What should I pay attention to when submitting a patent application?

To apply for a patent or go through other formalities in the Patent Office, you can submit or send the application documents or other documents directly to the Patent Office's acceptance office or any of the above-mentioned patent offices.

(2) A form can only be used for one patent application.
