The Invention Secrecy Act of 1951 requires the government to impose "secrecy orders" on certain patent applications that contain sensitive information, thereby restricting disclosure of the invention and withholding the grant of a patent. Remarkably, this requirement can be imposed even when the application is generated and entirely owned by a private individual or company without government sponsorship or support. Invention Secrecy
There are several types of secrecy orders which range in severity from simple prohibitions on export (but allowing other disclosure for legitimate business purposes) up to classification, requiring secure storage of the application and prohibition of all disclosure.
At the end of fiscal year 2009, there were 5,081 secrecy orders in effect.
