How long will I be notified after submitting an application for patent modification? Seek a professional answer

Look at the progress of the audit. If you meet a fast examiner, you will receive a reply in a month or two, or apply for the next stage. If it's slow, it's hard to say March or May. If the first amendment is correct, it can be authorized. After the authorization notice is issued, the fee will be paid as soon as possible, and the certificate will be obtained in about 2 months.
