The Eclipse Public License

OSI compliance

The EPL is a fully OSI compliant license.

License type

The EPL is a reciprocal license. with a strong Copyleft


The EPL gives patent grants to the original work and to enhanced versions based on the original work, but not to other code. The EPL contains rules that help to defend against patent trolls.

The EPL in collaborative works

The EPL permits only contributions and anhancements to the original work but does not allow to use code from a EPL licensed work in another work. So the EPL is even more restrictive than the GPL.

For this reason, the OSSCC does not recommend to use the EPL for new projects.
