Most of the IP that we care about is reaching the end of it's 17 year life, the reason for an OS4 was to maintain control over the OS in case there was any money to be had in it. They threw $25,000 at it, barely enough for a driver let alone an OS.
Should KMOS/Amiga Inc go away (please!) the IP actually belongs to Acer who acquired it from Gateway, it was on an exclusive lease to the prior Amiga Inc, (the one that transfered all it's property to KMOS to avoid paying creditors and debts to previous employees and then hijacked KMOS) there is some question as to whether the lease could actually be transferred or not, but since Acer isn't interested that point is moot.
