There are lot of additional problems though... the way the Patent Office washes their hands and leaves it up to the courts to sort things out etc.
I personally think ALL software patents should be abolished completely. In absence of that, NPE's "non-practicing entities" should not be allowed to hold patents. You need to prove that you are using it (in commerce) to keep the patent. And you should not be able to sell a patent unless it is sold with an existing revenue producing business.
The US system has turned into a joke.
