Law360 (subscription) has published an in-depth profile on Lieff Cabraser as part of its recognition of the firm as a 2025 “Class Action Law Practice Group of the Year.” The firm’s sole focus is plaintiff-side class actions and other forms of mass litigation, a dedication that has defined its more than 50-year history. As the article notes, these recent victories reflect Lieff Cabraser’s commitment to using class action litigation to secure meaningful change for communities, consumers, and workers alike. The piece highlights the firm’s success in achieving several high-profile settlements in opioid litigation, artificial intelligence and copyright law cases, and matters of online privacy.
Among the cases featured, Law360 emphasizes Lieff Cabraser’s role in securing final court approval of a $300 million settlement on behalf of third-party payors in the nationwide opioid multidistrict litigation. The settlement, funded by major opioid distributors, resolved claims brought by private benefit plan providers that alleged they incurred billions of dollars in costs associated with opioid prescriptions and treatment resulting from opioid addiction. The profile also notes the firm’s efforts generally to develop innovative settlement structures in complex, large-scale public health litigation.
The profile also highlights Lieff Cabraser’s success in cutting-edge litigation involving artificial intelligence and intellectual property rights. In September 2025, the firm obtained a $1.5 billion settlement on behalf of authors and copyright holders in litigation against Anthropic, challenging the use of copyrighted works without compensation to train its artificial intelligence chatbot. The settlement is the largest AI-related copyright resolution to date and underscores the firm’s leadership in emerging technology litigation.
The profile further notes Lieff Cabraser’s work in high-profile privacy litigation against Oracle, which was accused of collecting and selling consumer data without consent through extensive tracking and profiling practices. The litigation resulted in changes to Oracle’s data collection practices, reinforcing longstanding privacy protections in the rapidly evolving digital economy.
