conspiracy to reduce competition for raw milk and that DFA monopolized the milk market in the Northeast, forcing dairy farmers to market their milk through DFA or its affiliate Dairy Marketing Services (DMS). Final, approved settlements total $80 million.
  • DairyAmerica Litigation (E.D. Cal.): Cohen Milstein served as court-appointed lead counsel to a putative class of dairy farmers who alleged that defendants fraudulently misreported nonfat dry milk prices to the National Agricultural Statistics Service, resulting in artificially depressed raw milk prices and unfairly depriving American dairy farmers of tens-of-millions-of-dollars. In May 2019, the Court granted final approval of a $40 million settlement – 90% of the USDA Inspector General’s independent analysis estimated damages. Mr. Brown directed all aspect of this class action.

Mr. Brown is also currently litigating a number of takings lawsuits, including the following notable matters:

  • Ideker Farms, et al. v. United States of America (Fed. Cl.): Cohen Milstein represents Ideker Farms and more than 400 other plaintiffs located in six states along the Missouri River in a landmark mass action lawsuit in the U.S. Court of Federal Claims alleging that the federal government took land and flooding easements over lands owned by farmers without any compensation in violation of the takings clause of the Fifth Amendment. Mr. Brown has helped lead the litigation team, including during a months-long liability trial in 2017, during which he directed and cross-examined numerous witnesses, including six experts.  In March 2018, the Court ruled largely in favor of plaintiffs on liability and cause of flooding claims. Bellwether trials continue. The Court will next determine the extent of the losses due to the taking.
  • Big Oak Farms, Inc., et al. v. United States of America (Fed. Cl.): Cohen Milstein represents over 100 farmers along the Mississippi River in a Fifth Amendment takings case alleging that the U.S. Army Corps of Engineers intentionally flooded plaintiffs’ land without providing just compensation. Mr. Brown has been directing and leading all aspects of the litigation.
