Proprietary Specification
Definition
A specification that restricts the acceptable product(s) or service(s) to that of one or more manufacturer(s) or vendor(s). A common example would be the use of a “brand name” specification that would exclude consideration of proposed “equals.” Although all sole source specifications are proprietary, all proprietary specifications are not the sole source. Proprietary items may be available from several distributors through competitive bidding.
