The developer only has the one game - Candy Crush Saga - with the word "candy" in the title, but it has seven different games that include the word "saga", including Farm Heroes Saga, Pet Rescue Saga, and Papa Pear Saga. And, as part of its process, King has already filed a legal challenge to The Banner Saga, which is an RPG from developer Stoic. Not only does The Banner Saga not have any similarities to any King properties, but The Banner Saga is only available for PC and Mac, and is not available on mobile platforms (or through Facebook, where King lives).
A King spokesman told Kotaku that this legal action is not designed to stop The Banner Saga from using the name, but to essentially set a precedent for future cases:
Of course, aside from the trademark issues, it seems that no one has pointed out to King that literally all of its games are clones of other popular titles. Candy Crush Saga is a modified version of Bejeweled and dozens of other matching games, Papa Pear Saga is a clone of Peggle, and Bubble Witch Saga has roots going back to the 90s with Puzzle Bobble and Snood. But, it's obviously bad to cause confusion with a name, right? Next, King will likely go after any product that refers to "Star Wars: The Complete Saga".
