"PATENT CLAIMS" means the claims of patents that are owned or
licensable by Tokutek, both currently or in the future; and that in
the absence of this license would be infringed by THIS
IMPLEMENTATION or by using or running THIS IMPLEMENTATION.
"PATENT CHALLENGE" shall mean a challenge to the validity,
patentability, enforceability and/or non-infringement of any of the
PATENT CLAIMS or otherwise opposing any of the PATENT CLAIMS.
Tokutek hereby grants to you, for the term and geographical scope of
the PATENT CLAIMS, a non-exclusive, no-charge, royalty-free,
irrevocable (except as stated in this section) patent license to
make, have made, use, offer to sell, sell, import, transfer, and
otherwise run, modify, and propagate the contents of THIS
IMPLEMENTATION, where such license applies only to the PATENT
CLAIMS. This grant does not include claims that would be infringed
only as a consequence of further modifications of THIS
IMPLEMENTATION. If you or your agent or licensee institute or order
or agree to the institution of patent litigation against any entity
(including a cross-claim or counterclaim in a lawsuit) alleging that
THIS IMPLEMENTATION constitutes direct or contributory patent
infringement, or inducement of patent infringement, then any rights
granted to you under this License shall terminate as of the date
such litigation is filed. If you or your agent or exclusive
licensee institute or order or agree to the institution of a PATENT
CHALLENGE, then Tokutek may terminate any rights granted to you
under this License.
