we don't know if Escom ever owned the copyrights, so we don't know if any of their successors ever owned them...
They sure did, as has been known from official sources for more than 20 years:
...the sale of substantially all assets of CEL, CBM and certain of their affiliates (the "Commodore Entities") to ESCOM AG ("Escom")...
substantially all of their intellectual property, including technology, trademarks (including Commodore's logo and the names "Amiga" and "Commodore"), patents, copyrights... Emphasis added. Source:
