Patents:

A patent for an invention is the grant of a property right to the inventor, issued by the United States Patent and Trademark Office (USPTO). The right conferred by the patent grant is “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States or “importing” the invention into the United States for a limited time in exchange for public disclosure of the invention when the patent is granted. Patents are territorial in that patent protection must be applied for in each country where protection is sought.
