Two technology giants, Apple and Samsung, are taking their legal battle over claims of patent infringement before a jury in a court in California.
Apple is accusing the South Korean firm of copying its patented software and is seeking $2.5bn in damages. However Samsung denies the charge and has launched its own counterclaims.
As Michelle Fleury reports, the two companies have a complex relationship.
