Apple Inc. has filed a patent lawsuit in South Korea, claiming Samsung Electronics Co. Ltd. infringed upon several patents, a court official said on Friday, in their latest legal tussle over smartphone and tablet devices.
The litigation comes as Samsung filed patent suits in South Korea, Japan and Germany in April over the U.S. company's iPhone and iPad after Apple claimed Samsung's Galaxy line "slavishly" copied its products.
