Legal analysis: A lawyer’s letter is generally issued by a lawyer entrusted by the trademark right holder to the infringer, requesting the infringer to stop the infringement and compensate the right holder for losses. After receiving a trademark infringement lawyer's letter, try to check the products you produce and sell against the infringements mentioned in the letter. If there is indeed any infringement, it is best to entrust a lawyer in time and actively contact the rights holder or the other party's lawyer for negotiation. If it is a product from legitimate channels, you can provide a sales contract and supply list. If you did not know that the product was an infringing product before, you can just stop selling it now.

Legal basis: Article 80 of the "Regulations on the Implementation of the Trademark Law of the People's Republic of China" If you sell goods that are not known to infringe the exclusive rights of registered trademarks, you can prove that you have legally obtained the goods and explain that you provided them If the infringing product is found, the industrial and commercial administration department shall order it to stop sales and notify the industrial and commercial administration department where the supplier of infringing goods is located.
