"The three-dimensional marks are a new class of registrable trade marks introduced in the revised Chinese Trade Mark law as of 2001. Corresponding provisions were set forth with regard to the examination of three-dimensional marks in the Trademark Examination Standards issued by the Trademark Office and Trademark Review and Adjudication Board (TRAB) in 2005.
