7.4 Conclusion

Comparative research on foreign patents without the foreign priority helps us know the difference between this patents’ maintenance time and other kinds of patents’ well, meanwhile help us know more about the influence for the foreign priority on the patent maintenance time. From above analysis, we could find that the quantities of foreign patents without the foreign priority in USA, Korea and Japan are smaller. Most of this type patents distribute in technological field A (Agriculture), B (Performing Operations and Transporting) and C (Chemistry and Metallurgy, and the majority of applicants of this type patents are from American and Japanese. The maintenance times of foreign patents without the foreign priority granted by USA, Korea and Japan are relatively short, while the maintenance times of foreign patents without the foreign priority granted by China is relatively long.

The maintenance situations of foreign patents without the foreign priority granted by USA, Korea and Japan are almost similar, but it is different for foreign patents without the foreign priority granted by China. This phenomenon maybe relate to the unbalanced development of intellectual property in different countries. American and Japanese have stronger innovation abilities, and the awareness to protect their inventions. What’s more, their well-developed international trades also encourage them to apply for the PCT patents. But in China, the innovation abilities and the awareness of intellectual property protection are relatively weak in that time. Of course, with the perfection of intellectual property system and the reinforcement of intellectual property protection awareness, the gaps of average maintenance time of foreign patents without the foreign priority China and other countries might be narrowed shorten.
