I read through the emails, and I believe I'm mistaken: nothing is specified on whether or not OpenMW is a cleanroom implementation. My point stands, though. If Bethesda can show that OpenMW was in any way borne from reverse-engineering their engine code, and that their code was patented, then they would have an IP claim against OpenMW.
