The trademark can be used after the trademark acceptance letter is issued. However, the trademark is still an unregistered trademark at this time, and there may be certain risks in its use. The trademark acceptance notice is only a manifestation that the applied trademark has passed the formal examination. Similar trademarks, malicious registrations, and famous brands will be examined in the substantive examination stage after the formal examination. Applications for trademarks that are not in compliance with the Trademark Law will be rejected, and if they are in compliance with the Trademark Law, a preliminary review announcement will be made.

A trademark is a sign used to identify and distinguish the source of goods or services. Any mark that can distinguish the goods of a natural person, legal person or other organization from the goods of others, including words, graphics, letters, numbers, three-dimensional signs, color combinations and sounds, etc., as well as combinations of the above elements, can be applied for registration as a trademark . Anyone who uses the same trademark as the registered trademark on the same kind of goods without the permission of the trademark registrant shall infringe the exclusive rights of the registered trademark and shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or solely be fined. If the circumstances are particularly serious, shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years, and shall also be fined.
