PBT2 from the Doherty Institute news site., page-30

Pivalde, Prana owns the patent. What's to negotiate? If there are any negotiations going on your owner group has not been informed, and how can anything be accepted from the position of mushroom. A patent is only as good as how far you are prepared to defend it. Legal fights are sometimes necessary, like when Prana finally settled the CQ IP question with Gerolymatos back in 2004.
Where are you getting the info on the many who want to get part ownership? I find that interesting since UQ publicly stated on their website that with any discoveries with the donated drugs, the IP would remain with the donor companies. I think MGH/Harvard, CSIRO and UM own a little of PBT2, but not sure.
