Google and its mapping service Waze are being dragged to court over allegations that Waze stole data from a rival's map database. The lawsuit filed in San Francisco federal court on Tuesday by PhantomAlert alleges that the navigation app used proprietary data from PhantomAlert without permission. Both apps share road, red light and traffic information. According to PhantomAlert CEO Joseph Seyoum he noticed that Waze was using the same fictitious location information in its app that his company had used to test PhantomAlert. The only way Waze would have that fake location data is if it was using information from Seyoum's company.
