Why doesn't the patent business handling system firm need to scan the code to sign?

The reason why the patent business handling system firm does not need to scan the code signature is because it needs electronic signature when submitting certain matters (such as filing a patent application online). However, at present, there are many kinds of electronic signatures in China National Intellectual Property Administration, and scanning code signature is not necessary. Specifically, the electronic signature methods adopted in China National Intellectual Property Administration include digital certificate signature, authorized password signature and unified identity authentication signature. These signature methods can be completed by electronic certificate, password and so on. , there is no need to use traditional scan code signature.
