It is not clear whether Liu Fu Jewelry Light, Shadow and Gold Technology has relevant patents. The light, shadow and gold technology of Liu Fu jewelry is a technology independently innovated by the company, which is extremely unique and innovative. The patent application process of technology is complicated, and related fees need to be paid, and the patent right can only be obtained after examination and approval, authorization and other links. Therefore, even if the light and shadow gold process of Luk Fook Jewelry is not patented, it will not affect the value and innovation of this technology. Light, shadow and gold technology has become the brand symbol of Lukfook Jewelry, which can bring unique and beautiful jewelry design to consumers, so it still has high market competitiveness. Liufu Jewelry is one of the famous jewelry brands in China. Founded in 1987 and headquartered in Shanghai.
