I haven't seen the reason for the objection yet. Get the objection and reply to the question according to his objection. And state the reasons for your application.

wait patiently, but in the meantime, you can do some preparatory work, such as collecting the time, data and evidence of your first use of trademarks, as well as the time, manpower, financial resources, advertising and other evidence invested.

if the other party is not a well-known trademark, the probability of successful objection is not very high. But it may take some time and cost.
