Nobodies ever found one, and a core React dev is on record saying he doesn't know of any either. :) But you don't ever your license to use React. Bonus: Many people think the BSD license contains an implicit patent grant, which might well cover you even if the explicit patent grant is revoked. Again, if there are any patents to license.
