What is the specific process and time for PCT patent application to enter the national phase in China?

After entering the national phase, it is necessary to submit a request to the relevant enacting state, start the national phase, start the procedure of seeking authorization in the designated country, and pay the national fee. In addition, the time limit for entering the national phase is usually 30 months or 365,438+0 months from the earliest priority date, and in some cases it is 20 months or 265,438+0 months. Patent offices in various countries independently examine patents according to the provisions of their patent laws, and decide whether to grant the country a patent right. Usually, the procedure and cost of PCT application entering the national phase are not much different from that of submitting a direct application in that country.
