Apple filed a lawsuit against Samsung Electronics. Friday, accusing the South Koran company of infringing its patented technologies used in making the iPhone. Apple's complaint was filed with the Seoul Central District Court. The company requests Samsung to stop selling a line of its new Galaxy touch screen smartphones and the Galaxy Tab tablet PC , as both products "look a lot like the iPhone and iPad, from the shape of the hardware to the user interface and even the packaging."

Apple also argues that both Samsung's devices infringe its patented technologies used in the iPhone, which enable users to scroll up and down a long electronic document by flicking the touchscreen.

Apple also demanded 100 million won (US$92,500) in compensation.

Apple had filed similar lawsuits against Samsung in the U.S. in April.

Samsung Electronics had countered by filing similar lawsuits against Apple in the U.S., South Korea, Japan and Germany, arguing that the U.S. firm has copied 10 of its patents to make the iPhone.

However, despite their competition in mobile products, the two firms have a close business relationship. Apple was Samsung's second-largest client in 2010 after Sony, accounting for four percent of the South Korean firm's annual revenue.
