This time its Autodesk Canada doing the suing, claiming that the user interface of Assimilate's Scratch post-production film editing software is too similar to that of Cyborg. Says Assimilate:
Although Autodesk does not market or sell the Cyborg product, Autodesk claims that it purchased the rights to Cyborg in 2002 from the liquidation sale of 5D Solutions.
Wow: Suing somebody for something that looks like something nobody sees.
It turns out that Scratch's UI was not particularly "stolen" from Cyborg, because the two have the same father: after 5D went bust, its owner started again from scratch (pardon the pun). The technology, however, is different: Cyborg is (older) node-based while Scratch is (newer) pipline-based.
