A natural person cannot apply for a trademark.
What you want to ask is that the applicant for trademark registration can be a legal person or other organization, but not a natural person. The applicant for trademark registration can be a legal person or other organization, and so can a natural person. It is because natural persons enjoy their own rights such as name right, name right and portrait right, and can protect their related rights and interests through trademark registration. In addition, natural persons can also engage in self-employment or individual entrepreneurship, and protect their commercial brands and commercial interests through trademark registration.
