Patent law is the branch of intellectual property law that deals with new inventions. Traditional patents protect tangible scientific inventions, such as circuit boards, car engines, heating coils, or zippers. However, over time patents have been used to protect a broader variety of inventions such as coding algorithms, business practices, or genetically modified organisms.A patent is a form of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of years in exchange for publishing an enabling public disclosure of the invention. In most countries, patent rights fall under private law and the patent holder must sue someone infringing the patent in order to enforce his or her rights. In some industries patents are an essential form of competitive advantage; in others they are irrelevant.
