You get a design patent for the creative aspects of your product such as the design, the colour or the shape. The design patent is important for manufacturers of industrial design like furniture or kitchenware because industrial design usually does not obtain copyright protection.
A further advantage of the design patent is that it can also be filed for very simple creations like simple pattern of hangings. When the design patent is registered you have the same rights like a copyright owner.
Important: Your design has to have a specific characteristic and it must be new to be valid. The application is possible with the German patent and trademark office or the trademarks and designs registration office of the European Union.
