- Le_Roy_v._Tatham abstract "Le Roy v. Tatham is an 1852 decision of the United States Supreme Court holding that a principle in the abstract cannot be patented, and no one can claim in it an exclusive right. The inventors had discovered the principle that hot, but congealed, lead under pressure would re-unite as an unbroken solid material, which permitted manufacture of a superior lead pipe. The apparatus to make lead pipe was old and obvious: the inventors, by making slight changes in the old machinery to provide sufficient heat and pressure to remelt the lead, in effect, invented a new use of an old machine. The claim was to the old or obvious apparatus (as an apparatus) \"when used to form pipes of metal under heat and pressure in the manner set forth or in any other manner substantially the same.\" It was not lawful to patent the old apparatus again, however used, so that the patent amounted to an attempt to patent the principle. That made the patent invalid.".
