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.
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.
