Apple has lost its copyright court appeal against Samsung after a judge ruled the Korean tech giant's Galaxy tablet was not as "cool" as the iPad.

The American electronics market leader argued that the Samsung Galaxy Tab was too similar to its own product.

However, Judge Colin Birss QC ruled at the High Court in London in July that the Galaxy tablet was not "cool" enough to be confused with Apple's iPad.

Apple later challenged the finding at the Court of Appeal.

On Thursday, Lord Justice Longmore, Lord Justice Kitchin and Sir Robin Jacob upheld Judge Birss' decision that three Samsung Galaxy tablet computers did not infringe Apple's registered design.

Judge Birss said earlier this year: "They do not have the same understated and extreme simplicity which is possessed by the Apple design. They are not as cool."

He said consumers were not likely to get the two tablet computers mixed up.
