First of all, Happy Christmas to anyone reading my post. I would like to know, if i have the hoover shampoo-polisher spares remade, like the gears, shampoo brushes, tanks etc. Would i violate any patent laws? Or would the patents have already expired? Here in South Africa we have so many hoover machines still running, but the brushes and spares arent available anymore. Im thinking of having moulds made for the shampoo dispenser tank and shampoo brushes.
