September 17, 2012- On September 13, 2012, the USPTO recorded the assignment of 14 issued US patents and five pending US applications from Tramontane IP (an IPNav enforcement entity) to an entity called ActiveGPS. RPX anticipates that IPNav will likely launch a new litigation campaign in the near future, likely against automotive companies, as the patents generally relate to navigation systems.  The assigned patents were sold by Delphi in 2011.  To date, IPNav has asserted patents from Delphi in three campaigns as SmartAudio, Cathas, and Tramontane.
