Ravensburger is a German gaming company that specializes in jigsaw puzzles, but has also expanded into other areas such as children's books and games. The company owns the trademark to a board game called 'Memory' and has demanded Apple stop offering apps that have the word 'memory' in their title or as a keyword associated with an app. It may seem ludicrous such a common word can be trademarked, but apparently this is a valid claim as Apple is now serving notices to app developers. The choice an infringing app developer has is to either rename their app or remove it from the App Store.
