Patent violation claims by Samsung Electronics against Apple have been unexpectedly dismissed from a South Korean court.
Samsung had been calling for a sales ban on a number of Apple products in South Korea - including the iPhone 4S, iPhone 5 and iPad 2 - based on three patent infringement allegations that these products were using Samsung's mobile messaging technology.
"We are disappointed by the court's decision," Samsung said in a statement. "As Apple has continued to infringe our patented mobile technologies, we will continue to take the measures necessary to protect our intellectual property rights."
As well as the rejection of the sales ban, the court also dismissed Samsung's claim for 100 million won (£58,000) in damages.
A spokesperson for Apple Korea said: "We are glad the Korean court joined others around the world in standing up for real innovation and rejecting Samsung's ridiculous claims."
The loss at Seoul Central District Court today is the latest setback for the South Korean firm in a long-running series of patent disputes with Apple.
In November Samsung was ordered to pay Apple $290 million (£179 million) by a California jury for damages relating to patent infringements by a number of Samsung devices, including the Galaxy Prevail and Galaxy SII.
The decision came just a few months after Apple won a similar patent-infringement case to the one in the Korean capital this week, resulting in the ban of certain Samsung products being imported to the US.
