THE group that owns thousands of former Nortel patents filed a barrage of patent lawsuits on Thursday against cell phone manufacturers including Google, the company it outbid in the Nortel bankruptcy auction.
Rockstar, the consortium that bought the Nortel patents for $4.5bn, sued Samsung Electronics Co Ltd, HTC Corp, Huawei and four other companies for patent infringement in U.S. District Court in Texas. Rockstar is jointly owned by Apple, Microsoft, Blackberry, Ericsson and Sony.
Google is accused of infringing seven patents. The patents cover technology that helps match Internet search terms with relevant advertising, the lawsuit said, which is the core of Google's search business.
Samsung, Huawei and HTC all manufacture phones that operate on Google's Android operating system, which competes fiercely with Apple and Microsoft mobile products.
In 2011 Google placed an initial $900m bid for Nortel's patents. Google increased its bid several times, ultimately offering as much as $4.4bn.
"Despite losing in its attempt to acquire the patents-in-suit at auction, Google has infringed and continues to infringe," the lawsuit said.
Rockstar is seeking increased damages against Google, as it claims Google's patent infringement is willful, according to the complaint.
