Whether defending the world's largest semiconductor chip maker against allegations of anti-competitive recruiting practices or a major consumer goods manufacturer in a billion-dollar false advertising case, Munger Tolles represents clients in a wide variety of class actions. Our lawyers represent companies in industries such as technology, pharmaceuticals and financial services, considering each marketplace’s unique dynamics and bringing novel thinking to every case.

Recognized as a Law360 Class Action Group of the Year for legal victories on behalf of Bank of America, Philip Morris USA and Transocean, Munger Tolles attorneys are skilled at untangling the complex intricacies of each case and developing creative strategies to bring current or potential class actions to a swift and favorable resolution. 

The firm is known for delivering innovative legal strategies and extraordinary results in class action litigation.
