Generally speaking, the time saved by electronic patent application is the time of receiving notice and submitting reply documents (saving the time of mailing), which is usually faster than paper application.
But also according to other time nodes, such as the time when you pay.
For example, it usually takes 8 or 9 months to get a certificate for an electronic application of utility model, and it may take 9- 1 1 month for a paper application.
I hope it helps you.
