>>36735631>How do you sue for an scrapped design?You have copyright even if the thing never sees the light of day. Anywhere that recognizes copyright that I'm aware of, recognizes it as inherent at the moment of creation.
You can and should register it as well so it's searchable for others and you have outside evidence of it from a governmental agency should you need to defend it, but you don't have to.
I'm not saying this is the case as I've never heard of this before and if it is they probably did sell it, but that's how you'd sue.
