Lessig argues that the current system of copyright laws provides little flexibility — either you give up all permissions for use of your work or you withhold everything. He proposed a solution: a set of copyright licenses that would allow artists to choose to keep “some rights reserved” rather than “all rights reserved.”
They could, for instance, choose to allow their works to be enjoyed and copied by others for any purpose, restrict such activity to non-commercial use or allow use of portions of the work rather than all of it. To that end, Lessig co-founded the nonprofit Creative Commons, whose aim, as he describes it, is to “help artists and authors give others the freedom to build upon their creativity — without calling a lawyer first.”
