Apple takes on Nokia at trade commission

Steve Jobs made Apple's iPhone one of the best-selling smart phones on the market with its touch-screen, fast Web connection and access to more than 300,000 downloadable applications. Now he's adding lawyers to the mix.

Apple is squaring off this week against Nokia Oyj, the world's largest maker of mobile phones, before the International Trade Commission. The dispute, in which each side alleges intellectual property violations, is also a precursor to Apple patent battles with Motorola Inc. and HTC Corp. At stake is leadership in the U.S. smart phone market.
