Well, and I do not support it. If one is to have private R&D, one would have to recognize its property rights on its results, currently in the form of patents. And "socialized" research is best avoided wherever possible, just like any other 'socialized' approach beyond the minimalist libertarian framework.
They can patent their tests, their treatments, medications, etc, even their created or hybridized genes. Just not the ones found in nature.
We've got patent holders who are gene-squatting to make money rather than doing legitimate research. It's not okay.
For craps sake, someone patented Hep C and now researchers working on treatments have to pay licensing fees to do research. Is it too much to ask that the Patent Office only issue patents for bonafide inventions and not mere discoveries of nature?
