There is no such “sealed confidential document that was presented before the courts.” That was made up on twitter to fool the masses. It does not exist. Everything that happened in the bankruptcy proceedings has been documented by the monitor and the courts. They own nothing of value “exclusively” or otherwise.
The $12B contract is now completely dead, but it has been ever since BioAmber was liquidated and could no longer supply the product and meet their end of it. BioAmber went bankrupt with that contract in place and nobody has offered to acquire it throughout the bankruptcy proceedings.
I swear I’ll never use the phrase “you can’t make this stuff up” ever again after being on the OTC. Apparently you can.
