Trent Norris guides manufacturers and retailers of everyday products and services through their toughest challenges. In his litigation, counseling, and government advocacy practice, Trent resolves scientific and technical disputes involving consumer protection, advertising, environmental, and food and drug law, with an emphasis on the unique requirements of California law. 

He brings over 30 years’ experience with regulators, prosecutors, activists, bounty hunters, and plaintiffs’ lawyers to defend clients and provide practical perspectives on litigation avoidance. Trent’s practice involves diverse products, technologies, and industries, such as food, beverages, dietary supplements, cosmetics, hospitality, medical devices, electronics, vehicles, drugs, and agriculture. He defends against consumer class actions, involving allegations of greenwashing, non-functional slack fill, failure to disclose chemicals, mislabeling, and violations of consumer product regulations. And he regularly represents trade associations and joint defense groups in strategic counseling, advocacy before regulatory agencies, and challenges to agency actions. Trent has also advised and defended over a thousand companies regarding California's unique toxics and labeling law, Proposition 65, and California's expansive consumer protection laws.

Trent argues before the California Court of Appeal, the California Supreme Court, and the Ninth Circuit, often facing activist and environmental groups, the California Attorney General, California District Attorneys, and plaintiffs' lawyers. Bringing notable appellate experience, he can handle issues that go beyond the trial court level, such as preemption, commercial speech, interstate commerce, citizen enforcement, jurisdiction, and class action requirements. 

Trent is a registered lobbyist before the California Environmental Protection Agency and its sub-agencies. He served as a legislative aide to a U.S. senator and as an editor of the Harvard Law Review.
