On one of the contacts I am COR on, the contractor has started marking their charts as copyrighted- including deliverables. The charts are marked as copyrighted by the contractor with all rights reserved. There are no limited rights assertions made by the prime Contractor in the contract. The charts are not marked as proprietary, just copyrighted. I asked about the appropriateness of this marking- they assert that they may mark the charts as copyrighted, quoting the last line:
252.227-7013 (f) Marking requirements. The Contractor, and its subcontractors or suppliers, may only assert restrictions on the Government's rights to use, modify, reproduce, release, perform, display, or disclose technical data to be delivered under this contract by marking the deliverable data subject to restriction. Except as provided in paragraph (f)(5) of this clause, only the following legends are authorized under this contract: the government purpose rights legend at paragraph (f)(2) of this clause; the limited rights legend at paragraph (f)(3) of this clause; or the special license rights legend at paragraph (f)(4) of this clause; and/or a notice of copyright as prescribed under 17 U.S.C. 401 or 402.
Two questions; 1) is this practice acceptable? In other words, does the Government lose any rights on information marked this way? 2) what does the copyright marking accomplish for the Contractor?
