Motorola Mobility has filed a new patent infringement complaint against Apple with the US International Trade Commission (ITC), according to reports. The Wall Street Journal said seven non-standard-essential patents are being asserted by Motorola.

The patents are linked to features including Apple’s Siri voice recognition technology, location reminders, email notification and phone and video players, according to Bloomberg. Motorola is understood to be attempting to secure a US import ban for iPhones, iPads and Mac computers, which are manufactured in Asia.

In an emailed statement made to Bloomberg, Motorola said that Apple’s unwillingness to licence the technology leaves “little choice but to defend ourselves and our engineers’ innovations."

The two companies have been at loggerheads since technology licensing talks failed in 2010. Apple has previously said Motorola is making unreasonable demands and that Android phones made by Motorola and other vendors copy key iPhone features.

Motorola already had a patent complaint against Apple lodged with the ITC, with the Commission expected to announce a decision – potentially an import ban – on 24 August. ITC judge Thomas Pender said in April that Apple infringed one of the four Motorola patents cited in that complaint.

Apple has also accused Motorola of infringing its patents with the Droid range of smartphones and the Xoom tablet. However, the lawsuit was dismissed by a federal judge Richard Posner in June after he rejected the damages claims of both sides.

Apple’s IP battle with Samsung meanwhile, is currently at its height with a trial taking place in California. The federal court case has now gone to the jury for a verdict.
