Pioneering National Antitrust Lawyers Based in Philadelphia

Kohn, Swift & Graf’s major influence in antitrust class action lawsuits dates back to the very first cases in the antitrust field. Harold E. Kohn, the firm’s founder, gained national recognition in the early 1960s when he obtained the largest anti-trust verdict ever achieved at that time in the Electric Equipment Antitrust Litigation.

The electric equipment litigation involved hundreds of civil lawsuits brought against several dozen electrical equipment suppliers discovered by the Justice Department to have engaged in a massive price fixing conspiracy. Harold Kohn tried the first of those cases and won a never before achieved $29 million verdict. (In 2017, the $29 million verdict would be valued at more than $230 million.)

In 1981, Kohn, Swift & Graf once again attained an unprecedented victory in the anti-trust field when it won a $2 billion verdict in a plywood industry anti-trust action, the largest anti-trust verdict in history at the time. From its inception to the present day, Kohn, Swift & Graf has maintained its prominent involvement in major antitrust class action lawsuits and is frequently appointed as lead counsel or co-lead counsel in national antitrust litigation.

Antitrust and Unfair Competition Law

Consumers obtain the benefits of lower prices and better products and services only when businesses engage in fair and honest competition. Antitrust and unfair competition laws protect consumers from unfairly high prices and lower quality products and services.

State and federal antitrust and unfair competition laws accomplish this by outlawing activities that interfere with a free, open, and competitive marketplace. Prohibited anti-competitive practices that give rise to litigation handled by our antitrust lawyers include:

⋅  Price Fixing

⋅  Bid Rigging

⋅  Market Division / Customer Allocation

⋅  Exclusive Dealing

⋅  Group Boycotts

⋅  Monopolization

⋅  Price Discrimination

⋅  Tying and Bundling

⋅  Pay for Delay

Price Fixing

Price fixing is an antitrust violation prohibited by state and federal antitrust laws. Price fixing occurs when two or more competitors agree to reduce or eliminate competition for the pricing of goods or services by “fixing” the prices of those goods or services to their customers. Learn more >>

Bid Rigging

Bid rigging occurs when companies that offer bids to win business contracts agree with each other to reduce or eliminate competition for the winning bid. Bid rigging is forbidden by antitrust laws. Learn more >>

Market Division / Customer Allocation

A market division or customer allocation agreement is an agreement among competitors to divide their customers or markets in a designated way. This type of agreement not to compete for specific customers or markets may be contrary to antitrust laws. Learn more >>

Exclusive Dealing

An exclusive dealing arrangement requires a buyer of a particular product or service to purchase from only one seller. An exclusive dealing arrangement that keeps competitors out of a market may violate antitrust laws. Learn more >>

Group Boycotts

Group boycotts are agreements by competitors not to do business with certain individuals or companies. A group boycott that prevents the target of the agreement from competing may constitute an actionable antitrust violation. Learn more >>


Antitrust laws prohibit both monopolization (monopolies) and attempted monopolization achieved through anti-competitive conduct. For an attempted monopolization to violate antitrust laws, the business must intend to acquire and be likely to achieve monopoly power. For an actual monopoly to be in violation of antitrust laws, the business must have intended to both acquire and maintain monopoly power. Learn more >>

Price Discrimination

Price discrimination occurs when different buyers are charged different prices for the same product. Price discrimination that harms or has a substantial risk of harming competition may be in violation of antitrust laws. Learn more >>

Tying / Bundling

Tying or bundling occurs when a seller refuses to sell a particular product or service to a buyer unless the buyer agrees to also purchase a second product or service. Tying / bundling arrangements that have anti-competitive effects may violate antitrust laws. Learn more >>


Pay-for-delay is an agreement between a brand name and generic drug manufacturer. The brand name manufacturer / patent holder pays the generic manufacturer to delay the release of the generic drug to the market. This type of arrangement may violate the Sherman Act by restricting competition. Learn more >>
