Do I need to pay an application fee for the reexamination of the invention patent?

1. If the service invention application fee is reduced or exempted, 70% of the fee (including the application fee, the actual examination fee and the annual fee for the first three years) can be reduced or exempted; If not completely exempted.

2. Just fill in the substantive examination request, and nothing else needs to be submitted. (If the applicant's patent has been published before, it is equivalent to being published, and the prospect of authorization is worrying! )

There is no need to apply for priority if the patent results are not particularly urgent.
