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.
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 that, but for the
patent license, your conveying the covered work in a country,
or your recipient’s use of the covered work in a country,
would infringe one or more identifiable patents in that country
that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction
or arrangement, you convey, or propagate by procuring
conveyance of, a covered work, and grant a patent license
to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy
of the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work
and works based on it.
A patent license is “discriminatory” if it does not include
within the scope of its coverage, prohibits the exercise of,
or is conditioned on the non-exercise of one or more of
the rights that are specifically granted under this License.
You may not convey a covered work if you are a party to
an arrangement with a third party that is in the business of
distributing software, under which you make payment to the
third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of
the parties who would receive the covered work from you, a
discriminatory patent license
(a) in connection with copies of the covered work conveyed
by you (or copies made from those copies), or
(b) primarily for and in connection with specific products or
compilations that contain the covered work, unless you
entered into that arrangement, or that patent license was
granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or
limiting any implied license or other defenses to infringement
that may otherwise be available to you under applicable
patent law.
12. no Surrender of others’ freedom.
If conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this
License. If you cannot convey a covered work so as to satisfy
simultaneously your obligations under this License and any
other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that
obligate you to collect a royalty for further conveying from
those to whom you convey the Program, the only way you
could satisfy both those terms and this License would be to
refrain entirely from conveying the Program.
13. use with the Gnu affero General public License.
Notwithstanding any other provision of this License, you
have permission to link or combine any covered work with
a work licensed under version 3 of the GNU Affero General
Public License into a single combined work, and to convey
the resulting work. The terms of this License will continue to
apply to the part which is the covered work, but the special
requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will
apply to the combination as such.
14. revised versions of this License.
The Free Software Foundation may publish revised and/ or
new versions of the GNU General Public License from time to
time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or
concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the
GNU General Public License “or any later version” applies to
it, you have the option of following the terms and conditions
either of that numbered version or of any later version
published by the Free Software Foundation. If the Program
does not specify a version number of the GNU General
Public License, you may choose any version ever published
by the Free Software Foundation.
