I think the point being discussed is: Who has the right to control
the reporductions, performances, displays and distribution OF
derivative works that are made under license from the original creator:
the original creator (A), or the creator of the derivative work (B)?
In particular, if B has any rights as against the world, does he
also have rights against A?

If I write a novel, and you make it into a film under license from
me, I can't make copies of the film without a cross-license from you, no?
If the film;s copyright is infringed, only you can sue, no?
