Company patents
NICHIA CORPORATION
NICHIA CORPORATION's patent strategy shows a significant shift away from its traditional strength in "LED & Optoelectronics (Legacy CPC)", which has seen a dramatic decline of -100.0% so far in 2026, despite still representing 31.9% of its total portfolio. Surprisingly, while many categories are declining, "Light-Emitting Devices (LEDs)" emerged as a new focus in 2025 with 170 patents, although it has seen a -60.0% decline so far in 2026, indicating a dynamic and possibly re-evaluating approach to its core display technologies.
