Overview:
A proprietary purchase is one where the specifications or conditions of the proposed purchase are proprietary to one vendor and do not permit an equivalent product or service to be supplied. The term “proprietary” refers to a product or service that has a distinctive feature or characteristic, which is not shared or provided by competing or similar products or services. Proprietary purchases include products or services manufactured or offered under exclusive rights of ownership, including rights under patent, copyright, or trade secret law.
