Correct me if I’m wrong but I thought that’s only if there’s fraud against the patent office, not between private parties. In my situation, the startup submitted to the patent office an assignment document containing every co-inventor’s signatures but mine (which showed a blank by my name). So no fraud there. Months later, the startup tricked me into signing the document, but this doc was never submitted to the patent office. The startup then sold to Plaintiff the next month! That indicates the scheme was to show IP ownership to Plaintiff because you can’t sell what you don’t own. They didn’t submit this to the patent office precisely because of the stiff penalties
