Template:Otheruses4 All Rights Reversed is a phrase that indicates a release of copyright or a copyleft licensing status. It is a pun on the common copyright disclaimer "All Rights Reserved", a formality originally required by the Buenos Aires Convention of 1910. "All Rights Reversed" was used by author Gregory Hill to authorize the free reprinting of his Principia Discordia in the late 1960s. Hill's disclaimer was accompanied by the kosher "Template:Unicode" (for kallisti) symbol, a play on Template:Unicode, the copyright symbol.
In 1984/5 programmer Don Hopkins sent Richard Stallman a letter labeled "Copyleft—all rights reversed". Stallman chose the phrase to identify his free software method of distribution. It is often accompanied by a reversed version of the copyright symbol (see illustration).
