The patent application fee has been paid, and the claim needs to be amended if problems are found.

When making a request for substantive examination or within 3 months after receiving the notice of substantive examination, the application documents may be modified, but it should be noted that the modification cannot go beyond the scope of the description and claims of the original application and must comply with the provisions of Article 33 of the Patent Law. Otherwise, in the actual trial, it will be rejected on the grounds that the modification is out of scope.
