Considered infringement. During the trademark use period, simply changing two words in the trademark, but the entire trademark is still highly similar to the registered trademark, will be regarded as trademark infringement. This is because the trademark law emphasizes the independence and uniqueness of trademarks. Trademarks should be sufficiently distinctive and cannot cause confusion with existing trademarks. Before changing the scope of use of a trademark, registration change procedures must be completed with the Trademark Office.
