The two phone giants are in the midst of a major legal battle, which started last October when Nokia charged Apple for using its patented technologies without paying for them. Apple filed the new ITC complaint on Friday.

"Nokia will study the complaint when it is received and continue to defend itself vigorously," said a company spokesman.

"However, this does not alter the fact that Apple has failed to agree appropriate terms for using Nokia technology and has been seeking a free ride on Nokia's innovation since it shipped the first iPhone in 2007," he said.

In late December Nokia also filed a claim with the ITC, alleging Apple infringed seven of its patents in "virtually all of its mobile phones, portable music players, and computers" sold.
