Also why use the term "Pre-patent exemption" if you also say "That program is not even close to intersecting the intellectual property claimed in the Gothic Chess invention." Why not just say that it's not violating the patent? And any program which works like CapaGNU isn't violating the patent either. This means that people can write engines which play Capablanca chess and allow for arbitrary starting positions because they wouldn't even be close to violating your IP. It shouldn't matter if they were written before or after the patent, because CapaGNU establishes prior-art for this behavior. You can't wish away prior-art by granting "exemptions." I assume that the name "Gothic Chess" is trademarked, you have a lot of copyrighted materials which you sell, and you have good ideas for how to promote Gothic Chess. Why even worry about patenting the starting position?
