Company patents
Self Electronics Co., Ltd.
Self Electronics Co., Ltd. shows a surprising shift in its patent strategy, with a significant decline in its core 'Lighting Devices (Functional Features)' category, which still represents 54.0% of its portfolio but saw an 87.5% YoY drop in 2025. Concurrently, the company is exploring new areas, evidenced by a 100.0% YoY growth in 'Wireless Networks' patents so far in 2026, suggesting an emerging focus on connectivity beyond traditional lighting.
