Warranty often implied into contracts under common law, that a purchaser of goods (or land and buildings) will be able to use the goods without being harassed by third parties with claims against ownership or use of the goods. English case law has held that a buyer of goods that are subsequently subject to a claim of infringing intellectual property rights may have a claim against the vendor for breach of this warranty (Microbeads AG and Another v. Vinhurst Road Markings Ltd. [1975] 1 All E.R. 529).
