Patents are an important part of modern society that allows creators and inventors to maintain the rights to their inventions. Without patents, creators would have no incentive to push the envelope as their ideas would easily be stolen. 

But today we have a different problem. Patent trolls. Lawyers and firms who attempt to patent any idea they can think of in order to sue other people and companies. And this trend is getting out of control. John Oliver discusses patent trolls in this week’s Internet segment of his late night show Last Week Tonight.
