The case is one of two patent infringement lawsuits pending in the US District Court in San Jose by Apple against Samsung. An earlier lawsuit by Apple that related to different patents resulted in a $1.05 billion jury verdict against Samsung on Aug 24.

Apple is also seeking to add the Samsung Galaxy S III, running the new Android "Jelly Bean" operating system, the Samsung Galaxy Tab 8.9 Wifi, the Samsung Galaxy Tab 2 10.1, the Samsung Rugby Pro, and the Samsung Galaxy S III Mini, to its lawsuit, according to a court filing on Friday.

"Apple has acted quickly and diligently to determine that these newly-released products do infringe many of the same claims already asserted by Apple," the company said in the filing.

Samsung representatives did not immediately respond to requests for comment.

Apple filed the second lawsuit in February, alleging that various Samsung smartphone and tablet products including the Galaxy Nexus infringed eight of its patents.

Samsung denied infringement and filed a cross-complaint alleging that Apple's iPhone and iPad infringed eight of its patents.

A US judge on Nov 15 allowed Samsung to pursue claims the iPhone5 also infringes its patents.
