The additional Patents clause can simply be disregarded or, if not, then just file a patent lawsuit against Facebook. The plain BSD license does not offer a patent grant so there is no incompatibility.

The Apache Software License does grant a patent license [0] (as does GPLv3) so is incompatible with either of these BSD licenses (unless an 'implied' grant is assumed).
