A set of product placement ads for Microsofts Bing ran during NBCs The Philanthropist.

The ads showed two of the characters from the actual show in scenes in which Bing was being used clearly ads, but still integrated with the actual program. Not a bad idea right? Well, that depends on who you ask, because Microsofts ad agency JWT and its parent WPP are being sued over the ad. According to AdAge, a Delaware firm called Denizen claims to have patented this, and alleges that the agency has infriged upon it.
