Patents again

IBM is suing Amazon over some patents it owns [AP]

What caught my eye was this line: "IBM is the world's leading patent holder, spending $6 billion a year in research and development and earning about $1 billion a year in royalties."

In other words even IBM with the worlds largest patent portfolio makes only a modest sum from each patent and does not recover its R&D costs from patent licensing alone.
