Legal analysis: 1. A lawyer’s letter is a warning in nature. Generally, the right holder entrusts a lawyer to send it to the infringer, requesting the infringer to stop the infringement and compensate the right holder for the loss.

2. After receiving a lawyer’s letter notifying you of trademark infringement, try to check the products you produce and sell against the infringements mentioned in the letter. If there is indeed an infringement, it is best to actively contact the rights owner. Negotiate with the other party or the other party’s lawyer.

3. If it is a product from legitimate channels, you can provide a sales contract and supply list. If you do not know that it is an infringing product, you can just stop selling it.
