Answer: Hello, modifications to registered trademarks are allowed, but must be carried out in accordance with the law. A trademark that has been changed on its own is no longer a registered trademark, and it cannot be used as a registered trademark if it is changed on its own. According to the provisions of the Trademark Law, after the trademark applied for registration becomes a registered trademark, it must be used in strict accordance with the trademark pattern approved by the Trademark Office and shall not be changed at will. This is because when the Trademark Office approves the applicant's trademark application, it examines it based on the trademark elements in the trademark drawing, and only allows registration of trademarks that comply with the relevant provisions of the Trademark Law. If the registrant changes any element of the registered trademark, the trademark may not comply with the relevant provisions of the Trademark Law or may be identical or similar to someone else's previously registered trademark. If the changed trademark is still marked with a registered mark and used as a registered trademark, it is an illegal act to change a registered trademark on its own as stipulated in this law, and the Trademark Office will order it to correct within a time limit or cancel its registered trademark. If the changed trademark is used as an unregistered trademark, it may conflict with the rights of others' registered trademarks, which constitutes trademark infringement. Therefore, it is still recommended that you re-apply for registration of the modified trademark.
