Rebellion Developments (Rogue Warrior, Aliens vs Predator, Sniper Elite) is suing Stardock Entertainment and Ironclad Games in an Eastern Michigan district court for trademark violation over the use of the word "rebellion" in the title of Sins of a Solar Empire: Rebellion. Rebellion is asking for damages for being "deprived of substantial sales of its products" and for "the value of its trademarks as commercial assets." GameSpot notes: "Rebellion provided several examples where it claimed consumers would have been easily misled, including promotional materials which displayed the word 'Rebellion' much larger than the preceding 'Sins of a Solar Empire' and some that referred to the game only by the disputed trademark."
