Apple has lost its appeal against a UK ruling that says Samsung did not copy its tablet designs.
A judge at the High Court in London upheld a ruling made in July that stated Samsung did not infringe Apple's iPad tablet designs, reports Reuters.
The court also ordered Apple to run adverts saying Samsung had not infringed its rights.
The US tech giant will now need to run ads on its website and in major publications such as the Daily Mail to "correct the damaging impression" that Samsung was a copycat.
Samsung is delighted with the ruling, saying in a statement that Apple's designs were never original.
"We continue to believe that Apple was not the first to design a tablet with a rectangular shape and rounded corners and that the origins of Apple's registered design features can be found in numerous examples of prior art," said the Korean firm.
"Should Apple continue to make excessive legal claims in other countries based on such generic designs, innovation in the industry could be harmed and consumer choice unduly limited", the company added.
The patent war between Apple and Samsung has hit the headlines in recent years due to increasingly embittered lawsuits across the world.
It reached tipping point this year when a jury in the US found Samsung had improperly violated patented technology in the iPhone and iPad and awarded Apple $1.05 billion (£653 million) in damages.
Meanwhile, in August a South Korean court ruled that Apple and Samsung infringed on each other's patents, and ordered the companies to stop selling some of their products in South Korea and pay damages. Apple was ordered to stop selling the iPhone 3GS, iPhone 4, iPad 1 and iPad 2.
