According to Article 57 of the Trademark Law, the use of the same or similar trademark on the same or similar goods designated by the trademark involved without the permission of the trademark registrant constitutes trademark infringement and is liable for compensation. Therefore, although only more than 30 copies were sold, it is also a trademark infringement and needs to be liable for compensation.

According to the provisions of the Trademark Law of the State, if the liability for compensation is graded, the claim shall be made first according to the infringement profit, then according to the other party's loss, and then according to the trademark license multiple. Finally, in the case that the above situation is unclear, the court made a judgment of less than 3 million yuan at its discretion.

Under normal circumstances, the amount of compensation for the other party's right to sue will be too high. If it is finally decided, it is expected to be around 20,000.
