The aspect of law which allows an exclusive right for a limited number of years is called a patent. A patent is a legal right granted to an inventor that gives them the exclusive right to make, use, and sell their invention for a limited period of time. The purpose of a patent is to encourage innovation by providing inventors with the ability to profit from their creations and protect their intellectual property. Copyright, on the other hand, is a form of intellectual property protection that applies to creative works such as books, music, and films. Trademarks protect words, phrases, symbols, or designs that distinguish the goods or services of one company from those of another. Raffication is not a recognized term in law.
