Unfair (or disloyal) competition in commercial law is a deceptive business practice that causes economic harm to other businesses or to consumers. It includes a number of areas of law involving acts by one competitor or group of competitors which harm another in the field, and which may give rise to criminal offenses and civil causes of action.
The most common actions falling under the banner of unfair competition include:
- Matters pertaining to antitrust law, known in the European Union as competition law. Antitrust violations constituting unfair competition occur when one competitor attempts to force others out of the market (or prevent others from entering the market) through tactics such as predatory pricing or obtaining exclusive purchase rights to raw materials needed to make a competing product.
- Trademark infringement and passing off, which occur when the maker of a product uses a name, logo, or other identifying characteristics to deceive consumers into thinking that they are buying the product of a competitor. In the United States, this form of unfair competition is prohibited under the common law and by state statutes, and governed at the federal level by the Lanham Act.
- Misappropriation of trade secrets, which occurs when one competitor uses espionage, bribery, or outright theft to obtain economically advantageous information in the possession of another. In the United States, this type of activity is forbidden by the Uniform Trade Secrets Act and the Economic Espionage Act of 1996.
- Trade libel, the spreading of false information about the quality or characteristics of a competitor's products, is prohibited at common law.
- Tortious interference, which occurs when one competitor convinces a party having a relationship with another competitor to breach a contract with, or duty to, the other competitor is also prohibited at common law.
Various unfair business practices such as fraud, misrepresentation, and unconscionable contracts may be considered unfair competition, if they give one competitor an advantage over others. In the European Union, each member state must regulate unfair business practices in accordance with the principles laid down in the Unfair Commercial Practices Directive, subject to transitional periods.
