A registered three dimensional trademark protects the distinctiveness of the sign as regards other existing signs in use for the same products or services. On the other hand, the design protects the novelty and the individual character of a product. Accordingly, the characteristic of novelty does not apply in the case of a trademark. Again, the characteristic of distinctiveness does not apply to a design. A trademark registration period has not time limit, while a registered design has a maximum registration period of 15 years.
