O ABORDARE JURIDICĂ A LICENȚELOR COPYLEFT.

Considering the alert evolution of the technical industry and especially of the software industry, the importance of the existence of free software is crucial, thus giving the new software developers the opportunity to start developing the new and advanced software starting from that already created by their colleagues. The aim of this paper is to present the methods of creating free software, with special emphasize on the copyleft licenses which grant the beneficiary of the license the four essential freedoms: the freedom to run, copy, distribute, study, change or improve the software.
