If the U.S. Government funds research and specific controls are agreed on to protect information resulting from the research, then information resulting from the project will not be considered fundamental research. Such controls are usually contained in contractual clauses. Examples of "specific controls" include requirements for prepublication “approval” by the Government; restrictions on dissemination of information to non-U.S. citizens or other categories of persons; or restrictions on participation of non-U.S. citizens or other categories of persons in the research.
