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
