The above is the cost of successful domestic application. If it is foreign-related, it will be charged separately, which is much higher than that in China.
Invention patents require high technical content, especially novelty and creativity, and the rights after authorization are highly stable. The protection period is 20 years, and other types of patents are 10 years.
An application for a patent for invention has to go through five stages: acceptance, preliminary examination, publication, substantive examination and authorization/rejection. The writing quality of patent application documents is also high, so the cost and time required are more expensive and longer.
