Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. There are many types of intellectual property, and some countries recognize more than others. The best-known types are patents, copyrights, trademarks, and trade secrets. The modern concept of intellectual property developed in England in the 17th and 18th centuries. The term "intellectual property" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in most of the world's legal systems.
Supporters of intellectual property laws often describe their main purpose as encouraging the creation of a wide variety of intellectual goods. To achieve this, the law gives people and businesses property rights to certain information and intellectual goods they create, usually for a limited period of time. Supporters argue that because IP laws allow people to protect their original ideas and prevent unauthorized copying, creators derive greater individual economic benefit from the information and intellectual goods they create, and thus have more economic incentives to create them in the first place. Advocates of IP believe that these economic incentives and legal protections stimulate innovation and contribute to technological progress of certain kinds.
