Apple today added a twist to the legal battle between the company and Nokia. In October Nokia accused Apple of "trying to get a free ride on the back of Nokia's innovation". Nokia stated that Apple infringes on 10 Nokia owned patents in the iPhone.
In a turn of events Apple is now countersuing Nokia claiming that the worlds largest mobile phone maker is infringing on 13 of Apple's technology patents. "Other companies must compete with us by inventing their own technologies, not just by stealing ours," Apple said.
Apple has yet to reveal which patents are in question.
