A patent is a property right for an invention granted by a government to the inventor. A United States patent gives inventors the right "to exclude others" from making, using, offering for sale, or selling their invention throughout the United States or importing their invention into the United States. In exchange for this monopolistic protection, the inventor must publicly disclose the invention (the patent document) and must pay the United States Patent Office (USPTO.gov) to prosecute (application fees) and maintain (maintenance fees) the patent.
