What is the benefit that IBM gets from this access to the patents of others? It is basically the benefit of being excused from the trouble that the patent system can cause you. The patent system is like a lottery. What happens with any given patent could be nothing, could be a windfall for some patent holder or a disaster for everyone else. But IBM being so big, for them, it averages out. They get to measure the average harm and good of the patent system.
