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
