When will the patent application fee be paid?

1. The time to pay the patent application fee is two months before the filing date after receiving the patent acceptance notice. 2. When paying the application fee, you must indicate the patent application number and the name of the fee. The application number is on the patent acceptance notice; 3. The Patent Office will examine your patent only after paying the application fee. If you don't pay the application fee, your application documents will be left unchecked and destroyed one year later. 4. After passing the examination, the Patent Office will send you a patent authorization notice (that is, the application you mentioned). After receiving it, you need to pay the certificate fee and the annual fee for the first year; If the examination fails, it means that you have not applied, so you don't have to pay the certificate fee and the annual fee for the first year. In other words, the application fee must be paid, and there is no need to pay the follow-up fee without applying.
