Intellectual property rights establish minimum standards of protection for intellectual creations of the mind such as inventions, artistic works, symbols, names and images. They usually give the creator exclusive rights over use of the creation for a certain period of time. The main purpose is to encourage creation of a variety of intellectual goods. There are two main forms - literary and artistic works protected by copyright, and industrial property like patented inventions protected by patents, trademarks, industrial designs, trade secrets and geographical indications. World Intellectual Property Organization promotes IP protection globally.
