What are the problems in patent correction?

(1) If the modification is made by means of correction, it is best to unify the description or claims first, but try not to expand the scope of protection when modifying the claims.

(2) In addition to the modification, you should also submit the modified reference page of the modified file (that is, let the examiner know where the modification is made, delete it with strikeout and add it with underline) and the modified clean version (replace the page, and the unmodified part does not need to be submitted. It should be noted that if your modification leads to different page contents, it should be submitted. If only the third paragraph on page 2 of the description is modified, the fourth paragraph and the following contents will not be changed. If there is something on the page that reaches the third page, you only need to submit the second page, but if there is something on the page that reaches the third page, you need to submit the second and third pages. The safest way is to submit the revised whole document. )

There is no need to submit the request again unless the request is also modified.
