Samsung and Apple have been fighting a patent battle for a long time now that spans multiple products from both companies. Not long ago Samsung added a new Apple product to its patent infringement suit with the addition of the iPad mini. Apple is now adding a new Samsung devices to its patent infringement suit.
Apple filed documents with the US District Court for the Northern District of California adding six new Samsung products to its patent infringement suit. The new products include the Samsung Galaxy S III, Galaxy Note II, Galaxy Tab 8.9 WiFi, Galaxy Tab 2 10.1, Rugby Pro, and the Galaxy S III Mini. Samsung doesn't currently offer the S III mini in the US, but court documents show that Apple claims the device is available in the US through unofficial channels.
Apple added the new products to the patent infringement suit it filed in February of 2012 claiming Samsung violated several Apple patents. The patents that Apple alleges Samsung has violated have to do with user interface technology and product design. This year has been big for patent fights between Apple and several companies.
However, the largest patent battle that has resulted in a win for Apple came against Samsung when courts awarded Apple over $1 billion in damages. Samsung is trying to beat that $1 billion ruling in part by alleging juror misconduct in the case. Apple has indicated that it is adding new Samsung products to its case because the new products involve the same patents at the core of the original suit.
