First of all, you can go to the nearest filing office to file for fee reduction;

Secondly, after completing the filing, when filling out the patent application form, click on fee reduction and all materials will be completed. Just sign and submit.

If the filing is approved after application and you apply for later fee reduction, you can click Active Submit in the intermediate document production, select the case for which fee reduction is required, click Add to search for the fee reduction request form, and fill in the request. Just save and submit the document (this type of filing must be a patent applied for independently. If it is applied by an agency, you can only entrust an agency to reduce the fee)
