Samsung has bulked up its legal case against Apple in Germany after it filed claims over four new patents today, that’s following the initial telecom standards-based charges that were filed in April this year.

A company spokesperson informed Reuters of the four new complaints added by the Korean manufacturer, one of which relates to the use of emoticon, stating:

(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.

The new charges follow Friday’s decision from a regional German court which confirmed that a final decision on the case will be made on March 2.

The two companies have sparred in court rooms across a number of countries through legal cases relating to Samsung’s Galaxy range and Apple’s iPhone and iPad devices.

Back in September, Apple was successful in an attempt to introduce a sales ban for the Galaxy Tab 10.1. Following the ruling, Samsung appealed and re-modified its product, introducing the Galaxy Tab 10.1N, in order avoid the infringements and gain clearance for sale in Germany.

Samsung recently scored a high profile victory in Australia where a ban on the Galaxy tablet was overturned last month, allowing the manufacturer to begin introducing the product in time for the Christmas shopping season.

Samsung u-turned on its intention to try to block sales of the iPhone 4S in its native South Korea, during November, after statements from the firm suggested that it did not want its legal battles with Apple to reflect badly on home turf.

The ongoing global legal spat between the duo took a significant turn with the news that the European Commission, the legislative body of the European Union, is investigating Samsung for a possible abuse of FRAND licensing. The outcome has the potential to force the Korean firm to drop its litigation cases in Europe.

Elsewhere in Europe, Samsung previously saw a sales ban fail in Holland, the country where it was forced to modify three of its Galaxy smartphones for sale after the models were adjudged to have infringed on patents held by Apple.

Other spats continue in the US — where Apple designers will soon begin testifying— and in Italy, as the two mobile giants continue to lock horns over the use of mobile technology patents in their respective smartphones.
