Exsanguination incapacitate swine, poultry and domestic sheep, whereas a chemical is used for injured livestock. Continued pumping operation of the heart during exsanguination increases the rate of depletion, and thus hastens death, by raising the fluid pressure of the blood. Because the heart operates like a positive displacement pump, reduction of blood volume will not affect efficiency of cardiac output—deprivation of blood to the heart does gradually result in diminished function, but concurrently with similar death of other parts in the body. Quickly after the animal is incapacitated it is hung upside down by its hind limbs and an extremely sharp
Business method patent patentable per se. However they are patentable if a new method solves a "technical" problem and an apparatus/system is involved. Current US case law "Alice Corp. v.
