Samsung Electronics Co Ltd on Thursday lost its bid to ban sales of Apple Incs older iPhone and iPad in South Korea, as a court dismissed a lawsuit claiming the U.S. firm had infringed three of Samsungs mobile patents. The lawsuit was part of the tech giants global courtroom battle dating back to 2011, when Apple first sued Samsung for copying the look and feel of its iconic iPhone and iPad. A judge at the Seoul Central District Court said Apple products such as the iPhone 4S, iPhone 5 and iPad2 did not violate Samsung patents on short message display methods and messaging grouping features. In a separate ruling in August last year, the same court ordered Apple to pay Samsung 40 million won in damages for infringing two of the South Korean firms wireless technology patents.
