<i>Odds are the &quot;make a cure from it&quot; part would be a human invention and therefore patentable.</i><p>That&#x27;s a use patent and it&#x27;s inferior to a composition patent.<p>Look at what&#x27;s happening to Pfizer in the UK.  They had a use patent on Lyrica, but no composition patent on it.  That means anyone is free to make the drug.  You can&#x27;t really stop a doctor from using a drug for a certain disease if it&#x27;s freely available.
