No. Whether a trademark is similar or whether it will cause confusion or misunderstanding is not decided by the trademark registrant.

Trademark Law stipulates that when transferring a trademark, a similar trademark of the same type must be transferred, otherwise your transfer will not be approved. Your agency has completely failed to fulfill its responsibility in this matter.

If the transfer fails, you have no legal liability. It’s just that there will inevitably be losses. The solution is to try to negotiate with Xu to transfer the CDAB trademark together. If that doesn't work, we can only cancel your agreement to transfer the AB trademark and refund the transfer money.

If there is indeed a difference between the CDAB trademark and the AB trademark you transferred, and if the Trademark Office does not approve the transfer, you can still file for administrative review. But it’s hard to say with certainty.
