If you register black and white when applying for registration, you can change the color. The font cannot be changed. One trademark can only have one pattern. You can specify the color or not. If you don’t specify, you can change it. Font is not specified. According to the provisions of Article 44, Paragraph 1 of the Trademark Law, if a trademark registrant changes the words, graphics, or combinations of its registered trademark on its own, it is an act of changing the registered trademark without authorization. Adding a registration mark to a trademark that has not been approved for registration, including using the trademark and adding a registration mark on other goods outside the scope of goods for which the registered trademark is approved, is an act of passing off a registered trademark. So, how to grasp and distinguish the relationship and boundary between "changing the text, graphics or combination of registered trademarks on your own" and "counterfeiting registered trademarks"? This needs to be determined on a case-by-case basis for specific trademark cases, but the basic principle is: make partial or minor changes to the registered trademark (such as changing the font of the text part of the trademark, or making some changes to the graphic part without changing the main body of the graphic) or addition or deletion, etc.), it is an act mentioned in Article 44, Paragraph 1 of the Trademark Law; but if a major or fundamental change is made to the main part of the registered trademark (including words and graphics), then The trademark should be regarded as a new trademark. If the trademark is used without registration and a registration mark is added, it is an act of passing off a registered trademark and will be investigated and punished by the industrial and commercial department. Therefore, a new application for registration should be made.
