Applicants for licenses to NRC inventions are required to provide information which may provide the basis for granting the requested license. In addition, all license holders must submit periodic reports on efforts to bring the invention to a point of practical application and the extent to which they are making the benefits of the invention reasonably accessible to the public. Exclusive license holders must submit additional information if they seek to extend their licenses, issue sublicenses, or transfer the licenses. In addition, if requested, exclusive license holders must promptly supply to the United States Government copies of all pleadings and other papers filed in any patent infringement lawsuit, as well as evidence from proceedings relating to the licensed patent.
