It's perfectly obvious. It's the chief reason the whole topic of software patents has been deeply controversial for so long. You seem to be using it as part of a proof by contradiction: One can unknowingly and accidentally reinvent a patented idea. If that were not tidily excused in practice, software patents would be deeply problematic. ---------------------------------------------- Therefore, it must be the case that unknowing and accidental reinvention is tidily excused in practice. I don't think it works. -Chap
