That's true and this helps big corps but this is one case in politics where I really don't care. Software patents are universally bogus and have no business being enforced. Anything that reduces anyone's ability to sue is good in my opinion. To combat the LLC with zero assets issue, which is a good point, I'd like to see a system whereby they establish standards to pierce the corporate veil and go after personal assets, which they tend to argue in cases where the LLC/corp is essentially just a front.
