iPhone cut, copy, paste - more on patent problems

I speculated that iPhone cut, copy, paste was missing due to patent problems. A commenter added:

A buddy of mine used to work for MS Mobile division and when I started using the Blackjack he kindly gave me I complained about there being no cut copy paste in smartphone addition of windowdose mobile. His simple reply was 'patent issue'.

Well, it does make sense.

So are patents also the problem with tasks on the iPhone?
