Intellectual property or IP refers to certain kinds of exclusive rights to intellectual capital, some forms of which can expire after a set period of time, and other forms of which can last indefinitely. Common types of intellectual property rights include conflicting areas of law:

Copyrights, which give the holder some exclusive rights to control some reproduction of works of authorship, such as books and music, for a certain period of time.

Patents give the holder an exclusive right to use and license use of an invention for a certain period, typically 20 years from the filing date of a patent application.

Trademarks are distinctive names, phrases or marks used to identify products to consumers.

Trade secrets, where a company keeps information secret, perhaps by enforcing a contract under which those given access to information are not permitted to disclose it to others.

These rights, conferred by law, can be given, sold, rented (called \"licensing\") and, in some countries, even mortgaged, in much the same way as physical property. However, the rights typically have limitations, sometimes including term limits and other exceptions (such as fair use for copyrighted works.)
