1.   授予版权许可

每个“贡献者”根据“本许可证”授予您永久性的、全球性的、免费的、非独占的、不可撤销的版权许可，您可以复制、使用、修改、“分发”其“贡献”或“衍生作品”，不论修改与否。

2.   授予专利许可

每个“贡献者”根据“本许可证”授予您永久性的、全球性的、免费的、非独占的、不可撤销的（根据本条规定撤销的情形除外）专利许可，供您使用、制造、委托制造、销售、许诺销售、进口其“贡献”或以其他方式转移其“贡献”。前述专利许可仅限于“贡献者”现在或将来拥有或控制的其“贡献”中的专利权利要求，而不包括仅因您对“贡献”的修改而将必然会侵犯到的专利权利要求。如果您或您的“关联实体”直接或间接地，就“贡献”对任何人发起专利侵权诉讼（包括在诉讼中提出反诉请求或交叉请求）或发起其他专利维权行动，则“贡献者”根据“本许可证”授予您的专利许可自您发起专利诉讼或专利维权行动之日终止。

您可以将您接收到的“贡献”或您的“衍生作品”以源程序形式或可执行形式重新“分发”，但必须满足下列条件：

（1）您必须向接收者提供“本许可证”的副本，并保留“贡献”中的版权、商标、专利及免责声明；并且，

（2）如果您“分发”您接收到的“贡献”，您必须使用“本许可证”提供该“贡献”的源代码副本；如果您 “分发”您的“衍生作品”，您必须：

（i）随“衍生作品”提供使用“本许可证”“分发”的您的“衍生作品”的“对应源代码”。如果您通过下载链接提供前述“对应源代码”，则您应将下载链接地址置于“衍生作品”或其随附文档中的明显位置，有效期自该“衍生作品”“分发”之日起不少于三年，并确保接收者可以获得“对应源代码”；或者，

（ii）随“衍生作品”向接收者提供一个书面要约，表明您愿意提供根据“本许可证”“分发”的您“衍生作品”的“对应源代码”。该书面要约应置于“衍生作品”中的明显位置，并确保接收者根据书面要约可获取“对应源代码”的时间从您接到该请求之日起不得超过三个月，且有效期自该“衍生作品”“分发”之日起不少于三年。

5.   违约与终止

如果您违反“本许可证”，任何“贡献者”有权书面通知您终止其根据“本许可证”授予您的许可。该“贡献者”授予您的许可自您接到其终止通知之日起终止。仅在如下两种情形下，即使您收到“贡献者”的通知也并不终止其授予您的许可：

（1）您在接到该终止通知之前已停止所有违反行为；

（2）您是首次收到该“贡献者”根据“本许可证”发出的书面终止通知，并且您在收到该通知后30天内已停止所有违反行为。

7.   免责声明与责任限制

“贡献”在提供时不带有任何明示或默示的担保。在任何情况下，“贡献者”或版权人不对任何人因使用“贡献”而引发的任何直接或间接损失承担任何责任，不论该等损失因何种原因导致或者基于何种法律理论,即使其曾被告知有该等损失的可能性。
