Under normal circumstances, for relatively well-known trademarks, you will know which company or enterprise's trademark it is. If you really don't know and want to know, you can go to the Trademark Office to search, you can check it yourself, or you can Entrust an intellectual property agency service company to help you check, and you only need to pay a small service fee. A trademark is a symbol of a company or its products. It is an intangible asset of the company or company. It must not be copied or counterfeited, as this is an infringement.
