Samsung Electronics Co. said Wednesday that it has asked a European Union (EU) agency to invalidate the iPad\'s design rights in Europe, as the world\'s No. 2 mobile phone maker seeks to resume sales of its tablet computers in the pivotal market. Samsung filed an application with the Office for Harmonization in the Internal Market (OHIM) on Aug. 9 to nullify Apple Inc.\'s exclusive rights to the iPad\'s design, a company spokesman said, confirming an earlier report by the Donga Ilbo, a Seoul-based daily newspaper.
