Google's Motorola Mobility unit said it filed a new patent-infringement case against Apple claiming that features on some Apple devices infringe its patents.
The complaint at the U.S. International Trade Commission claims infringement of seven Motorola Mobility patents on features including location reminders, e-mail notification and phone/video players, Motorola Mobility said yesterday. The case seeks a ban on U.S. imports of devices including the iPhone, iPad and Mac computers. Apple's products are made in Asia.
Motorola Mobility said that Apple was not willing to work out a license.
Motorola Mobility and Apple have been fighting since 2010 after licensing talks failed. Apple has said Motorola Mobility is making unreasonable demands, and argues that phones made by Motorola Mobility and other handset manufacturers that run on Android operating system are copying key patented features of the iPhone.
The dispute is part of a broader battle for share in a smartphone market. Apple is in the midst of a patent-infringement trial in federal court in California with its biggest rival, Samsung Electronics.
A trade judge in April said Apple infringed one of four Motorola Mobility patents in the first case. The patent covers a way computers transmit signals through Wi-Fi.
