Under an OTA, IP and Data Rights are negotiated on a project-by-project basis prior to the final agreement. Each solicitation provides the SUPPLEMENTAL INTELLECTUAL PROPERTY & PATENT RIGHTS AGREEMENT (SIPRA) for review and completion to be submitted with your solution for Government consideration and evaluation. Consideration is given to existing IP and data. Commercial and proprietary IP and data developed prior to engagement on specific prototype efforts remain the sole property of the vendor.
