The real question (that has never been answered) is if Escom or Gateway never truly owned the rights to Amniga OS how could they be re-assigned. And Bill's contract with Gateway was a license for trademarks, not a contract transferring ownership of intellectual properties. Several other companies had licensed or even acquired co-author status on the Amiga operating system well before Amiga Washington had incorporated.
Amiga Inc.'s claim to ownership to AmigaOS is highly suspect and the court settlement between Amiga Inc. and Hyperion does little to clear up this ambiguity. Instead it just solidifies Amiga Inc's claim over OS3.1 and Hyperion's right to use 3.1 to develop 4.0 and beyond.
In a word, it is a shared agreement/opinion between both entities of questionable validity.
Maybe it's quite easy: Hyperion Entertainment has (more or less) the rights for AmigaOS and this will be the base for further versions of AmigaOS.
Let's assume that AmigaOS has a great chance to become the major OS of the world - in that case some guys may claim this or that but hopefully then real Amiga (for instance Hyperion Entertainment and A-EON Technology) has enough good support to tackle them.
Real Amigans with rights will happily see AmigaOS prosper and give their right or a licence to Amiga for some money - no problem there.
If there is someone with a serious right who likes to hamper Amiga he'll get trouble (lawfully). If he has support from big guys (like MS), the case may escalate further ... maybe as far as Eurasia vs. USA (if you don't give us this you won't get that) and guess who will win. This may sound silly but if someone is not content with some Millions (for some stuff he hasn't done much for), there must be a reason.
