The world’s largest mobile-phone seller has added claims about the iPhone 5 to an existing patent-infringement lawsuit between the two companies.
In its court filing, Samsung said: “As soon as the iPhone 5 was available for purchase, Samsung began its investigation of the product.
The company claims that the iPhone 5 infringes two standards patents and six features patents.
The case is scheduled for trial in 2014 and includes all the previous iPhones as well as the iPad tablets and the iPod Touch.
The two firms have been at loggerheads over design and technology patents and are fighting legal battles on four continents.
In a separate patent case in August, Apple won a $1.05 billion jury verdict against Samsung. However, Apple is now demanding more while Samsung says the jury verdict is invalid. An appeal hearing is scheduled for December, so the saga is far from over.
Rumour that both companies will settle their differences by building giant robots that will battle to the death in a post-industrial wasteland are unfounded.
