Anyways, I think the larger point is that patents can be bad, especially for synthetic biology if they cover very enabling technologies (they can be good as well in many cases). The same argument could be made for copyright - however, having both forms of IP protection would probably make things much worse. I'm still of the opinion that it's probably better leaving things be the way they are now.
