There is so much confusion about patents. There are many myths constantly circulating that just aren't true. It's not extremely expensive, the originator of the invention is the patentor (typically). There are two type of U.S. patents. etc. etc. etc....
If your are truly interested in learning about patents (U.S.), go get the book "Patent it yourself" by David Pressman. The "common sense" information that floats around is just totally wrong. -Cary P.S. I know these things because I wrote and acquired a patent when I was 18.
