Calfee’s antitrust and trade regulation team provides proactive and trusted guidance so that our clients can address potential competition issues before they become legal problems. We regularly represent public and private companies on antitrust matters in every procedural context – before the Federal Trade Commission, U.S. Department of Justice, and in state and federal courts in complex civil and criminal litigation. 

We give clients practical competition advice that allows them to achieve their business goals while limiting their legal exposure in areas such as distribution, price, and acquisitions.

The industries in which we provide antitrust counsel are as diverse as the firm’s client base and have included consumer goods, automotive components, food and beverage, health care, real estate brokerage, software development, supermarkets, electric utilities, industrial coatings, mining, and dairies.

We provide counseling and litigation services in the areas of competitor and customer relations, pricing policies, dealer relations, Hart-Scott-Rodino compliance, joint venture/acquisition analysis, advertising and franchising. We also regularly assist clients in developing and implementing antitrust compliance programs.

In the context of antitrust law, the question often is not whether conduct is plainly legal or illegal but the degree of risk of liability it may carry. Assessing that risk involves more than just knowledge of the law. It also requires an experienced assessment of how a judge or jury will perceive the conduct, how state and federal antitrust enforcement authorities will view it, and a sensitivity for the particular client’s business objectives.

The stakes in antitrust litigation are often are enormous. Substantial resources usually must be brought to bear in prosecution or defense of such claims. At Calfee, we have the resources and the experience necessary to employ these resources efficiently and effectively.

Effective antitrust representation also requires a thorough understanding of the specific marketplace in which a business operates. Our knowledge spans a vast range of industries, and we work with clients to ensure we understand their businesses in order to effectively guide them through the antitrust maze to achieve their business goals.
