A patent for an invention is the grant of a property right to the inventor. Generally, the term of a new patent is 20 years from the date on which the application for the patent was filed in the United States. There are three types of patents: (1) Utility, covering function; (2) Design, covering ornamental design; and (3) Plant, for a new variety of plant.
