The legal document that gives an individual power to protect their own piece of invention is called a patent right. A patent is a type of intellectual property that gives the inventor the exclusive right to prevent others from making, using, selling, or importing their invention for a certain period of time, usually 20 years from the date of filing. In order to be granted a patent, the invention must meet certain requirements, including being novel, useful, and non-obvious. Having a patent gives the inventor legal protection and the right to license or sell their invention to others. It also helps to prevent others from stealing or copying their invention without permission, which can help to ensure that the inventor is able to profit from their hard work and creativity. In summary, a patent right is a legal document that gives an individual the exclusive right to protect their own invention, preventing others from using, making, or selling it without their permission.
