Intellectual property rights, also known as "intellectual property rights", refer to "the property rights enjoyed by the obligee on the fruits of intellectual labor created by him", which are generally valid only for a limited period of time. All kinds of intellectual creations, such as inventions, literary and artistic works, and signs, names, images and designs used in business, can be regarded as intellectual property rights owned by a certain person or organization. According to Professor Mark Lemley of Stanford University Law School, the word "intellectual property" was widely used after the establishment of 1967 World Intellectual Property Organization.
