How to write the correction date of patent request

1, the supplementary patent number must be consistent, which is the only means to identify the application before authorization. Where the application has gone through the formalities for changing the description item, it shall be filled in according to the contents approved by the Patent Office.

2. In general, the name of the invention in the supplement is the name of the original application, but if it is the name of the invention that needs to be corrected, just write down what changed the name of the invention.

3. Fill in the corrected content: the content to be deleted and the corrected content can be written as two corrected contents, which are clearer and easier to express. If there is a copy of the application document, mark the modified content on it, scan it into a picture and send it as an attachment.

4. Copy of application documents: If it is an electronic correction, it is not necessary to submit this document.

5. When the form can't fit, fill in "see attached page" directly in the form, and then write it in the form of attachment, indicating the first page and the first line, and just modify the contents before and after. It is not necessary to copy all the contents before modification, and the contents that don't need to be modified can be indicated by ellipsis.

6. Modification of the attached drawings: Just write down the problems before modification and the problems eliminated after modification, and then mark the modified places on the drawings before modification when submitting the replacement page.
