On May 4, 2018, Unified filed a petition for inter partes review (IPR) against U.S. Patent 6,178,380 owned and asserted by Beacon Navigation, GmbH, a well-known NPE. The '380 patent claims a "vehicle location display of a navigation system" that provides a navigation display that includes a first map with a first scale and a second map with a different scale. This patent has been asserted in 33 district court litigations against various automotive companies such as Toyota, Suzuki, Volvo, Nissan, Daimler AG, Hyundai, and Honda.
