Design is defined by the visible appearance of a product. Even if a product has a technical function, only its appearance is protected by design protection. The goods can be both handmade and mass-produced. Examples of goods that can enjoy design protection include furniture, clothing, packaging, machinery, tools, foodstuffs and jewellery. A product need not be in three-dimensional form to enjoy protection. It can be two-dimensional, such as a screen display on a computer, a graphic symbol, or a decoration on another product, such as wallpaper. The more original and innovative the design is, the greater protection.
