It's time for me to hand in my patent again. I don't know how much to pay this year. How to check online and how to pay online?

I don't know which country your patent comes from. If it is from China, you can go to the website to check the patent examination in China, and enter the application number and verification code to check the fee.

Payment method is as follows:

The payer may pay the patent fee directly to the Patent Office or the agency of the Patent Office. Please visit /zldbc for information about the patent office agency.

Users who apply for electronic registration can log on to China Patent Electronic Application Network () and use the online payment system to pay patent fees. Among them, individual users can use the bank card payment method, and patent agencies and users of enterprises and institutions can use the enterprise account payment method.

The payer can also remit the patent fee through the bank or post office. When remitting patent fees through banks or post offices, the correct application number (or patent number), fee name (or abbreviation) and amount shall be stated in the postscript column of the remittance slip.
