The application for a patent is accompanied by an oath that the inventor believes herself to be the first and original inventor. The patent laws of the United States do not discriminate on the basis of the citizenship of the inventor. An inventor from another country may apply for a patent on the same basis as a U.S. citizen. An application for an original patent must be accompanied by a filing fee payable to the Patent and Trademark Office. Fees vary depending upon the type of application and the size of the entity applying for the patent.
Small entities pay lower fees.
When a patent is issued, the patentee must pay an additional fee. These fees also vary based on the size of the entity to whom the patent is issued. Additional fees are charged for maintaining a patent, which likewise vary with the size of the entity involved in the maintenance of the patent.
