Patent right is an exclusive right for the patentee granted by state to use his invention within a certain period. The exclusive right is the most outstanding characteristic of patent right.Double-panting violates not only the regional characteristic and time limit characteristic of patent; what’s more, it destroys the balance system of patent interests between patent developers and the public. The prohibition principle of double-patenting is derived from the characteristic of the exclusive right characteristic.
