Ubisoft is being sued by author John L Beiswenger, who claims the Assassin’s Creed franchise has a lot of similarities to his book, Link.
Link was published in 2003 and explores the possibility of accessing memories of people’s ancestors through science. These memories can also be relived. You’ll notice that this is what Desmond is doing through the Assassin’s Creed franchise. Link also makes some references to assassinations, as well as religious and spiritual themes.
Beiswenger is suing Ubisoft for a minimum of $1.05 million, though this could rise to $5.25 million if the ruling judge believes that Ubisoft did infringe the copyright. Beiswenger also wants Assassin’s Creed III and other future related franchise merchandise to be prevented from being sold.
