II. WHAT IS A TRADEMARK ASSIGNMENT?

A trademark assignment is the transfer by the original trademark owner of ownership rights in its trademark to a new owner. This is a common transaction entered into by many organizations and individuals. The assignment must be effected by way of a written trademark assignment agreement.

Please note that although a trademark assignment reflects the mutual intention and agreement of both the assignor and the assignee, the assignment procedure remains subject to State administration. Accordingly, the trademark assignment agreement must be registered with the competent State authority.

• An industrial property right holder may assign its rights only within the scope of protection granted to such rights;
• A trademark assignment agreement shall take effect only upon completion of its registration with the industrial property rights authority in Vietnam, namely the Intellectual Property Office of Vietnam;
