In the new claim, Motorola Mobility asserts that Apple has infringed seven of its patents, a Motorola official confirmed Saturday. Motorola Mobility is asking the ITC to prohibit imports of iPhones, iPads and iPods that allegedly infringe those patents, which are not standards-essential, according to the official.

The documents citing the specific patents are not yet available from the ITC. Motorola Mobility issued a media statement Friday saying it had filed the new complaint with the ITC.

We would like to settle these patent matters, but Apples unwillingness to work out a license leaves us little choice but to defend ourselves and our engineers innovations," the emailed statement said.

Apple officials were not immediately available to comment.

The announcement of the new claim comes a week before the ITC is due to issue a final ruling on an earlier case. In April, an ITC judge said in a preliminary ruling that Apple infringed on a patent for eliminating noise. However, that claim is for a standards-essential patent. So-called standards-essential patents cover functions that are part of industry standard technology. Lawsuits related to such patents have created controversy in the tech market and legal circles, because these patents are expected by standards bodies to be licensed under so-called fair, reasonable and nondiscriminatory (FRAND) terms.
