Section 606(c) of the Foreign Assistance Act bars procurement by the Government of drug and pharmaceutical products manufactured outside the United States if their manufacture involves the use of or is covered by an unexpired U.S. patent which has not been held invalid by an unappealed or unappealable court decision unless the manufacture is expressly authorized by the patent owner. Applicable policies and procedures are set forth in USAID Automated Directive System Chapter 312.
