Then click "Add" and select the application for actual review.
Fill in the contents and add the electronic version of the amendment to the attachment list. Save.
Click Add again and select the correction book.
Fill in the contents and make corrections. Document: claim, location: claim * * *; Before modification: None. After revision: added. Do it. Then the attachment list says, claim, electronic parts.
If you can't get the corrected contents directly from the original application documents, you'd better submit an opinion statement and explain the reasons for the correction.
In addition, if your newly added claim is not recorded in the original claim, the examiner will probably not accept it.
