Samsung has suffered its second patent loss against Apple in as many weeks. The company has said that a German court has ruled that its second of three patent claims related to 3G/UMTS has been rejected. The latest blow in its bitter ongoing legal battle with Apple comes after the same court ruled that the first of the three patents that it is asserting against Apple was also rejected. The Mannheim court has reserved its decision on the third of SamsungĂs 3G claims until March 2.
