Unless contract bided, the creater holds all rights to their work and retains rights to copyright. Ideas must be orignal to claim copyright and not be copied or developed from another source. The idea itself cannot be copyrighted, it must be a physical aspect in order to gain copyright, for example a book or product that has been created.

Copyleft is therefore the oppostite to copyright and the name represents a play on words and the logo has been reversed.
