Samsung has added a further four patents to its infringement case against Apple in Germany.

Samsung Electronics has filed four new patent claims in its ongoing infringement case against Apple in Germany, according to Reuters.

The case is related to the telecommunications standard technology WCDMA for 3G mobile handsets and was filed in April.

The four new complaints include the use of emoticons and come as the worldwide patent battle between Apple and rival Samsung continues to escalate.

"[Samsung] made four more claims; two are standard-related patents and the other two are utility patents. And a court said it would make these claims separate from the April lawsuit," a Samsung spokesman told Reuters.

A regional German court in Mannheim held a hearing on the April case, saying it would announce a ruling on 2nd March.

Samsung won one round of its global battle against Apple, when an Australian court lifted a ban on the sale of its Galaxy table computer earlier in December.
