Hello!

Although the rights to the trademark belong to you personally, and the legal person of the sole proprietorship is also you, the company still needs an authorization letter when using the trademark, because the rights to the trademark are not in the name of the company, but in the name of the company. If a company directly uses a trademark, it will involve counterfeiting a registered trademark and will be investigated and punished by the industrial and commercial department. Only with a power of attorney, the company has the corresponding rights to use the registered trademark, so it is best for you to draw up a power of attorney.
