I don't know anything about pharma, but having worked in tech and had my share of patent lawyer meetings, it sure doesn't seem like software patents are necessary at all. That said, a patent system has a lot of free parameters that you can dial to reduce the cost. At the silly limit, if patents were only good for 24 hours, the cost to society would be ~zero (though also the benefit would be zero), so it's hard to call that "evil" in the sense of definitely causing a lot of harm. The question becomes whether/when you can set all the free parameters to something worth having.
