In law, intellectual property is a form of legal entitlement which allows its holder to control the use of certain intangible ideas and expressions. The term intellectual property reflects the fact that once established, such entitlements are generally treated by the law, especially in common law jurisdictions, as if they were tangible property. The most common forms of intellectual property include patents, copyrights, trademarks, and trade secrets. In civil law jurisdictions, intellectual property has often been referred to as intellectual rights, traditionally a somewhat broader concept that has included moral rights and other personal protections that cannot be bought or sold. Use of the term intellectual rights has declined since the early 1980's.

Intellectual property rights may exist either for an indefinite period of time, or they may last for a term of years, after which they typically expire and become part of the public domain. These rights are governed by the law of the sovereign nation in which the intellectual property was created or established. Traditionally, each nation established and enforced its own intellectual property rights; however, beginning with the Paris Convention for the Protection of Industrial Property in 1883, numerous treaties have provided for cross-border protections, multinational procedures, and increasing uniformity. Since its establishment in 1967, the Geneva-based World Intellectual Property OrganizationThe World Intellectual Property Organization (WIPO) is an international organization devoted to protecting intellectual property. WIPO is one of the specialized agencies of the United Nations. It has 181 member states, and administers 21 international tre (WIPO) has become the world's central organization for promoting internationalism in intellectual property.

1 Overview

The purposes of exclusive rights laws have varied, but they nevertheless have the appearance of granting the "owner" a monopoly on copying or distribution of a protected form of "property". This was done originally to grant a boon to a king's favourite (with some positive advantages to the public, since often these grants were prerequisites before a merchant would undertake production). The United States Constitution accords Congress the power to promote the progress of science and the useful arts by granting exclusive rights to authors and inventors for limited times.

The use of the term "intellectual property" is often predicated on considerations such as the " free rider problemIn the analyses of economics and political science, free riders are actors who take more than their fair share of the benefits or do not shoulder their fair share of the costs of their use of a resource, involvement in a project, etc. The free rider probl" or rationalized by problematizing the fact that owners of computers have the ability to produce and distribute perfect copies of digital works. Proponents of the term tend to address exclusive rights policy by valorizing the incentives afforded to authors and inventors in granting them a right to exact a fee from those who wish to manufacture their inventions or publish their expressive works. The analyses associated with the term tend to overlook or even to attempt to defeat the fact, noted by Thomas Jefferson when he took part in wording the exclusive rights clause, that published information is intrinsically free and that in fact this is the whole point of exclusive rights -- to publish, to provide information to the public.

By an economic analysis, the incentives granted for patent rights have sometimes served the public benefit purpose (and promoted innovation) by ensuring that someone who devoted, say, ten years of penury while struggling to develop vulcanized rubber or a workable steamship, could recoup her or his investment of time and energy. Using monopoly power, the inventor could exact a fee from those who wanted to make copies of his or her invention. Set it too high, and others would simply try to make a competing invention, but set it low enough and one could make a good living from the fees.

In latter years, the public benefit idea has been downplayed in favor of the idea that the primary purpose of exclusive rights is to benefit the rightsholder, even to the detriment of society at large; and this development has attracted some opponents.

In some fields, patent law has had an unintended, indeed, a perverse consequence: treating abstract rules and mental products like concrete ones has stifled innovation in those fields, rather than aiding it.

The four main types of non-physical things considered by this point of view are copyrights, patents, trademarks and trade secrets. Common types of intellectual property rights include conflicting areas of law:

These rights, conferred by law, can be given, sold, rented (called " licensing") and, in some countries, even mortgageIntro A mortgage is a device used to create a lien on real estate by contract. The mortgage is an instrument that the borrower (called the mortgagor) uses to pledge real property to the lender (called the mortgagee) as security for a debt, also called hypd, in much the same way as physical property (especially real property). However, the rights have limitations, including term limits and other considerations (such as intersections with fundamental rights and the codified provisions for fair use for copyrighted works). Some analogize these considerations to public easements, since they grant the public certain rights which are considered essential.

It is important to understand that authors and inventors exercise specific rights, and the "property" referred to in "intellectual property" is the rights, not the intellectual work. A patent can be bought and sold, but the invention that it covers is not owned at all. This is one of many reasons that the term intellectual property is misleading. Some use the term "intellectual monopoly" instead, because such so-called "intellectual property" is actually a government-granted monopoly on certain types of action. Others object to this usage, because this still encourages a natural rights notion rather than a recognition that the rights are purely statutory, and it only characterizes the "property" rather than eliminates the property presupposition. Others object to the negative connotation of the term " monopoly" and cite the wide availability of substitute goods. Still others prefer not to use a generic term because of differences in the nature of copyright, patent and trademark law, and try to be specific about which they are talking about. The term "exclusive rights" reflects the Constitutional language and actually serves very well as a general term that much more precisely represents the nature of this area of law.
