A patent for an invention is the grant of a property right to the inventor, issued by the United States Patent and Trademark Office.
- The term of a new patent is generally 20 years from the date on which the application for the patent was filed in the United States, but there are special cases.
- It is only valid in the country in which it was issued. So, U.S. patent grants are effective only within the United States, U.S. territories, and U.S. possessions.
- A patent confers the right to exclude others from making, using, offering for sale, selling or importing the invention.
- Once a U.S. patent is issued, the patentee must enforce the patent without aid of the USPTO.
