Charles Sipos has over fifteen years’ experience litigating complex commercial cases, with a focus on class action litigation and an emphasis on defending consumer protection class actions against food and beverage companies. Charles has successfully defended numerous class actions for food industry clients in courts nationwide, including in California, Illinois, New Jersey, New York, Colorado, Florida and the U.S. Courts of Appeal for the Ninth and Seventh Circuits. He has presented arguments resulting in dismissals and summary judgment based on federal preemption, lack of standing, primary jurisdiction, failure to allege damages and related defenses.

In the class action arena, Charles has experience that extends beyond the food industry. He represents internet service providers, brick and mortar retailers, software companies and video game manufacturers in defense of consumer class actions. Recent successes include a successful argument on behalf of Google, Inc. that resulted in denial of class certification in long-running litigation concerning Google’s privacy policies.

Charles also maintains an active intellectual property practice, representing both plaintiffs and defendants in disputes involving false advertising, copyright, trademark and Digital Millennium Copyright Act (DMCA) claims. He also has substantial appellate experience, and has authored briefing at all levels of the Washington and federal appellate courts, including the United States Supreme Court.
