As per usual with IP law, this thread is filled with incorrect information. King is not currently suing the makers of The Banner Saga. They're just objecting the the trademark.
This is not an example of a bad trademark system. King does not currently have a trademark on "candy" or "saga". Their request for a trademark on "Candy" has made it through the first hoop, but it will be challenged and probably not go through. Their trademark for "saga" has already been suspended.
King is not being a troll here either. They actually have a real product that makes money that is being infringed on by companies making obvious clones or copying the name. It is not really surprising that they would object to the trademark of "Banner Saga", since that trademark could then possibly be used against them. Not having "Banner Saga" trademarked will not force that game to have its name changed or anything. Now, if King does get a mark on "Saga" they could then try to force a name change.
King's lawyers are definitely going overboard even trying to get marks on "Candy" and "Saga" though. I think the system will work though (ie, the marks will eventually fail).
