Legal analysis: there is a time limit for the inheritance of trademark rights. You must apply to the State Trademark Office for the transfer of the exclusive right to use a trademark within one year from the date of the death of the registered obligee, otherwise, you may lose this legal right after the deadline. The successor inherits the exclusive right to use a trademark within the validity period of the trademark. Upon expiration of the registration period, the successor may apply for renewal and continue to enjoy exclusive rights. If the successor fails to apply for renewal, he will lose the exclusive right to use the registered trademark.
