How to get a receipt from the patent office after paying the annual patent fee through bank remittance? Are there any detailed steps?

After the general bank remits money, it is necessary to fax the remittance receipt to the toll office of the Patent Office with the fax number of 0 10-62088065 or 620873 12, and then dial 0 10-62088028 or 8029 for manual confirmation.

Then you have to wait, and it will take at least three weeks to receive the invoice.

You can call the Patent Office hotline: 0 10-62356655 for more detailed information.
