Company patents
Seoul Viosys Co., Ltd.
Seoul Viosys Co. Ltd. shows a surprising shift in its patent strategy, with a significant decline in its traditionally dominant 'LED & Optoelectronics (Legacy CPC)' category, which represents 48.2% of its portfolio, experiencing an 81.2% drop in 2025 and a 100.0% drop so far in 2026. This is contrasted by an emerging focus on 'Electric Heating & Lighting Control', which despite being a smaller category (3.2% of portfolio), saw a remarkable 300.0% growth so far in 2026, indicating a strategic pivot towards consumer applications.
