patents to make, have made, use, sell, offer for sale, import, and/or otherwise dispose of its contribution 
in the software or derivative works of the contribution in the software. 3. Conditions and Limitations 
(A) No Trademark License- This license does not grant you rights to use any contributors' name, logo, or trademarks. 
(B) If you bring a patent claim against any contributor over patents that you claim are infringed by the software, 
your patent license from such contributor to the software ends automatically. (C) If you distribute any portion of

license. (E) The software is licensed "as-is." You bear the risk of using it. The contributors give no express 
warranties, guarantees or conditions. You may have additional consumer rights under your local laws which 
this license cannot change. To the extent permitted under your local laws, the contributors exclude the 
implied warranties of merchantability, fitness for a particular purpose and non-infringement.
