Can I apply separately after paying the registration fee?

According to the patent examination guidelines of China, the applicant shall file a divisional application before the expiration of the 2-month period (that is, the time limit for handling the registration formalities) from the date of receiving the notice of China National Intellectual Property Administration granting the original patent right at the latest.

After paying the registration fee of the original application, you can still file a divisional application within the above time limit. In addition, before the original application is rejected and takes effect (including within 3 months from the date when the applicant receives the rejection decision, during the review period and during the administrative proceedings), an application for division may be filed; Before the original application is withdrawn and the original application is deemed to be withdrawn (including the recovery period), a divisional application may also be filed.

It should be noted that the filing time of the applicant's divisional application is reviewed according to the original application, except that the applicant submits the divisional application again according to the examiner's opinion because of the single defect of the divisional application.
