Don't have any links at hand, but during the Escom time their was a dispute with Villagetronic who had a licence (from C=) to produce and sell 3.1-upgrades kits.
The (clueless german) judge couldn't find any evidence that AmigaOS was part of what Escom bought. After that it all fell still, and never resurfaced in RL (while it's still popular on the forums).
