"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of, publicly

only to those patent claims licensable by such Contributor that are
necessarily infringed by their Contribution(s) alone or by combination
of their Contribution(s) with the Work to which such Contribution(s)
was submitted. If You institute patent litigation against any entity
(including a cross-claim or counterclaim in a lawsuit) alleging that the
Work or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses granted
to You under this License for that Work shall terminate as of the date
such litigation

the following conditions:
a. You must give any other recipients of the Work or Derivative Works a
copy of this License; and
b. You must cause any modified files to carry prominent notices stating
that You changed the files; and
c. You must retain, in the Source form of any Derivative Works that You
distribute, all copyright, patent, trademark, and attribution notices from
the Source form of the Work, excluding those notices that do not pertain

d. If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must include
a readable copy of the attribution notices contained within such NOTICE
file, excluding those notices that do not pertain to any part of the
Derivative Works, in at least one of the following places: within a
NOTICE text file distributed as part of the Derivative Works; within the
Source form or documentation, if provided along with the Derivative
Works; or, within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents of the

Works that You distribute, alongside or as an addendum to the NOTICE
text from the Work, provided that such additional attribution notices
cannot be construed as modifying the License.
