On December 21, 2020, the Federal Circuit decided The Boeing Company v. Secretary of the Air Force.[1] The case was an appeal by Boeing of a denial of summary judgment and final judgment of the Armed Services Board of Contract Appeals (the Board) regarding certain legends that Boeing marked on its documents containing technical data delivered to the US Department of the Air Force with unlimited rights under government contracts. The Federal Circuit reversed the Board’s denial, finding that defense contract requirements for legends on technical data submitted to the government do not apply to legends that restrict only third-party rights.
