Company patents
SEOUL SEMICONDUCTOR CO., LTD.
SEOUL SEMICONDUCTOR CO., LTD. shows a surprising shift in its patent strategy, with a significant decline in its long-standing focus on "LED & Optoelectronics (Legacy CPC)" which saw a -100.0% YoY drop in 2026 (so far), while simultaneously emerging with a strong focus on "Light-Emitting Devices (LEDs)" which accounts for 24.3% of its portfolio and only began appearing in 2025. This indicates a strategic pivot within the LED space, moving away from legacy classifications towards newer LED technologies, despite a general slowdown in patenting activity across most categories so far in 2026.
