Apple and Samsung are at legal loggerheads in at least 10 countries around the world. In one court case, in Korea's Seoul Central District Court, where Samsung has brought a patent infringement case against Apple's mobile operating system, Samsung is putting pressure on Apple to show it the iOS 6 source code, according to The Korea Times. The paper reports Samsung is arguing that without seeing iOS 6, it can't judge whether Apple's software infringes its technology patents.
