propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to
receive a copy likewise does not require acceptance. However, nothing other than this License grants you
permission to propagate or modify any covered work. These actions infringe copyright if you do not accept
this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this
License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original
licensors, to run, modify and propagate that work, subject to this License. You are not responsible for
enforcing compliance by third parties with this License.
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of
one, or subdividing an organization, or merging 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.
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
