Trademark registration, graphics and text can be registered together, or graphics and text can be registered separately. Trademark agencies will suggest that graphics and characters be registered separately, not only to overcharge agency fees, but more importantly, because graphics and characters are examined and compared separately when the Trademark Office examines trademarks. When any graphics and characters are the same as or similar to other trademarks, the trademark with graphics and characters is rejected as a whole.
Therefore, although the overall registration saves money, it is very risky. If you register separately, it will cost more money, but at least you can ensure that at least one text or graphic passes. In this way, it is a good thing for trademark registrants.
Also, if you want to change the graphics in the future, and the text and graphics are registered separately, it is convenient to change the graphics.
