Career

Charles Sipos represents clients in class-action litigation across the United States, routinely appearing and advocating for defendants in federal courts throughout California, Colorado, the District of Columbia, Florida, Illinois, New Jersey, New York, Massachusetts, Minnesota, Oregon, Washington. He has also argued cases before the U.S. Courts of Appeals for the Second, Seventh, Ninth, and Eleventh Circuits.

Charles' litigation successes have included dismissals and summary judgment based on lack of Article III injury, statutory standing under consumer protection laws, federal preemption, primary jurisdiction, failure to allege damages, First Amendment protections for commercial speech, the "reasonable consumer" standard, and other related defenses.

In the privacy sphere, Charles has litigated claims involving the Video Privacy Protection Act (VPPA), the California Invasion of Privacy Act (CIPA), the Wiretap Act, and alleged violations of privacy policies or related terms of service. He also has deep experience representing consumer goods companies, including the food and beverage industry, dietary supplements, online retailers, and other providers of direct-to-consumer products. He has successfully litigated dozens of class actions raising claims under California's Unfair Competition Law (UCL), California Legal Remedies Act (CLRA), and similar laws in other states. He leverages this substantial experience to provide pre-litigation advice to clients on marketing and privacy issues and associated class-action risk.

Charles also maintains an active IP litigation practice, representing both plaintiffs and defendants in disputes involving false advertising, copyright, trademark, patent infringement, and Digital Millennium Copyright Act (DMCA) claims.

Charles is a frequent speaker and author on class-action topics, and has presented for the Practising Law Institute, Perrin Conferences, CLE International, the Consumer Brands Association, and others. His writings and insights on consumer class-action issues have appeared in publications including Bloomberg News, The Washington Post, The Guardian, the New York Law Journal, and Law360.
