He probably can get a patent for it. The current USPTO seems to be rubber-stamping anything that will or won't work, and if it's prior-arted back to Gallileio, then so much the better. The more interesting question is what he might be able to get out of the patent, business-wise. Can't answer that one. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
