Looks like Nokia is going all-out in its patent fight with Apple: in addition to the lawsuit it’s filed over GSM standards and last week’s International Trade Commission complaint , Espoo just filed a second complaint with the federal court, alleging that Apple’s infringing several “implementation patents” that cover everything from camera sensors to touchscreens. That’s three fronts in the same war, if you’re counting — the original regarding GSM patents , and these two latest over specific device technologies.
