WilmerHale has again been named a Law360 Class Action Group of the Year, reflecting the firm’s continued success in defending clients in complex, high‑stakes, and precedent‑setting class actions. The recognition follows Law360’s broader designation of WilmerHale as a 2025 Firm of the Year, reflecting the firm’s strength across six total practice areas—including Appellate, Class Action Compliance, Intellectual Property, Transportation, and Trials—and its record of impactful litigation victories.

“Our class action practice reflects the depth and breadth of our litigation capabilities,” said David Gringer, a New York-based partner. “We focus on cases where the stakes are exceptionally high, the issues are novel, and success requires litigating through discovery, expert challenges, and dispositive motions—often all the way to trial.”

WilmerHale was recognized for advising clients on a range of industry‑shaping class action matters, including:

• Meta Platforms Inc. in a first‑of‑its‑kind antitrust lawsuit seeking more than $156 billion in damages. The case tested a novel theory that a company offering a free product could be required under antitrust law to pay users a so‑called “negative price” in a competitive market. After extensive discovery and expert challenges, WilmerHale secured summary judgment, defeating what would have been the largest antitrust class action in US history had it been certified.
• University of Pennsylvania and other Ivy League institutions in a putative antitrust class action challenging the conference’s long‑standing prohibition on athletic scholarships, securing dismissal of claims that struck at the core of the Ivy League’s academic and athletic model.
• Heinemann, a major publisher, in a novel class action seeking to impose liability on authors and publishers over disputed literacy curricula, with the court granting the firm’s motion to dismiss less than 24 hours after the reply brief was filed.

Class action litigation remains a central focus of WilmerHale’s litigation department. Over the past decade, more than 500 WilmerHale litigators have worked on 300-plus class action matters, spanning virtually every major substantive area, including antitrust, consumer protection, securities, privacy, and higher education. The firm’s class action work is truly nationwide, with matters handled across all U.S. offices by interdisciplinary teams.

“Class actions are a major and growing focus for our firm,” said Sonal Mehta, partner-in-charge of WilmerHale’s Palo Alto office and vice chair of the litigation department. “As these cases become more expansive and more sophisticated, we remain committed to leading the bar in defending clients against the most challenging and high-stakes claims.”
