The group that owns thousands of former Nortel Networks patents filed a barrage of patent lawsuits on Thursday against mobile-phone manufacturers including Google, the company it outbid in the Nortel bankruptcy auction.

Rockstar is jointly owned by Apple, Microsoft, BlackBerry, Ericsson and Sony.
Google is accused of infringing seven patents. They covered technology that helped match internet search terms with relevant advertising, the lawsuit said, which was the core of Google's search business.
A Google spokesman declined to comment. Representatives for Samsung, Huawei, HTC and Rockstar could not be reached.
Samsung, Huawei and HTC all manufacture phones that operate on Google's Android operating system, which competes with Apple and Microsoft mobile products.
