"Intellectual property (IP) is a category of property that includes intangible creations of the human intellect."
The law governing the protection of intangible creations of the mind, such as inventions, literary and artistic works, and symbols or designs.
"There are many types of intellectual property."
"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."
"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."
"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."
"The intangible nature of intellectual property presents difficulties when compared with traditional property like land or goods."
"Unlike traditional property, intellectual property is 'indivisible,' since an unlimited number of people can in theory 'consume' an intellectual good without its being depleted."
"Producers of information or literature can usually do little to stop their first buyer from replicating it and selling it at a lower price."
"Balancing rights so that they are strong enough to encourage the creation of intellectual goods but not so strong that they prevent the goods' wide use is the primary focus of modern intellectual property law."
