What? You agree that nobody else can use the word 'candy' because they've made a successful game? That makes no sense. This means if you decided to launch a game called Zombie Candy or something they could go after you.
All I am saying is in my circle of family and friends any mention of the word candy leads to questions like "which level are you on in candy crush", "Oh that was such a difficult level", "wtf you haven't played candy crush yet??!!", etc. etc.
