A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time (usually 20 years) in exchange for public disclosure of the invention when the patent is granted.
This right was established over 200 years ago in Article 1, Section 8 of the United States Constitution: “To promote the progress of science and useful arts, by securing for limited times to authors and Inventors the exclusive right to their respective writings and discoveries.”
