At one studio job, where I was in my last and final interview to be a director - "really, a formality" they said, "you're good as hired"... and at that interview they informed me they knew about a patent I own, and said all I had to do was sign the patent over to them and I'd be hired. WTF?! I told them "no", they said "no job" and I said "good by!" And who was that studio? Vivendi Universal.
