Apple sues Samsung for 'copying' iPhones and iPad
Apple is suing its rival Samsung Electronics for allegedly copying the design of its iPad and iPhone.
It claims Samsung's Galaxy range of mobile phones and tablet "slavishly" copy the iPhone and iPad, according to court papers.
Apple's claims focus on Galaxy's design features, such as the look of its screen icons.
Samsung said it had conducted its own research and development and would contest the allegations.
Galaxy products use Google's Android operating system, which directly competes with Apple's mobile software.
As well as being a competitor, Samsung supplies Apple with microchips that are used in some Apple products, such as the A4 and A5 processors, as well as memory chips used in MacBook Pro computers.
