I was googling the net as always, looking for some details about the CDTV's CD mechanism by Matsushita when I came across the company TVI
In 2004, they tried to sue Microsoft, apple and several others over "Autoplay", you know the annoying feature of launching a default application from the disc on insertion.
And Microsoft's defence was that Auto-insertion notification and default applications were Prior-Art and their patent was invalid. The prior art they gave was the Commodore CDTV
But it was dismissed 'cos they concluded that rebooting between discs didnt count.
Interesting paper chain all the same.
