I am confident that the Big Pharma's are very well aware of Regen's HUGE biotech, they are well smart and very aggressive. Your emailing them details on Regen's biotech, patents etc in my opinion will not do anything, it will be a waste of your time. Koos still has to activate the expired patents, which will take good amount of time, plus they have to get the $50 million equity, that we all know they are waiting on. Koos also has to do a lot of other stuff. Why the Regen buyout has not happened so far, has any BPs approached Regen for a BP, what buyout value/bid did they offer to Regen, and a number of other questions are all anybody's speculation/guess. Maybe they haven't found what they were looking for in Regen, also maybe they want to buy Regen much cheaper. The BPs are very greedy and will buyout HUGE BIOTECH for cheap. The buyouts take time, and I would be very surprised if it happens in a year or less from now. JMHO
