1. First of all, you still need to confirm whether the word polar bear has been registered by others, and whether the scope of registered goods is the same as yours. If so, you can't register the word polar bear, even if your graphics are different from others', it doesn't affect that you can't register Chinese characters.

2. If it has been registered by others, then you should register the graphic separately first, and consider adding some words before and after the word polar bear in the future to make it not approximate to the previous trademark, so that it can be registered, which is also a measure to avoid risks of trademarks;

3. If you only register graphics, you can't use polar bear Chinese characters in the future. If you use them, it will infringe on the rights of prior trademarks. It will be very troublesome if you are investigated by the Industrial and Commercial Bureau.
