Appendix E Open Source Licences
organizations. If propagation of a covered work results from an entity transaction,
each party to that transaction who receives a copy of the work also receives
whatever licenses to the work the party's predecessor in interest had or could give
under the previous paragraph, plus a right to possession of the Corresponding
Source of the work from the predecessor in interest, if the predecessor has it or
can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted
or affirmed under this License. For example, you may not impose a license fee,
royalty, or other charge for exercise of rights granted under this License, and you
may not initiate litigation (including a cross-claim or counterclaim in a lawsuit)
alleging that any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the
Program or a work on which the Program is based. The work thus licensed is called
the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled
by the contributor, whether already acquired or hereafter acquired, that would be
infringed by some manner, permitted by this License, of making, using, or selling
its contributor version, but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For purposes of
this definition, "control" includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent
license under the contributor's essential patent claims, to make, use, sell, offer for
sale, import and otherwise run, modify and propagate the contents of its
contributor version.
In the following three paragraphs, a "patent license" is any express agreement or
commitment, however denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to sue for patent infringement). To
"grant" such a patent license to a party means to make such an agreement or
commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free of
charge and under the terms of this License, through a publicly available network
server or other readily accessible means, then you must either (1) cause the
Corresponding Source to be so available, or (2) arrange to deprive yourself of the
benefit of the patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent license to
downstream recipients. "Knowingly relying" means you have actual knowledge
