There are patents for invention, utility model and design. Invention patents have the highest technical content, and inventors spend the most creative labor. New products, their manufacturing methods and usage methods can all apply for invention patents. As for the design patent, as long as it involves the shape, pattern or combination of the product, and the combination of color and shape and pattern, it is aesthetic and suitable for industrial application, you can apply for the design patent. As long as there are some technical improvements, you can apply for a patent for utility model, but only in cases involving product structure, shape or their combination.
