U.S. patents give an inventor exclusive rights on the invention. The exclusive rights will prevent others to make, use, import, sell or offer to sell the invention without the inventor’s permission. In exchange for this grant, the inventors must disclose their invention to the public in the form of a patent application. U.S. patents do not grant inventors the right to make, use, sell, or import their inventions — only to exclude others from doing so.
