When will the actual patent trial be heard by the examiner?

Generally, after the preliminary examination and publication, the applicant applies for substantive examination, and the applicant enters the actual trial stage after applying and paying the fee. If Shen Qing is made public in advance from the beginning, it may be possible to enter the substantive review within 4-6 months. If the application for disclosure is not made in advance, then according to the provisions of the Patent Law, the invention patent will enter the disclosure procedure 18 months after submission, and the substantive examination will be after publication. But generally speaking, 8- 12 months is basically enough, and 18 months is less than it.
