I applied for a patent and didn't receive the acceptance notice. What should I do?

Generally, you will receive a notice of acceptance of a patent application as soon as you file an application. I would like to ask if you have received any notice of entering the actual trial or other notices? There are two main reasons for not starting the review: 1, whether to make a substantive review request when applying, if it is not mentioned, it will definitely not enter the actual review, so the actual review request will be made first; 2. If the request for actual trial has been made and the actual trial procedure has been entered, it depends on whether the proposal has entered the review procedure, which will take a long time and depends on the field.
