Microsoft and Apple are twins
It is not that odd now to see how Apple is similar to Microsoft in this and other affairs. Here is an algorithm that seems to apply to them now:
1) when you find yourselves floundering in a muddy stagnant proprietary puddle, being unable to innovate. When stealing doesn't help anymore , your competitors are better, sue them for rounded corners, circular squares, rounded wheels, rubber band, exFAT long names, double-clicks or any other rocket science patents you find suitable and suable.
2) when the competitors see this and ask to pay for their piece of cake technologies that, e.g., make cell phones cell phones, start a very audible whining noise "WTF, they make us, well known orphans, pay for our lunch, how dare they! Abuse of FRAND!!"
3) Do not attack your comrades-in-proprietary-arms, other respectable jackals of industry. Do help them with all means at your hands and in your pockets. Use pockets of others if necessary, may outstanding jury foremen and the Great American justice system help you. Microsoft, Apple, Oracle and all the like, unite! Commemorate the life and death of SCO!
