Re: BPUR, Oxy, justification? You claim Dr Natanson owns 50% of the patent in question. Last I checked, he was listed as one on the inventors, which has no relationship to the patent holder. So we have one of 2 scenerios: A) He seriously lied about not knowing of the patent. B) He was just a meaningless co-inventor and your statement is wrong. I actually care little either way on bio-pure, just curious if you can back your claim he has 50% ownership.
