Industrial and commercial punishment and trademark registrant sending lawyer's letter are two concepts. Industrial and commercial administrative punishment is the daily administrative management of the industrial and commercial bureau. When you find that your trademark or your company's trademark is infringed, you stop it, which shows that the industrial and commercial bureau has done something to supervise and manage the market. However, the industrial and commercial bureau does not represent the law, and the losses caused by trademark registrants' infringement will not end because of the fine imposed by the industrial and commercial bureau. The trademark registrant sends a lawyer's letter, mainly to inform you that the trademark registrant's rights have been infringed, and finally to recover the economic losses caused to the trademark registrant when you infringe the trademark rights of others. Therefore, when I don't know the contents of the lawyer's letter, you can only pay attention to the contents of the lawyer's letter in the case of trademark infringement. But you can ignore the lawyer's letter, which does not constitute another infringement. When they find you, we'll talk about the specific requirements. If necessary, please ask a lawyer who is proficient in trademark infringement cases to help you solve this problem. In short, for trademark infringement cases, talk less and read more, so as to avoid the evidence against you being collected by the trademark registrant's lawyer or legal team without your knowledge.
