From that listing one can't conclude that the Amiga operating system would have been part of that buyout.
No, that's not what it says. Often understood in a wrong way, even by me :-D
lässt sich deshalb nicht hinreichend überprüfbar entnehmen, daß die X. die ausschliesslichen Lizenzrechte an dem Betriebssystem erworben hat."
You don't need an exclusive right (ausschliessliches Recht) to license it to other third parties. What the court just said is that the contract doesn't say if there are any other parties left that have the right of distribution on AmigaOS.
That's what the law suit was all about. Some third party was sued because they sold copies of AmigaOS3.1 which according to them was legal as they have distribution rights. AT/Escom said that they have the exclusive rights to AmigaOS. However as the "dumb German judge" decided the contract didn't say that Escom got all exclusive rights with the buyout. Therfore Escom lost the law suit.
This law suit would only matter if nowadays some third party comes and sells OS3.1 and could show some AmigaOS3.1 license agreement from the Commodore era to AInc.
