The consistent principle of trademark management is to use whatever font you register. However, there are few changes in trademark management (for example, registration is handwritten, but use is printed; Use italics for registration and boldface for use), which can generally safeguard the exclusive right to use trademarks; However, the trademark registrant had better re-register the font form used.

Article 37 of the Trademark Law stipulates: "The exclusive right to use a registered trademark is limited to the registered trademark and the goods approved for use." Therefore, after the text is registered as a trademark, if it is a simplified word, traditional Chinese characters will be used; Or the registered traditional Chinese characters, but the simplified characters are actually used, it shall be regarded as a change of the words, figures or their combinations of the registered trademark, and may be handled in accordance with the provisions of Article 30 of the Trademark Law.

Some people think that registered printed words, especially printed words in letter form, can be expressed in words in use, and font changes in letter form are not only allowed, but also protected in many ways. In other words, if printed words are registered, others will be punished as long as they are the same as printed letters.
