Yixiu Intellectual Property has the answer for you!

If only part of the content of the combined trademark is actually used, it will be significantly different from the mark approved on the "Trademark Registration Certificate", which is equivalent to forming a new trademark mark. This is an irregular use.

In addition, if the mark is used on the same kind of goods and the ? mark of a registered trademark is also added, it violates the provisions of the Trademark Law and constitutes "passing off a registered trademark". In other words, only one ? mark can be added to a combined trademark.

The opposite of combined trademarks is that trademarks are "registered separately and used in combination". This is also the choice of most people at present, because although this method will increase the cost, it is more flexible and free to use.

If it is "registered separately and used in combination", please note that either the registration marks are marked separately, or the registration marks are not marked at all. Because after combining two or more registered trademarks, using only one registered mark, or using two or more registered trademarks in combination but changing the approved content of the original registered trademark, will constitute the illegal act of passing off a registered trademark.

Hope this helps!
