Their IP is so great that any external companies to look at it have walked away (remember Lufthansa and Macquarie just to name two?), except possibly Reliance but then we aren't really sure what is happening there atm as there have been no updates despite the timeframe for commissioning of their trial plant having pssed.

IP that is so great that according to the audited reports are still to produce ANY sales or even a stockpile of products to sell.

IP that is so good that AEB are looking to other companies and their IP to try and come up with something that they can sell?

Yep lots of great value in AEB.
