@AbouBenAdhem you can patent how you make rats and knock out mice, so kind of, yes. But not necessarily the living organism. The mice have been genetically altered to “knock out” genes (strings of dna that code for a protein). The organisms - the mice with the knocked out genes- are licensed as research materials. That is my understanding.
Notwithstanding all of that, creating clones of woolly mammoths is a spectacularly bad idea and probably unethical. WTF are you going to do with one if you succeed? @btaf45
