Did Apple claim that? If so that was wrong of them (and weird, given Steve Jobs publicly condoned "stealing" tech ideas). As for actually copying a technology (paying relevant fees of course), that fine, that's a good thing. I'm glad Exposé is finally coming to Windows 10, for example. That's a very different thing from ripping off other people's aesthetic designs, effectively copying their art style. Actually, that's not the best way of putting it - in art taking inspiration from somebody else's work and doing your own thing with it is perfectly valid, but this is more like coping their work paint stroke by paint stroke, chord by chord.
Watch the video, Steve Jobs clearly says:
We have invented a new technology called multitouch.... and boy have we patented it.
