The corrected content can be marked or not. If marked, the examiner must fill in another form "Telephone Discussion Record". If there is no tag, this table will be omitted. If the content you modify involves substantive issues of the patent law, such as disapproval, lack of publicity, novelty or creativity, the law stipulates that telephone discussion is not allowed, but some examiners are afraid that you will not change it, so it is better not to mark it.
