Mr. Dunkelman wrote BusBuddy, an app that takes GPS and scheduling data from OC Transpo, the local city bus service, and predicts when the bus you are waiting for will actually arrive. But when Dovden came along and asked for $10,000, as a "licensing" fee, Dunkelman got angry, and decided to fight. He hired an ace intellectual property and started chipping away at the company's claims...very successfully! And it went so good that Dovden has discontinued the suit, probably for fear of having a precedent established against them, and are now being chased by Dunkelman and his lawyer for legal costs. But Dovden has worse problems...the Canadian Urban Transit Association, representing transit agencies national wide, has filed suit to have Dovden's patents declared invalid!
