Good licence, has anti-swpat clause

[ciaran_o_riordan]

Among the permissive licences, Apache 2.0 has the best patent retaliation clause:

• http://en.swpat.org/wiki/Patent_clauses_in_software_licences#Apache_License

If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.
