    Hi deni62,
    Under some circumstances, patent laws allow an inventor to patent a modification or upgrade to an existing device.  But, there has to be a substantial upgrade.  Typical example is the tale of an inventor named Gilmore.  He came up with a modification to an existing carburetor for an aircraft engine.  His patent request was turned down though by the patent office.  They did not feel there was a substantial difference between the existing carburetor and his modified carburetor to justify a new patent. nevadascul2007-5-22 15:30:29
