A patent for improvements in the destructive distillation of shale or other oil-yielding minerals, and in apparatus therefor. The use of hot residuum of shale for fuel was known before. The Court held the claim did not embrace two separate inventions, but the improvements in the distillation effected by means of the use of the apparatus in the way described; and that the plaintiff did not claim the use of the hot residuum of shale as fuel, which, if he had, that use being known before, would have vitiated his patent.
This case was affirmed on appeal (W. N. 1883, p. 33). But if an inventor claims in his specification an invention Where a part of and its parts, one of which is already known, if that part claimed is not is to be used only in conjunction with the whole invention, new. and subsidiary to it, and if, after deducting this known part so claimed from the whole invention, sufficient novelty to be advantageous and useful remains, such claim will not invalidate the patent.

A patent for improvements in roller skates by attaching rollers to the foot-stand, with a contrivance by which they could be made to turn in a circle by rocking the foot-stand. The claim for attaching rollers to a foot-stand was not new, although the mode of making them work was, and the patent was upheld. Frearson v. Loe, L.R. 9 Ch.D. 64 (1878).
A patent for improvements in screws and screwdrivers, the V nick in a screw being already known; but it was held, after striking out the old part, there was sufficient novelty left to be advantageous and useful, and so the patent was supported.
"Within the Realm."
The invention must be new "within the realm," which is defined by section 16, Patents Act, 1883, to extend over "the United Kingdom and Isle of Man," that being the extent of a grant for letters patent under the Act.
The Colonies do not, therefore, come "within the realm" for this purpose.
