Canada : Apple and Samsung are facing each other in a California court for a third trial involving the same set of five patents.
Apple was originally awarded $1.05bn (£772m) in 2012 after a jury found the South Korean firm had infringed several of the iPhone’s innovations.
That sum was reduced to about $400m after the first retrial and other legal efforts by the Galaxy smartphone-maker.
But a fresh hearing became necessary after a Supreme Court ruling on how the penalties were calculated.
Retrial judge Lucy Koh, who also sat in the first case, has said she intends to apply a “Groundhog Day” rule.
