I didn't know that, but I'm happy that they too must have realised how outragous this patent is. If they're no longer sueing over it, why have it?
"Amazon has got a number of other menacing patents since then, but has not as yet used them for aggression"
This statement means that they are still obtaining patents, but not showing aggression towards any infringers of the patent? If I am correct in assuming so, then it is useless to them, and goes straight back to our argument of getting rid of these kinds of patents. Maybe there are extremily innovative things that require patents (though I'm not convinced), but things like this, certainly do not fit into that catagory.
