If the application fee is not paid, the earlier application will be considered withdrawn by the Patent Office and will not be published, which will not affect the novelty of the subsequent application.
However, it is still recommended to adopt one of the following two methods:
1. Claim the priority of the earlier application when submitting. If your application is very important, it is recommended to do this, but you will have to pay an additional priority fee of 80 yuan.
2. Submit a revocation statement through CPC. This helps the patent office save monitoring processes and reduce waste of resources.
