Can the patent application documents be modified?

According to the regulations, if you want to take the initiative to modify it, you need to do it within two months from the date of application. Now, it is not too late for you. You can actively modify, fill in the addendum, choose to actively modify, and then submit the modified replacement reference page and the modified replacement page in duplicate. Note: the revised content cannot exceed the scope of re-application, and there can be no new content. If there is any new content, it is out of scope revision. It may not be accepted or even invalid. If you want to add something new, you can submit a new patent application. In the case of submitting a new application, if you want to protect the previous application at the same time, you should submit the latter application separately and pay the fee for the previous application. If you don't want to keep the former one, then claim the priority of the former one when mentioning the latter one. Very specific, but hello me.
