What do you mean by change? Has the applicant's name changed? Or should it be transferred to another company or individual? If it is a change, you need to submit an application, a copy of the new business license, and the original certificate of change issued by the industrial and commercial bureau. The change certificate will be issued in about 5 months, and the change will be officially completed. If it is a transfer, the documents to be submitted: an application, a copy of the business licenses of both parties, a copy of the notice of acceptance of the transferred trademark or a copy of the trademark registration certificate. Note: Please ensure that the official seal of the transferor at the time of application is consistent with the official seal at the time of transfer. It will take about 5-8 months to complete.
