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
