Insights & News

An accomplished antitrust, sports, and commercial litigator, Jeanifer concentrates her practice on civil antitrust litigation with a particular focus in mixed issues of antitrust and intellectual property law, and class actions. She represents clients in some of the most complex antitrust, sports, and intellectual property disputes in the country at the trial and appellate levels. She has represented clients in high-profile matters such as the landmark Supreme Court decision against the NCAA on behalf of classes of D-I college athletes and Women’s National Soccer Team’s gender discrimination litigation. Jeanifer has been recognized by top ranking publications including Chambers USA, Legal 500 US, SuperLawyers, and Law360. Most recently, she was named in Global Competition Review’s 2024 “40 Under 40” honor roll.

Jeanifer’s practice focuses on all aspects of antitrust/competition, sports law, intellectual property, and complex litigation. She regularly represents major U.S. and multinational corporations in connection with a wide array of federal and state antitrust and competition issues, including monopolization, price fixing, wage fixing, merger enforcement, group boycotts, exclusive dealing, tying, price discrimination, unfair competition, and mixed issues of antitrust and intellectual property law relating to Fair, Reasonable, and Non-Discriminatory (FRAND) obligations, standard-setting, patent licensing, and patent misuse. Jeanifer represents clients across multiple industries, including sports and entertainment, financial services, technology, food and beverage, and retail.

In addition to Jeanifer’s antitrust experience, she has also represented clients facing patent infringement, employment discrimination claims, and consumer fraud and other business tort and breach of contract claims. She also has experience in alternative dispute resolution, including commercial arbitration and mediation.

She has been recognized for obtaining critical wins for her clients whether at trial, on appeal, or by obtaining complete dismissals. Recently, she successfully defended PetIQ in a private merger challenge, where she argued an appeal to the Ninth Circuit and successfully secured a dismissal of the complaint. Jeanifer also has a major role in Winston’s renowned sports practice, successfully trying antitrust claims to a landmark win for college athletes against the NCAA upheld by the Supreme Court, and in a high-stakes, high-profile gender discrimination lawsuit on behalf of the Women’s National Soccer Team in their pursuit of equal pay.

In February 2022, Jeanifer was among the team of lawyers named as runners-up for “Litigator of the Week” by The American Lawyer for their representation of current and former members of the U.S. Women’s National Team in their landmark settlement of the equal pay portion of their lawsuit seeking to equalize pay and working conditions between the men’s and women’s U.S. national soccer teams. Jeanifer was also named one of Law360’s Sports & Betting “Rising Stars” of 2022 and named as a “Lawyer on the Fast Track” by The Recorder for 2022.
