I haven't received the notice of patent acceptance or rejection. What's the problem?

First, the notification of acceptance of a patent application will usually be sent to your mailing address within two weeks, and you don't need to pick it up yourself.

second, you can call the patent office.

thirdly, if the acceptance notice is lost, it will not be replaced.

Function of patent acceptance notice:

An application for a patent for invention-creation has to go through many links from submission to authorization before the patent examination and approval procedure can be completed. Acceptance is only the first step in the patent application and the first step in the patent examination and approval procedure. As long as the applicant submits the application documents such as the request, the specification, the appended drawings of the specification and the patent claim in accordance with the relevant provisions of the Patent Law, the Patent Office shall accept it and send the applicant a "Notice of Acceptance". The notification of acceptance gives the application number and application date determined by the Patent Office. The applicant's receipt of the notice only shows that the Patent Office has accepted the application, which in no way means that the Patent Office has granted the patent right for the patent application. Only after the applicant has received the "notice of granting patent right and going through registration formalities" made by the Patent Office, and has gone through the registration formalities on schedule, paid the relevant fees, received the patent certificate, and the Patent Office has announced the patent, can the application be said to have obtained the patent right at this time.
