48 C.F.R. § 27.407
The clause at 52.227-23, Rights to Proposal Data (Technical), allows the Government to acquire unlimited rights to technical data in successful proposals. Pursuant to the clause, the prospective contractor is afforded the opportunity to specifically identify pages containing technical data to be excluded from the grant of unlimited rights. This exclusion is not dispositive of the protective status of the data, but any excluded technical data, as well as any commercial and financial information contained in the proposal, will remain subject to the policies in Subpart 15.2 or 15.6 (or agency supplements) relating to proposal information ( e.g. , will be used for evaluation purposes only). If there is a need to have access to any of the excluded technical data during contract performance, consideration should be given to acquiring the data with limited rights, if they so qualify, in accordance with 27.404-2(c).
