Intellectual property rights are the rights given to persons over the creations of their minds. They usually give the creator an exclusive right over the use of his/her creation for a certain period of time.
Copyright is the legal right given to an intellectual property owner. As the term suggests, it is the right to copy. Thus, copyright meaning is that when a person creates a product, they own the right to it.
A patent is an exclusive right granted for an invention. Patents benefit inventors by providing them with legal protection of their inventions. However, patents also benefit the society by providing public access to technical information about these inventions, and thus accelerating innovation.
