The Rockstar consortium is an organization backed by Apple, Microsoft, BlackBerry, Ericsson and Sony. It purchased patents off of the defunct telecommunications company Nortel in 2011, in a bidding war with Google.
Now, the consortium has filed suit against Google, ASUSTek, HTC, Huawei, LG, Pantech and ZTE over those patents. The suit was filed in a U.S.
A consortium of Apple, EMC, Ericsson, Microsoft, Research In Motion and Sony has beaten Google to pay $US4.5 billion for more than 6,000 Nortel patents and patent applications spanning wireless, wireless 4G, data networking, optical, voice, internet, service provider, semiconductors and other patents.
