Apple's shares closed up 1.9 percent at $351.54. Nokia shares ended 0.3 percent lower at 5.97 euros before the decision was released.
Judge James Gildea, of the International Trade Commission, which hears many patent cases, said in his initial determination that Apple did not violate the Nokia patents. The complaint had been filed in December 2009.
The next step will be for the entire commission to either uphold or throw out Gildea's decision. The target date for that decision is August 1, 2011.

Apple's iPhone and devices running on Android have carved out a large chunk of the lucrative and quickly expanding smartphone market, in large at the expense of Nokia, which has stuck mainly to its old workhorse Symbian software.
In addition to the iPhone 3GS mobile phone and iPod, the complaint was also directed at other iPhones, the iPod Touch, and iPod Classic portable music players, as well as the iMac, Mac Mini, Mac Pro, Mac Book, MacBook Pro, and MacBook Air computers.
