Chitec Achieves Another R&D Breakthrough, Expanding Its Global Patent Portfolio Beyond Japan and Canada
Chitec announced that the technology associated with its proprietary high-performance blue light absorber, Chiguard® 9546, has received further international patent recognition with the official issuance of a Notice of Patent Grant in South Korea.
According to the notice issued by the Korean Intellectual Property Office on August 6, 2026, the patent application number for this case is 10-2024-7043037. Following substantive examination, a decision to grant the patent was made pursuant to Article 66 of the Korean Patent Act, encompassing a total of 19 claims.
This Korean patent approval marks another major milestone in the global intellectual property strategy for Chiguard® 9546. Building on previous patent grants in Japan and Canada, this grant from the South Korean patent authority further broadens Chitec’s technological IP protection across key Asian and global markets.
Core Technological Breakthrough: Precise Absorption of High-Energy Blue-Violet Light
The title of the invention granted in South Korea is:
"Blue-Violet Light Absorbing Composition Containing Phenylacrylonitrile Compound, Method for Producing the Same, and Product Containing the Composition." The patent scope covers the blue-violet light-absorbing composition, its manufacturing method, and related applications, with the representative commercial product being Chitec's next-generation organic blue light absorber, Chiguard® 9546.
With the rapid growth of high-resolution displays, mobile devices, and immersive applications such as AR, VR, and MR, optical material requirements extend beyond simple absorption efficiency. The market increasingly demands a fine balance between optical performance, material transparency, color fidelity, durability, and processing adaptability.
Through precise molecular design, Chiguard® 9546 features an absorption peak at approximately 403 nm, enabling targeted filtration of the blue-violet spectrum while maintaining high clarity and low color shift. Additionally, its molecular structure provides excellent photostability and long-term durability, ensuring consistent absorption performance during extended use. Chiguard® 9546 also offers strong thermal stability and solvent solubility, supporting diverse material formulations and processing conditions.
In coating applications, its high organic solvent solubility allows seamless integration into various coating systems, facilitating high-concentration formulations with stable dispersion. In plastics applications, its high thermal stability enables effective incorporation into polymer matrices.
By combining high absorption efficiency, low initial color, photostability, thermal stability, and versatile processability, Chiguard® 9546 offers material designers a highly adaptable blue-violet light management solution.
Target application areas include optical lenses, contact lenses, TAC films, polarizers, display materials, high-performance coatings, and UV-curable systems, helping developers protect optical quality while meeting endpoint requirements for blue light management and long-term durability.
Building Global IP Protection: From Japan and Canada to South Korea
The grant of this Korean patent goes beyond adding another international intellectual property milestone; it reflects Chitec’s ongoing commitment to transforming in-house R&D achievements into robustly protected proprietary assets.
With existing patent protection in Japan and Canada, this newly granted Korean patent further expands the global IP footprint for Chiguard® 9546 technology.
Japan and South Korea represent critical hubs for advanced optical materials, electronics, and high-end display industries in Asia. By continuously building a cross-border patent portfolio, Chitec reinforces its technological protection while establishing a solid foundation for future co-development and commercial partnerships with international optical and electronics manufacturers.
Moving forward, Chitec Technology will continue to advance technological innovation within the Chiguard® product line for blue light management and high-performance optical materials. By strengthening its global IP strategy and integrating material science, application technology, and market needs, Chitec remains dedicated to developing next-generation optical solutions together with global industry partners.
