"Nokia has been the leading developer of many key technologies in small electronic devices" said Paul Melin, General Manager, Patent Licensing at Nokia. "This action is about protecting the results of such pioneering development. While our litigation in Delaware is about Apple's attempt to free-ride on the back of Nokia investment in wireless standards, the ITC case filed today is about Apple's practice of building its business on Nokia's proprietary innovation."
The ITC action is the latest step taken by Nokia to fight off fierce competition from Apple, with the inclusion of the U.S. firm's iconic iPod and iMac products in the complaint marking an escalation from previous patent claims.
Both firms had earlier this year launched patent infringement suits against the other.
In October Nokia said it had filed a lawsuit in the U.S. state of Delaware, accusing Apple of infringing 10 patents and trying to hitch a "free-ride" on Nokia's technology investments.
This month Apple struck back, saying Nokia infringed 13 of its patents and accusing the Finnish firm of anti-competitive practices. Nokia said the countersuit did not change anything fundamental in its own case.
