Re: who owns the rights to fly patterns?
I have studied this issue from a balloon artist's perspective. If you publish a completely unique description of how to make a balloon dog then it is legal. If it has been published before then they can sue. You can't copyright a balloon dog or an elk hair caddis, but you can copyright the written and graphical description. I think.
