1. Eliminate the Doctrine of Equivalents
2. Especially with regards to "after-invented technology"
What 1 means is that if you come up with a way to do the same thing, even if you do it a completely different way, they can still sue you in court and you get to spend a million dollars proving that not only did you not infringe on their patent, you came nowhere near infringing on their patent.
What 2 means is that if someone invents something, and later someone else comes along and invents a better way to do something in the patent, it's still infringement because of fucked up court rulings that basically amount to "boo hoo the poor widdle inventors couldn't foresee this invention and shouldn't be penalized because they didn't think of it." Fuck that, if they wanted patent protection for it, they should have invented it themselves.
