Who hasn't heard of Apple's win over Samsung in a bitter property intellectual fight? Probably, no one, or if there are still others who haven't, they probably have not even heard of mobile phones either.
According to Reuters, Tim Cook, Apple's present CEO never wanted to sue the Korean tech company over design issues the reason for this being Samsung was the supplier of some of the most important elements used in making iPads and iPhones.
So what made Apple sue despite Samsung being their major supplier of parts and technology and them being a major client of the other? Pulling each other down would only mean big losses in profits for both.
One reason why is to possibly pressure the Korean giant to affirm their allegiance with Google, despite their other commitments to non-Android OS's. Somehow, suing Samsung makes Apple hit two birds with one stone: to go to court against Google (their relevant rival) indirectly and to pressure Samsung over the extent of their "duty" to Android.
