Quality King Distributors, Inc. v. L’anza Research International, Inc.
This case is well known for "legitimizing" the gray market, which is the act of distributing and selling goods in ways not approved by the manufacturer. Quality King Distributors is a well-known and well-established gray marketer, much to the chagrin of L'anza. There are gray markets for everything from computers to tractors, and some manufacturers are lobbying to stop the practice.
