US election 2012: Newt Gingrich faces lawsuit for using 'Eye of the Tiger' The law suit, lodged in a federal court by Rude Music Inc, a music company owned by Mr Sullivan, cites copyright infringement by Gingrich as far back as 2009. In addition to Mr Gingrich, the complaint names his campaign, Newt 2012 Inc, and the American Conservative Union, an advocacy organisation, as defendants. The complaint states that the alleged violation is intentional because Mr Gingrich is "sophisticated and knowledgeable" concerning copyright laws. In the five-page court document, it notes that Mr Gingrich's criticism of the Stop Online Piracy Act during a debate in South Carolina, demonstrated his knowledge of copyright laws. During the campaign he said: "We have a patent office, we have copyright law. If a company finds it has genuinely been infringed upon, it has the right to sue. Rude Music Inc has requested an end to unauthorised use of the song by the Gingrich campaign, and that Rude Music Inc is awarded damages for the infringement. A Gingrich campaign spokesman could not immediately be reached for comment.
