In its most recent patent-infringement complaint filed with the US International Trade Commission, the Finnish mobile phone maker Nokia Corp has accused Apple Inc of infringing seven of Nokia's patents associated with user-interface, camera, antenna and power-management technologies.

Seeking an order for the prohibiting Apple from importing the patent-violating products into the US, Nokia said in its complaint that "Apple infringes Nokia patents in virtually all of its mobile phones, portable music players and computers."

As per the Nokia complaint, the 'imported' electronic devices include Apple's smartphones - iPhone, iPhone 3G, iPhone 3G; its portable music players - iPod Touch, iPod Nano, iPod Classic; and its computers - iMac, Mac Pro, Mac Mini, MacBook MacBook Pro, and MacBook Air.

Elaborating on the Nokia complaint, Paul Melin, Nokia's general manager for patent licensing, specified that since Nokia happens to be the foremost developer for many crucial technologies used in small electronic devices, the filing of the lawsuit against Apple is part of the company's endeavors to protect the results of its "pioneering" developments.

Earlier too, Nokia has sued Apple in October alleging that the iPhone maker had violated 10 of Nokia's patents. While Nokia was sought back royalties on the 33.7 million iPhones sold since the
2007-launch of the device, Apple countersued Nokia in December, accusing Nokia of infringing 13 of its patents.
