A more thorough explanation:

A trademark owner is a person or entity that controls the quality and nature of goods or services associated with a brand. This person or entity applies the trademark to goods they produce or uses it in advertising services they provide. Examples of trademark owners include individuals, corporations, partnerships, sole proprietorships, trusts, and estates.

Trademark owners have the right to take legal action against trademark infringement. In most countries, trademark registration is required before pursuing legal action. However, in the United States, common law trademark rights protect unregistered trademarks that are in use. Federal registration is not necessary to own a trademark, but it provides certain benefits, such as a legal presumption of ownership and the right to use the trademark.

For example, a clothing company that uses a specific logo on its products is the trademark owner of that logo. If another company uses a similar logo on their products, the clothing company can take legal action against them for trademark infringement.
