Nokia sues Apple over iPhone

Nokia, the world's biggest cellphone manufacturer, has said that it is suing Apple for infringing patents on technology used in the iPhone.

The ten alleged patent infringements involve wireless data, speech coding, security and encryption. Nokia claims the infringements apply to all iPhones sold so far.

The specific allegations raised in the lawsuit concern patents relating to three areas of wireless technology.

• GSM
• 3G (UMTS or W-CDMA
• An unnamed wireless local area network (LAN) technology, most likely WiFi.

Nokia claims that Apple is "trying to get a free ride on the back of Nokia's innovation."

There's speculation that Nokia could grab as much as $12 per iPhone sold.

Apple's shares fell following news of the legal action.
