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 copyright formality originally required by the Buenos Aires Convention of 1910.  "All Rights Reversed" (sometimes spelled rites ) 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 "Ⓚ" (for kallisti ) symbol, a play on ©, 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 ).  That said, this usage is considered legally risky by the Free Software Foundation . 
"All Rights Reversed", its homophone, "All Rites Reversed", and/or the "Copyleft" symbol, are occasionally used among those who publish or produce media (or any other material that might normally be copyrighted) as a clever means of saying "This is not copyrighted. Please, do with it what you will." and encouraging the duplication and use of the "copy-lefted" material thereof.

It is a legal mistake to use a backwards C in a circle instead of a copyright symbol. Copyleft is based legally on copyright, so the work should have a copyright notice. A copyright notice requires either the copyright symbol (a C in a circle) or the word “Copyright”. A backwards C in a circle has no special legal significance, so it doesn't make a copyright notice. It may be amusing in book covers, posters, and such, but be careful how you represent it in a web page!
