The German Federal Patent Court ruled today that Qualcomm’s GSM patent case against Nokia (NYSE: NOK) is invalid, Reuters reports. This is the third court to conclude that the American chipmaker’s patent claims against Nokia are “without merit,” said the Finnish handset maker. The United Kingdom High Court, and the U.S. International Trade Commission have also ruled that Qualcomm’s GSM patent claims against Nokia to be invalid. The two will meet again in German court in October, when a second Qualcomm (NSDQ: QCOM) patent case will be heard. The news comes on the same day that Qualcomm and Nokia are to meet in a Deleware Court over its ongoing patent dispute.
