With background summary of chess variants.[All Comments] [Add Comment or Rating]Fergus Duniho wrote on 2011-04-13 UTCI just checked on the status of this patent, and I found 5690334 in a list titled 'PATENTS WHICH EXPIRED ON November 25, 2009 DUE TO FAILURE TO PAY MAINTENANCE FEES.' So it looks like the patent has expired. Unless George Duke provides evidence that the patent is still in effect, I will lift the ban on playing Falcon Chess on Game Courier.
