What trademark can be registered in the Trademark Clearinghouse?

The TMCH accepts any trademark which is:

- still valid in the trademark register (not expired, rejected, cancelled or withdrawn)

- in use by the trademark owner, in the class it is registered

A trademark may contain international characters, but not a combination of character sets: a Chinese trademark is accepted, a trademark having both a Chinese word and an English word will not be accepted.

An image trademark is accepted as well, as long as the image contains characters allowed in domain names.

Trademarks containing a dot (.) are not accepted. (Note: TMCH announced in July 2013 that they are working on acceptance of dots as well, as long as the dot is not part of a TLD.)

For more details, please refer to the TMCH Guidelines section 2.2.5 and section 4 (
