The patent technology disclosure document is given to the entrusting agency. The agent will need a few days to submit the patent to the State Intellectual Property Office.

Usually, patent agents need to prepare patent application documents based on the technical content of the technical briefing. The time depends on the completeness of the technical content, or as agreed in the patent agency contract.

Generally, it takes three or four weeks. If you need to add technical content, it will be longer, maybe a few months.
