Samsung files another suit against Apple in South Korea

Samsung Electronics Co. has filed another lawsuit againstApple Inc. in South Korea, as the epic patent wars between the two companies continue.

The latest suit, filed by Samsung in Seoul, asserts that the iPhone 4S and the iPad 2 infringed on three of Samsung’s patents relating to display data, user interface and short text messages, Reuters reports.

Samsung and Apple have been waging patent wars in the courts of 10 countries in more than 30 lawsuits, according to Reuters.

Apple was the first to throw down the gauntlet in April, when it alleged that Samsung “slavishly” copied its iPhone and iPad models.

Apple has won a temporary sales ban on Samsung’s Galaxy Tab 10.1 tablet in Germany and filed suits seeking a ban on sales of 10 Samsung smartphones as well.

Samsung’s track record hasn’t been nearly as good. While the company has been able to fend off many of Apple’s accusations, it has not been able to get any of its own allegations to stick.

Writing on the blog Foss Patents, intellectual property analyst Florian Mueller said it is essential for Samsung to succeed on some offensive accounts against Apple.

“Otherwise, other industry players would have doubts about the strength of Samsung’s patent portfolio,” he said.
