laura sydell is covering this story for npr, and jns me now. what is it exactly that apple says samsung did, laura? a copy? a theft? a lift? what do they say happened? >> well, it comes down to a few patents actually. so, for example, if you look at the shape of the i-phone which we're all familiar with now. you have the nice glass face. you have this rectangular shape with rounded corners. apple says they patented that design. and that if you look at samsung phones before the i-phone came out in 2007, th had keyboards. they had sharp square edges and that as soon as the i-phone came out, they changed the design. so they were copying apple. now samsung is countering that, in fact, they did make phones like that. they just weren't as popular. while apple can show you patents that it has for these sorts of things, the patent office actually isn't always right. sometimes they grant patents that they shouldn't have granted. i think you're going to see samsung making that case in court over the next month. >> suarez: each company is demanding billion
