As confirmed by Nokia, the giant manufacturer of mobile handsets, it has filed a complaint with the U. S. International Trade Commission, taking the lawsuit which alleges that Apple Inc., the maker of the grand iPhone, infringed as many as 7 of the firm's patents, to a new level. Nokia also filed a similar lawsuit over the same patents in a Delaware federal court today.

In the ITC complaint, Nokia, which is the world's largest mobile handsets manufacturers, has stressed that Apple has infringed "virtually all" of its mobile phones, music players and computers. Also, it has been alleged that Apple has used infringed technology for its iPhone, iPod and MacBooks.

Nokia is now seeking an order which would exclude Apple from importing the "infringed" products into American.

"Nokia has been the leading developer of many key technologies in small electronic devices. This action is about protecting the results of such pioneering development", said Paul Melin, Nokia’s General Manager for Patent Licensing.

In October, Nokia had sued California based Apple over infringement of 10 patents, and the lawsuit demanded royalties on the 33.7 million iPhones sold worldwide since the device was launched in 2007. Apple, on its end, countersued, claiming the Nokia had, infact, infringed 13 of Apple's patents.

No comments on the development have been shared by Apple yet.
