Nokia, the world's largest maker of cell phones, is suing Apple in U.S. federal court, saying the iPhone uses patented wireless technologies.
Nokia Corp. claims the iPhone infringes on ten patents covering both phone calls and Wi-Fi access. It says 40 other phone manufacturers have licensed these patents from Nokia, but Apple hasn't.
Apple Inc. didn't immediately respond to a message seeking comment Thursday.
Companies that develop cell phone technology regularly sue each other over patents. The usual outcome is that the defendant agrees to pay licensing fees, or the parties agree to share each other's patents.
The suit was filed in U.S. District Court in Wilmington, Delaware.
