If you sell a commodity that you don't know is an infringement of the exclusive right to use a registered trademark, you can prove that the commodity was legally obtained by yourself and explain the supplier, and you will not be liable for compensation.

Therefore, it is necessary to find the purchase receipt and provide all the information of the supplier.

After the court receives the court summons, it will usually attach some materials, such as the notice of responding to the lawsuit. It is generally required to submit the defense and the notice of proof within 15 days, and it is generally required to submit the evidence to the court within 30 days. Then, the date of the trial and the court are written on the summons. According to these materials attached to the court, the required materials can be submitted within the corresponding time.
