"THIS IMPLEMENTATION" means the copyrightable works distributed by
57
Tokutek as part of the Fractal Tree project.
59
"PATENT CLAIMS" means the claims of patents that are owned or
60
licensable by Tokutek, both currently or in the future; and that in
61
the absence of this license would be infringed by THIS
62
IMPLEMENTATION or by using or running THIS IMPLEMENTATION.
64
"PATENT CHALLENGE" shall mean a challenge to the validity,
65
patentability, enforceability and/or non-infringement of any of the
66
PATENT CLAIMS or otherwise opposing any of the PATENT CLAIMS.
68
Tokutek hereby grants to you, for the term and geographical scope of
69
the PATENT CLAIMS, a non-exclusive, no-charge, royalty-free,
70
irrevocable (except as stated in this section) patent license to
71
make, have made, use, offer to sell, sell, import, transfer, and
72
otherwise run, modify, and propagate the contents of THIS
73
IMPLEMENTATION, where such license applies only to the PATENT
74
CLAIMS. This grant does not include claims that would be infringed
75
only as a consequence of further modifications of THIS
76
IMPLEMENTATION. If you or your agent or licensee institute or order
77
or agree to the institution of patent litigation against any entity
78
(including a cross-claim or counterclaim in a lawsuit) alleging that
79
THIS IMPLEMENTATION constitutes direct or contributory patent
80
infringement, or inducement of patent infringement, then any rights
81
granted to you under this License shall terminate as of the date
82
such litigation is filed. If you or your agent or exclusive
83
licensee institute or order or agree to the institution of a PATENT
84
CHALLENGE, then Tokutek may terminate any rights granted to you
