Open Source License FAQ

We use a standard BSD license paired with an additional patent grant for most of our open source projects. For brevity, we call this combination the Facebook BSD+Patents license. We've compiled some answers to common questions about the additional patent grant:

Does the additional patent grant in the Facebook BSD+Patents license terminate if I create a competing product?

No.

Does the additional patent grant in the Facebook BSD+Patents license terminate if I sue Facebook for something other than patent infringement?

No.

Does the additional patent grant in the Facebook BSD+Patents license terminate if Facebook sues me for patent infringement first, and then I respond with a patent counterclaim against Facebook?

No, unless your patent counterclaim is related to Facebook's software licensed under the Facebook BSD+Patents license.

Does termination of the additional patent grant in the Facebook BSD+Patents license cause the copyright license to also terminate?

No.
