Yawn. OK, OK, I'll write the patent office and find out what the deal is and why they granted you the patent. Perhaps I'll spend the $2600 or so it takes to fight the patent, but I really don't see what's in it for me, even if I was to win. I suppose I might get some satisfaction in watching you eat crow, but is it worth the time and effort for me? And what if you're right? I'll have wasted my time and money. Instead I think next year I'll finish the garage and instead of the welder and metal working equipment I was going to put in it, I'm going to get wood working equipment and start putting out chess boards and sets. After I start to market them (Interchangable 8 X 8, 8 X 10, and 10 X 10 boards, with lots of extra pieces to play lots of games like Bird's Chess and Ultima), I'll post to this board where they might be purchased at, then you can get your court order delivered to me Ed and I'll read it at my leisure as I profit from my craft and see that my lawyers have the ability to get a cease and desist order on you.
