For one of the few times, I agree w/ your point. I suspect, there are some patented designs that are being used (unknowingly) by many of the guys making pot calls...also. It is darn hard to make calls today that someone hasn't tried at some point in time that have been incorporated into a given callmakers call. Copying, to me, is when someone knowingly takes another persons' (unique) idea or design and makes that call and calls it his own. Unfortunately, as angry as that would make someone, it happens all the time.
