Once the trademark is accepted, they can revoke your trademark objection application within the announcement period. Second, about ten months after the application. They said three months, but they were bluffing. They can take the prior right of copyright as the objection reason, and we need to make an objection reply according to the actual situation.
It is unreasonable to lose money, because there is no infringement and copyright infringement is conditional.
Cheating in this way is very common now.
Although the answer is not comprehensive, I hope I can help you.
