Rockstar Consortium Inc., originally named Rockstar Bidco,[1] is a consortium formed to negotiate licensing for patents acquired from the bankrupt multinational telecommunications and data networking equipment manufacturer Nortel.[2][3] Members of the consortium are Apple Inc., BlackBerry, Ericsson, Microsoft, and Sony.[4] Rockstar is a patent holding non-practicing entity (NPE) and submitted the winning US$4.5 billion bid for the Nortel patents at a week-long auction held in New York in June 2011.[5]
Spherix Incorporated, a company founded by Gilbert Levin, has acquired four families of mobile communication patents from the Rockstar Consortium in exchange for initial consideration of up-front cash and Spherix common stock.[6] Rockstar will also receive a percentage of future profits from Spherix after recovery of patent monetization costs and an initial priority return on investment to Spherix.
In 2012, Business Insider listed Rockstar as number 3 on its list of the 8 most fearsome patent trolls in industry.[7] Wired magazine notes that some call them a "straight-up patent troll".[8]
