A judge in Japan has ruled that Samsung's smartphones and tablets do no not infringe on any of Apple's patents. The ruling runs counter to one made last week in a US court, which ordered Samsung to pay Apple $1.05 billion (£665m) in damages.

Apple had sued Samsung in Tokyo in 2011 seeking 100m Yen (£807,287.925) in damages alleging that Galaxy S, Galaxy II and Galaxy Tab infringed patents on synchronisation.

"It's hard to believe the products belong to the range of technologies of the claimant," said Tokyo District Judge Tamotsu Shoji. The court has ordered Apple to pay litigation costs.

Shares in Samsung rose after the verdict.
