In general, if you develop intangible property under a fellowship agreement (e.g., copyrighted software), EPA reserves a royalty-free, nonexclusive and irrevocable right to reproduce, publish, or otherwise use the work for Federal purposes, and to authorize others to do so. EPA's requirements for dealing with such intangible property are found at 2 CFR 200.315 .
