(AP) -- South Korea's Samsung Electronics Co. says it sued Apple Inc. for patent rights violations, only days after Apple sued Samsung for the same reason.
Samsung is accusing Apple of violating its rights to 10 smartphone and computer patents. The company filed lawsuits Thursday in Seoul, Tokyo and Mannheim, Germany.
The lawsuits come only days after Apple sued Samsung in a California court. Apple alleges Samsung's Galaxy line of smartphones and tablet computers copy Apple's popular iPad and iPhone.
The lawsuits are the latest in a long string of patent disputes among phone makers. In recent years Apple, Microsoft Corp., Nokia Corp., HTC Corp. and others have taken legal action to protect their intellectual property rights.
