When an individual industrial and commercial household applies to the registration authority for name change registration, the name of the business license of the individual industrial and commercial household is changed, which has nothing to do with the trademark used by the individual industrial and commercial household. No matter how individual industrial and commercial households change their names, the right to use trademarks will not change, and the name of trademarks does not need to be changed. Therefore, individual industrial and commercial households do not need to change their names and trademarks.
