Candy Crush Saga, Papa Pear Saga, Bubble Witch Saga, Fruit Heroes Saga are all pretty huge games. It's clear that Saga is part of King's brand. Games will come out and try to use that same name style to reap the benefits. Jewel Blitz Saga can come out from some random developer and people will download it thinking it is King's because it's the same branding. Not saying Banner Saga is doing this at all, but if they ignore them, then the trademark is pretty much invalid because any other developer will come in and say "they let those guys go, so they can't go after us either" and then trademark patents are useless. This trademark only applies to online games.
