The split use of a trademark depends on the form in which it was registered. If you apply for split registration when you apply, you can freely combine it into multiple trademarks for use. If you only apply for one combined trademark when you apply for registration, it is recommended not to split it and use it because there is no registered trademark. , using it with arbitrary modifications is an improper use of a registered trademark, and the Trademark Office has the right to correct it. In serious cases, it can also cancel the registered trademark. Legal basis: Article 52 of the Trademark Law of the People's Republic of China: Anyone who commits any of the following acts shall infringe upon the exclusive right to use a registered trademark: (1) Using the same product or product without the permission of the trademark registrant. Using a trademark that is the same or similar to its registered trademark on similar goods; (2) selling goods that infringe the exclusive rights of a registered trademark; (3) forging or making without authorization registered trademark signs of others or selling forged or made without authorization registered trademark signs; (4) Changing the registered trademark without the consent of the trademark registrant and putting the goods with the changed trademark back on the market; (5) Causing other damage to the exclusive right to use the registered trademark of others.
