Ameranth [NPE] filed suit against ChowNow, alleging that ChowNow’s ordering systems infringes three patents related to online and mobile restaurant, food service, ticketing, and reservation systems.  Ameranth has filed over 10 prior suits since June 2007 against over 30 defendants and has been subject to two actions for declaratory judgment.  One of the patents-in-suit originated with AT&T.  Ameranth claims to be the owner by assignment of the patents-in-suit, but this has yet to be recorded at the USPTO database.  5/18, Southern District of California, Judge Dana M. Sabraw, 3:2012cv01201.
