George, I must ask *why* '[c]hanging the board to a superset of '10x10 board' (into 3d)we think now violates USPatent5690334(and other foreign) by legal doctrine of equivalents'? The patent is your patent on Falcon Chess, and I can understand Charles' use of the Falcon piece without appropriate permission is a violation of your patent. However, the wording of your first sentence, quoted above in its entirety, indicates that the board violates your exclusive patent rights. Please clarify this. Thank you.
Joe
