AFAIK IIRC A Inc doesn't own anything but only holds licences for IP and trademarks (could be wrong though).
A quick check at the US Patent and Trademark office can clear this up:
Amiga Development LLC LIMITED LIABILITY COMPANY DELAWARE 600 North Derby Lane North Sioux City SOUTH DAKOTA 57049
This address, BTW, belongs to Gateway. It also is an amendment to the original filing:
COMMODORE-AMIGA, INC. CORPORATION CALIFORNIA 983 UNIVERSITY AVENUE LOS GATOS CALIFORNIA 95030
There is also a trademark for "Powered by Amiga" also owned by Gateway.
So, I think you're right there odin.
