Hello, if the trademark is confirmed to be infringing, it can be said that there is a dispute between you and the designer in the contract, and you can file a lawsuit for breach of contract with the court.

Because the purpose of signing a contract is the labor achievement of the contractor, the contractor can only be paid if he has completed the labor achievement. Trademark infringement is obviously an unfinished work, and you can bring a lawsuit to the people's court.

If you can give detailed information, you can give a more detailed answer.
