Samsung has what it hopes will be ace up its sleeve: At least one iPhone-like device, eventually released as the F700, was registered in South Korea prior to the iPhone's debut, according to Samsung's trial brief.
The F700, announced in February 2007 -- one month after Jobs' iPhone reveal -- has a large touchscreen and a slide-out keypad. It ran a proprietary Samsung operating system called Croix.
Apple originally included the F700 in its copying allegations, but later dropped the model from its complaint after Samsung established its prior, independent creation, Samsung said in its court documents.
Apple is asking for billions from Samsung, but the case is unlikely to reshape the smartphone landscape.
