The wording of the complaint heavily angles that way.
People use F13 as an example of it killing the franchise, but the problem there is there's a huge contention over whether the provision was even allowed to be invoked in the first place. The original F13 script was written on request of the producer, Sean Cunningham, which would make it work-for-hire -- but because they never made a formal written agreement calling it that, the author said it was legally a spec script.
