Actually only the patent license would be terminated, not the
copyright license. If you use Apache in a country where the
patent is not in force, you are not affected by this clause.
Or maybe you have a cross-license with the patent holder.

Anyway, it's my understanding that this part of clause 5 has
be deleted in the next draft.
