Google's Motorola Mobility division has filed a patent infringement claim against Apple over the Siri voice control and location-based services used on iPhones and iPads.
According to Bloomberg, Google's Motorola Mobility unit filed a complaint against Apple with the US International Trade Commission (ITC) on Friday.
Motorola is reportedly claiming that Apple devices, including the iPhone and iPad, infringe seven of its patents, including location reminders, email notifications, video players and Apple's Siri voice assistant feature.
Motorola is seeking a ban on US imports of devices including the iPhone, iPad and Mac computers. If this complaint is successful, it looks like the Motorola acquisition might pay off for Google after all.
"We would like to settle these patent matters, but Apple's unwillingness to work out a licence leaves us little choice but to defend ourselves and our engineers' innovations," said a Motorola spokesperson.
This is not the first time that Motorola has filed a patent infringement lawsuit against Apple. The two companies have been at odds since licensing talks failed in 2010.
Most recently, US Court of Appeals judge Richard Posner dismissed patent infringement claims from both Apple and Motorola in the US District Court, and the ITC is due to make a decision on 24 August as to whether Apple infringes on a Motorola Wi-Fi patent.
The Motorola action is just one of a long line of lawsuits involving Apple. Apple is still embroiled in ongoing legal action with Samsung, with both firms suing each other over patent infringement claims.
Apple was unavailable for comment at the time of publication.
