Experience
Kellie Lerner is nationally recognized for her work over the last two decades representing clients in high-stakes antitrust disputes across the country. Ms. Lerner has successfully led numerous antitrust class actions and currently serves in leadership positions in BCBSM, Inc. v. Vyera Pharmaceuticals, LLC, et al., In re Merck Mumps Vaccine Antitrust Litig., In re Hard Disk Drive Suspension Assemblies Antitrust Litig., and Sterk, et al. v. The Bank of Nova Scotia, et al. Ms. Lerner previously represented a publicly traded corporation where she successfully obtained a complete dismissal of a federal and multi-state antitrust class action filed against her client. She has also counseled generic pharmaceutical, alternative energy, and entertainment companies on competition issues. Ms. Lerner is particularly adept at identifying new antitrust actions, initiating the first antitrust class action lawsuits in the country in dozens of actions that have ultimately resulted in billions of dollars in recoveries for victims of anticompetitive conduct.
Chambers USA recognizes Ms. Lerner as one of the country’s top plaintiff’s antitrust attorneys. Ranked Band 1 for the last five consecutive years, Ms. Lerner is described by her peers in Chambers as “an excellent strategist and one of the first colleagues I call to collaborate on a novel issue.” Ms. Lerner is a “zealous advocate,” and “an amazing attorney who mixes vision and skill with respect and team building. She has been a trendsetter in taking on difficult and innovative cases.” Chambers similarly notes that Ms. Lerner has been praised by her peers for her ability to “get large teams of people to work effectively together,” and as “a brilliant tactician and a fierce litigator. She does this while maintaining a cordial relationship both with other plaintiffs’ counsel and with defense counsel.” The Legal 500 USA also praised Ms. Lerner for her “superior intellect, determination and political savvy in getting the job done.”
Ms. Lerner is a two-time recipient of Crain’s New York Business’ “100 Notable Women in Law” award, has been named to Global Competition Review’s prestigious “Women in Antitrust list,” and is the recipient of the New York Law Journal’s “Distinguished Leader” and “New York Trailblazer” awards, as well as the National Law Journal’s "Elite Women of the Plaintiff's Bar" and “Antitrust and M&A Trailblazer” awards. Ms. Lerner was selected by Benchmark Litigation as a “Litigation Star” and is the recipient of Inside Counsel's "National Women in Law" award. A frequent author and lecturer, Ms. Lerner is a recognized voice on all issues of antitrust law and her opinions have been quoted in The Washington Post, Bloomberg Businessweek, Yahoo News, and CBS MoneyWatch, among other publications.
