How long is the patent protection period in Korea?

1. How long is the patent protection period in Korea? South Korea's patent system is similar to China's, including inventions, utility models and designs. The protection period of Korean invention patents is from the date of authorized registration to the date of "20 years from the date of application". With regard to pesticides or medicines, under certain conditions, the protection period can be extended to five years. The invention patent adopts the system of substantive examination, and the Korean government is requested to conduct substantive examination within 5 years from the date of application and within 25 months from the date of actual examination. The protection period of Korean utility model patent is from the date of authorized registration to "from the date of application 10 year". However, unlike China's utility model patents, South Korea's utility model adopts the examination and registration system, and it takes about 10 months to obtain the license after applying to the Korean government. South Korea's design patent shall take effect from the date of authorized registration and end in 15 years from the date of authorized registration. In the examination of design patents, the South Korean government adopts a parallel way of design examination and registration system and non-examination and registration system for the design of certain projects. 2.

Three, the patent application documents include the Paris Convention and the direct application to South Korea. Paris Convention: After China's application, before the expiration of 6 months from the date of the first prior patent application (i.e. the priority date), when filing an application for a patent for appearance with the same theme with the Korean Industrial Property Office, you can enjoy the priority, and you need to submit the priority certificate.
