When was the patent accepted?

The application for this invention patent can not be found on the website of the Patent Office, indicating that the Patent Office has not made an initial announcement, which may be due to several reasons:

1) failed in the first trial.

2) The applicant did not ask for early disclosure, so it will take 18 months from the date of the first disclosure of the application.

3) The patent application number is wrong, please check it.

In addition, please note that the substantive examination stage is not entered until the initial disclosure, and there is a notice to enter the substantive examination stage. The payment of the substantive examination fee does not mean that you will enter the substantive examination stage.
