The complaint is the second that Motorola Mobility has filed at the U.S. International Trade Commission against Cupertino, California-based Apple. A copy of the new complaint wasn't immediately available. The Washington-based commission is scheduled to announce a final decision Aug. 24 in the earlier case, and could impose an import ban on the iPhone.
"We would like to settle these patent matters, but Apple's unwillingness to work out a license leaves us little choice but to defend ourselves and our engineers' innovations," Libertyville, Illinois-based Motorola Mobility said in an e- mailed statement.
Apple had no comment.
The complaint claims Apple infringed on seven Motorola Mobility patents for features including location reminders, e-mail notification and phone/video players.
