No! A trademark is a name, and other names are not protected at all if they are not registered.

If your trademark is used in all combinations of these names, you can submit it again, but remember that in the future, ABCD must be used together, otherwise it will still not be protected by law. In other words, what is registered is what it is, and if it changes, it will not be protected by trademark law.

Trademark registration is actually easy to understand.

Think of a trademark name, select a category, and then submit a copy of the company's business license. This is a trademark.

If you want to change, you have to submit again.

The same company can submit similar ones.

Graphics and LOGO can be registered together or separately.

Anyway, remember, you can use whatever you register and cannot split it.

If you have registered trademarks for ABCD and ABCD respectively, they can be combined or separated, and the registration mark can be placed on the upper right corner of each one.
