I'm surprised to see them back a system where there are any software patents at all. I wonder if they really think they are desirable, or if this is simply political realism based on a judgement that abolishing all software patents is not achievable.

Five years seems like a very, very long time, it leaves all the short term benefits in place, e.g. muscling out the less-innovative competition. I guess this is by design.

The whole proposal sounds very moderate, really.
