If the company name has the same name as the trademark and the trademark owner already legally owns the trademark, then using the company name for commercial activities does not necessarily constitute a trademark violation. This is because the company name can be regarded as a part of the company in law, and the trademark owner will usually use the trademark as a part of the company name to protect its trademark rights. However, if the company name has the same name as the trademark owner's trademark and the trademark owner does not legally own the trademark, using the company name for commercial activities may constitute trademark copyright violation. This was because if the company name was used to violate the rights of the trademark owner, the trademark owner could pursue the responsibility through legal means. Therefore, in order to avoid unnecessary trouble, the company should carefully consider using the company name to avoid violating the trademark rights of others.
