What is protected

The shape, pattern or colour giving a product a special appearance, usable for industrial or handicraft products. Function is not protected.

Novelty before filing

Designs already public before filing may lack novelty; file before launch.

Drawings

Prepare consistent views showing the whole design; the drawings define protection.

Term

Ten years from filing, non-renewable, subject to the prescribed fees.

Combine with other rights

Logos on products belong in trademarks; artwork may be copyright. Layered rights broaden enforcement.

Foreign priority

A first filing in a Paris Convention country may support a priority claim within the deadline; check the original date first.
