Emergency help: what materials need to be filed after the patent application is completed and what can't be handled?

Why don't you try to put each patent in a separate file? The application acceptance notice, the acceptance invoice and other notices issued by the patent office shall be filed. It's best to scan every document and then make a patent application schedule, so that you can know the situation of each patent at any time.

Take your time, as long as you don't lose the file, it's actually very simple.

Your business does sound overwhelming. If there are too many patents, why not buy several large folders and put each patent in a plastic bag in the folder? It is best to arrange the order according to the time of application. Each plastic bag in the folder has a label, which can be labeled with a patent number for easy viewing. Take some time to get it done now, and it will be easy later.
