Commercial variant with new pieces on 10 by 10 and 12 by 12 boards. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]George Duke wrote on 2008-07-26 UTCQuantum Chess patent, 5511793 30.April.1996, is the longest games patent ever, over 100 pages single-spaced, and rivals the longest methods patent in any field. The only longer ones I have noticed are biochemical patents, showing entire lengthy generic chemical structures or gene sequences. The site is usually up but occasionally disappears, as not inexpensive source of large square boards. The main innovation is bowman, or that type of piece, shooting to kill upon stopping, in combination with other variant pieces; but there are hundreds of CVs within its claims of games(unlike say Trice's Gothic's one single rules-set). Predictably Quantum uses all its automatic 20 claims without surcharges.
