Section 27.305-3 - Securing invention rights acquired by the Government(a) Agencies are responsible for implementing procedures necessary to protect the Government's interest in subject inventions. When the Government acquires the entire right, title, and interest in an invention by contract, the chain of title from the inventor to the Government shall be clearly established. This is normally accomplished by an assignment either from each inventor to the contractor and from the contractor to the Government, or from the inventor to the Government with the consent of the contractor. When the Government's rights are limited to a license, there should be a confirmatory instrument to that effect.(b) Agencies may, by supplemental instructions, develop suitable assignments, licenses, and other papers evidencing any rights of the Government in patents or patents applications. These instruments should be recorded in the U.S. Patent and Trademark Office (see Executive Order 9424, Establishing in the United States Patent Office a Register of Government Interests in Patents and Applications for Patents, (February 18, 1944).
