In 2011, Nortel sold its patent portfolio to Rockstar, a consortium of companies including Apple, Microsoft, Sony, Ericsson AB and EMC. According to The Star:
The purchase will give Apple and its five bidding partners control over more than 6,000 patents and applications that cover wireless and Internet technologies ranging from mobile standards to Internet search and social networking.
Do we know for certain which patents, and in particular which pending patents Rockstar acquired from Nortel?
