Hi! I'm writing guidelines for IETF document authors on how to achieve free software compatible copyright and patent licenses [1]. The copyright area is rather well understood, I think; pick any liberal license that is compatible with all (reasonable) free software licenses and you are done.
However, the patent license area seems less clear to me.
Does anyone have some references to any patent license that have been deemed acceptable to some free software projects?
The GPLv3 now embeds a patent license grant so that's one. IIRC Apache and Eclipse license also have patent provisions.
This is the RedHat promise on software patents: http://www.redhat.com/legal/patent_policy.html
Not sure you can call it a license technically, but it is what Red Hat uses to let free software projects use his patents.
Simo.
