Sheppard Mullin routinely represents clients in defending and prosecuting state claims under California's Cartwright Act, Unfair Practices Act and Unfair Competition Law. The firm has significant experience defending clients in such cases, including for instance, defending recent claims brought against energy producers and credit card associations.  We have also defended horizontal price fixing actions, both private actions and those brought by state government enforcement agencies, as well as defended predatory pricing, price gouging and other actions under California's Unfair Practices Act.The firm regularly provides advice to aid clients in complying with competition laws on pricing issues, such as discount, advertising and rebate programs.

While California antitrust law parallels federal antitrust law in many respects, there are important differences. We regularly publish a booklet on California Antitrust and Unfair Competition Law. Sometimes conduct which is permitted under federal law may not be allowed under state law, or vice versa. Sheppard Mullin lawyers maintain expertise in both areas, which allows our firm to provide effective advice in a cost efficient manner.
