When applying for registration, if it is registered in black and white, the color can be changed, and the font cannot be changed to a trademark. Only one pattern can be specified. You can specify a color or change it without specifying it. No font specified. According to the first paragraph of Article 44 of the Trademark Law, if a trademark registrant changes the words, figures or their combinations of his registered trademark by himself, 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 is an act of counterfeiting a registered trademark, including using the trademark and adding a registration mark to other goods beyond the scope of goods approved for use by the registered trademark. Then, how to grasp and distinguish the relationship and boundary between "changing the words, graphics or their combinations of registered trademarks by oneself" and "counterfeiting registered trademarks"? This needs to be determined according to specific trademark cases, but the basic principle is to 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 or additions or deletions to the graphic part without changing the graphic subject, etc.). ) is the behavior described in Item 1 of Article 44 of the Trademark Law; However, if the main part of a registered trademark (including words and graphics) has undergone major or fundamental changes, it shall be regarded as a new trademark. If a trademark is marked with a registration mark before registration, it is an act of counterfeiting a registered trademark and will be investigated and dealt with by the industrial and commercial department. So you have to re-apply for registration.
