The Turkish Patent Office (TPI) conducts substantive examination of invention patents and formal examination of utility model and design patents.
Turkey's patent law defines design as: "Design refers to a new design that is aesthetic and suitable for industrial application based on the shape, pattern or their combination and the combination of color, shape and pattern of a product."
The protected new design should be original. For complex product design, only the appearance design is novel and original can it be protected.
