This is the first book to comprehensively integrate business torts (also known as economic torts) and unfair competition actions. The book covers all of the major tort causes of action that one might see in a commercial litigation practice, including the economic loss rule, fraud, negligent misrepresentation, tortious interference with contract and prospective contract, breach of fiduciary duty, insurance torts, breach of the duty of good faith, deceptive marketing, commercial disparagement, misappropriation, trade secrets, trademark infringement, antitrust, and civil RICO. The book also covers important state, federal, and model provisions, including the Second and Third Restatement of Torts, the Third Restatement of Unfair Competition, the Restatement of the Law of Liability Insurance, the Lanham Act, the Uniform Trade Secrets Act, and the Defend Trade Secrets Act. The authors have included numerous questions and problems to further students' thinking on more complex topics.
