A German court rules that Samsung Electronics's Galaxy Tab cannot be sold in Germany because it violated patents of rival Apple's iPad2.

A Duesseldorf state court said Friday it would not allow Samsung, based in Seoul, South Korea, to market its Galaxy Tab 10.1 in Germany because it too closely resembles the iPad2.

Already in August, the court had ruled in favor of Apple, based in Cupertino, California, forcing Samsung to withdraw its tablet from the market.

Samsung challenged the ban. The companies are involved in a series of legal disputes in countries around the world over allegations that each copies the other's technology.
