the predecessor has it or can get it with reasonable efforts.                

               

 You may not impose any further restrictions on the exercise of the                

rights granted or affirmed under this License.  For example, you may                

not impose a license fee, royalty, or other charge for exercise of                

rights granted under this License, and you may not initiate litigation                

(including a cross-claim or counterclaim in a lawsuit) alleging that                

any patent claim is infringed by making, using, selling, offering for                

sale, or importing the Program or any portion of it.                

               

 11. Patents.                

               

 A "contributor" is a copyright holder who authorizes use under this                

License of the Program or a work on which the Program is based.  The                

work thus licensed is called the contributor's "contributor version".                

               

 A contributor's "essential patent claims" are all patent claims                

owned or controlled by the contributor, whether already acquired or                

hereafter acquired, that would be infringed by some manner, permitted                

by this License, of making, using, or selling its contributor version,                

but do not include claims that would be infringed only as a                

consequence of further modification of the contributor version.  For                

purposes of this definition, "control" includes the right to grant                

patent sublicenses in a manner consistent with the requirements of                

this License.                

               

 Each contributor grants you a non-exclusive, worldwide, royalty-free                

patent license under the contributor's essential patent claims, to                

make, use, sell, offer for sale, import and otherwise run, modify and                

propagate the contents of its contributor version.                

               

 In the following three paragraphs, a "patent license" is any express                

agreement or commitment, however denominated, not to enforce a patent                

(such as an express permission to practice a patent or covenant not to                

sue for patent infringement).  To "grant" such a patent license to a                

party means to make such an agreement or commitment not to enforce a                

patent against the party.                

               

 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
