The contracting officer shall not include in any solicitation or contract any provision by which the District expressly agrees to indemnify the contractor against liability for patent or copyright infringement or misappropriation of proprietary information.
The contracting officer shall include a clause in all solicitations and contracts that requires a contractor to indemnify the District against infringement of rights in patents, copyrights, or proprietary information and to reimburse the District for any liability incurred as the result of an infringement of rights in patents, copyrights, or proprietary information.
If it is in the best interests of the District to exempt one (1) or more specific United States patents from a patent indemnity clause, the contracting officer may grant the exemption upon written approval of the Director.
