Samsung said the claims, filed on December 16 with the Mannheim regional court, relate to alleged infringement of patents including those for Samsung’s telecommunications standard technology and user interface.
The two technology giants are engaged in a legal battle involving dozens of cases worldwide as they struggle for leadership in the hugely lucrative smartphone and tablet computer market.
Apple began the process in April, accusing Samsung of “slavishly” copying its iPhone and iPad designs. Samsung has focused its own lawsuits on technology patents rather than design.
The South Korean giant has received two legal boosts this month.
On December 9 Australia’s High Court cleared the way for Samsung to sell its Galaxy 10.1 tablet in the country in time for Christmas, dismissing Apple’s bid to have a ban extended.
Earlier in the month a federal court judge in San Jose, California, denied Apple’s request for a preliminary injunction that would have banned the sale of three Samsung smartphones and a tablet computer in the US.
