Pierre I agree totally. I think companies time an effort should be rewarded but how can a company say they own something that god or in other peoples opion evolution created. Just as an example Du Pont has patitent enzyme from yellow stone that they have not changed in any way. Hell they did not even find them. Some one else found them published them in a scientific paper and Du Pont jumped on the gyser tolerant enzymes. Granted they might make good cleaning products but how can they say they own a piece of nature.
