They're suing to be able to use the name without paying Fizzer royalties or whatever. If they win, both games continue to be called Warzone
It has nothing to do with royalties. If they get the trademark, they can go to Apple + Google and say "Hey this app is named Warzone, and we have the registered trademark for Warzone, please delete the apps" and then poof, Warzone is gone. I had no choice but to oppose the trademark.
