Videogame maker King, creator of the Candy Crush Saga, a game that has millions of fans around the world, said on Tuesday it had trademarked the word “candy” to protect the game from persistent intellectual property infringements. Created in 2003, King has experienced an explosion in popularity since launching on Facebook in 2011 with its saga games, in which players move through a competitive landscape and pass their friends on the way. Candy Crush Saga was the top downloaded free app for 2013, and the year’s top revenue grossing app. The company now says it wants to protect its game title from imitators who also use the word “candy”.
