This story doesn't make sense.  There is a standard of due diligence
leading to a patent application.  I invented something once and we never
filed on it and 5 years later someone else invented the same thing and
got a patent on it.  My patent attorneys told me it was considered an
"abandoned" invention and I was out of luck.  We had to license it back.
It didn't matter if I invented it first.
