After the startup school in April, I had the opportunity to chat with one of the lawyers who had earlier presented. I asked him about the possibility of a world-wide patent system, where an inventor would file once and enjoy protection the world over. He didn't think that would happen anytime soon, mainly because of the "first to invent" system that US uses vs. the "first to file" that most other countries use.
I guess that dream is one step closer to reality if the law passes. :~)
