Seattle artist Juli Adams is suing pet products company Hartz, alleging that the company denied her profits when it ditched her trademarked "Angry Birds" toy line in favor of licensed products based on Rovio's Angry Birds. Adams' catnip-filled toys predates Rovio's products, originally launching in partnership with Hartz in November 2006. Hartz received limited licensing rights. After the Angry Birds game debuted in 2009, Hartz began distributing Rovio-licensed toys. But its partnership with Adams was still in effect. Rovio is not targeted in the suit.
