The rights to the Amiga platform were successively sold to Escom, and later, Gateway 2000. Escom had almost immediately gone bankrupt itself (due to non-Amiga related problems), while Gateway decided to keep the patents and sell the remaining assets to a new company later renamed to Amiga, Inc. (no relation to the original Amiga Corporation) in 1999. Amiga also received a license to use Amiga-related patents, which were retained by Gateway until they expired. Amiga Inc. sold the copyrights for works created up to 1993 to Cloanto, and commissioned development of AmigaOS 4 to Hyperion Entertainment.
