9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program.
Ancillary 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.
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
