Tech people I know generally agree that patents and copyright stifle innovation. They may once have helped, but no longer.
Business people I know believe patents help create entrepreneurship. They think about it from a founder's perspective (they haven't founded companies themselves) and think patents would help that person establish a foothold against incumbents. They ask, "Without patent protection, how can someone get paid for their creation?"
As I see it, the business people don't have relevant experience. They're talking about a myth that doesn't exist anymore if it ever did. People who innovate and create have relevant experience and know how patents and copyright are used in practice.
At least this judge understands too. I hope his acts catch on.
The more relevant question seems "Without patent protection, how can patent lawyers get paid?" because patent lawyers is what the system creates, at the expense of technological innovation, as I see it anyway.
