Company A entrusts Company B to develop and produce a product and sell it under the trademark of Company A; If Company B sells Company B's trademark instead, is it an infringement?
What are you selling? For example, you buy popular paper, and then you find that if you produce your own brand, you will earn more. After that, you will buy other people's brand paper and your own. Because you communicate directly with customers, you can recommend your brand to customers. This is not infringement.
