48 C.F.R. § 227.672
It is Government policy not to pay in connection with its contracts, and not to allow to be paid in connection with contracts made with funds derived through the Military Assistance Program or otherwise through the United States Government, charges for use of patents in which it holds a royalty-free license or charges for data which it has a right to use and disclose to others, or which is in the public domain, or which the Government has acquired without restriction upon its use and disclosure to others. This policy shall be applied by the Departments in negotiating contract prices for foreign license technical assistance contracts (227.675) or supply contracts with second sources (227.674); and in commenting on such agreements when they are referred to the Department of Defense by the Department of State pursuant to section 414 of the Mutual Security Act of 1954 as amended ( 22 U.S.C. 1934 ) and the International Traffic in Arms Regulations (see 227.675).
