- foreign patent; patent maintenance time; foreign priority
The foreign priority is close related with the foreign patent. For foreign patents, the number of patents with foreign priority is far more than that of the patents without foreign priority. Because of the different innovation abilities and the unbalanced intellectual property development, the average maintenance time of foreign patents without the foreign priority is shorter than that of the patents with the foreign priority granted by USA, Korea and Japan, while the average maintenance time of patents without the foreign priority is longer than that of the patents with the foreign priority granted by China.
