https://github.com/facebookincubator/beringei/blob/master/LICENSE https://github.com/facebookincubator/beringei/blob/master/LI... doesn't even mention patents. https://github.com/facebookincubator/beringei#license https://github.com/facebookincubator/beringei#license says "We also provide an additional patent grant." None of this sounds to me like you have to grant Facebook any patents to use Beringei.
