If the style of the registered trademark is changed after the trademark is submitted, a new registration application for the new trademark needs to be submitted. If you need to add a logo now, there are two ways:

First, register the logo separately. After the registration is completed, it can be used in combination with the previous trademark, or it can be used alone;

Second, register the combination form after adding the logo. It is recommended to use the first method, which is more flexible in use.

A trademark is a mark that distinguishes the source of goods or services. A trademark is a kind of mark, but it is different from a mark. Only marks that meet certain conditions can be used as trademarks.

Trademarks should meet the following conditions: (1) Trademarks must be associated with specific goods or services; (2) Trademarks must be visible, including text, graphics, letters, numbers, three-dimensional signs and Color combination, as well as the combination of the above elements; (3) The trademark should have distinctive features.

Marks with these elements can distinguish one company's goods or services from those of other companies. Therefore, the complete legal definition of "trademark" should be: words (including letters, letters, letters, etc.) with distinctive features used by producers (including manufacturing, processing, and selection) and operators of goods on goods or packaging and containers of goods. Numbers), graphics, lines, three-dimensional logos and color combinations, as well as combinations of the above elements, are visual signs used to distinguish one's own goods/services from those of others.

The logo design fixes specific things, events, scenes and abstract spirits, ideas, and directions through special graphics, so that when people see the logo, they will naturally associate it with each other and thus have an understanding of the logo. Enterprises generate recognition. The logo is closely related to the operation of the enterprise. The logo is an indispensable element of the enterprise's daily business activities, advertising, cultural construction, and external communication.

So when registering a trademark, you must submit a logo.
