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. Therefore, it is a consistent principle of trademark management 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. We must adhere to the principle of "the protection of the exclusive right to use a trademark is limited to the registered trademark". On the question of whether the words are similar or not, the protection scope of the standard printed words without originality is smaller than that of other writing styles. Therefore, it is better for the trademark registrant to register word mark with his own style to reflect the distinctiveness of the trademark in writing form.
