(Telecompaper) The Rockstar consortium, which bought Nortel patents for USD 4.5 billion during the company's bankruptcy process, is suring Google, Samsung, Huawei, HTC, and three other company for patent infringements, Reuters reported. Rockstar, jointly owned by Apple, Microsoft, Blackberry, Ericsson and Sony, was able to outbid Google during the patent auction. Google is accused of infringing seven patents. The patents cover technology that helps match internet search terms with relevant advertising, the lawsuit said. A Google spokesman declined to comment. Representatives for Samsung, Huawei, HTC and Rockstar could not immediately be reached. Rockstar is seeking increased damages against Google, as it claims Google's patent infringement is willful, according to the complaint.
