What is the United States Patent and Trademark Office (PTO)?
A. The PTO is the federal agency, organized under the Department of Commerce, that administers patents on the part of the government. (A part of the PTO also issues federal trademark registrations.) A description of the PTO may be found at http://www.uspto.gov/web/offices/pac/doc/general/index.html#uspto. Although the PTO issues patents, patents must be enforced in the federal court system of the United States.
