Nokia is suing smartphone rival Apple for alleged patent infringements in the continued struggle between the two for market share.
Nokia claims infringement of 10 patents dealing with core aspects of the three key wireless standards.
The patent infringement claim filed in a US Federal court indicates an intensification of tactical manoeuvring between Nokia and Apple, according to the Financial Times.
Nokia claims that failing to pay royalties has given Apple a competitive advantage because it can afford to charge less for its iPhone, according to the complaint filed in Delaware.
The Nokia complaint comes after its smartphone market share dropped 41% in the past three months and its mobile division recorded a 7% drop in third quarter operating margin compared with the same period last year.
But according to analysts, the fact that Nokia is not seeking to block Apple's sale of its iPhone means the court case may be aimed at opening negotiations with Apple to license its multi-touch technology.
