The Common Public License
is superseeded by the
Eclipse Public License.
The CPL is a fully OSI compliant license.
The CPL is a reciprocal license. with a strong Copyleft
The CPL gives patent grants to the original work and to enhanced versions based
on the original work, but not to other code.
The CPL contains rules that help to defend against patent trolls.
The CPL in collaborative works
The CPL permits only contributions and anhancements to the original work but does not allow
to use code from a CPL licensed work in another work. So the CPL is even more restrictive than the GPL.
For this reason, the OSSCC does not recommend to use the CPL for new projects.
