How to apply for a PCT patent application and how much is it? How long will it take?

I have answered this question before, and now I will answer it again. PCT is divided into two stages: PCT international stage and PCT national stage. In the international phase of PCT, you can apply directly to the Chinese Patent Office, and enter the national phase of PCT within 30 months from the date of the original claim for priority, that is, enter the single country of PCT member countries. PCT international stage fee: about 15000 yuan in the name of the company and about 8000 yuan in the name of the individual. These expenses will be funded by the Ministry of Finance and local intellectual property offices, which will cost little.
