Can the USPTO assist me in the developing and marketing of my patent?

The USPTO cannot act or advise concerning the business transactions or arrangements that are involved in the development and marketing of an invention. The Office, however, will publish for a fee, at the request of a patent owner, a notice in the Official Gazette that the patent is available for licensing or sale. In addition, the Office of Independent Inventor Programs (OIIP) was established in March 1999 in order to meet the special needs of independent inventors. The OIIP establishes new mechanisms to better disseminate information about the patent and trademark processes and to foster regular communication between the USPTO and independent inventors.
