I also have a feeling they'll try to jam the courts, producing civil suit after civil suit. Many will be seemingly ridiculous assertions or accusations where they can't win. But if you throw enough ca-ca, some of it will stick and it will surely drive everyone else out of the neighborhood. This suit against Fox seems to be of that nature-it's a ridiculous assertion on the face of it, but they can tie up Fox resources, take their energy, and manage to raise doubts about them.
