Keller and Heckman's Litigation practice is led by nationally recognized trial counsel who litigate cases across the United States before federal and state courts for domestic and international clients. We represent interests from a wide range of industries, including chemical; food; drug (prescription, generic, over-the-counter, dietary supplements, and homeopathic products); medical device; cosmetic; consumer products; tobacco and vapor; semiconductor; and telecommunication. The firm defends clients in class and mass tort actions, as well as single plaintiff cases; represents companies in arbitration and mediation proceedings; and serves as national trial coordination counsel. 

We also represent clients before administrative and industry-sanctioned bodies, including companies and individuals subject to investigations and enforcement actions involving the Environmental Protection Agency (EPA) under environmental and chemical regulatory statutes, the Food and Drug Administration (FDA) relating to numerous manufacturing and labeling regimes, the Federal Trade Commission (FTC) for false advertising claims, the Equal Employment Opportunity Commission (EEOC), and Department of Labor (DOL) wage-hour investigations, and the Occupational Safety and Health Administration (OSHA) arising from workplace safety issues. 

Many of our attorneys have scientific and technical backgrounds and have worked in private industry, at state and federal agencies, consulting firms, and in academia. With regulatory lawyers covering numerous disciplines and over 25 Ph.D. and graduate-level scientists and technical specialists residing at our firm, our litigators blend defense capabilities with scientific and regulatory expertise. They map out the most advantageous strategy for clients, whether focusing on early dismissal, securing a favorable settlement, or aggressively defending the case in court. Keller and Heckman’s interdisciplinary approach to problem-solving provides clients the resources for a successful outcome.

We also rely on this expertise in our appellate practice when challenging federal, state, and local laws on various grounds, including under the U.S. Constitution and the Administrative Procedure Act (APA). The firm often represents trade associations and other industry coalitions in key battles involving emerging regulatory issues that potentially impact the manufacturing and consumer product sectors. 

Keller and Heckman represents companies—from multi-national corporations to small businesses—in a full range of commercial litigation, including breach of contract, trade secret disputes, trademark claims, unfair business practices, consumer protection actions, insurance claims, and franchise disputes.
