10 C.F.R. § 603.865
A TIA's patent rights provision should include the Bayh-Dole march-in rights set out in paragraph (j) of the Patent Rights (Small Business Firms and Nonprofit Organization) provision in Appendix A to subpart D of 10 CFR 600 , or an equivalent clause, concerning actions that the Government may take to obtain the right to use subject inventions, if the recipient fails to take effective steps to achieve practical application of the subject inventions within a reasonable time. The march-in provision may be modified to best meet the needs of the program. However, only infrequently should the march-in provision be entirely removed (e.g., if a recipient is providing most of the funding for a RD&D project, with the Government providing a much smaller share).
