It also depends on the strength of the other party. If it is a big company, how to use the trademark and so on.
If the other party's strength is not strong, there is a great possibility of successful trademark reexamination.
Ps: Are there any other trademarks cited?
Note: Pay attention to collecting evidence of the use of your own trademark, and advertising is better.
It is normal that some examiners will refuse if possible or similar. If we have to say similarity, we will point out that the inner ring of the trademark is similar to yours, and yours is a triangle without radian, which is a bit far-fetched.
