It is just like a property right for the inventor. All U.S. patents are issued by the United States Patent and Trademark Office or USPTO. Most patents last for twenty years. The twenty years begins on the date the application for a non-provisional or provisional patent was first filed. A patent gives you the right to exclude others from making, using, offering for sale, or selling your invention in the United States or importing your invention into the United States. Once a patent is issued, it becomes your responsibility to enforce the patent, the USPTO will not enforce your rights for you. From the USPTO you are only granted rights that are honored within the United States, U.S. territories, and U.S. possessions.
