Hello, you can register a trademark by yourself or entrust a professional agency to the National Trademark Office. Trademark registration is divided into 45 categories. First, you must determine the product or service category you are planning to apply for, and search to eliminate risks. To apply for a company, you need to prepare a copy of the company's business license, official seal, trademark pattern, and payment fees. For an individual application, you need to prepare a copy of the individual industrial and commercial household's business license and personal ID card, trademark pattern, and related fees.
