Can one trademark application cover several classes?
A trademark registration application may be filed as a multi-class application.
How are multi-class applications charged, and can one cover all 45 classes?
The fee for a paper application (per class) is RMB 300 (limited to 10 items in the class; above 10 items, an extra RMB 30 is charged for each additional item). The fee for an online application that accepts electronic delivery of documents (per class) is RMB 270 (limited to 10 items in the class; above 10 items, an extra RMB 27 is charged for each additional item).
A multi-class application covering classes 1-45 may be filed.
Can a class be added to a registered mark without changing the number?
Adding a class requires filing a new trademark registration application, which will produce a new trademark registration number.
Can items be added within a class of an existing mark?
Items cannot be added; please file a new trademark application.
How can a registered mark cover more goods or services in the same class?
Where exclusive rights in a registered trademark are needed for goods outside the approved scope of use, a separate registration application must be filed.
Before registration, can a multi-class application be split into one registration per class?
The classes of a multi-class mark cannot be separated.
How can one class be withdrawn from a pending multi-class application?
For a mark still in the registration process, deleting the items is enough.
Can a registered trademark be divided into two or more marks?
A division application cannot be made for a registered trademark.
Can two registered marks in different classes be merged into one?
Two trademarks cannot be merged into one trademark.
Does registering one item in similarity group 2501 cover the others and block similar marks?
Under Article 56 of the Trademark Law, the exclusive right to use a registered trademark is limited to the mark approved for registration and the approved goods.
If you have registered a mark in similarity group 2501, other applicants' identical or similar marks in that group and in similar groups will not get registered.
What if too many items were selected and the payment notice is high?
In this situation, goods and service items cannot be deleted. You may hold off on paying; the application will then not be accepted because of non-payment. You may file a new trademark registration application and select the goods and service items correctly.
