Apple has lost its appeal against a UK ruling that Samsung had not copied the design of its iPad.
A judge at the High Court in London had originally ruled in July that Apple’s rights had not been infringed by the Galaxy Tab 10.
He said at the time that Samsung’s device was not as “cool” because it lacked the “extreme simplicity which is possessed by the Apple design”.
He also ordered Apple to run adverts saying that Samsung had not copied it.
Judge Birss said one notice should remain on Apple’s website for at least half a year while other ads should be placed in various magazines and newspapers to “correct the damaging impression” that Samsung was a copycat.
A spokeswoman for Samsung said it welcomed the latest ruling.
“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.
“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.”
Apple has not released a statement.
The California-based company has also lost lawsuits in the Netherlands, Australia and US in which it claimed that the South Korean company had copied the look of its tablet – despite sometimes winning temporary sales bans.
However, it has been more successful with other claims.
Most notably a US jury proposed Samsung should pay Apple a $1.05bn (£650m) fine for infringing several software patents, and the look and feel of the iPhone. Samsung is appealing the verdict.
